2.17.1
Lever shifting rear PTO from continuous drive to ground-speed drive
When lever 44 (Figure 2.1.1) is shifted in the far left position (along tractor
movement) ground-speed drive becomes engaged, and if it is shifted in far right position –
continuous drive becomes engaged, and if it is placed in the middle – “neutral” position.
ATTENTION: ENGAGE GROUND-SPEED DRIVE OF REAR PTO ONLY FROM
NEUTRAL POSITION WITH THE ENGINE IS RUNNING AT LAW GEAR OF THE FIRST
OR SECOND RANGES OF GB ON THE MOVING TRACTOR. OTHERWISE POWER
TRAIN DAMAGES ARE POSSIBLE! SHIFT PTO GROUND-SPEED DRIVE TO A NEU-
TRAL POSITION IN A SIMILAR WAY!
ATTENTION: SHIFT PTO CONTINUOUS DRIVE FROM NEUTRAL POSITION
ONLY WITH ENGINE SHUT DOWN! SHIFT PTO CONTINUOUS DRIVE TO A NEUTRAL
POSITION IN A SIMILAR WAY!
2.17.2
Rear power take-off shaft engagement
Engagement of rear PTO is possible only when lever 44 (figure 2.1.1) is shifted in
position “ground-speed drive of rear PTO is engaged” or in position “continuous drive of
rear PTO is engaged”. Rear PTO shall not operate in "neutral” position.
On tractors with electro-hydraulically control the rear PTO is engaged by button
switch 5 (figure 2.15.1) and by button switch 4 situated on the control panel for rear axle
and PTO differential lock 41 (figure 2.1.1). The switch has two fixed positions:
-
„PTO engaged“- by pressing on the lower part of the switch 5 (figure 2.5.11);
-
“PTO disengaged” - by pressing on the upper part of the switch 5.
To engage the PTO do the following:
- press the lower part of the switch 5;
- press short the button switch 4. The pilot lamp 3 goes on and PTO starts to rotate.
To disengage the PTO, press the upper part of the switch 5. The pilot lamp goes out and
PTO stops.
ATTENTION: ON TRACTORS WITH ELECTRO–HYDRAULICALLY CONTROL
THE PTO IS AUTOMATICALLY OFF AT ENGINE STOPPING.
On tractors with mechanical control the rear PTO is engaged by the lever 3 (figure
2.27.1).
The rear PTO engaging lever 3 (figure 2.27.1) has two positions:
- at shifting the lever 3 from extreme front position to extreme rear position the rear
PTO becomes engaged.
- at shifting the lever 3 from extreme rear position to extreme front position the rear
PTO becomes disengaged.
It is recommended to engage and disengage rear PTO with the engine running.
In figure 2.17.1 the rear PTO engaging lever 1 is set into position „rear PTO disen-
gaged“.
