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 through a ball joint that, in an inboard position of the lever, and throughout a full longitudinal pivot range thereof, lies on the lever's pivot axis, with no motive effect on the bell crank or parking brake. Laterally outward tilting of the lever moves the ball joint off axis, in a manner driving rotation of the bell crank, and thereby actuating the parking brake.
