REAR HITCH LINKAGE (RHL)
The rear hitch linkage serves for attach-
ing mounted and semi-mounted agricul-
tural machines to the tractor. The
mounted agricultural machines shall be
attached to the tractor at three points: to
the joint of the lower links and that of the
top link, or by means of a pickup quick
hitch mechanism.
The rear axle housings carry brackets
(11), with two cylinders (4) mounted
thereon through pins (10). The cylinder
rods are connected to the external levers
(3) by means of pins (3a) (left- and right-
hand). The external levers sit with their
splined holes on the shaft (2); the latter is
installed in the rear axle cover (1). The
levers (3) are coupled to the lower links
with lower rods (7) by means of the drop
links (5).

The Lower Links
are fitted in brackets
(14) (right- and left hand ones) with their
front joints through special pins (13)
which are draft control transducers. The
brackets are fastened to the side sur-
faces of the rear axle, under the housing
flanges. The lower links have lugs (8), to
which turn-buckle braces (9) are at-
tached with their forks. The braces pro-
vide for adjustment of the agricultural
machine cross-displacement in the work-
ing and transportation position.
The Top (Centre) Link (6)
