Putting into service
PTO shaft
Separate the two half PTO shafts and connect them to
the machine's friction slip clutch 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.
To avoid serious accidents, the PTO drive
shaft guards must be properly in place and
fixed with the chains provided.
