Trailer attachment frame for farm tractor - uses spiral cable to raise and lower frame

摘要

The hitch for attaching a trailer or a trailing implement to the rear of a farm tractor having a towing device (2) with a frame (10) can be raised and lowered, and which carries the tow bar (14) with the towing hook (15). The raising and lowering movements are achieved by an arm (4) which is connected to the frame by a spiral cable (16) which permits a relative movement of the arm to the frame (17). ADVANTAGE - Trailer system in which the three point coupling is easier to operate, even though the towing device is permanently joined to the lifting arm.
