To adjust the bolts (8), proceed in the
sequence as follows:
а) couple the implement with the lower
and top link joints. Screw in the ad-
justing bolts (8) as far as they go;
b) raise the implement a bit, so that its
tools lose contact with the ground;
c) adjust the length of check chains by
rotating the turn-buckles, so that the
lower link joints are free to sway in
accordance with the instructions giv-
en in the user’s guide to this imple-
ment. For mounted ploughs the
sway in the horizontal plane should
be 125 mm to either side from their
midposition.
d) adjust the length of the right-hand
drop link to the prescribe tilling depth
(when working with ploughs);
e) raise the implement to a transport
position; screwing the bolts (8) out of
the brackets, tighten the chains until
they sag slightly and limit implement
sway within 20 mm to either side
стороны;
f) secure reliably the bolts (8) with the
lock-nuts.
Each time changing the length of the
right-hand drop link should be followed
by the adjustment of the right-hand
bracket bolt to ensure self-locking of the
check chains.
In the case of inter-row cultivation, sow-
ing, or seeding, as well as when running
with a haul-and-draw coupling device
ТСУ-1Ж involved, lock the lower links in
full from transverse movements, lest the
implement sway and plants be damaged.
Link adjustment is made by way of
shortening the chain length as much as
possible, within the limits they have been
set before. In this case, drive the adjust-
ing bolts fully home into the brackets.
Violation of the procedure described
above may result in check chain break-
age or other break-downs. To avoid
spontaneous drop, interlock the hitch
linkage
with
the
attached
ma-
chine/implement in the position for
transport. To do this:
In case of the tractor with a small-
scale cab (see Fig. 23):
а) open the tractor rear screen;
b) raise the hitch linkage to its top posi-
tion be setting the distributor handle
to the «Lift» position".
Рис. 23.
Hitch linkage locking mechanism of the
tractor equipped with a small-scale cab: 1
—
catch; 2, 3
— rods; 4 — hydraulic cylinder brack-
et; 5
— pin; 6, 7 — levers; 8 — bracket; 9 —
spring; 10
— rest; 11 — control rod: 12 — turning
lever; 13
— control handle.
The rest (10) of the cylinder hydrome-
chanical valve should be in its extreme
position on the hydraulic cylinder rod;
c) push the control handle (13), and
with it the locking mechanism, into
the bottom position;
d) place the distributor handle to the
«Float» position. Under the action of
the implement the turning lever (12)
will turn; now, the cog should enter
into contact with the catch (1).
