BELARUS-1221.2/1221 В .2/1221.3 Description and operation
119
The draft control handle (7) (Fig. E-29) is
located on the right-hand control panel (9),
the first from the operator’s seat. The op-
erational range of the handle positions is
marked with digits from 1 to 9 that corre-
sponds to the entire span of ploughing
depths from minimal to maximal ones, re-
spectively.
The
position control handle
(8) (Fig. E-
29) is located next to the draft control
handle (7). Its operating range is marked
with the same digits which cover RHL po-
sitions from the upper transport position
down to the lowermost position, respec-
tively.
The additional position control handle
(8a) (Fig. E-29) is located on the rear of the
tractor on the hydraulic power lift. Pulling
this handle towards the operator standing
behind the tractor and looking along the trac-
tor forward travel lifts the RHL and pushing
the same from the operator lowers the RHL.
The RHL travel limiter (6) is located in the
slot of the right-hand side panel, in which
the position control handle (8) moves.
The positions of the oil tank, oil pump filter
and the distributor to control external
loads are unchanged. The distributor is of
a sectional flow-through type; it has prior-
ity in control over the hydraulic power lift.
Hydraulic Power Lift (Fig. E-29, E-30)
The hydraulic power lift (Fig. E-29) is in-
stalled on studs, on the rear wall of the
rear axle casing (1) and consists of a con-
trol unit and a regulator-distributor (3) built
in a single casing (monoblock) which
houses two hydraulic single-acting power
cylinders (2).
