ABSTRACT:
A mechanism for controlling raised and lowered positions of a hitch-mounted implement includes a rotatable control knob coupled to a transducer, e.g., a potentiometer, for movement between first and second positions representing the raised and lowered positions, respectively, of the implement. The control knob has a button for locking the mechanism in the implement-transport position and for other purposes. A position knob includes a tang-like stop for limiting rotation of the control knob toward the second position. The position knob thereby "sets" a lowered position of the implement which is somewhat above the lowest possible position of the implement. The position knob may be rotated to locate the stop anywhere between two barriers which set the overall limits of travel of the control knob. Most preferably, the position knob is clamped between a barrier member and a console surface and is frictionally inhibited from rotating.
