.
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:
- 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
25 mm (1’’) must be maintained.
- When the PTO shaft is in its maximum extended
position, the tube overlap must be more than
250 mm (10’’).
If this is not the case:
• Mark length (H) to cut when the transmission is the
maximum overlap position.
• Shorten the guard tubes and the transmission tubes
by the same length.
• Bevel and clean the tubes.
• Grease the inside of the outer tube.
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.
