Drive Of Farming Machines; Work With Pto Shaft; Front And Rear Pto Shaft Control - Zetor Proxima GP Series Operator's Manual

Work with PTO shaft

Before attaching of an implement, driven by means of the tractor PTO shaft, check the speed
compatibility of both, it means tractor PTO shaft and implement driven shaft (540 rpm or 1,000 rpm).
Different PTO speed values may cause serious damages and injuries.
1. When working with the output shaft pay attention to proper fixing of all covers.
2. After completion of work install always the output shaft cover.
3. Connect and disconnect the articulated shaft of the coupled mechanism to the rear output shaft of
the tractor always when the engine is stopped, output shaft disengaged and lever of shifting of
dependent and independent rpm of the output shaft in position 'N' - neutral!
4. Connect and disconnect the articulated shaft of the coupled mechanism to the front output shaft
of the tractor always when the engine is stopped and output shaft disengaged!
5. Perform any repairs or cleaning of parts of the coupled mechanisms driven by the output shaft
only when the engine is stopped, output shaft disengaged and lever of shifting of dependent and
independent rpm of the output shaft in position 'N' - neutral.

Front and rear PTO shaft control

Engagement (with minimum engine revolutions of 1,500 min
switches:
(A) standard tractor - placed on the right pillar of the cab.
(B) tractor equipped with electrohydraulics EHR - placed on the external hydraulic circuit control panel
The switches are equipped with mechanical catches (3) against undesired switch. When switching the
switch, press the catch (3) in the direction of the arrow.
(1) The switch controls the rear PTO shaft
(2) The switch controls the front PTO shaft
Both PTO shafts are set in motion (front and rear) by switching both switches. The engagement of PTO
shafts is signalized by a lit symbol on the switch.
Rear output shaft - shifting of dependent and independent speed of the shaft
Shifting is performed by the lever (1) when the tractor is in
standstill.
a - Independent speed of the output shaft (rpm of the
shaft depends on rpm of the engine).
n - Neutral position. Use this position to facilitate
connection of the farming mechanism propeller shaft.
The terminal of the rear output shaft is freely rotable.
b - Dependent speed of the output shaft (rpm and
direction of rotation depends on the engaged gear and
position of reversing lever).
