FOR INSTALLATION & SERVICING OF “FARMTECH” SLASHERS
FOR ALL MODELS:
1. When attaching a FarmTech Slasher for the first time, it may be necessary to shorten the P.T.O.
drive shaft to suit the tractor. (see next page)
2. Fully slide out P.T.O. Shaft and grease male section of shaft surface – weekly.
3. Check and re-tighten the 2 clamping bolts (3/4 AF) on the Clutch to Gearbox mounting, to maintain
bolt tension following the first day’s use, then re-tension periodically.
4. Grease P.T.O. Universal Cross Bearing on a daily basis.
5. Set and adjust slip clutch on Slasher. IMPORTANT: please refer to Pg 2 on ”how to set the clutch
to work in field”.
6. Check Gearbox oil level on a weekly basis. Use 80W 90 gear oil. Remove small plug on side of
gearbox for correct level. Fill through large plug on top of gearbox. DO NOT overfill.
7. Check and grease all other lubrication points on a weekly basis, (wheel kit etc, if applicable).
8. Height of cut adjustment is made by loosening both skid retainer bolts, then reposition skid to the
desired height. Re-tighten the first bolt to maintain correct skid location – then remaining bolt. Once
skid adjustment completed, re-check tension of all adjustment bolts prior to use. It is recommended
to set the front 10-20mm lower than the rear, to give blade clearance for better cutting performance.
9. Periodically re-check all construction and mounting bolts, to ensure operational vibration has not re-
duced nut torque. Also check main rotor nut.
10. Always ensure that the Tractor used for the operation of the equipment is of the correct rating and
capacity for the safe and effective operation of the Slasher.
IMPORTANT !
Please read the following information.
Improper use and maintenance of any equipment may result in possible equipment failure, damage or in-
jury to either the operator or onlookers. All care must be taken to ensure the safe operation of all machin-
ery, if in doubt consult the equipment manual or selling dealer. Prior to operation of any machinery, read
instruction booklet carefully and carry out all operational and maintenance recommendations. Always
consider the safety and wellbeing of others and use equipment in the prescribed and proper manner.
OPERATOR INSTRUCTIONS

Cutting the PTO shaft to the correct length.
If the PTO shaft is too long it might bind when the three point hitch is lifted up. Damage might be caused
to the gearbox, clutch or the PTO of the tractor. If the PTO shaft is too long it must be cut. Both PTO
halves must be shortened by equal amounts.
1. Mount the slasher on the three-point hitch of the tractor.
2. Lift the three point hitch so that the PTO shaft of the slasher is the same height as the PTO of the trac-
tor. The slasher and tractor PTO connecting shafts should be closest to each other at that position.
3. Ensure tractor is turned off and keys removed.
4. Pull the PTO shaft apart. Connect one half of the shaft to the slasher so that the locking pin is locked
in place. Place the other end flush with the end of the tractor's PTO. Lay the ends side by side as
shown in the figure below. Mark the outer shield tube at the point 50mm short of where it needs to end.
5. Measure “X”, and then cut off this amount off both shield tubes, and both inner steel tubes. Both PTO
halves must be shortened by equal amounts.

OPERATOR MUST READ THESE INSTRUCTIONS PRIOR TO MACHINE USE.
FAILURE TO DO SO MAY RESULT IN DAMAGE TO TRACTOR OR SLASHER
SLIP CLUTCH SETTING
Initial clutch tension set up from manufacturer -
Compress all springs
Back off all nuts 2 full turns = rated torque of slip clutch
Slip clutch needs to be set if one of the following occurs -
Commencing operation of new machine
The clutch has been repaired (including replacing the friction discs)
The clutch is slipping in work (clutch getting hot, burning out friction discs, machine slowing down in work)
The clutch not slipping when the machine hits obstruction (tractor stalls, breakage may occur)
Slasher has been stored for a long period without use
HOW TO SET THE CLUTCH TO WORK IN FIELD
The setting on the clutch is dependent on many variables, the work, the size of the tractor and the size of the
Slasher. The aim is to stall the Slasher with a loose clutch and tighten it up to the exact point where it
stops slipping in normal work. If set in this way the clutch will slip if any load exceeds this point,
protecting both the machine and the tractor. The bolts, which go through the springs and hold ten-
sion on the clutch must all be set evenly, by counting the number of turns the nut has been tightened. To
commence setting of the clutch, back off the nuts to release spring tension. The clutch must be quite loose
initially to ensure it will slip. Slipping can be identified by the clutch getting very hot, and will be
quite audible to the operator. DO NOT let the clutch slip for more than 3 – 5 seconds. Run the machine for
a short distance in normal to heavy work and check if clutch is slipping. Then tighten each tension bolt up a
turn (more if the clutch was very loose) evenly and run a short distance again. Keep repeating this proce-
dure until the clutch is not slipping – it should only take a few stops. As you get to the point at which you
think it is not slipping, tighten the bolts half a turn instead of a full turn. BE AWARE you will need to adjust
the slip clutch for varying conditions (DO NOT exceed the work conditions the machine is intended for). If
the clutch is too loose it will slip, wearing out the friction discs, getting hot, and possibly damaging the clutch
pressure as well. If the clutch is too tight it will fail to protect the tractor, and if the machine hits an obstruc-
tion tractor may stall and breakages could occur.
How to free up clutch after period of storage -
The slip clutch can seize if left for long periods without use. The best way to free up a slip clutch is to loosen
all the bolts that hold the spring tension on the friction plates (so they are quite loose). Then run the machine
in normal to heavy work to slip the clutch. The clutch only needs to be slipped for approx 3-5 seconds max!
to clean up the surfaces. Alternatively, dismantle the clutch and clean it. Please refer to guidelines above to
set the clutch.
NOTE: These instructions are as set out by the manufacturer. Failure to set the clutch to protect the
transmission will void all warranty.
WARNING : OPERATOR MUST DISENGAGE PTO AND TURN OFF TRACTOR
BEFORE COMMENCING WORK ON SLASHER
CLUTCH SETUP INSTRUCTIONS

Setting up to cut:
The Farm Tech Heavy Duty Slasher comes standard with a 3 blade cutting rotor system, for increased
cutting efficiency. 3 blades give smoother cutting and better utilization of horsepower.
Set the front 20mm lower, or in other words, set the rear 20mm higher than the front to allow the retreat-
ing blade more ground clearance to stop it bogging down and trying to re-cut material.
For maximum cutting efficiency it is best to maintain rotor speed at 540 PTO rpm for clean cutting – es-
pecially for grass topping paddocks
Blades:
Check regularly to ensure they swing back correctly and are free of damage that could cause breakage.
Keep blades sharp. Use a small angle grinder to touch up the cutting edge.
Clutch setting:
The spring pressure must be set to ensure slippage can occur under excess load then take up again.
Continual slippage will burn out the clutch linings and require replacement. Inspect clutch regularly as
the clutch must work to protect gearbox and tractor PTO drive train. Reset clutch after a long period of
storage.
IMPORTANT: Refer to slip clutch setting instructions.
Chain Guards
The slasher is fitted with hanging chain guards at the front and rear to slow the discharge of grass and
other objects, that may be ejected at speed. Regularly inspect the chains and replace or repair if dam-
aged.
Oil and Grease:
When checking blades, inspect around the centre boss for oil leaks.
The Farm Tech slasher has a steel shroud located around main rotor boss to help protect the seal from
wire, grass etc causing premature failure. Keep this area clean.
Check gearbox level daily by removing small plug located approx halfway up on side of gear box.
Oil should be level with bottom of plug hole.
Do not overfill as this causes oil pressure to build up and cause oil leaks.
Daily grease trailing wheel kit pivot pins.
Oil Grade: 80W 90 gear oil.
Grease universals regularly, according to use. Long hours of use require more frequent greasing.
Grease drive shaft when disconnected from tractor, so the angle of the universal can expose the grease
nipple on the clutch end.
NEVER WORK UNDER SLASHER WITHOUT
SAFETY STANDS IN PLACE

Optional: Rear trailing wheel kit – single or twin wheel
The kit allows easier turning and better height adjustment to reduce drag.
Turn mini top link adjuster to desired height. Lock in position.
Rear wheel is solid rubber “no punctures” and long wearing life.
Grease pivot bush regularly.
Combined over run (freewheel) slip clutch
Fitted to TE20, Grey Fergie Tractors and others with single stage clutch.
Protects PTO drive line from damage.
Prevents single stage clutch tractors from being driven forward by PTO over-run.
Bizaloy hard wearing skid runners
These hard wearing strips of steel (75 or 100mm wide) can be welded to the skids for maximum wear life.
These are much harder wearing than mild steel, suitable for Contractors.
Extra heavy duty cutting discs
Extra heavy duty 2 or 3 blade cutting rotors are optional for Contractors, where cutting requirements exceed
normal working conditions.
Side Delivery – optional on some models:
To create a wind tunnel effect, a steel guard is bolted in the back half of the cutting circle. This carries the
grass around to exit out the chute. We provide a replaceable door which must be removed for side delivery
cutting. Replacing the door will give mulching, and the grass will exit from the rear.
The height of the Slasher relative to the amount of grass being cut is important, so product can escape un-
der the steel guard. In heavy cutting conditions the steel guard can be removed.
If required, steel guard can be removed for general slashing. Check the guard for damage and straighten if
required.
Deflector plate:
Depending on side delivery requirements, a deflector plate is available to deposit cut material at the re-
quired distance, ie 1-2 metres from exit to tree line. The angle of the deflector plate can be altered to
achieve the desired distance.
