DESCRIPTION

The SD1500, HD1500 & HD1800 slashers are designed for medium to heavy duty applications such as cutting thick grass, heavy brush, saplings, scrub & small trees. These slashers use a single spindle with two free-swinging blades, mounted on a spring steel laminated blade beam. Free-swinging blades reduce the shock of impact when a stationary object is hit & the spring steel beam has additional shock absorption properties, which helps protect the gearbox from damage. Additional protection is provided by a slip clutch on the gearbox input shaft. All models are attached to the tractor using Cat.1 3 point hitches, Cat.2 hitches can be accommodated using proprietary bushes, available from most tractor dealers. Standard safety equipment includes PTO shaft covers, PTO clutch cover & front & rear discharge chain guards (for reducing ejected projectiles). NOTE All references made to right, left, front, rear, top or bottom are as viewed facing the direction of forward travel with implement properly attached to tractor.

PREPARATION FOR USE

WARNING! NEVER STAND BETWEEN TRACTOR & SLASHER WHILE TRACTOR IS BEING BACKED UP TO HITCH. ADDITIONAL TRACTOR FRONT BALLAST MAY BE NEEDED FOR STABLE OPERATION & TRANSPORT OF THE 3-POINT HITCH MOUNTED SLASHER. CONSULT YOUR

TRACTOR OPERATOR’S MANUAL FOR HITCH LIFTING & CARRYING CAPACITY. SETTING THE PTO DRIVE SHAFT LENGTH The following steps must be followed the 1st time you attach the slasher to a tractor, to ensure that the PTO shaft is compatible. An additional, illustrated “PTO BOOKLET” is supplied with the slasher; a copy can be obtained by contacting Ag-bits. 1. Attach tractor link arms to slasher – if needed refer to your tractor operator’s

manual. Do not attach PTO shaft at this time. 2. Raise & lower the slasher to determine position with shortest distance between the

tractor PTO output shaft & slasher gearbox input shaft. Shut down tractor leaving SLASHER in position of shortest distance. Securely block slasher in position.

3. Pull shaft apart. Attach outer (female) section to tractor PTO output shaft. Pull on shaft section to be sure that yoke locks into place.

4. Hold shaft sections parallel to each other to determine if too long. Each section should end approximately 75mm (3”) short of reaching the bell shaped universal joint cover on opposite section. If too long, measure 75mm (3”) back from universal joint cover & mark on opposite section – see Figure “A”.

Figure “A“ Figure “B“ 5. Do this for both sections. 6. Raise & lower the slasher to determine position with greatest distance between

PTO output shaft & gearbox input shaft. Shut down tractor leaving SLASHER in position of greatest distance. Securely block the slasher in position.

7. Hold shaft sections parallel to each other & check for minimum overlap of 1/3 of the closed shaft length. If the PTO shaft has been marked for cutting (in steps 4 & 5) overlap will be the distance between two marks. If PTO shaft has less than minimum overlap you may need to limit the linkage lifting height to prevent it from damaging the PTO shaft in use – see Figure “B”.

of 22

8. If shaft is the correct length, omit the following 3 steps & proceed to step 14.

Above: This PTO Shaft did not require cutting, it had sufficient clearance & overlap.

Figure “C” Figure “D” 9. Clamp shaft in a well padded vice to prevent damage to the plastic cover – see

Figure “C”. 10. Cut off the cover where you have marked it. 11. Using the cut off section of cover as a guide, cut shaft the same amount – see

Figure “D”. 12. Repeat steps 10 & 11 on the other shaft section. 13. Deburr the ends of the shaft tubes & clean away all metal filings. Apply multi-

purpose grease to inside of outer (female) shaft section. 14. Assemble the PTO shaft & install on tractor & slasher. Test each section by tugging,

to be sure the quick release yokes are locked into place. Make certain PTO shaft covers are in place & turn freely. IMPORTANT: Check that the PTO shaft cannot hit on the top of the slasher deck when it is raised on the hydraulic linkage.

of 22

Check the clearance here when the deck is raised – taking great care the 1st time you raise the linkage to ensure the PTO shaft does not get bent. If the shaft can strike on the deck when the linkage is lifted you must limit the lift height at the linkage control lever on the tractor, see picture below, of a typical tractor control layout, yours may be different. Consult your tractor Operator’s manual. Tractor mud guard. Linkage lift control lever. Linkage height control stop. This must be used to prevent the shaft contacting the deck. Tractor operator’s seat.

15. Adjust lower lift arm(s) to level slasher right to left using the leveling box adjuster on your tractor. Use the top link turn buckle to adjust front to back level. Refer to tractor operator's manual for instructions.

16. The PTO shaft cover is supplied with small chains for anchoring it to a stationary part of the machine, such as the lower link hitch point. Use of these chains is optional in some states of Australia; if you decide not to use the chains remove them entirely from the cover to prevent them becoming a hazard when the PTO shaft is rotating.

CUTTING HEIGHT ADJUSTMENT The cutting height may be adjusted from 30mm to 180mm by selecting 1 of the 6 setting heights available on the side skids. The slasher should be operated at the highest position which will give desired cutting results. This helps to prevent the blades from striking the ground, reducing blade wear, ejected objects & undue strain on the drive train– thick grass sometimes contains hidden surprises!

Below: Recommended initial height adjustment. Use the highest or 2nd highest setting.

OPERATING INSTRUCTIONS

GENERAL SAFETY Only qualified people should operate this machine. Operator should wear a hard hat, safety glasses & safety shoes. Always use a tractor that is fitted with a certified ROPS (Rollover Protective Structure) & seat belt. Before beginning operation, clear work area of objects that may be thrown by the slasher or that may damage it. Check for ditches, stumps, holes or other obstacles that could damage you or your tractor & slasher. Before dismounting from the tractor always turn off the engine, set parking brake, remove the key & allow SLASHER blades to come to a complete stop.

LIMITATIONS What can it cut ?

Your Ag-bits slasher is designed for cutting grass, weeds, vegetative material & small trees or saplings up to approximately 25mm (1”) diameter. -DO NOT ATTEMPT TO MOW RUBBISH! Damage & dangerous projectiles can be caused by many things, including, but not limited to, the following: rocks,

rubble, masonry (e.g. bricks or concrete), timber, sticks, steel (e.g. fencing wire, car parts), tyres, textile (e.g. sediment control barrier, builder’s plastic, baling twine). Remove or isolate such hazards before slashing is commenced. If the blades strike anything that could impact on safety or damage the slasher, stop work & deal with the hazard before recommencing. A common cause of slasher gearbox failure is loss of oil through a damaged bottom oil seal, usually caused by wire of fibrous material wound around the output shaft, above the blade carrier. Such damage is not covered by warranty; operators must routinely check & rectify this issue (see maintenance page).

Where can it be used ? Consider the proximity of roads, buildings, people etc… with consideration given to the possibility of ejected objects. Careful appraisal of the terrain & gradient of the areas which you intend to slash must be made. Consult your tractor operator’s manual for details on acceptable gradients, take into

account the extra weight that the slasher puts onto the linkage (see specifications page) & the space needed for manoeuvring. Slashers are not suitable for all situations. Be careful when in the vicinity of river banks, ravines, cliffs & steep drops. Many tractor accidents have occurred when the operator has driven too close to a hazard. It can be very difficult to judge how close to go to a hazard, particularly when there is long grass or vegetation obscuring vision. If in doubt, leave it out! It is not worth risking death or injury to get every piece of grass cut.

Climatic conditions During extremely hot, dry or windy weather it is not advisable to use a slasher in fire prone areas. All slashers throw out sparks from the high speed rotating

of 22

blades when they are working. On rare occasions this has been known to start fires. It may also be best to avoid slashing during wet weather, when the cutting performance can be affected & traction limited.

WARNING THE 3 POINT LINKAGE CAN DROP SUDDENLY DUE TO HYDRAULIC SYSTEM FAILURE. TO AVOID SERIOUS INJURY OR DEATH, SECURELY SUPPORT THE SLASHER BEFORE WORKING UNDERNEATH. AVOID PLACING HANDS, FEET OR ANY OTHER BODY PARTS BENEATH THE

SLASHER WHILE MAKING HEIGHT ADJUSTMENTS. OPERATION 1. Perform BEFORE EACH USE maintenance listed in Maintenance Section on page

12. 2. Start tractor. 3. Check the clearance of the PTO shaft over the slasher deck by raising & lowering the

linkage. If the PTO shaft can strike the deck when the slasher is raised high, a limiter must be put in place on the linkage control handle quadrant. See point 14 on pages 7 & 8.

4. With tractor at high idle speed, engage PTO drive. 5. Adjust slasher to working position with linkage control lever. Generally the slasher

will be set to slide on the skids but when turning it is necessary to raise it a little off the ground to prevent excessive side forces which can damage the slasher &/or the tractor. Always be ready to lift the slasher if it strikes an object.

6. Set tractor throttle for appropriate PTO speed (540 RPM). 7. Place tractor in gear & begin cutting. Tractor forward speed should be controlled

by gear selection, not engine speed. For maximum cutting efficiency, forward speed should allow slasher to maintain a constant, maximum blade speed. Do not exceed 8kph (5 mph). If PTO drive is disengaged due to cutting blades or tractor engine stalling, move to a “cut” area & with tractor throttle reduced to high idle restart the slasher. Always cut up & down the face of slopes, never across.

WARNINGS STAY CLEAR OF ROTATING SHAFT. DO NOT OPERATE WITHOUT PTO SHAFT COVERS IN PLACE & IN GOOD CONDITION. FAILURE TO HEED

THIS WARNING MAY RESULT IN PERSONAL INJURY OR DEATH. ROTATING SLASHER BLADES. STAND CLEAR UNTIL ALL MOTION HAS STOPPED. TO HELP AVOID AN ACCIDENTAL FALL FROM THE TRACTOR & POSSIBLE INJURY, THE TRACTOR MUST BE EQUIPPED WITH ROPS (ROLLOVER PROTECTIVE SYSTEM) & A SEAT BELT MUST BE USED BY THE OPERATOR, FOR ALL MOWING OPERATIONS.

of 22

ALL ROTARY SLASHERS HAVE THE ABILITY TO DISCHARGE OBJECTS AT HIGH SPEEDS WHICH COULD RESULT IN SERIOUS INJURY TO BYSTANDERS OR PERSONS NEARBY. THEREFORE, THIS SLASHER IS NOT TO BE OPERATED ALONG HIGHWAYS OR IN ANY AREA WHERE PEOPLE MAY BE PRESENT UNLESS ALL SIDES OF THE UNIT ARE ENCLOSED WITH RUBBER GUARDS, SAFETY CHAINS, OR OTHER EFFECTIVE SAFETY MECHANISMS THAT ARE IN GOOD REPAIR. CEASE SLASHING WHENEVER ANYONE COMES INTO THE OPERATING AREA.

TRANSPORTING When this implement is transported on road or highway, do not exceed 25kph (15 mph) when traveling. Fully raise the implement before transporting, if necessary remove the

PTO shaft to allow the slasher to be lifted to maximum height. Check statutory requirements for lights, turning signals, reflective signage etc… with your local & state traffic authorities.

WARNING WEIGHT DISTRIBUTION Before venturing onto a public road, be sure that your tractor has correct weight distribution to enable steering. Be aware that even when travelling below 25kph tractors can be seriously destabilized by bumps & irregularities in the road surface, leading to a loss of control.

MAINTENANCE

Perform scheduled maintenance as outlined below. All bolts should be torqued as recommended in the torque specifications chart, unless otherwise indicated.

of 22

THE SLASHER CAN FALL IF A HYDRAULIC SYSTEM FAILS. TO AVOID SERIOUS INJURY OR DEATH, SECURELY SUPPORT SLASHER BEFORE COMMENCING MAINTENANCE WORK.

BEFORE EACH USE

1. Check tractor tyre air pressure. Refer to tractor operator’s manual. 2. Check blades & spindle to be sure that all foreign objects such as wire, bale twine,

fibrous grass strands or steel strapping bands are removed. 3. Check blade bolts for tightness. Tighten to 329 Nm (239ft./lbs.). 4. Inspect blades for wear. Replace if necessary. Always replace both blades

together, 1 worn blade matched with 1 new blade can create an imbalance that may damage the machine.

5. Ensure the PTO shaft covers are in place & in good repair to minimize entanglement injuries to persons by rotating shafts & reduce the chance of long grass wrapping around the PTO shaft.

6. Ensure front & rear chain skirts are in good repair to minimize the hazardous discharge of high speed thrown objects.

7. Refer to lubrication guide below, follow advice for items to be lubricated “BEFORE EACH USE”.

8. During operation, listen for abnormal sounds which might indicate loose parts, damaged bearings or other damage.

AFTER EACH USE 1. Clean all loose grass & debris from machine. Replace any missing or illegible

decals. 2. Inspect SLASHER for worn or damaged components. Repair/replace before next

use. 3. Store SLASHER in a dry place.

LUBRICATION NOTE The multi-purpose grease referenced in this section is Grade 2 type grease. BEFORE EACH USE

1. Inspect the place of storage & the output shaft of the gearbox for any traces of oil leakage. If there is a leak the seal must be replaced & the oil level replenished. Replacement of the lower oil seal requires special tools & qualified trades persons.

2. PTO shaft Universal Joints - Apply multi-purpose grease with grease gun. 3. PTO shaft covers -Apply 2-3 shots of multi-purpose grease with grease gun to

plastic fitting. 4. PTO Shaft - Disconnect PTO shaft, pull the two sections apart, apply thin coat of

multipurpose grease to inside of outer (female) tube. Reassemble sections & install. Pull each section to be sure PTO shaft & covers are securely connected. Make certain PTO cover is in good condition.

5. Gearbox - Add EP85W-140 gear oil as necessary to bring oil level to check plug on side of housing.

of 22

WARNING THE 3 POINT LINKAGE CAN DROP SUDDENLY DUE TO HYDRAULIC SYSTEM FAILURE. TO AVOID SERIOUS INJURY OR DEATH, SECURELY SUPPORT THE SLASHER BEFORE WORKING UNDERNEATH.

SLIP CLUTCH OPERATIONAL CHECK After implement had been stored for 30 days or more, perform the following operational check:

1. Loosen eight nuts retaining clutch springs until springs can be turned with fingers. 2. With tractor at idle speed, engage tractor PTO drive for 2-3 seconds. Clutch should

slip without turning blades. If clutch does not slip, contact your dealer. 3. Retighten nuts by turning them until the springs are completely compressed then

unwind them 2 revolutions. SLIP CLUTCH ADJUSTMENT Your slip clutch requires periodic adjustment. Adjustment frequency depends on how regularly it has slipped during normal use. If the clutch has only slipped very rarely 9 say 2-3 times) for a small degree of rotation (less than 180o) then it will only need to be adjusted every 30 days of use. If the clutch has slipped several times on a particular job & sometimes a large degree of slipping rotation has occurred then adjustment will be needed. If during work you notice smoke coming from the clutch or the clutch is slipping too easily, adjustment is overdue. Follow step 3 above to adjust the clutch, if slipping still occurs then a ¼ (90o) tightening of each clutch bolt may help, if the clutch still slips you may need to replace the wear plates. Adjust only to provide sufficient torque to prevent slippage under normal conditions. Occasional slippage is normal for drive train protection. If satisfactory results cannot be obtained, consult your dealer. IMPORTANT Do not over tighten nut & cause spring to be fully compressed. This will prevent the clutch from slipping under high torque & could cause the shaft to fail. OVERTIGHTENING SPRING NUTS MAY CAUSE DAMAGE TO IMPLEMENT &/OR TRACTOR DUE TO INCORRECT SLIP CLUTCH TORQUE SETTING. ALWAYS FOLLOW THE PROPER ADJUSTMENT PROCEDURE. GEARBOX MAINTENANCE OIL LEVEL - The gearbox assembly on all slashers are shipped from the factory without oil. Use EP85W-140 gear oil & fill to the check plug located on the side of the gearbox. Never fill the gearbox above this level. OIL SEAL LEAKAGE - The three main causes of oil seal failure are as follows: 1. Operating SLASHER for any length of time with wire or fibrous material wrapped around the input or output shaft. 2. Loose, damaged or failed bearings. 3. Worn seals. Leaky seals should be replaced as soon as possible. To replace the seals contact your dealer, special tools & qualified trades persons are required.

COMMISSIONING CHECKLIST

Before this machine can be commissioned you must fill out the checklist in the “Ag-bits MACHINE SAFETY MANUAL, Including: Machine commissioning, Warranty Registration & Policy” – which should accompany this manual. If you do not have a copy of the safety manual contact Ag-bits for a replacement copy. In particular pay attention to the following slasher specific issues, when completing the checklist:

Check oil in gearbox (see page 13).

Check that the PTO shaft & universal joints have been greased (see page 12).

Check the PTO clutch is correctly adjusted (see page 13).

Once again check all fastenings are securely tightened with particular attention to the gearbox & blade fasteners (torque chart, see page 11).

Check the PTO length (see pages 6-8).

RUN UP TEST

With the machine attached to a tractor, perform a run up test by gradually increasing the PTO speed up to 540RPM – listen for any abnormal noises & check for abnormal vibration, do not allow use of the machine until you are satisfied that it is safe to do so.

Note Ø MOUNTING CONFIGURATION

It is preferable to mount the slasher as close as possible to the tractor by installing the linkage tower with the extended link points facing away from the tractor as shown below, in this configuration you will use the un-extended mount points which have pins in the picture below. If the front chain guards are hitting against the tractor wheels then it will be necessary to mount the linkage tower with the extended points towards the tractor & use the link point that gives clearance to the tractor wheels.
