Ways Of Changing Of Drawbar Features And Passing Ability Of The Tractors; General Information - Belarus 1822.3 Operator's Manual

5.12 Ways of changing of drawbar features and passing ability of the tractors

5.12.1 General information

Most of the technical processes in agricultural industry are carried out by tractors
"BELARUS -1822.3/1822 .3/2022.3/2022 .3" in running order by the direct drafting of the
implements and instrument due to the adhesion of pneumatic tyres with surface. Estimated
figures of the towing performance are drawbar power at operation range speeds, rated
drawbar power at standard operating weight, and permissible sliding.
Tractive effort generated on a tyre rim is directly proportional to the tractor adhesive
weight. Therefore in certain conditions drawbar indexes and passing ability increases to-
gether with increase of the tractor operating weight.
Tractors "BELARUS - 1822.3/1822 .3/2022.3/2022 .3" are designed for operation
with definite values of weight loads on the tractor body and chassis. Compliance with the
recommendations on additional ballasting according to operational environment ensures
safe and proper operation without extreme loads on the tractor through not less than the
specified service life.
Tire capacity depending on tires standard size and internal pressure practically
serves as the limit of adhesive weight increase. The manufacturer shall specify the per-
missible maximum loads on the two-speed drive axles at the maximum traveling speed.
Note – Pneumatic pressure rates for the front and rear tires of the tractors "BELA-
RUS -1822.3/1822 .3/2022.3/2022 .3" under the actual load are shown in subsection 4.2.8
"Selection of the optimal inflation pressure of tire depending on operating environment and
load on the tractor axles, and depending on tires operation rules".
Drawbar features
1822.3/1822 .3/2022.3/2022 .3" in the specific operating environment depend on the fol-
lowing factors:
- tractor adhesive weight and ballast used in a specific set;
- tractor, ballast and implement weight distribution along the axles in structure of the
unit;
- standard size and pressure of the tires used;
- technical condition and operability of the tractor chassis;
- adequate and timely application of recommendations of the manufacturing works
on improvement of the tractor drawbar features;
- status and features of the supporting surface;
- wheels tires adhesion to the supporting surface coefficient.
A distinction is made between flotation and cross-section passing ability of an agri-
cultural tractor. Basic flotation defines possibility to move on soils with various structure
and firmness: usually in road conditions in the early spring or in the autumn, on peat-bog
soils, a snowy virgin soil. Cross-sectional passing ability defines possibility of the tractor
movement according to a vertical road clearance and fordable depth.
Agricultural tractors application is limited by terrain relief described by slope and
configuration of the field cuts, and their altitude. The field cut height influence coefficients
are the atmosphere pressure and the ambient temperature. Engine power is decreased by
1.0% per each 100.0 m of height exceeding sea level and the fuel consumption is in-
creased quite as much.
Tractors «BELARUS-1822.3/1822 .3/2022.3/2022 .3» are designed primary for flat
conditions and restrictedly for terrain with significant slope gradient and altitude.
