LINKING UP TO THE TRACTOR
1. Reverse your tractor up to the machine and connect the lower links, left hand first to the link pins
on the machine, securing with lynch pins. Adjust the right hand tractor lift arm to ensure that the
mower is level from side to side.
2. Connect the top link.
3. Stop the tractor engine and connect the P.T.O. shaft ensuring that the shaft is not too long for
the tractor. If necessary, the P.T.O. shaft may need to be shortened, (see instructions on pages
18 and 19).
4. Tighten tractor check chains to prevent sideways movement of the mower.
5. Adjust the mower height to ensure that the P.T.O. shaft is parallel with the ground.
USING THE MOWER
Before operating the machine, the following areas should be checked:-
1. Before starting up the machine, check and Lubricate all grease points.
2. Use only an agricultural tractor of horsepower within specified limits of the machine.
3. Check that the machine is properly attached to the tractor. Be sure lynch pins are used on the
mounting pins.
4. Be sure extra weights are mounted on the front of the tractor.
5. Check the oil level in the gearbox. Add as required.
6. Check that the tractor P.T.O. shaft turns freely and that it can telescope easily.
7. Check the blades. Be sure they are not damaged or broken and swing freely in their mount.
Repair or replace as required.
8. Check and tighten the blade bolts.
9. Check for entangled material in all rotating parts. Remove this material.
10. Install and secure all guards, doors and covers before starting.
11. Before connecting the P.T.O. shaft the tractor and the machine rotor must be stopped and the
key removed.
12. The P.T.O. shaft and its covers must be in good condition.

8
USING THE MOWER
13. Ensure that there are no bystanders or animals within 20 metres before starting the mower.
Keep the output of the tractor at 540 RPM.
14. Before cleaning, repairing and lubricating the machine, stop the motor and remove the key.
ADJUSTING THE HEIGHT
To get the most out of your flail mover, it should be set within the recommended height.
To save fuel and power and reduce wear and tear, the cutting height must be set correctly.
When adjusting the working height, loosen screw (1), remove screw (2) on both sides. The roller
height (see following drawing) can be adjusted by aligning the selected hole in the roller support
bracket at position 2, The lowest hole is the highest working height; put the screw (2) into the
selected hole; tighten screw (1) and screw (2).
FLAIL MOWER ADJUSTMENT
1. On a flat piece of ground, attach the Flail Mower to the Tractor using the three point linkage.
2. Use a solid adjustable top link.
3. Lower the three point linkage to its lowest position.
4. With the roller at the rear in contact with the ground, adjust the length of the top link so that the
lower edge at the side of the flail mower is parallel with the ground.
5. Rotate the blade drum by hand so that a row of blades hang vertically towards the gourd.

9
BELT ADJUSTMENT
6. Measure the clearance between the bottom of the extended blades and the ground:-
= Minimum 50mm.
= Note in rough or lumpy paddocks the clearance needs to be increased to ensure that the
blades don’t impact the ground in operation.
7. Adjust the roller height to increase or decrease the blade clearance as required.
8. Go through steps 4 to 7 until the required clearance is achieved.
When the Flail Mower has been set up with the required tolerances : Operate the Flail Mower
with tractor in low range and the P.T.O. delivering 540 RPM.
ATTENTION: All maintenance, repairing, cleaning and lubricating shall be
conducted when the tractor and motor are stopped and the
key is removed.
Remove the driving belt cover.
1. Loosen the Screw Aand B that locks the cross shaft in position and loosen the counter nut C.
2. Loosen the screws that lock the gearbox on the mounting plate D.
3. Adjust the drive belt tension by sliding the cross shaft. The correct belt tension is achieved
when the belt can be deflected by the belt thickness (about 10mm) at the centre point between
the pulleys.
4. Align the gearbox so the drive shaft is parallel with the body.
5. Use a straight edge to make sure the belt pulleys are in line and running true. If misaligned call
your dealer or service agent for technical support.

Before starting the machine, control and adjust the following items:-
= Tension of driving belts.
= Oil level of gearbox.
= All lubrication points.
= Check all bolts, nuts and screws are tight.
= Lift the mover off the ground before starting.
