OPERATION WITH THE P.T.O.
SHAFT
1.
When operating with the P.T.O.
shafts, be aware of the proper attach-
ment of all the guards.
2.
As soon as the operation with the
P.T.O. shaft is over, re-attach the P.T.O.
shaft cover.
3.
For coupling and uncoupling the pro-
peller shaft of the aggregated machine
to / from the tractor, put the lever of the
shaft dependent and independent
speeds to the neutral – N – position!
4.
For carrying out any repairs or clean-
ing of the aggregated machine compo-
nents driven by the P.T.O. shaft, stop
the engine, uncouple the P.T.O. shaft
coupling, and put the lever of the shaft
dependent and independent speeds to
the neutral – N - position!
CONTROL OF THE FRONT AND REAR
P.T.O. SHAFTS
Coupling (at minimum 1 500-r.p.m. engine
speed) and uncoupling of the P.T.O. shaft
couplings is electro-hydraulic..
It performed with a switch installed at the
rear R.H. cab post. Switches are
equipped with mechanical lock (1)
avoiding the accidental turning on. Move
the lock downwards when turning on.
P - Switch controllin
the rear P.T.O.
shaft electromagnetic valve.
With turning ON both switches, the two
P.T.O. shafts are put into operation (front
and rear ones).
Switching the P.T.O. shafts ON is sig-
naled with the lighting symbol on the
switch.
REAR P.T.O. SHAFT – SHIFTING OF
DEPENDENT AND INDEPENDENT
SPEEDS
PTO -
Independent P.T.O. shaft
speed shifted
N -
Neutral position
To be used for easier cou-
pling of the agricultural ma-
chine propeller shaft.
The tail of the rear P.T.O
shaft is free to move.
PTO
synchro -
Dependent P.T.O. shaft
speed shifted (the speed
depending on the tractor
travel speed)
