REAR POWER TAKE-OFF SHAFT (PTO)
PTO of PRONAR tractors may drive hitched cooperating machines with revolution speeds:
- independently (of travel speed), standardised: 540/1000 or 420/750 rpm
- dependent (on travel speed). Number of revolutions per metre of road is fixed, independently of
which gear is engaged.
ATTENTION: Before connecting machine powered with PTO one must check that the
PTO rotation speed of the tractor corresponds to the required speed of the machine
shaft.
ENGAGING PTO DRIVE
ATTENTION: To eliminate dynamic loading in PTO drive transfer system before
engaging PTO shaft drive, reduce engine RPM to 900 rpm. After engaging PTO drive,
increase RPM required level. Before disengaging PTO drive also reduce engine RPM. It
is particularly important in combination with machines with a great moment of inertia.
Such machines should be equipped with a one-way clutch.
Failure to comply with the above instructions may lead to accelerated wear of PTO drive transfer
system components and, as a consequence, increase the frequency of necessary maintenance
adjustment or part replacement.
In PRONAR tractors, the PTO drive is connected with the switch placed on the console on the
right side of the seat (Figure 4-29) or outside the tractor with button placed on the rear right mudguard
(Figure 4-30).
ATTENTION: The operation of engaging and disengaging PTO is conducted only with
the engine running.
In order to engage PTO, first press the black button in the middle of the yellow mushroom switch,
and next pull the yellow part upwards (as shown on pictogram).
In order to disengage PTO press PTO switch to the base.
ATTENTION: Before raising machines (implements) suspended on three-point linkage,
driven by the tractor's PTO, or making turns, disengage the PTO drive.
ATTENTION: AT SHUTTING DOWN THE ENGINE - PTO DISENGAGES AUTOMATICALLY
