in the aggregation peculiarities and have different performance characteristics and adjust-
ments.
Usually, the operational documentation for the machines manufactured by reputable
manufacturers considers the matters of correct intended use of the machines including the
recommendations for selecting and aggregating the tractor as well as safety procedure in
sufficient details. In any case, the manufacturer (seller) of the machine shall provide you 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 char-
acteristics of the machines to be coupled with your tractor, the hitch (if necessary) and addi-
tional 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 op-
eration 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 im-
plements and tyres as well as allowable load on the traction hitch mechanism and axles of
the tractor.
The MTZ tractor can be aggregated with the machines having the rated resistance of
the tools of 1.4 kN.
The grasp width of the aggregate and operating depth depend mainly on the specific re-
s i s t a n c e o f t h e s o i l s , w h i c h d e t e r m i n e t h e r a n g e o f o p e r a t i n g s p e e d s w i t h t h e a c c o u n t o f a g r i c u l t u r a l
requirements. The heavier is the soil, the higher is the specific resistance.
Based on the tractive force range of 12.8...18 kN provided by the MTZ tractor on the
stubble field, the approximate calculation of the grasp width of the commonly used power-
intensive agricultural machines with these tractors (see Table 1). The specific resistance is
given for the operating speed of 5 km/h. Variation of the speed by 1 km/h varies the specific
resistance by the value of up to 1%.
The interrow cultivation of row crops is provided using the narrow tyres from addition-
al equipment in the row-spacing of 450 to 900 mm. However, the interrow cultivation of maize,
cotton and similar cultures using the tyres from the standard equipment is also possible.
Based on its tractive capacity, the tractor can be aggregated with a 4…6-row complex
of machines for cultivation of potato in stitches, a 12-row complex for cultivation of sugar
beet, 8…12-row complex for cultivation of maize, sunflower, soya and other similar crops.
