Ways Of Changing Drawbar Features And Passing Ability Of The Tractor - Belarus 922.6 Operator's Manual

- after the tractor stop, only after the coupled implement fully completed its duty cycle;
- on turns, when the implement is lifted to the transport position;
- when moving up a steep slope.
Do not engage the PTO shaft in the following cases:
- when the tractor engine is off;
- the implement coupled to the tractor is in transport position;
- when the implement operating parts are sunken into the soil;
-.if the implement operating parts are covered in process material or if the operating
parts are clogged or wedged;
- if there is a considerable slope angle (refraction angle) in any plane of cardan shaft
hinge joints.
While operating rotation tilling machines with active operating parts, it is additionally
required to observe the following rules:
- not to engage the PTO shaft when the implement is grounded. The PTO shaft shall
be engaged only when the ready to operate implement is lowered so that its operating parts
do not touch the ground with the clearance not less than 35 mm;
- lowering of the implement with rotating operating parts shall be carried out smoothly
when the tractor is moving forward;
- during operation prevent the tractor from moving in the direction not corresponding
the implement working travel, when the operating parts are sunken into the soil with the
PTO shaft engaged and disengaged;
- during operation on solid soils it is required to carry out processing of cross ranges
for moving in enclosure, and then process the soil in the lengthwise direction;
- it is recommended to work at the minimum soil processing depth needed for the
specific crop. It is necessary for load reduction on the tractor PTO shaft and for reduction of
fuel consumption during tractor operation. It is particularly important to consider this fact
during tractor operation with multiple-purpose tillage units.

4.10 Ways of changing drawbar features and passing ability of the tractor

There are the following ways of changing drawbar features of "BELARUS-922.6" trac-
tor:
- increase of tractor adhesion weight;
- increase of wheel tire-soil adhesion.
To increase the adhesion weight of the tractor, do the following:
- use quick-detachable hitch ballast weight;
- fill tires with water (solution);
To increase wheel tire-soil adhesion, do the following:
select optimal internal pressure in tires, depending on the operating conditions and
load on tractor axles;
apply rear axle differential lock;
twin the wheels.
Note – Pneumatic pressure rate in the front and rear tires of the tractors "BELARUS -
922.6" under actual load is shown in subsection 3.2.8 "Selection of optimal internal pressure
in tires depending on the operating conditions and load on tractor axles".
To obtain information on the rules of rear wheel twinning and filling of wheel tires with
water (solution), as well as on operating limitations for tractors equipped with twinned
wheels and tires with water (solution) - contact your dealer.
