6.1.4 Primary PTO shaft
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:
• Check the maximum overlap when the machine
is in transport 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.
Before using the machine for the first time:
- Grease the transmission .
Check overlap of the u-joint drive shaft and
adjust length if necessary to avoid any
premature wear.
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.
