Abstract

A ride-on zero-turn work machine has two drive control levers longitudinally pivotable for locomotive and steering control, and laterally tiltable inboard and outboard for parking brake control. Two brake control linkages are each connected between one of the levers and one of the parking brakes. Each linkage features a rotatable bell crank, a brake connection link running from the bell crank to the parking brake, and a lever connection link having one end coupled to the bell crank, and another coupled to drive control lever. The bell crank is a flat plate to which the links are coupled at a same common side, and whose outer perimeter includes a cam profile that is engaged by a cam follower to resist movement of the control lever between inboard and outboard positions. The perimeter edge of each bell crank also engages a position detection switch in one of the inboard and positions.
