Pto Drive Of Agricultural Machines; Work With Pto Shaft; The Gear Shift Lever Of Dependent And Independent Revolutions - Low Air Pressure In The Air-Pressure System Of The Tractor - Zetor Proxima CL 80 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.
Within any repair or modification on the implement powered by PTO or within any operation on
terrain in its working range the tractor engine ought to be switched off (ignition key in position 0).
When working with the PTO shaft pay attention to proper attachment of all covers.
When the work is finished, always mount the cover of the PTO shaft back.
Connection and disconnection of the transmission shaft of the aggregated machine to the rear PTO
shaft of the tractor must always be performed with the stopped engine, deactivated PTO shaft and
with the gear shift lever of dependent and independent revolutions of the PTO shaft in the position
'N' - neutral!
The gear shift lever of dependent and independent revolutions - low air pressure in the air-pressure
system of the tractor
If there is a low air pressure in the air-pressure system of the tractor, the red signal lamp of the
low air pressure on the instrument panel is activated and the gear shift lever of dependent and
independent revolutions of the rear PTO shaft must always be in the neutral position (n).
If there is a low air pressure in the air-pressure system of the tractor and the gear shift lever of
dependent and independent revolutions is moved from the position (n) to the position (a), an audio
signal is generated and the engine is shut off.
If the gear shift lever of dependent and independent revolutions is in the position (a) and the air
pressure in the air-pressure system of the tractor drops, the red signal lamp of the low air pressure
on the instrument panel is activated, an audio signal is generated and the engine is shut off.
The decrease of air pressure in the air-pressure
system of the tractor is indicated by a short-time
activation of a warning on the display of the
instrument panel and with an acoustic signal.
