BELT ADJUSTMENT
The drive belts are adjusted by moving the gearbox on its mounting bracket in relation to the
mower deck.
First, stop the tractor engine and remove the starting
key. Second, slacken the four holding bolts
(A) on
the base of the gearbox-mounting bracket. To tighten
belts, turn the rear adjusting nut
(B) anticlockwise,
and to slacken the belts, turn clockwise.
The belts should be free to move about 12 mm under
finger pressure. If they are too tight, there will be
undue stress on the driven parts.
When belts are adjusted correctly, lock the adjusting
nut in place, and tighten the gearbox holding bolts.
Both drive belts are tightened equally.
1. Lift the mower slightly off the ground on the hydraulics and switch off the tractor.
2. Loosen, but do not remove the fixing bolts (A) . There are two each side of the main deck.
3. Turn the adjusting screws (B) clockwise to lower the rollers, thus increasing the cutting height, or
anticlockwise to raise the rollers, thus reducing the height of cut. Ensure that all screws are
adjusted by the same amount otherwise the cut will be uneven. There is a triangular marker on
the adjuster to assist in checking for even adjustment.
4. Tighten all fixing bolts.
5. Re-adjust the top link so that then the machine is on level ground the pin is in the centre of the slot.

To adjust the cutting height when wheels are fitted. Remove
the Linch pin at the top of the wheel stem and move the
spacers from above to below the wheel arm. The more
spacers that are below the arm, the higher the cut.
There are two sizes of spacer 12.5mm and 25mm, these
correspond to the triangular markers on the roller
adjustment, which are at 25mm spacings.
