The rear PTO control lever has two positions:
- shifting lever 2 (figure 2.16.1) from the extreme rear position to the extreme front position
engages the rear PTO;

Switching between the rear PTO speed of 540 and 1000 rpm is carried out exclusively by
installing the corresponding PTO shaft end extensions that have corresponding markings of "540"
and "1000". "BELARUS-2022.6" tractors do not have a special switch between the speeds of 540
and 1000 rpm of the rear PTO.
The rear PTO drive on tractors "BELARUS-2022.6" has two operation modes:
- standard – 540 and 1000 rpm;
- economic – 770 and 1460 rpm under engine rated speed.
Shaft 3 (figure 2.16.2) located on the left of the clutch coupling housing under the HLL
pump, is designed for switching the modes of the RPTO drive.
Switching between the modes of the rear PTO (standard and economic) shall be carried out
only when the engine is off or with the engine min. idle speed. To do this, it is required to loosen
fixing bolt 4 (figure 2.16.2) and turn shaft 3 until engaged into the clutch, after that tighten the fixing
bolt. To engage the standard mode, it is necessary to turn shaft 3 contraclockwise against the stop;
to engage the economic mode it is required to turn shaft 3 clockwise against the stop.
