Primary PTO shaft
The tractor PTO stub must rotate at a speed of
1000 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:
- 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’’).
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.
