To unlock the hitch linkage, proceed as
follows:
а) raise the hitch linkage to the extreme
top position be setting the distributor
handle to the «Lift» position;
b) pull the handle (13) to the top posi-
tion.
For Tractors with a Unitized Cab
hitch
linkage locking and unlocking procedures
are performed in a similar manner; in do-
ing so, the hitch linkage is raised and
dropped by the draft control lever (the
right-hand distributor handle on tractors
where the draft control is not installed),
while the locking mechanism is raised
and lowered by shifting the lever (40)
(see Fig. 3b) into the extreme left- or
right-hand position, respectively.
6.8.5.
Control of the Tractor Hydraulic
System and Hitch Linkage Using a
Distributor
On tractors without draft (position) con-
trol facility installed the hitch linkage con-
trol is achieved by means of the last
right-hand handle of the distributor.
When running with tractor-mounted im-
plements/machines, use only the «Lift»
and «Float» positions of the handle.
When operating with mounted tilling
machines/implements, NEVER set the
handle to the «Drop» position!
The «Drop» position shall only be used
to control remote-operation cylinders in-
stalled on the machine and intended for
the adjustment of tools (reels, headers,
and the like) of harvesting, sowing and
other machines. If, on completion of the
cylinder stroke, the handle fails to auto-
matically regain its neutral position, do it
by hand. On the contrary, in case of
premature return of the handle, hold it
back to complete this or that operation.
6.8.6. Control of the Tractor Hydraulic
System and Hitch Linkage Equipped with
a Draft (Position) Control
Draft Control
The draft control ensures maximum per-
formance in power-intensive agricultural
operations, such as ploughing, hoeing in
depth, cultivation when in combination
with mounted farm machines.
When ploughing with ploughs Type
ПНЗ-
35
Б, ПЛН-3-35, raise the plough ground-
engaging wheel to its extreme upper po-
sition.
Ploughing to a shallow depth (less than
20…23 cm) when the density of soil var-
ies significantly along the bout (sand-
clay), be sure to drop the plough ground-
engaging wheel as a precautionary
measure to limit maximum depth on plots
of low density.
In case of general cultivation and/or deep
hoeing, with the tractor ganged up with
agricultural machines equipped with two
ground-engaging
wheels
within
the
broad-gang width, set the ground-
engaging wheels to a desired height,
thus obviating possible cross skewness
of the agricultural machine, erratic loads
on the tools farthest to the left and right.
In preparation of an aggregate for draft
control operation duty, proceed with ad-
justments, as follows:
1. Set the hitch compression control link
to the upper hole in the yoke (30) (see
Fig. 22).
2. Couple
the
mounted
imple-
ment/machine to the tractor hitch link-
age.
