6.8.4. Mounting Agricultural Machines
on Tractor. Adjustment of the Rear
Hitch Linkage for Operating and
Transport Positions
Attach mounted machines to the tractor by
means of an automatic coupling device
СА-1 to be fastened to the tractor hitch
linkage at three points (two aft joints of the
lower (draft) links and the aft joint of the
top (control) link).
To prevent spontaneous detachment of
the machine from the tractor, secure the
automatic coupler dog with a spring cot-
ter pin. In so doing, make sure that there
is a distance of at least 70 mm between
the proper shaft and the cross-bar when
the machine is lifted to a position for
transport.
Semi-mounted machines (potato harvest-
ers type
ККУ-2, ККУ-2А, potato digger-
windrower type
УКВ-2) are to be attached
to the tractor by means of a special cross-
bar, provided with the machine and con-
nected to the lower link joints. Also, check
to see that there is a gap of at least 70 mm
in-between the propeller shaft and the
crossbar.
Lift height is limited by a slide stop 1 (see
Fig. 21). When the linkage is lifted, the
stop acts upon the hydromechanical
valve stem (2), and the latter, in its turn,
blocks the cylinder rod-end.
When attached, place the machine level
by changing the length of the left-hand
drop link and the control link.
DO NOT
adjust the left-hand drop link when
running with a mounted implement,
its
length should always be 475 mm. Final
adjustment is to be carried in the field (on
ploughing
– when running the third fur-
row, on other jobs
– on the first run).

When combining the tractor with wide-
span or wide-cut machines, connect
forks (5) and (23) (see Fig. 22) of the
tractor drop links to the lower links slots,
thus, ensuring better accommodation of
work tools to the soil relief along the
span. For operation with the draft (posi-
tion) control not used, connect the top
link to the lower hole in yoke (30).
It should be seen that the lock-nuts of the
drop links, check chains and the top links
are reliably tightened: loose lock-nuts can
disturb the adjustment of the hitch linkage
and thread stripping.
On preparation of the tractor with imple-
ments attached for long-distance trips,
shorten the top link (24) to improve the
passing ability of the aggregate.
Adjusting bolts (8) are screwed into the
brackets (6). These ensure tightening of
the chains when the implement is raised
to a transport position and, thus, lock it
against transverse swaying.
