2.14.6 Annunciation of emergency oil temperature in the hydraulic lift linkage

The annunciator of emergency oil temperature in the hydraulic lift linkage tank 8
(figure 2.14.1) lights up when oil temperature in the hydraulic lift linkage tank exceeds the

2.14.7 Rear PTO control

The handle to engage the rear PTO drive 22 (figure 2.1.1) has two positions:
- upper position – "PTO drive engaged";
- lower position – "PTO drive disengaged".
The rear PTO control lever (figure 2.14.2) has two positions:
- shifting the lever 2 from the rear extreme position to the front extreme position en-
gages the rear PTO;
- shifting the lever from the front extreme position to the rear extreme position dis-
engages the rear PTO.
Note – The PTO control lever 2 in figure 2.14.2 is set into position "PTO disen-
gaged".
1 – instruction shield for rear PTO control; 2 – rear PTO control lever.
In BELARUS-2022.3/2022 .3 tractors the shaft for switching modes of the rear PTO
drive 38 (figure 3.2.7) is located to the left on the coupling clutch body under the HLL
pump.
The rear PTO drive has two operation modes:
- standard – 540 and 1000 rpm;
- economy – 770 and 1460 rpm under engine rated speed.
Switching between the modes of the rear PTO (standard and economy) shall be
carried out only with the engine killed or with the engine min. speed. To do this it is re-
quired to loosen a fixing bolt 39 (figure 3.2.7) and turn the shaft 38 until engaged into the
clutch, after that tighten the fixing bolt. To engage the standard mode it is necessary to
turn the shaft contraclockwise against the stop, to engage the economy mode it is required
to turn the shaft clockwise against the stop.
In BELARUS-1822.3/1822 .3 tractors the rear PTO economy mode and the shaft
switching between the modes of the RPTO are missing.
Switching between the rear PTO speeds of 540 and 1000 rpm is carried out exclu-
sively by installing the corresponding PTO shaft end extensions, that have respective
markings of "540" and "1000". BELARUS-1822.3/1822 .3/2022.3/2022 .3 tractors do not
have a special switch between the speeds of 540 and 1000 rpm of the rear PTO.
Note – The RPTO operation is controlled over the integrated indicator, as specified
in subsection 2.7.2 – "Assignment and operation principle of the integrated indicator
gauges".
Note – Additional information on the RPTO operation rules is given in subsections
4.2.7 "PTO use" and 5.9 "Power takeoff shaft ends".
