„ PTO shaft
The tractor PTO stub must rotate at a speed of 540 min
-1
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:
- Check the maximum overlap when the machine is in
work position and the tractor turned to the direction
which provides maximum overlap.
- 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.
Check that there is still a minimum overlap of
250 mm (10’’) when the machine is in working
position and the tractor in line with the machine.
