on your request with the information on the basic minimum characteristics of the tractor
which shall ensure the possibility of aggregation of the machine.
The formation of a tractor-based aggregate consists in determining the number and
characteristics of the machines to be coupled with your tractor, the hitch (if necessary) and
additional equipment to be used, adjustments and settings to be performed and the gear to
be engaged. However, it is necessary first of all to purchase the machines. The procedure
of formation of the tractor-based aggregates and peculiarities of the work are given in the
operation manuals for the technical means to be aggregated. In every case, it is necessary
to check the compatibility as to coupling members, load-carrying capacity of the mounted
implements and tyres as well as allowable load on the traction hitch mechanism and axles
of the tractor.
The BELARUS tractor can be aggregated with the machines having the rated resis-
tance of the tools of 20,0 kN.
The grasp width of the aggregate and operating depth depend mainly on the specific resis-
tance of the soils, which determine the range of operating speeds with the account of agricultural
requirements. The heavier is the soil, the higher is the specific resistance. Changing of the speed
for 1km/h changes the specific resistance by 1%.
Attention!
It is very important that the manufacturer (seller) of the machine would provide the in-
formation on the characteristics of the tractor, which would ensure the possibility of opera-
tion of the machine in sufficient details. If such information is unavailable, we recommend
to refrain from purchase (operate) such a machine to avoid possibly heavier troubles in the
process of its aggregation, which could cause the breakdowns of the tractor.
The possibility of aggregation and selection of the machines for the tractor can be de-
termined independently by experimental or calculating method or on the basis of tests per-
formed previously by the respective organizations, for example, zonal machine-testing sta-
tions, as well as recommendations of the machine manufacturer.
Calculation method of aggregation.
When using the calculation method, the calcula-
tions are performed according to the appropriate formulae on the basis of the initial data
and technical reference literature, the respective characteristics of selection of the tractor
and machine are compared and on the basis of this comparison the conclusion on the
possibility of their aggregation is made. This method can be recommended for approxi-
mate calculations in cases where experimental data are unavailable or where it is neces-
sary to know immediately the approximate composition of the machine-tractor aggregate.
Since the calculations use the medium values and all the peculiarities of the aggregation
may not be taken into account, the tractor-based aggregate formed in such a way can be
inoperable in some cases and its additional adjustment in the process of field work can be
required. This method can be recommended for approximate calculations in cases where
experimental data are unavailable or where it is necessary to know immediately the ap-
proximate composition of the machine-tractor aggregate.
When using reliable data and taking into account all the power inputs and local condi-
tions, the possibility of aggregation of the machine with the tractor can be checked suffi-
ciently accurately. Such operational calculations are recommended prior to purchasing a
new machine.
Experimental method of aggregation.
When using the experimental method, the ma-
