CUTTING HEAD ‘VEE’ BELT REPLACEMENT
To replace the cutting head ‘vee’ belts the following procedure should be followed: -

Hydraulically position cutting head to stand vertically on the ground with the drive end
uppermost -
this should be done on a firm and level location to ensure the cutting head
is steady and safe in this position.

Stop tractor engine, remove and pocket the key.

Slacken off the motor mounting bolts and nuts on the threaded adjuster arm to release
the belt tension.

Undo completely, and remove, the 6 bolts that attach the main cover plate to the head.

Undo, and remove, the 6 M12 x 20 setscrews that hold the bearing housing to the cover
plate.

Remove the cover plate from its bolted position.

The drive belts can now be removed from around the pair of ‘vee’ pulleys.

New belts can now be fitted – position each belt in the respective ‘vee’s’ on both the
driven and the driver pulleys.

Replace the main cover plate assembly over the drive belt aperture.

Replace the 6 M12 x 20 setscrews through the plate and into the bearing housing.
Ensure all 6 screws are aligned correctly and tightened sufficient only to hold the
bearing housing in place.
DO NOT TIGHTEN FULLY.

Replace all of the M12 x 80 bolts through the cover panel from the panel side –
ensuring first that the holes align –
and place the ‘nyloc’ stiffnuts onto each bolt.

With all mounting bolts of both bearing to panel, and panel to head now in position all
12 bolts should be tightened until fully dead tight.

Belts should now be adjusted to the correct tension as per the diagram below – refer to
belt adjustment section for details.

When belts have been tensioned correctly and all covers replaced, the machine is ready
for start up.
