BELARUS- 1523/1523В /1523.3 /1523В.3 Aggregating the Tractor
207
The availability of the standard and addi-
tional equipment for aggregating makes
it possible to use the tractors in agricul-
ture in various combinations for power-
consuming applications.
The working width and operating depth
of an implement/machine depend basi-
cally on the specific resistance of soils
which defines the operating speed range
with due account of the agricultural re-
quirements. The heavier is the soil, the
higher is the unit resistance. Based on
the average traction effort of 27...36 kN
developed by a Class 3 tractor on a
stubble field, a rough estimate of the
working width for the main power-
consuming agricultural machine coupled
to a tractor on average soils has been
made. The results shown make it possi-
ble to choose agricultural ma-
chines/implements by their working
widths including echelon arrangement
obtained by means of coupling devices
(harrows, cultivators, seeding machines,
etc.). The figures given in Table 7-22 are
approximate.
Technical means
Unit resistance Р for medium
soils, kN/m, at a speed of v * = 5
km/h
Feasible working width, m
Share plough 12...14 2,0...2.5
Disk harrows 1.6...2.1 up to 12
Share scufflers 6.0...10.0 3...4
Cultivators 1.6...3.0 up to 10
Sowing machines 1.2...1.8 up to 12
Reaping machines 1.2...1.5 up to 15
Combine harvesters:
silage harvesters 2.6...3.3 up to 3.0
beet combine
6...12 up to 3.0
potato harvester
10...12 up to 2.7
* A change in speed by 1 km/h results in the augmentation of unit resistance by up to
1%
