摘要： An implement-positioning apparatus used on an implement-towing vehicle such as a tractor includes a draft arm, a lift link, and a mechanism coupling the arm and the link together. The mechanism selectively permits floating arm movement (and therefore floating implement movement) relative to the link. In the improvement, the mechanism includes a clevis-like attachment member fixed on the link and having two arms, each with a slot extending therealong. A pivot-mounted selection member is coupled to the attachment member by a pin through the slots and moves between a first position engaging the attachment member and a second position away from the attachment member. When the selection member is in the second position, the pin is free to move along the slots and thereby permit the draft arm and the implement coupled thereto to "float" and, within limits set by the length of the slots, seek its own elevation under the urging of external forces.
