SHORTENING THE PTO SHAFT
The use of too long a PTO
shaft with a 3-point hitch
could damage the chipper’s
bearings or the tractor’s
PTO shaft. Both halves of
the PTO shaft must be shor-
tened equally.
Recommended PTO shafts:
• Bondioli & Pavesi G8 + RA2 overrunning
clutch on the chipper side
• Walterscheid W 2500 + F5/2L overrunning
clutch on the chipper side
If the tractor features a PTO brake, an overrun-
ning clutch must be used.
1. Mount the machine on the tractor’s 3-point
hitch.
2. Lift the machine with the hitch so that the
distance between the splined shafts is at its
shortest. Fig. 8.
3. First, cut the thicker shield to the correct
length (1). Remember the 20-40 mm cle-
arance. Then, cut a similar length from the
profile tube (2). Shorten the other PTO
shaft half similarly. Remove burrs using a
file.
4. Insert the inner tube in the outer tube and
carefully move the machine up and down.
Ensure that the shaft was shortened suf-
ficiently. Check that the shaft has a 20-40
mm clearance. In addition, move the ma-
chine sideways and ensure that the PTO
shaft does not bottom.
Measure distance A when the distance between
the splined shafts is at its shortest.
