2 - PRODUCT PRESENTATIONCULTIMAX is a machine that works attached to a tractor by means

of a three-point hydraulic system.It is constituted of a Tool Carrier Bar measuring 4.20 m, 6.00 m and

6.80 m in length with a three-point interlocking system, which can be suppliedin the following versions:

CULTIVATOR, FERTILIZER DISTRIBUTOR CULTIVATOR ANDFERTILIZER DISTRIBUTOR.

As CULTIVATOR, its active elements are hoes (of different sizes, atyour choice, according to the culture and infestation level), fixed onVIBRATORY RODS made of special steel, which print a HIGH FREQUENCYvibratory motion on the hoes, thus UNEARTHING THE WEEDS ANDSHAKING THE ROOTS, LOOSENING THE EARTH AND EXPOSING THEMTO SUNLIGHT, ALLOWING FOR THEIR ELIMINATION.

For these active elements to perform their function properly,PANTOGRAPHIC MODULES are fixed, which fully follow the soil's profile,ensuring the same work depth throughout the land's extension.

In addition to the function of controlling weeds, your CULTIMAX canalso be used in breaking the superficial crust of the soil and thus prevent theevaporation of water. In a "VERANICO" condition, quite common and harmfulabove all in the first days of the culture, you can pass the CULTIMAX adjustedto the least depth possible. On breaking the ground's superficial crust, itprevents the evaporation of water and its culture will immediately present amuch better aspect.

It can be supplied in modules of 3 or 5 furrowing hoes, for the cultivationof 3,4,5,6,7,8,9 and 10 lines, with the Tool Carrier Bar (TCB) measuring4.20m and for 5 to 12 lines, with a TCB of 6.00m or 6.80 m.

The distribution of fertilizer is made by means of worm thread system,and can be deposited on the soil by conductor tubes, or incorporated (inconventional or direct planting) by means of mismatched double disks'furrowers. The system used in CULTIMAX allows lateral or double-lateralfertilizer distribution.

As CULTIVATOR FERTILIZER DISTRIBUTOR, it can be supplied forlateral or double-lateral fertilizer distribution, with modules of 3 or 5 hoes,and with 2 to 8 fertilizer deposits for the cultivation and fertilizer distributionof 3 to 8 lines according to you needs.

As a FERTILIZER DISTRIBUTOR, it can be equally supplied forfertilizer distribution. Instructions Manual for Lateral or bi-lateral cultimaxwith conductor system for the depositing of fertilizer on the soil, or systemof mismatched double disk furrowers for the incorporation of the fertilizerinto the soil in both direct planting and conventional planting, with 2 to 8fertilizer tanks for fertilizer distribution of 3 to 8 lines, according to yourneeds.

6 - PRODUCT COMPOSITIONJUMIL'S CULTIMAX is supplied in the models CULTIVATOR,

FERTILIZER DISTRIBUTOR CULTIVATOR OR FERTILIZERDISTRIBUTOR, with the cultivation options of 3 to 12 lines. Upon acquiringyour CULTIMAX, attentively verify that all components accompany theequipment.

7 - PRODUCT ASSEMBLYJUMIL'S CULTIMAX already comes assembled from the factory and

only requires its preparation for use.

The traction wheel is comprised of the traction wheel, with gears andchain, and a simple wheel for sustaining and supporting the equipment.

When assembling, consider the spacing between the lines in order tohave the wheels remain in a position between the lines, and if necessary,allowing them to be put in front of the tool carrier bar.

If the equipment has more than eight tanks, we recommend the useof two traction wheels with two gear sticks,thus dividing the equipment in two, each halfbeing actuated by a traction wheel.

Installation is quite simple, installedon the tool carrier bar by means of claspsfastened by the respective nuts, as well asthe sustaining wheel.

The gearshift stick should be installedin such a way to receive the motiontransmitted by the drive wheel, thus allowingfor its change in position.

8 - PREPARATION FOR USEBefore beginning the job, carry out a general adjustment of your

equipment, especially in the fastening bolts of the furrower module claws.Check the pins and keys also.

Check if there any object inside the tanks and remove them to preventdamaging the distributor sets. Lubricate the product according to theinstructions.

ATTENTIONBefore placing the

CULTIMAX into operation, removethe plug "a" from the reducer, andreplace with the vented plug thatcomes with the equipment (Fig.07).

8.1.2 - Actuation Wheel

The CULTIMAX fertilizer distributorcan also be actuated by an actuation wheelsystem substituting the cardan/reducer typetransmission. Actuation by means of thewheel has the advantage of keeping constantfertilizer output regardless of the tractor'sspeed and engine regime, which is not thecase in the other system.

Actuation is made by means of achain "d" (Fig. 08) that transmits the motionof the actuation wheel to the equipment'sgearbox.

8.2 - Preparing The Tractor

Before starting to work with the equipment, proceed with the preparationof the tractor. Usually, the tractor is equipped with a set of wheel adequatefor cultivation, with high wheel and narrower tires in order not to damage theculture during work. As the compacting rate of the narrower tire is higher,and as there is no need to obtain good traction, the rear tires do not requireballasts, and the water and /or weights are removed from the rear wheels.

8.2.1 - Ballasting The Tractor's Front

Working with an implement installed in the three-point system oftractor, as is Cultimax's case, it is absolutely natural that the tractor's front,in given circumstances, tends to lift off the ground. To compensate thistendency, the tractor manufacturers place a support on the front to supportweights which are used in balancing the tractor, and should be removedwhen not required. A practical way of determining the minimum quantity ofthe weights to balance the tractor is as follows:

On scale, weight only the front wheels of the tractor without interlockingthe implement. After interlocking the implement, put it in transport position(fully lifted by the hydraulic system) and weigh the front wheels again.

Install the necessary weights to obtain at least over half of the initialweight.

8.1.3 - Tire Pressure

For a lasting service life, the tires should contain the correct pressure.Lack or excess of pressure lead to premature tire wear. Check if the tires ofthe Cultimax are with their pressure within the range of 30 pounds/inch.

Much pressure Little pressure Correct pressure


16

8.2.2 - Gauge Adjustment

In order to pass with the tractor's wheel between the lines, allowingfor a perfect job, it is necessary, as it is during the planting, to adjust it'swheel gauge. Therefore, proceed as follows:

Simple (4x2) and double (4x4) traction tractors: Install the tires (centerto trail center) at a distance equivalent to twice the spacing between thelines. Although the 4x4 tractor is not recommended for planting, many times,however, the farmer only has this type of tractor for use.

8.2.3 - Coupling The Machine To The Tractor

Coupling the machine into the tractor's 3-point hydraulic lifting system,starting from the right side arm. If too far, maneuver the third-point arm,shortening or extending it to align the machine with this arm. In case thereis a different in height, the tractor's arm has a mechanisms that allowscompensation. Interlock the cardan shaft, being careful to interlock the spidersto each other, putting the respective locks which should be symmetrical.

ATTENTIONBefore coupling the cardan between the tractor and the

machine, make the necessary adjustments on the cardan.

Use the weights supplied with the tractor or purchase them from theauthorized dealer, avoiding as much as possible their use on the front wheels.

Caution: placing frontal weights does not always keep the tractorproperly balanced, especially if driven too fast on an irregular land with theequipment lifted. Be prudent and drive slowly, especially under suchconditions.

17


8.2.4 - Adjusting the cardan to the tractor and the machineFor the proper functioning of the cardan, we recommend following the

instructions below before starting the job:1- With the machine installed on the tractor, detach the shaft from the

cardan pipe. By means of the respective pressure buttons, fasten thecorresponding ends on the tractor and the machine.

2- Overlap one on the other and mark each to delimit the excess tobe cutoff. In addition to this marking, consider a 40 mm slack (Fig. 09). Donot cut yet.

3- Raise and lower the machine with the cardan disarmed (pipe andshaft overlapped) through the tractor's hydraulic system, verifying if themarked slack - 40mm does not exceed the limit established, causinginterference on the fork bodies, i.e. it should maintain a slack in any workingposition of the machine (Fig. 10).

Fig.09

Fig.10

4- After defining the spots to cut, shorten the internal and externalprotective pipes equally. Shorten the internal and external sliding profiles bythe same length as of the protective pipes. Remove all tips and rough edgesand grease the sliding profiles.

40mm40 mm

For the installation of the cardan (pipe and sliding profile), observethat the internal and external forks always remain aligned in the same plan.Otherwise, the cardan will be subjected to vibration, leading to prematurewear of the crosspieces

ATTENTIONThe size of the cardan should be verified and/or adjusted

if required, whenever the tractor model and/or brand ischanged. Failure to observe this may damage the machine and/or cardan.

8.2.5 - Cardan assembly

19


8.3 - Leveling The Machine

For a perfect operation of the CULTIMAX, it should be level in bothdirections. To achieve this, use the third point arm and the right side armcrank of the tractor.

After leveling, if possible, on a shed or flat land, adjust the stabilizersin order to have the equipment stay with the least slack possible.

To do this, lift the equipment to the highest position of the hydraulicsystem and adjust the stabilizers equally, while the equipment is centralized.

By adjusting while the equipment is on the floors and the stabilizersstretched, when lifting the hydraulic system for transport, you run the risk ofdamaging the stabilizers.

9 - ADJUSTMENTS

The fertilizer output is made bymeans of individual conducting wormthreads.

The different dosages areobtained by means of the change inthe positioning of the chain betweenthe reducer "a" and the drive shaft"b" (Fig. 11).

In case an outlet is not used,close the fertilizer distributor with aplug "a" (Fig. 12). To put the plug,remove the worm threat "b" and the*deflector "c" (Fig. 12).

*Deflector - present only inequipment manufactured until Dec/1997.

The indicative table that followswas developed for an estimate, andgives an idea of how to beginadjustment, seen that there arevariations in terms of brands, density

and humidity of the fertilizer, tractor skidding and cultivation operational speed.The fertilizer distribution table indicates the ratio of gears to be used,

as well as the quantity of fertilizer to be distributed according to the culture'sspacing.

The fertilizer distribution table was defined considering that work isdone at 5 km/h.

To obtain a good regulation for the distribution of the fertilizer, proceedas follows:

1- Run 50 meters exactly at 540 RPM on the TDP shaft.2- Record the time taken. Dividing 180 by the number of seconds you

will obtain the speed in km/hour. Set it to obtain 5km/hour, if it spends 36seconds to run 50 meters, it goes at a speed of 5 km/hour.

3- With the tractor parked, set it for the desired fertilizer quantity, putin the outlets of the hoses a recipient to collect the fertilizer;

4- Connect the shaft of the power socket. When the fertilizer drop isnormalized, collect the fertilizer the fallen fertilizer during the same recordedtime. In theory, it means that you covered the same space;

5 - Next, weigh the collected fertilizer;6 - Check on the fertilizer distribution table if the quantity of fertilizer

is the one recommended according to the spacing of the culture.

9.3.1 - Calculation For Fertilizer Distribution

To calculate fertilizer distribution:1- Check the spacing between the lines:2- Define the quantity of fertilizer to be distributed per hectare;3- Calculate according to the example below:

Formula data:E - Spacing between linesQ - Quantity of fertilizer to be distributedA - Area to be fertilizedD - Distance of 50 meters for the testX - Fertilizer grams in 50 meters

Fórmula:

X = E x Q x D A

9.3 - Practical Example Of Fertilizer Distribution Calculation


24

ATTENTIONThe table presented in the second column, the quantity of

fertilizer in grams in 50 meters per line, considering only one fertilizeroutput per line. When making the bi-lateral fertilization, i.e., two sidesof the plant, the values in grams in 50 meters per line and theremaining values of the kg/hectare table should be divided in 2 (two),as two fertilize outlets are used.

9.3.2- How To Use The Fertilizer Distribution Table

FOR LATERAL FERTILIZING (Example)For the distribution of 200 kg/ha in the spacing of 85 cm, we recommend

the use of 19-tooth motor gears, and the driven gear of 15 teeth (Fig. 15),and work with the tractor at a speed of 5 km/h, with the rotation of 540 RPMat TDP.

FOR BILATERAL FERTILIZATION (Example).For the distribution of 200 kg/ha in the spacing of 85 cm, we recommend

the use of 17-tooth motor gears, and the driven gear of 27 teeth (Fig. 15),and work with the tractor at a speed of 5 km/h, with the rotation of 540 RPMat TDP.

Example: A culture with the spacings between lines of 90 cm (900mm) to distribute 111 kg of ammonium sulfate in an area to be fertilized of 1hectare (10,000 m2), with a test distance of 50 meters.

X = 900 x 111 x 50 10,000

X = 99,900 x 50 10,000

X = 9.90 x 50

X = 499,50 fertilizer grams in 50 meters

X= 499.50 fertilizer grams in 50 meters

9.5 - Adjustment of Furrowing HoesThe adjustment of the distances of the furrowing hoes according to

the planting line can be done by means of the support tube "a" or the furrowerarms "b" (Fig. 14).

To move the support tube "a" to the right or to the left, loosen theclamps "c" and move the tube until the desired distance. To adjust thevibrator arm, loosen the bolt and clamp "d" (Fig. 14).

ATTENTIONWhen refastening the support tubes of the furrower arm, make

sure to tighten the nuts of clamps "c" equally to prevent any of thearms staying higher than the other (Fig. 14).

ATTENTIONWhen cultivating a plant with a given size, see that the

adjustment tube of the furrower arms do not touch the plants anddamage them (Fig. 15).

ATTENTIONUse the hoes of the cut wing next to the plant

27


9.6 - Depth Control Adjustment

The depth control of thecultivation is made individually bymeans of a depth control systemcomposed of a controller bar and rodthat is firmly supported on the floor,allowing for cultivation at thedetermined and uniform height, evenwith ground undulations.

Adjustment is made by meansof a lever "a" (Fig.15) over the courseof the indicative scale (Fig. 15)observing the individual adjustment ofall furrower modules, ensuring theuniformity of the depth.

The scale indicates from 1 in 1 cm the depth desired, or according tothe cultivation.

There are three- holes in the module of the board "a" (Fig. 15) used toallow for the adjustment with the adjustment tube of the compactor wheel,allowing the adjustment of 1 in 1 centimeter.

For the adjustment and alignment of the fertilizer distributor drive chainits necessary to obey the following:

1 - Check on the fertilizer distribution table, the quantity of fertilizer tobe distributed and the gear ratio tobe used;

2- Loosen the bushings of thefastening bolts "a" that fasten thegears and align the motor and drivengears (Fig. 16);

3- Put the stretcher in thecorrect position according to thetables

4 - Align the motor and drivengears for the chain to work freely;

5- Loosen the bolts of thefastening bushings "a" that fasten the motor and driven gears (Fig.16)

10 - MAINTENANCE

We suggest some care with the maintenance, which will allow for alonger service life of the equipment and better performance.

Periodically, the equipment should require some repair and the itemsbelow are of extreme importance for the perfect, interruption-free operation.

10.1 - Cleaning The Fertilizer Tanks

After covering, do not leaving thefertilizer inside the tank. Werecommend totally emptying the tank,scarping the fertilizer off the wormthread and wash it with running water.

To clean it, loosen the pegs "a",remove the drive shaft connectionbushing "b" to free the tank and thentilt the tank, facilitating cleaning (Fig.19)

aFig.19

ATTENTIONBy the end of each workday, remove the rest of the fertilizer

from the tanks and carefully clean the equipment. Retighten the boltsperiodically.


40

10.2 - General Cleaning Of The Cultimax

When storing your CULTIMAX until the next planting year, give it ageneral cleaning. Remove the fertilizer conductors from the tanks, washthem and keep them.

Check if all moving parts do not present wear, and replace, leavingthe CULTIMAX ready for the next job. Retouch the paint, especially partsthat come in contact with the fertilizer.

Protect the plastic tanks and spray the CULTIMAX with conservingoil, making sure not to use burnt oil.

Having carried out all the maintenance repairs, store the CULTIMAXin an adequate place, away from intemperate weather. Use the support feetto keep it standing and not overload the machine on the furrower arms.

41


11.1 - Lubrication Objectives

The running efficiency of any machine relies much on the suitablelubrication and it is therefore fundamental to ensure proper and qualitylubrication is made to prevent reduction in the equipment's efficiency, leadingalso to premature wear of parts.

In heavy duty conditions, we recommend reducing the lubricationintervals indicated in the Figures.

ATTENTIONBefore beginning lubrication, clean the grease fittings and

replace the damaged ones.

11.2 - Lubrication Symbols

The Cultimax line was developed and tested with the utmost care andas such, it is ready to perform a perfect service in order to completely satisfyyour needs.

Anything that is out of its perfect running is an incident caused by acircumstance unrelated to the machine. With the intention of preventingsuch circumstances, we have listed below some of the commonest incidents,their causes and how to solve them. However, if after having verified andperformed the rectifications accordingly your equipment fails to work perfectly,contact your dealer or Jumil through the Customer Technical AssistanceCenter.1 - The cultivator is moving too much earth.

a) The hoes are penetrating too deeply.Check the arm of the third point; it is probably too short.Solution: Put the cultivator on a plane place and extend the arm until

the Cultimax is leveled. In this case, it probably just needs to extend thearm.

Check the depth limiter wheels. it may be that they are adjusted fora deeper depth than the one recommended.

Solution: Adjust the depth accordingly.b) The hoes are penetrating deeper on one side.Check the hydraulic arm on the right side of the tractor: its length is

probably different from the left arm's.Solution: As the left arm does not have a system to alter its height, it

is common that the right arm stay with a different height. Actuate over thesystem and extend or shorten2 - The spaces to which the active bodies of the Cultimax are adjusteddo not coincide with the spaces of the culture.

Ensure that the planter was correctly adjusted for the desired spacing.Possibly, the spacing is different, causing this maladjustment.

Solution: Subject the spacing of the Cultimax to that of the planter.It is possible that it is "entering" a different planting sequence and

although the line marker has been used, whose function is precisely toprevent different spacing between the lines, such fact may occur by failureon the part of the operator during planting.

Solution: Enter into the same planting sequence and train the operator.

12 – INCIDENTS AND TROUBLESHOOTING


46

3 - The hoes sometimes touch the plants, at times on one side, at timeson the other.

The stretchers of the hydraulic arms are probably too loose, allowingthis "play" of the Cultimax.

Solution: Equally adjust the stretchers with the equipment raised bythe hydraulic system. In case you proceed with this adjustment of the machineon he ground, you will run the risk of damaging the stretchers by actuatingthe lifting through the hydraulic system.

The operator cannot keep the tractor's steering firm. Probably, thetractor's front is too light and steering becomes difficult.

Solution: Put the appropriate weights on the front and on the wheelsof the tractor.4 - The arms are not "shaking" the weeds, which run the risk of notdying.

You are probably moving too slow, which makes the vibratory actionof the springs difficult.

Solution: Increase the speed until you obtain the vibratory effect. Theinfestation is probably too large, having gone past the suitable period formechanical cultivation.

Solution: You may carry out the mechanical cultivation but accordingto the weather (rainy), you may run the risk of the weeds not dying.

You may be working with the hoes in too deep.Solution: Reduce the depth, actuating on the depth control wheels.
