JOINT COUPLING — PTO SHAFT
FPM
Boljevac
It is extremely important to properly adjust the
PTO shaft for attaching the mower to the tractor.
Never allow the universal joints to get jammed
when the machine is raised in the topmost or
lowered in the bottommost position. The PTO
shaft has a star ratchet clutch. Make sure to install
the star ratchet clutch on the mower side to
enable operation of the mower.
If you determine that the PTO shaft is longer and
therefore impossible to attach to the tractor, it
must be cut to length. The following pictures show
how to cut the PTO shaft to length.
1.- Attach one PTO shaft half to the tractor and to
the, mower while keeping the other halves near
each other.
Keep adjusting the tractor and mower position
until a 10 mm length is identified, and
mark this length on the guard, see Fig. 25.
2.- Cut the guard, see Fig. 26.
3.- Cut the section tube, Fig. 27. No further
modifications to the guard or the section tube
are allowed.
NOTICE: FAILURE TO OBSERVE THE
BASIC REQUIREMENTS FOR THE
PTO SHAFT OPERATION MAY LEAD
TO BREAKAGE OF THE PTO SHAFT
OR DAMAGE TO THE ROTARY MOWER.
4:- Remove any sharp edges, Figure 28.
5:- Clean and apply grease, Figure 29. Attach
the PTO shaft
pipes to complete the operation.
6.- Never remove or allow PTO shaft guard to
rotate. Hang the guard chain on
the PTO shaft guard, Fig. 30.
7.- The PTO shaft may not operate
under a too large angle (max. 10 deg.)
