This mower is driven with a maximum
power take-off shaft speed of
540 rpm
.
Under no circumstances may it be
operated with a higher power take-off
shaft speed.
The PTO shaft must only be fitted
or removed when the power take-off
shaft and the engine are turned off and
the ignition key has been removed!
2.2 P.T.O. Shaft
The PTO shaft is slid onto the gearbox input shaft with
the friction clutch towards the disc mower, and it is
rested on the support bracket (1). The safety chains
must never be used to hold the PTO shaft. Make sure
that the locking device of the PTO shaft has snapped
into position.
Adapting the PTO Shaft
In order to adapt the PTO shaft, the two halves of the
shaft (1) and (2) should be held next to each other in
the shortest operating position to check the overlap of
the section tubes. If the overlap is too great, the section
tubes and protecting tubes must be shortened so that
they can move freely in any operating position and do
not knock each other. The exact procedure for
shortening the PTO shaft can be found in the operating
instructions from the PTO shaft manufacturer, which
are supplied with the PTO shaft.
Check the swivel space and the free
movement space of the PTO shaft. If the
PTO shaft touches the tractor or the
attachment, this can cause damage.
Special equipment
Auxiliary gearbox for 1000 rpm power take-off shaft
Operation with a power take-off shaft speed of
1000 rpm at the tractor requires the fitting of an
auxiliary gearbox (1) on the mower unit.
- The retaining chain should be inserted
to prevent the PTO shaft guard from
rotating with the shaft.
- The chain should be inserted in such a
way that the PTO shaft has sufficient
freedom of movement in all operating
positions.
