CUTTING HEAD ‘VEE’ BELT ADJUSTMENT
To adjust the cutting head ‘vee’ belts the following procedure should be followed: -
Position the cutting head on the ground in a safe level location with the drive end
uppermost.
Switch off the tractor engine, remove and pocket the key.
Remove bolt securing the ‘flap-door’ of the drive end, this will release the guard flap
panel.
Open upper guard/inspection panel.
Slacken the 2 bolts holding hydraulic motor to its mounting plate.
Adjust belt tension by turning the nuts on the tensioning screw
– clockwise will tighten the belt, anti-clockwise will slacken the belt.
When the correct belt tension is achieved (refer to diagram below) the 2 adjustable nuts
on the tensioner screw must be locked tight and the 2 bolts securing the motor to the
head re-tightened to lock the whole unit into position.
Re-check tensions when all bolts have been tightened.
Close flap door and secure with bolt.
NOTE: Check belt tension on a weekly basis.
