The main direction of reducing the cost of soil
treatment based on resource-saving technologies is
the transition to surface treatment of soil with disk
tools. Double-row and four-row disc tools are manufactured.
Four-row tools significantly increase
tillage intensity. In the disk tools, the spherical disc
is fixed on the individual pole. Disc headers are
equipped with a rigid adjustment fixing the
standalone pole to the frame. Recommended operating
speed is up to 12 km/h. The advantage of a disc
header over the disc harrow is as follows: winding
plant residues on the axis are excluded. Disc
mulchers are equipped with a spiral bar on which a
spherical disk is mounted. The presence of the elastic
element allows the working unit to do lowfrequency
oscillations during movement. The result
of processing is the formation of mulch in the layer
of soil, which is a mixture of plant residues and soil
particles with a diameter of up to 25 mm. To assess
the effectiveness of the disc mulcher and the disc
header a unit is composed. The initial data for calculation
are as follows: tractor HTZ-150K, the resistivity
of the soil is 6 kN/m, disk tool working
width is 4 m, operating speed of the disc header is
12 km/h, operating speed of the disc mulcher is 15
km/h. Technical and economic performance of these
units is defined during disking the soil. The
choice of energy-saving operating regime was made
in a well-known manner. Theoretical value of slippage
of the leading tractor with disk mulcher was
6%, against 9% with the disc header. Working
speed of the mulcher made up 14.07 km/h against
10,89 of the disc header. The performance of the
unit with the mulcher made up 16.21 hectares, disc
harrow performance is 12,54 ha. Fuel mass flow of
mulcher decreased by 29% and made 9.68 kg/ha.
Using mulcher for surface treatment of the soil allows
to reduce the tillage energy costs thanks to
resource-conserving technologies
