6.2.8 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:
• When the PTO shaft is in its maximum overlap
position (retracted), tubes should not butt against
the yokes. There must still be a minimum safety
travel (L) of 25 mm (1’’).
•
When extended to the maximum, the tube
overlap must not be below 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°.
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.
To avoid serious accidents, the PTO drive
shaft guards must be properly in place and
fixed with the chains provided.
