6.5 Connection of the hydraulic system of agricultural machines, implements and
vehicles with tractor drawbars
The following elements are provided to connecting the tractor with agricultural machines,
implements and vehicles (see Table 1): mounted 3-point device, hitch iron, hydraulic hook.
The mounted implement provides connection with mounted agricultural machines and
implements having three connecting elements, with butt-joining with the central track rod and
lower links with Walterscheid connection; with semi-mounted implements having two connecting
elements, with butt joining with the lower links with Walterscheid connection. The connection
shall be carried out as follows:
а) install globe joints on the axles of trailing agricultural machines or implements;
b) set the agricultural machine or implement in the operating position on the even ground
and smoothly approach at the rear gear so that the trailing device of lower links should be
below the ball hinge pivots;
c) lift lower links 7 (Fig. 26a) by means of hydraulic cylinders until the locks get operated;
d) by regulating vertical strut 6 adjust the difference over the height of axles of trailing
implement;
e) disconnect central track rod 1 from bracket 3, connect it to the pillar on the frame of
agricultural machine (implement) and fix by means of axle-pins.
