Aggregation
203
Ploughing is the most power-consuming kind of work. According to the pulling values
the tractor can be aggregated with a four-bodies share plough with a furrow grip width of
30…40 cm by 15..22 cm of cultivation depth on the middle-tight soil of normal humidity.
Traditionally “Belarus” tractors in combination with units are used as per scheme of
«tractor wheels are in a furrow». In this case a relevant wheels placing is required when
working with standard, reverse and turning ploughs.
The type of the plough, the grip width (number of plough-bodies) depends on the soil, its
mechanical makeup, debris infestation, tillage depth. One body of a plough requires ap-
proximately 15...20 kWt on the middle-tight soils by the tillage depth up to 20 cm and 35
cm of the body grip width.
To achieve a smooth ploughing, reverse (doubled) or turning ploughs providing one-
sided layer turn are used.

To obtain a tread size, add a profile width of a relevant tire to A and B sizes.
Despite the variety of ploughs constructions there are some general principals and the or-
der of their preparation to the work with the tractor.
The type of plough is selected according to the running range of the rated pulling forces,
soils type, cultivation depth, and the type of the plough body is selected in accordance with
the agrotechnical requirements.
•
The plough is prepared so that the requirements concerning the technical state of the
operating units, auxiliary devices were met.
•
The part of the aggregate preparation is a correct adjustment of the mechanisms of
the tractor hitch linkage for the set up operating conditions and a preliminary setting the
rear cultivation depth. It is recommended to check the ploughs as well as other soil culti-
vating machines on a specially equipped test area with the hard surface and a striping,
corresponding to the correct positioning of the operating units. Examining using a binder or
