Recommended.
To connect agricultural machines to the Piton-Fix coupling , it is required to remove
pin 1 (figure 4.4.10), turn rest 2 in the horizontal direction, mount the agricultural machine
towing eye onto tow pin 3, set rest 2 and pin 1 in the initial position.
On agreement with MTW, the customer is allowed to purchase the Piton-Fix coupling
manufactured by another company rather than "Walterscheid" and mount it onto the trac-
tor, if the parameters and coupling dimensions of this Piton-Fix coupling comply with the
parameters and coupling dimensions set forth in Table 4.4.8.
ATTENTION: WHEN COUPLING TRAILERS, TRAILED MACHINES, SEMI-TRAILERS
AND SEMI-TRAILED MACHINES TO THE PITON-FIX COUPLING AS A PART OF DRAW-
BAR 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 AND PERMISSIBLE VERTICAL LOAD IN THE HITCH POINT SHALL CON-
STITUTE NOT MORE THAN 20 kN (INDICATED ON THE LIFTING DEVICE SIDE MEM-
BERS), REGARDLESS OF THE VALUES INDICATED ON THE "PYTHON" DEVICE PLATE!
