5.7.2 Ways of changing of drawbar features and passing ability of the tractors
There are the following means of changing the gripping properties of BELARUS-892/892.2:
- increase of tractor adhesion weight;
- increase of wheel tire-soil adhesion.
To increase the adhesion weight of the tractor the following could be done:
- use of quick-detachable hitch ballast weight;
- filling of tires with water (solution);
To increase wheel tire-soil adhesion the following could be done:
- selection of optimal internal pressure in tires, depending on the operating conditions
and load on the tractor axles;
- applying the rear axle differential lock;
- wheel doubling.
To obtain information on the rules of rear wheel doubling contact your dealer.
5.7.3 Use of mounted quick-detachable ballast
Factory-built quick-
detachable hinged ballast weights are usually utilized for addi-
tional loading of the tractor front axle and providing a favourable distribution of the tractor
operational weight while working with various agricultural machines.
5.7.4 Pouring water (solution) into the tyres of the rear wheels to increase grip
Filling up the tyres with water (solution) is carried out for the purpose of increasing
the adhesive weight (increase in the tractor traction power). Filling the front tyres with water
(solution) is not provided by the tractor design.
ATTENTION: THE LOAD ON THE TIRE WITH THE GIVEN INTERNAL PRESSURE
SHALL BE REDUCED BY THE WEIGHT OF THE FILLED WATER!
ATTENTION: IN CONDITIONS OF SATISFACTORY AND SUFFICIENT TYRE
TRACTION TO THE GROUND, FILLING UP THE TYRES WITH LIQUID IS NOT RECOM-
MENDED BECAUSE OF THE TRANSMISSION OVERLOAD!
ATTENTION: ADDITIONAL LOADING OF WHEELS BY FILLING TYRES UP WITH
WATER (SOLUTION) SHALL BE USED ONLY IN CASE WHEN THE TYRE TRACTION TO
THE GROUND IS INSUFFICIENT IN ADVERSE CONDITIONS (ON SANDY, WATER-
LOGGED SOILS, ETC.). TYRES FILLED UP WITH LIQUID IMPAIR THE SMOOTHNESS
OF TRACTOR TRAVEL AT A SPEED EXCEEDING 15 KM/H, AND IN CASE THE TYRE
RUNS INTO ANY OBSTACLE, CARCASS BREAK CAN HAPPEN!
ATTENTION: IT IS FORBIDDEN TO FILL IN THE TYRES WITH WATER (SOLU-
TION) FOR MORE THEN 75% OF THEIR VOLUME AS OVERSIZE AMOUNT OF LIQUID
CAN RESULT IN TYRES BREAK-DOWN (TYRE THREADS OR INNER TUBES)!
Use of water (solution) to fill the rear tyres increases significantly tyre stiffness, track
depth and compaction of soil. If it is essential to use water (solution), it is recommended to
fill in all tyres up to equal levels not exceeding 40%.
Water (solution) volume per one tyre for 40% and 75% fill are shown in Table 5.7.1.
ATTENTION: FILLING IN THE TYRES WITH WATER (SOLUTION) FOR MORE
THAN 40% SHALL BE APPLIED AS THE LAST RESORT!
