Gripping properties and terrain performance of the BELARUS-82.3 tractors in spe-
cific operating conditions depend on the following factors:
- tractor adhesive weight and ballast used in a specific tractor configuration;
- distribution of weight of the tractor, ballast and machine within tractor unit along trac-
tor axles;
- size of tires and pressure in tires;
- technical condition and workability of tractor undercarriage system;
- proper and timely application of recommendations of the manufacturing plant for
enhancement of tractor tractive performance;
- condition and properties of ground area;
- factor of wheel tire grip with ground area;
A limiting factor in the use of agricultural tractor is the terrain that is characterized by
steepness and configuration of the cultivated areas of the field, as well as their altitude
above sea level. Other influencing factors of the altitude of the field cultivated area are at-
mospheric pressure and ambient temperature. The engine power is reduced by 1.0% per
each 100.0 m of altitude above sea level, while fuel consumption increases to the same
extent.
The BELARUS-82.3 tractors are intended primarily for lowland conditions, and for lim-
ited use, subject to safety measures and recommendations, for areas with a significant
steepness of the slopes with altitude above sea level.
Changing of the BELARUS-82.3 tractor’s terrain performance and gripping charac-
teristics by means of increasing the operating weight within permissible limits is most ef-
fective in the conditions, when bearing power of soil grows up with increasing track depth.
For example, with tractor weight increase due to additional ballasting, on stubble of winter
crops on mineral soils, the tractive power of the tractor increases by 8.8 … 28.3 % on the
hook depending on soil moisture.
4.10.2 Ways of changing tractor gripping properties and passing ability
There are the following ways of changing gripping properties of the BELARUS-82.3
tractors:
- increase of tractor adhesion weight;
- increase of wheel tire-soil adhesion.
To increase the adhesion weight of the tractor, the following options are available:
- use quick-detachable suspended 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 rear wheels.
To obtain information on the rules of rear wheel twinning and operational limits of
tractors with twinned wheel contact your dealer.
4.10.3 Use of quick-detachable hinged ballast weight
Factory-built quick-detachable hinged ballast weights are usually utilized for addi-
tional loading of the tractor front axle and providing a favorable distribution of the tractor
operational weight while working with various agricultural machines.
