Observe for transportation:On Maistro 11 and 12 RC slide in the bout markers before folding.Secure the covers of the precision seed drill units on the wings with toggle type fasten-ers.On Maistro 11 and 12 RC retract the precision seed drill unit and secure with the shut-off valve.Connect the road lighting equipment, then check the function and cleanliness of road lighting equipment and warning signs.On the seed wagon insert the aluminium clips to the piston rods of the lift cylinders and lower the machine.On the seed wagon SW 3500 S secure the hydraulic upper link with the shut-off valves.

Secure or lock the hydraulic control units on the tractor.

During transportation the Maistro 11 and 12 RC cause a negative nose weight of up to 1000 kg on the SW 7000 S and thereby relieve the rear axle of the tractor.Choose the tractor big enough, to ensure sufficient steering and braking abilities.

With the Maistro 11 and 12 RC the transport height my be at least 4.00 m, depending on the lift. Before approach-ing bridges or low hanging power lines it may be necessary to lower the ma-chine as far as possible.

Operational safetyThe machine must only be put into operation after receiving instructions by employees of the authorized dealer or a HORSCH employee. The machine registration form has to be completed and returned to HORSCH.

All protective features and safety equipment, such as detachable protective devices, must be correctly in place and reliably functioning before the machine is put into operation.

Check and tighten nuts and screws at regular intervals.Check tyre pressure regularly.In case of malfunctions stop and secure the machine immediately!

Road traffic safetyThe valid road traffic regulations are to be ob-served when travelling on public roads, paths and areas. Do not exceed the max. permissible widths and attach light system, warning and protective devices.Also observe transport height depending on the coupled machine!

Do not exceed the permissible axle loads, tyre carrying capacities and total weights, in order to ensure sufficient steering and braking capa-bilities. Handling is affected by the implement connected. It is important to take into account the large overhang and the centrifugal mass of the implement, particularly when cornering.

The whole machine is to be cleaned of soil that has been collected before travel on public roads.Passengers are strictly forbidden to ride on the machine.!

On public roads travel at a maximum speed of 25 km/h and only with am empty seed hopper.

Accident preventionIn addition to the operating instructions, it is important to observe the accident prevention regulations specified by agricultural trade as-sociations!

Hitching up / unhitchingThere is risk of injury to persons when hitching up / unhitching the machine to the drawbar of the tractor.

Secure the machine against rolling away.Take special care when reversing the tractor. Never stand between tractor and machine.Only park the machine on a firm and level surface. Before unhitching the machine, lower it to the ground.

Brake systemDepending on the equipment, the machines can be equipped with a pneumatic brake system.

For road transportation the brake system must always be connected and fully functional. After hitching the machine and before transpor-tation you should always check the function and condition of the brake system.

The brake has no locking function. Always se-cure the machine against rolling away before unhitching.

In the version with adjustable brake power con-troller the setting must be "full", even when the hopper is empty.

For road travel the hopper must be empty.

Hydraulic connectionsDo not connect hydraulic lines to the tractor, before both hydraulic systems (machine and tractor) are de-pressurised.The hydraulic system is under high pressure. Check all lines, hoses and screwed con-nections regularly for leaks and any visible external damage! Only use appropriate aids when checking for leaks. Repair any damage immediately! Oil sprays can cause injuries and fire!In the case of injury, contact a doctor im-mediately!

Power sockets and connectors on the hydraulic connections between the tractor and machine should be colour-coded in order to exclude op-erating errors.

The control units on the tractor must be secured or locked when not in use or when the machine is in transport position, in order to prevent accidents caused by unintended hydraulic move-ments or movements caused by per-sons other than the operator (children, passengers).

Pressure accumulatorDepending on the equipment of the machine, the hydraulic system may have a pressure ac-cumulator installed.

Do not open or work (welding, drilling) on the pressure accumulator. Even after being emp-tied, the accumulator is still preloaded by gas pressure.

Always depressurise the pressure accumulator before starting work on the hydraulic system. The pressure gauge should not indicate any pressure.The pressure gauge reading should drop to 0 bar. Only then may work be carried out on the hydraulic system.

Changing implementsSecure the machine against unintended roll-ing!Secure lifted frame parts, under which you will be working, with suitable supports!Caution! Danger of injury caused by protrud-ing parts (harrow, tines, share)!Do not use packer tyres or other rotating parts when climbing onto the machine. These could start to rotate and you could fall and be seri-ously injured.

In operationCheck the area around the machine (for chil-dren!) before setting off and starting operation of the machine. Ensure sufficient visibility.Do not remove any of the mandatory and supplied protective devices.Stay clear of the operating range of hydrauli-cally operated parts.Only use ascending aids and steps when machine is at standstill. Passengers are not allowed to ride on the machine during opera-tion!

Service and maintenanceEnsure that regular tests and inspections are always carried out to schedule, as specified in the operating instructions.Prior to performing maintenance and servicing work, ensure that the machine is positioned on firm, level ground and that it is properly secured against rolling away.De-pressurise the hydraulic system and lower or support the implement. Before cleaning the machine with high pres-sure cleaning equipment cover all openings, which should stay clear of water, steam or cleaning agents for reasons of safety or op-eration. Do not aim the water jet directly at electrical or electronic components, bearings or the fan. After cleaning, check all hydraulic lines for leaks and loose connections. Check hoses for chafing and signs of other damage. Remedy any faults immediately!Prior to working on the electrical system, dis-connect it from the electric power supply.When performing welding work on the ma-chine, disconnect the cables from computers and other electronic components. The ground connection must be as close as possible to the welding point.Retighten screwed connections which had been loosened during servicing and mainte-nance work.

Do not wash new machines with a steam-jet or high-pressure cleaner. The paint takes approx. 3 months to cure and could thus be damaged if this time has not yet expired.

Unhitching the MaistroPark the Maistro 8 and 9 RC and the Maistro 6 and 8 CC only in unfolded condition. The Maistro 11 and 12 RC have jack stands can can be parked in folded condition.

Folding the Maistro 12With the Maistro 12 one must strictly follow the correct sequence to fold and unfold, as other-wise parts may be damaged.

FoldingLift the machine completely;Fold the Maistro, keep operating the control unit until the precision seed drill units in the middle are fully lifted;Insert aluminium clips into the hydraulic cyl-inders of the three-point; Lower the machine on to the transport safe-guard (mandatory for transport on public roads);Due to its height do not transport the machine any higher than necesary;Switch over the shut-off valve on the SW 7000 S, so that the precision seed drill unit in the middle can lower;

UnfoldingOpen the shut-off valve on the front of the SW 7000 S.Lift the machine and remove the aluminium clips from the hydraulic cylinders.Unfold the Maistro; Attention! The precision seed drill unit in the middle will drop down first.

Hitching-up the machineThe Maistro RC can be hitched behind a seed wagon or deirectly to the tractor, depending on design.

Depending on the combination of the Maistro on a seed wagon, the following points must be observed.

Maistro 8 RC:The hydraulic metering drive is connected in line with the hydraulic fan. When hitching a new Maistro to an old seed wagon SW 3500 S, the hydraulic system must be connected as speci-fied in drawing 23659300.

Maistro 11 and 12 RC:The jack stands must not be removed. Oth-erwise the precision seed drill unit would be damaged when lowering the machine in folded condition.

Maistro on SW 7000 SThe pivot point must not be set rigid when a Ma-istro is hitched up. The screws must be removed so that the lower links can swing about.

Maistro on SW 3500 SOn a seed wagon 3500 S with rigid lower links only Maistro 8 and 9 RC with hydraulic metering drive can be hitched up.

OperationThe individual drilling modules of the Maistro are flanged to a foldable transverse frame.The metering units can be driven mechanically or hydraulically.

Drilling module Maistro

Seed hopper with cover and lockHandle for drive couplingAdjustment lever for drilling depthAdjustment lever for press rollersPress rollersDepth guidance wheelCoulter discs for seedCoulter discs for fertiliser (accessory)Drive shaft with chain drive

Seed hopper:The seed hopper has a capacity of 67 litres. The cover closes the hopper and protects the seed against contamination. Dust and dirt increase wear and result in metering errors.Foreign objects can block or destroy the meter-ing unit.The covers on the foldable units are secured by a toggle-type fastener. This fastener must be closed to prevent seed from falling out while folded for transport.

Maintenance:The plastic parts of drill units, the seed hoppers, parts of the metering device and the downpipe must not be sprayed with oil, rust remover or any similar substances. These parts would become brittle and break.

Mechanical driveThe machine is driven by a ground driven wheel and a chain drive with changeable sprockets on a central drive shaft.Each metering unit is chain driven by the central shaft.Each metering unit can be individually separated from the drive shaft via a coupling. For this pur-pose pull the handle towards the outside and turn it to lock.

Check the adjustment of each clutch before starting work. With an open coupling no seed will be placed.

Metering drive

Drive shaftDrive chainChange sprocketGround driven wheel

In order to avoid malfunctions during seeding, all components for driving the metering unit must be in perfect condition.

1.2.3.4.

Faults in the drive system can lead to metering errors, to the failure of individual drill units or the complete machine.

Chain and sprockets must not be worn. The chain tensioners must be in good work-ing order.The sprockets must be in line. The coupling shaft must be in line with the metering shaft; Check the fastening, if re-quired.The drive claws of the drive shafts must not be worn and should connect both shafts reli-ably.With mechanical ground driven wheel install max. 2 coulter compression springs to avoid slippage of the drive wheel and to ensure traction.

In connection with the DrillManager monitoring the drive shaft is recommended.

Setting the seed quantityThe seed quantity is specified in the distance between grains in centimetres or by the number of grains per hectare.

To adjust the metering quantity determine the appropriate sprocket from the table (row spacing 75 or 70 cm) and install it on the drive wheel.

Take the selected sprocket out of the bracket on the frame.Remove the cotter pin from the drive wheel and pull off the old sprocket with the chain.Lay the chain around the new sprocket and push the sprocket on the drive shaft. If necessary rotate the drive shaft and insert the cotter pin.

Install the same ratio on all machines and on both drive wheels.

Hydraulic driveWith the hydraulic drive, a hydraulic motor drives the drive shaft via a chain drive. The hydraulic motor is driven by the hydraulic pump in the tractor and controlled by the Drill-Manager ME according to the desired number of grains.

Hydraulic motor

All other drive components are identical with the mechanical drive. The adjustments for the hydraulic drive are de-scribed in the instructions for DrillManager ME for the Maistro.

Adjustment table seed quantity for 70 cm row spacing

Sowing speedThe sowing speed can range from 3 to 10 km/h. The actually possible speed depends on the metering quantity (see table), the size and shape of the seed and the field conditions.

Exceeding the specified sowing speed will result in an increased number of metering errors. The fingers may lose an increased amount of grains or, particularly with small seed, take on several grains.

The highest accuracy is achieved with medium size and round seed when working with the specified speed. Larger seeds are sown more accurately at higher speeds.

The speed must not be too slow.

The metering shaft should not fall below 40 revolutions per minute, but should not exceed 80 revolutions per minute.See shaft speed display.

Seed controlIn order to control the number of seeds, the press roller on one or several drilling units can be tied up to the hopper frame with a strap.This keeps the seed visible for checking and counting. If necessary reduce the drilling depth on these units.

Travel a short distance under normal sowing conditions. Then measure 1/1000 ha. With a row spacing of 0,75 m this is a length of 13,33 m.

Count the seed along this stretch and multiply by 1000. Compare this amount with the meter-ing table. The deviation should be as small as possible.

In case of deviations:Check the coulter pressure; possibly too high slippage on the drive wheel caused by a too high coulter pressure.Check the transmission ratio on the chain drive.Check drive shaft, drive chains and sprock-ets.Check the air pressure in the drive wheel.Check fingers and mechanics on the meter-ing wheel.

Setting the sowing depthDuring sowing the frame rests on the support wheels and the ground driven wheel (mech. drive) with its deadweight and presses the coulter discs into the ground, until the depth guidance wheels have ground contact.

Adjusting the coulter pressureTension springs on the parallel guide transfer additional weight from the frame to the precision seed drill units.The tensile force of the springs can be changed by choosing different attachment points.

Extra springs may also be hooked in, depending on the design.Ground driven wheel max. 2 springs Hydr. metering drive 4 springsWith precision drill unit retraction max. 3 springs

The top parallel guide and the spring holder have two holes each to adjust the spring force.Form these adjustment possibilities you must find the right combination to suit the soil condi-tions.

The further back the spring is hooked in, the more weight is displaced to the precision seed drill units. The open sides of the springs must face towards the seed hopper.

Adjusting the coulter pressure

Adjust the coulter pressure equally on all spring holders of the machine.

Adjusting the coulter pressure:Lift the machine;Pull the bolt out of the spring holder;Slide the spring holder with the spring to the desired position;Insert the bolt in the new position;

The coulter pressure should not be set higher than necessary. Under no circumstances should frame and drive wheel be unloaded to such an extent, that meter-ing operation is no longer assured.

Check the seed placement with every change of coulter pressure. Any change can affect the seed placement.

Coulter pressure

Coulter pressure:in kilogram with horizontal parallel guidance and empty hopper. The drill unit presses with a deadweight of approx. 100 kg on the coulter discs.

Pos. 1 spring 2 springs1. 120 1402. 134 1623. 162 2304. 190 270

Adjusting the depth guidance wheelsThe drilling depth of the coulter discs is limited by the depth guidance wheels. The drilling depth can be adjusted in 16 steps from approx. 1.5 cm to 9 cm.

Lever for depth adjustment

Adjusting the drilling depth:Lift the machine;Press the adjustment lever down and push it to the desired position; The further the lever is pushed forward, the shallower the drilling depth;Let the adjustment lever click into place in the new position;

Set the drilling depth equally on all precision seed drill units.

If the seed placement is adjusted deeper, you must check the coulter pressure. If necessary you must increase the coulter pressure in order to assure the drilling depth.

Check the seed placement whenever changing the depth setting.

During sowing the depth guidance wheels must rest against the coulter disc and clean these. The position of the wheels to the coulter discs can be changed, if required.

Unscrew the screw (8) and pull off the wheel;Unscrew the screw (4) and change the se-quence of shims (1) accordingly; Depending on the distance remove a shim from the inside and place on the holder from outside;Mount the wheel and secure it again with the screw (8);

0

Coulter discsIn order to avoid blockage and uneven wear of the coulter discs, the coulter discs are screwed on at the front with slight pre-tension to one another.

This pre-tension will diminish due to wear and the discs will no longer have contact.In this case the discs must be renewed or re-adjusted.

Take off the cap (4), loosen the screw (5) and remove it together with the coulter disc;Remove spacers (10) and add these from outside to the screw, as required to compen-sate the wear.Fasten the coulter disc again with the screw; Make this change on both coulter discs, check pre-tension and free running;

After changes to the coulter discs check the position of the depth guidance wheels.

Press rollersWith their V-shaped arrangement the press rolls close the seed channel and press the soil against the seed.

With the adjustment lever the consolidation ef-fect of the press rollers can be matched to soil conditions and drilling depth.

Adjusting the press rollers

Adjusting the consolidation:Lift the machine;Pull the adjustment lever back out of the lock-ing gate and engage it in the new position;

Moving the lever backwards increases the consolidation.Set the spring pre-tension equally on all precision seed drill units.

Check the coulter pressure and the seed place-ment with every change to the press rollers. Any change of setting can affect the seed place-ment.

Adjusting the alignment of the press roll-ers:The press rollers must be in line with the seed furrow. The mounting can be adjusted on the drill module, if required.

Mounting of press rollers

Loosen the screws (1) of the press roller mounting on the drill module with two 3/4" spanners.Turn the eccentric bearings (2), until the press rollers are aligned centrally above the seed furrow.Retighten the loosened screws.

Changing the distance and the position of the press rollers:The press rollers can be mounted offset to each other with respect to distance and position.

Loosen the fastening screws on a press roller.For offsetting insert the press roll into another hole on the holding arm and fasten it.To change the distance you must unscrew all press rollers.Pull out the screws and fit the spacer bushings in reverse order.Fasten all press rollers.

Tightening torques see table: Tightening tor-ques.

Single seed metering unitThe metering unit consists of precision parts, which have specially been matched to one an-other and only the perfect interplay of all com-ponents ensures optimal drilling results.These components therefore require particular attention and regular maintenance and care.

Metering unit

The individual fingers pick the seed out of the provision container, clamp these under their rounded grippers and perform a slewing move-ment to transport them to the seed window.There the seed drops through the seed pipe into the seed channel.

The metering unit is suitable for sowing maize and sunflower seed. Sunflower seed requires a conversion and is therefore described sepa-rately.

The clamping plate with insert, the finger set and the adjustable brush are essential parts of the metering unit.The special belt and a specially adapted baffle plate contribute to an exact placement.

LubricationThe mechanical components of the metering unit must be lubricated by adding graphite powder to the seed.

A tea spoon of graphite power should be added per container and hopper filling. Graphite power can additionally be added at the edge of the container.Do not add the powder in the middle of the hop-per. At this place it would be consumed much to quickly, without being evenly distributed in the contents of the hopper. 500 g are sufficient for approx. 100 - 120 ha.

The seed should be mixed with graphite for initial use or after the start of the season, to ensure sufficient lubrication of the mechanical parts right at the beginning of the drilling operation.

With dressed seed graphite must be added in higher quantities, but max. 3 spoons per hopper filling should not be exceeded.

Finger setThe fi ngers are precision parts and are subjected to mechanical wear because of their permanent motion.Springs and fi ngers should be renewed as soon as the inner side of the fi ngers exceeds the wear area of 1,6 mm across the running direction.

Finger set

Clamping plateThe clamping plate carries all parts of the me-tering unit. The insert plate on the clamping plate is avail-able in two diff erent versions (observe marking) for diff erent types of seed.

Insert "A" for maize Insert "C" for sunfl ower seed.

Clamping plate with insert "A"

The insert must be checked regularly for wear, especially in the area of the brush, and needs to be replaced if required.

In order to ensure the function of the brushes these should be replaced annually or after a performance of approx. 30 - 40 ha per row.

The baffl e plate catches the grain and places it on the placement belt.Damaged baffl e plates must be renewed.

BrushesThe brushes avoid seeds being sown. In order to achieve best possible results they must be set to match the grain size before work is started.

Adjustable brushes

The brushes can be adjusted in 5 stages. By standard the brushes are set to the middle position (3).

Set the lever to the left (2 or 1):for bigger seedif not enough seed is placed

Set the lever to the right (4 or 5):for smaller seedif too many seeds are placed

Setting of brush with adjustment overview and baffl e plate

Placement beltThe belt has the function of placing the seed evenly.Due to its special shape the seed will always drop into the centre of the downpipes, which ensures optimal placement for uniform spacing of the seed.

Placement belt (observe running direction)

Wear on drive wheel

MaintenanceAfter the end of the season clean the metering unit and the area of the placement belt.Store the metering unit well protected against rodents.The belt should be replaced every 3 years or if damaged.Check the condition of metering unit and belt before the start of the season.

Adjusting the beltIf the belt rubs against the housing it needs to be realigned.

Loosen the screws for the cover and insert a large screwdriver between the projecting wheel hub and the metal cover. Then force the cover towards the outlet of the metering unit.

Sowing sunflower seedFor sowing sunflower seed the metering unit must be converted.

Conversion to "Sunflower"Install the insert plate "C";Install the finger set for sunflower seed;Set the brushes to Pos. 1;

A mixture of 80% talcum and 20% graphite is recommended for lubrication. Graphite on its own is not suitable for lubrica-tion. It results in too many errors when sowing sunflower seed.

About 20 grams of this talcum-graphite mixture are needed per hectare. This equals approx. 100 g (5 spoons) per hopper. This must be spread in along the hopper wall.

When using a new machine or with the first hopper filling at the start of the season a slightly higher amount should be added and mixed in.

SowingThe application accuracy depends on the condi-tion of the metering unit, the seed and its grain shape, the conditions of the field and the work-ing speed.

With flat grains an accuracy of 80% can be achieved, under good field conditions and large round grains an accuracy of 95% is possible.In case of wear, damage, inadequate mainte-nance or adjustment errors the accuracy can drop far below 80%.

flat seedlarge round seed

The speed of the metering unit should not ex-ceed 60 rpm for flat seed and 80 rpm for round grains.

Then tighten the nut for approx. 1/12 of a turn. Secure the nut with the crown cap and insert the cotter pin.Check the function; the metering unit must be light to turn by hand.There must be no visible play between clamp-ing plate and finger set (3).

Dismantling the metering unit:Remove the locking cotter pin with the crown lock on the clamping screw.Unscrew the nut.Remove the finger set for maize or sunflower seed.

Metering unit dismantled

Check all individual parts for signs of wear.When changing the springs on the grippers the open sides of the springs must face to-wards the retaining plate.Examine the stamped area (2) on the insert plate for signs of wear. Wear in this area will cause doubling of the seed, especially when sowing small grains. The insert plate must be checked every year and replaced when worn. During assembly take care of the lug in the area (1), it must be in line with the groove on the drive. The dowel pin on the shaft must engage in the recess on the finger retaining plate.

Maintenance:Check the coulter discs for wear, pretension and light movement. Tighten the coulter disc screws with 130 to 150 Nm.The function of and the wear on the scrap-ers must be checked at regular intervals and adjusted whenever required.

Changing the position of the coulter discs:Lift the machine and support it with appropriate means. Do not work un-der a lifted, but inadequately secured machine.

Adjust the height:Secure the machine against rolling, lift it and support it with proper jacks.Loosen the retaining screws (1) and adjust the fertiliser facility.Insert and tighten the screws.

Adjust laterally:Secure the machine against rolling, lift it and support it with proper jacks.Loosen the retaining screws (1) and add or remove spacers.Insert and tighten the screws.

Adjust all coulters equally.

Dry fertiliserIn combination with a seed wagon dry fertiliser can be placed at the same time. The fertiliser is guided through the distributor to the coulter discs. The coulter discs for dry fertiliser are laterally offset to the drilling discs. The bracket for the fertiliser facility can be ad-justed in height and laterally.

Fertiliser equipment with clod deflector

Height adjustment of fertiliser placementClod deflectorCoulter discs for fertilizer equipment

For an exact placement of fertiliser the front angle of the discs is position with slight preten-sion.The fertiliser is placed between the discs.

A scraper keeps the space between the discs free of dirt. The scraper must be checked and readjusted at regular intervals.

With wet or loose soils the pretension must not be too high, to make sure that the discs will not block up and wear of single sided.A washer can be inserted or removed, as re-quired.

This pre-tension will diminish due to wear on the coulter discs or the discs will no longer have contact. In this case the coulter discs must be re-placed.

Clod deflector

Adjusting the height:Lift the machine and support it with appropriate means. Do not work un-der a lifted, but inadequately secured machine.Caution! Danger of injuring on sharp machine parts.

Adjust the height:Secure the machine against rolling, lift it and support it with proper jacks.Remove the bolt lock, take off the bracket, pull out the bolt, reinsert it in the new position and lock it.

Adjust all clod deflectors equally.

Speed monitoringIn connection with the DrillManager the drive shafts can be monitored.The DrillManager monitors both speeds and a warning message will be issued if the minimum speed is fallen short of.

Sensor and magnet for speed monitoringDrive shaft

Both speeds must be identical. Differences in the displayed speeds can be caused by slip-page or an incorrect transmission ratio on one of the sides.

Adjusting the minimum speed:A minimum speed can be entered for both shafts. This speed should be just below the normal drive speed. This not only causes an alarm when a drive is defective, but slippage of the drive wheel will also be detected as an error.

Read the shaft speeds during normal travel and in work position and enter the alarm value ac-cordingly (see description of DrillManager).

Electric switch offThe magnetic couplings for the switch off and the tram line control are electrically controlled by the DrillManager.

The coupling must not be lubricated with oil.

Lubricating the magnetic coupling

Use only silicon spray for lubrication.Unscrew on the three screws from the coupling and spray silicon spray through the bore for about 1 second.

MaintenanceSpray the coupling with silicon spray every 50 hours;Check function and switching off;

Delete switch offThe metering units can be switched off individu-ally by hand on the drive coupling or, in com-bination with the DrillManager and the electric switch off, from the tractor

Coupling for metering drive

Check the position of the couplings on all meter-ing units before starting work.

Micro granulate facilityWith the micro granulate facility one can place fine-particle fertiliser together with the seed.The facility consists of a fertiliser hopper with metering device and mounting parts. It can also be attached later.

Drill unit with micro granulate facility

Metering unit with drive

The metering unit is driven by the coupling wheel of the single grain metering system. The metered quantity of the granulate facility therefore also depends on the transmission ratio of the single grain metering.Any change in seed quantity will also have an effect on the granulate quantity.

Seed counting systemA seed counting system for monitoring the seed placement can be installed in combination with the DrillManager. For this purpose sensors for counting the seed grains are installed in all downpipes.

Downpipe with grain counting sensor

If the nominal number of seed has fallen short off the DrillManager will report in which row too little seeds have been sown.The permissible deviation from the nominal quantity can be entered in the DrillManager.

Input and operation of equipment: see instruc-tions for DrillManager ME Maistro.

Maintenance:Depending on the amount of dust and dirt in the area of the window clean the downpipes every day with a brush.

Alarm messages caused by a too low number of sown grains can be caused by soiled seed pipes.

Adjusting the metering quantity:Due to the variety of granulates with respect to its grain size, its specific weight and the different transmission ratios for single seed metering, it is not possible to specify an adjustment table. The adjustment must be determined by calibra-tion.

For the single seed metering choose the cor-rect transmission ratio on the sprocket or, with a hydraulic drive, enter the number of grains.Remove a container from the granulate fa-cility and place it cross-wise on the cover bracket.

Fill micro granulate into the hopper and stand a suitable container to receive the calibra-tion quantity under the facility, then open the metering lever.

From the calibration table take the revolutions for 1/40 ha.

The desired number of seeds multiplied with 0,000955 results in the number of revolutions on the metering unit for the calibration quantity for 1/40 hectare.

Insert the calibration crank handle , turn anti-clockwise to calibrate the fertiliser quantity.Weigh the calibrated quantity and multiply with 40. The result is the fertiliser quantity in kilogram per hectare.

If necessary adjust the metering lever and perform further calibrations, until the correct setting is found.Set all metering levers equally and reinstall the disassembled hopper.

Check the metering device at regular intervals.

Maistro CC HopperThe hopper has a capacity of 2800 l and is cov-ered with a tarpaulin.

The tarpaulin should always be kept closed to protect the fertiliser against contamination, dust and moisture.In case of extreme development of dust, this dust can deposit in the hopper and fill up the roller flutes. This causes metering faults and unneces-sary wear inside the metering unit.

Venturi-type injectorIn the Venturi-type injector the metering unit injects the fertiliser into the air flow.For the purpose of calibration the lid on the underside is opened and the calibration bag is attached to the hooks on the housing.

In order to avoid malfunctions in the injector noz-zle or on the seed transport or the distribution, all connections and the lid must be tightly closed.

Metering unit with Venturi-type injector

Air leaks lead to metering errors.

DistributorThe distributor is mounted at the rear of the hopper. It distributes and guides the fertiliser to the coulters.

All distributor components must be leak tight. Even slightest leaks and air losses will cause uneven distribution.

The fan speed setting for fertiliser placement must be checked on all coulters before starting work and also at regular intervals when working on large areas.

The fan impeller and the protective grid have to be regularly checked for dirt deposits and cleaned.

Deposits on the protective grid restrict the air flow and thus lead to blockage in the hoses. Deposits on the fan impeller cause unbalance. The bearing will thereby be overloaded and can be damaged.

Checks and maintenanceEnsure a return flow pressure of max. 5 bar. Check the throttle valve setting.Clean the air intake grille at regular intervals to prevent a restriction in air flow and result-ing blockage. Clean any dirt or deposits from the fan blades to prevent unbalance and damage to impeller and bearing.Retighten the clamping taper on the fan shaft (see chapter Fan Flange).

FanThe hydraulic fan and the hydraulic motor for the metering drive are commonly driven by the tractor hydraulics.The tractor must be equipped with a flow-control valve to set the speed on the fan.

The hydraulic pump must deliver sufficient oil to prevent the fan speed dropping, even when the tractor speed drops or other hydraulic functions are activated.

The generated air flow conveys the fertiliser from the Venturi area to the coulters. The required air quantity depends on the type and weight of the fertiliser quantity, the working width and the working speed.A correct fan speed cannot be specified and must therefore be determined by tests in the field.

The air flow should not be too high, because this would blow the fertiliser out of the metering unit (see metering unit).It must, however, not be too weak, so that the fertiliser does not remain in the hoses and cause blockage.

To weak an air flow may also have a negative effect on the distribution.The fan speed should therefore be set as high as possible. Depending on working width a fan speed of min. 3500 rpm is recommended in order to achieve uniform transverse distribution.

Re-tightening the fan impellerThe conical clamp on the hydraulic motor fan drive can become loose due to temperature fluctuations and material deposits on the impel-ler. The impeller can creep along the drive shaft and destroy the fan.

The conical clamp should, therefore, be re-tightened after approx. 50 operating hours and checked once per year.

To do this, the fan guard must be removed.

The conical clamp fixes the impeller in position and, at the same time, clamps firmly onto the drive shaft.

Conical clamp

When re-tightening the clamping screws, atten-tion must be paid to the following.

When tightening the screws, particularly when re-assembling, the impeller creeps towards the housing in the direction of the guard. Therefore a loose flange must be aligned closer to the hydraulic motor.The clamping surfaces must be free of oil and grease.The clamping bolts must be tightened as evenly as possible in several steps. In be-tween, tap the flange lightly (plastic hammer or hammer handle) to facilitate mounting on the cone. The imperial screws in the version no. 10 - 24 4.6 must be tightened to a max. torque of 6.8 Nm. After tightening, check the impeller for free and even running.

Various cell rollers are available for the place-ment of the various seed sizes and quantities. The choice of rollers is described in the DrillMa-nager instructions.

The cell rollers are arranged according to their delivery rate per revolution.

Rollers for all types of grain and solid fer-tiliser

Cell rollers

Absolute leak tightness of components must be assured with all work on the metering unit. Leaks lead to metering errors.

When assembling the metering unit all contact faces must be sealed and distortion of the housing caused by screwing on must be avoided.

Towards the bottom the metering unit is com-pleted by the Venturi area. In the Venturi area the seed is picked up by the air flow.

During calibration the seed is taken out of the metering unit through the opening in the Venturi area.

The cover must subsequently be closed again tightly.

Changing the roller

The setting of sealing lip and the concentricity of the roller must be checked after each roller change.

Roller for fine seedsThe rollers for fine seeds consist of cell discs, spacers and drive shaft.

In order to avoid malfunction when sowing fine seed, the cell rollers are completely pre-assem-bled in the factory.

Rollers for fine seeds

Rollers fine seeds

The rollers can be assembled with one or two cell discs.The use of two cell discs on the roller doubles the delivery rate.Cell discs are available with delivery rates of 3.5 cm, 5 cm and 10 cm.

During sowing only the cell discs in the roller will rotate, the spacers are stopped from rotating by stops on the housing

Checking the sealing lipA defective sealing lip or an incorrectly assembled supporting plate causes metering errors during sowing.

The sealing lip should not be cracked or dam-aged; replace if necessary.Insert the side cover with the sealing lip into the metering housing. The seal must firmly rest on the roller.

Sealing lip

The holes for the retaining plate for the sealing lip are off set.

With all normal and fine seeds the wider side must face towards the roller. With coarse seeds like corn, beans, etc. the narrow side must face towards the roller.

Assembly note:Cell discs and spacers are assemble with shims to keep the roller assembly tight, thus ensuring that no seed will enter between cell discs and spacers.

Roller for fine seeds

The spacers are fitted with bearings. Depending on the manufacturing tolerance shims are added to avoid any friction between cell discs and spacers.

After the assembly of all parts the remaining gap to the lock washer is filled up with shims.

Finally assemble the lock washer.With the roller correctly assembled the cell discs between the spacers can just be freely turned. The parts should not rub against one another, but the clearance should be as small as possible.

When checking against a light source the gap should just be visible.

The anti-rotation locks must be turned towards the recess in the housing in order to remove and disassemble the rollers.

Assembly of roller for fine seeds

Maintenance:The function and operability of fine seed rollers must be checked every day.

There should be no gap between the cell discs. If the gap is too big, shims must be removed.The cell discs must be light turning. Dressing or similar materials must not clog cell discs or bearings.The safety clips must be in place and correctly assembled to avoid the formation of a gap.

Rape brushesThe rape brushes clean the cell discs in the roll-ers for fine seeds.

Before sowing fine seeds the rape brushes must be installed in the side cover and their function must be checked.

Rape brushes assembled

Check concentricity and fastening.Check condition and cleaning effect of brushes.Install the side cover with the brushes into the metering unit.The brushes must firmly rest against the cell discs and should rotate with the roller.

The function and cleaning effect of the rape brushes must be checked before starting sowing and at regular intervals during work.

Sticking cell discs cause metering errors during sowing. Less seed is metered.

The side cover with the rape brushes can be removed even when the seed hopper is full.Sticking cell discs can then also be cleaned in assembled condition.

The rape brushes should be disassembled when sowing normal seeds. The housing holes must be closed again.

Function testAfter installing a new roller the function and con-centricity of the new roller must be checked.

For this purpose switch on the roller as described in the section Calibration test.

The drive motor must run smoothly. No stiff points should be recognizable.

Untrue running causes inaccurate me-tering and may overload the motor.

If possible locate the stiff point.Rework damaged parts (by machining ...) or replace.Loosen the screws on the side covers for drive motor and roller bearing and realign the side covers to release tension. If the drive shaft has been bent, realign or replace it.Remove any foreign bodies that may have been jammed between roller and housing.If dust or dressing in the roller has entered between cell discs and spacers dismantle and clean the roller.

Metering unit with Venturi-type injector The metering units in machines with normal hop-per and Venturi-type injector are equipped with a V2A-cover with machined recesses.

During operation the injector nozzle is exposed to vacuum. This V2A-cover adds addition air to the air flow.

Metering unit with cover for injector nozzle

The adjustment between injector nozzle and cover works up to a max. possible seed quan-tity.

Exceeding this quantity results in a dynamic pressure at the injector nozzle. This may blow seed out through the perforated plate, which leads to a band of seed coming up towards the middle of the machine.

These grains are visible on the surface of the field before thy are covered by the packer or the harrow.

Coarse seedsFor coarse seeds (corn, beans, peas, etc.) a de-flector is installed instead of the rape brushes. This deflector prevents large seed grains from getting caught between roller and housing, being crushed and thus blocking the roller.

Deflector

Some metering units are fitted with a high sepa-rating plate.This plate must be cut off at the bottom edge of the inspection window, to accommodate the installation of the deflector.

Large seed grains partly have poor trickling characteristics and thus do not fill the roller flutes completely.In such cases talcum powder or graph-ite powder may be added to the seed.

Servicing the metering unitThe metering unit does not require any specific maintenance. In order to avoid repair related downtimes, both the metering unit and the drive motor should be cleaned and subjected to a function test after the end of the season.The bearings in the side cover in particular can be damaged or may become hard moving be-cause of dressing dust.If necessary keep bearings in stock and replace in due time.

In extreme cases the overpressure may block the seed flow in the hopper and thus cause a drill failure.

You should therefore always check the function of the pneumatic system and the placement of seed, especially with high seed quantities and working speeds.No grains should remain on the surface of the field.

If grains are blown out the fan speed must be increased (short-term up to 4000 rpm) or the working speed reduced, until the injector system works correctly again. 1

Brake systemThe Maistro CC can be equipped with a pneu-matic brake system.

This is a dual-line single-circuit brake with pres-sure regulator.

Brake diagram

Pneumatic brake hose coupling "Brake" yellowPneumatic brake hose coupling "Provision" redPipe filterTrailer brake valveAir reservoirDrain valveBrake cylinder

Hitching-upWhen hitching up connect the pneumatic brake hose coupling "Brake" (yellow) first and then the pneumatic brake hose coupling "Provision" red.

UnhitchingWhen unhitching disconnect the red pneumatic brake hose coupling first and the yellow one after.

The brake-air pressure is thereby applied to the brake cylinders and the seed wagon is perma-nently braked.

1.2.3.4.5.6.7.

In case of a pressure loss the brak-ing effect of the parked machine will drop.

The machine must therefore be parked in such a way, that it cannot roll away, even without brake.

End of the seasonIf the machine is to be parked over a longer pe-riod of time, e.g. after the end of the season, the brake should be released to prevent the brake pads from sticking to the brake drum, making restarting more difficult.

For functional safety of the valves, anti-freeze agent should be mixed to the compressed air (follow the operating instructions of the tractor manufacturer).This agent maintains the elasticity of the seals and reduces rust deposits in lines and reser-voirs.

As a preventive measure against damage caused by moisture, the pneumatic brake hose couplings can be covered with plastic lids or a plastic bag.

Maintenance:Drain the air reservoir every day during op-eration.Clean the line filter as required, but at least once every year.Readjust the brake as required; In braking position the brake lever and fork should form a 90 angle. In released position the brake lever should touch the fork at the front and the wheels must be free to turn.

Service and maintenance

Please observe the safety notes on care and maintenance.

Your machine has been designed and built to offer maximum performance, economy and operator friendliness under a vast variety of operating conditions.

Before delivery the machine was examined in the factory and by your dealer to make sure that it is in optimal condition. For trouble free operation it is very important to carry out the necessary work for care and maintenance in the recommended intervals.

CleaningPerform regular cleaning and maintenance work in order to maintain the operability of the ma-chine and to achieve optimal performance.

Do not clean electrical components or hydraulic cylinders and bearings with a high pressure cleaner or a direct water jet. Housings, screw fittings and bearings are not water proof under high pressure.

Clean the outside of the machine with wa-ter. Dismantle and clean the metering unit, check for wear.Clean seed and granulate hopper as well as downpipes with compressed air and brush.When using dry fertiliser or micro granulate clean and rinse the components thoroughly. These substances are highly aggressive and can cause corrosion.

Maintenance intervalsThe maintenance intervals are determined by many different factors. The differences in operating conditions, weather influences, driving and working speeds, dust conditions and type of soil as well as the seed, fertiliser and dressing etc. used have an effect on the maintenance intervals, but factors like the quality of lubricants and cleaning agents used on the machine also determine the period until the next maintenance task.

The specified maintenance intervals therefore only serve as a reference. In case of deviations from normal operating conditions the intervals for the necessary main-tenance tasks must be adapted accordingly.

StorageIf the machine is to be shut down for a longer period of time:

If possible store the machine under a roof.Completely empty and clean the seed and granulate hoppers.Unplug the electric control units and store these in a dry place.Protect the machine against corrosion. For spray coating use only biodegradable oils, e.g. rape seed oil.Take all load off the wheels.

Do not spray plastic parts with oil, rust remover or chain spray. These parts would become brittle and break.

Lubricating the machineThe machine should be lubricated at regular intervals and after washing with a pressure cleaner.This ensures operability and reduces repair costs and downtimes.

HygieneLubricants and mineral oil products are no threat to health, as long as they are used as instructed.Prolonged skin contact or the inhalation of va-pours should, however, be avoided.

Handling lubricantsWear gloves or use protective creams to protect against direct contact with oils.Thoroughly clean any oil off your skin by washing with warm water and soap. Do not clean your skin with petrol, diesel fuel or other solvents.Oil is toxic. If you have swallowed oil you should immediately ask for medical advice.

Keep lubricants out of the reach of children. Do not store lubricants in open and inappro-priately marked containers.Avoid skin contact with oil soaked clothes. Change soiled clothes.Do not keep oil soaked cloths in your pock-ets.Dispose of oil soaked shoes as hazardous waste.If oil has splashed into the eyes, clean out with clear water, if necessary ask for medical advice.Take up spilled oil with a suitable absorbent and dispose of.Do not fight oil fires with water, use only ap-proved and suitable extinguishing agents and wear respiratory equipment.Oil contaminated waste and old oil must be disposed of acc. to valid rules and regula-tions.

Fuels and lubricantsHydraulic systemThe hydraulic oil in the tractor mixes with the hydraulic oil in the machine.
