6.1.4 Primary PTO shaft
- Make sure that the PTO shaft is correctly
adjusted, to avoid premature wear and tear.
- Check overlap of the u-joint drive shaft and
adjust length if necessary to avoid any
premature wear
The direction of rotation is shown on a decal.
- Separate the two half PTO shafts and connect
them to the machine's input shaft and to the tractor
PTO stub.
- Check the length of the PTO shaft:
• Fully raise the machine:
When the PTO shaft is in its maximum extended
position, the tube overlap must be more than:
220 mm (8’6’’).
• Lower the machine in order to place PTO shaft in
horizontal position:
When the PTO shaft is in its maximum overlap
position (retracted), tubes should not butt against the
yokes. Keep a minimum safety travel L: 25 mm (1’’).
