1 – center pin; 2 – handle for lifting center pin; 3 – handle; 4 – yoke rear wall; 5 – detent.
To change the attaching points in the coupling clevis lifting device along the height, it is re-
quired to turn handle 3 (figure 4.4.7), after which the coupling clevis shall come down and get fixed in
the next lower fasteners of the lifting device. To mount the coupling clevis up along the height, it is
required to turn handle 3, after which pull handle 3 up. The coupling clevis shall get fixed in the next
upper openings of the lifting device.
To couple agricultural machines to the coupling clevis, it is required to uplift center pin 1 by turn-
ing handle 2. After that move the tractor closer to the agricultural machine. At the moment of contact
between the agricultural machine towing eye with the rear wall of yoke 4, detent 5 shall come into ac-
tion and center pin 1 shall come down providing coupling between the agricultural machine and the
tractor.
On agreement with MTW, the customer is allowed to purchase the coupling clevis manufac-
tured by another company rather than "Walterscheid" and mount it onto the tractor, if the parame-
ters and coupling dimensions of this coupling clevis comply with the parameters and coupling di-
mensions set forth in Table 4.4.6.
ATTENTION: WHEN COUPLING TRAILERS, TRAILED MACHINES, SEMI-TRAILERS
AND SEMI-TRAILED MACHINES TO THE COUPLING CLEVIS AS A PART OF DRAWBAR
HITCH, IT IS REQUIRED TO TAKE INTO ACCOUNT THAT PERMISSIBLE LOAD IN THE HITCH
POINT IN THE LONGITUDINAL DIRECTION SHALL CONSTITUTE NOT MORE THAN 70.1 kN
(INDICATED ON THE LIFTING DEVICE SIDE MEMBERS), REGARDLESS OF THE VALUE IN-
DICATED ON THE AUTOMATED DEVICE PLATE!
