Primary PTO shaft
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. As a safety measure, a clearance (L) of
at least 10 mm (0.39’’) must be maintained.
If this is not the case:
Never operate the PTO shaft at an angle X exceeding
30°.
Make sure that the PTO shaft is correctly
adjusted, to avoid premature wear and tear.
Follow instructions given in the operator's
manual delivered with the PTO.
