TILLAGE
Tillage is one of the most power-
consumptive type of field operations. The
BELARUS tractors of these models can
be used on medium and large fields with
5…7-bottom share ploughs, depending
on soil conditions.
The tractor is used as part of an aggre-
gated tillage combination in line with a
“tractor-furrow” pattern. It requires ap-
propriate wheel arrangement when run-
ning with common, swivel and turnabout
ploughs. Its aggregating with ploughs on
“tractor wheel off the furrow” is also pos-
sible. In this case, the wheel arrange-
ment pattern problem is less stringent. It
is becomes therefore expedient to twin
the rear wheel and improve the tractor
gripping and traction properties, espe-
cially with tyres filled in with liquid.
To obtain smooth tillage, the swivel and
two-way ploughs are used. They provide
for high-quality tillage, without crown
ridges and open furrows. To ensure the
trouble-free and continuous operation of
the tractor, it is recommended to use the
ploughs equipped with automatic protec-
tion facilities: after such a facility comes
into action and the plough passes over
an obstacle, the plough body automati-
cally reverts to its initial position, without
interruption of the tillable aggregate op-
eration.
When preparing for tillage, it is neces-
sary to perform the following works:
• Checking and adjusting as necessary
the rear hitch linkage.
• Rearrangement of the wheel in accor-
dance with the tillage pattern selected.
• Checking and adjusting the plough in
accordance with the directions of its
operating manual.
To obtain the best results in ploughing, it
is important to choose correctly the type
and parameters of the plough. The
plough type, cutting width (the number of
plough bottoms) depend on the soil, its
texture, the degree of contamination with
stones and ploughing depth. Approxi-
mately, one plough bottom requires the
power of 20 kW (on medium soils).
The speed regime of the tillage aggre-
gate should be chosen taking into ac-
count the plough bottom type, soil group
and climatic conditions, and so that the
sufficient traction for overcoming the
draft resistance of the plough and inter-
mittent overloads would be achieved.
To maintain a technologically required
speed and to obtain ploughing of good
quality in case of aggravated soil and
climatic conditions, it is a good practice
to reduce the working width of the plough
by removing the last bottom or in any
other manner, if this operation is pro-
vided for by the plough design.
In case of ploughing of wet soils and on
slopes following a “tractor wheels off the
furrow” pattern, the slipping down into
the open furrow is possible. In such
cases it is preferable to plough using a
“tractor-wheel-in-furrow” pattern, with re-
duced working width.
