ABSTRACT:
The foot-operated speed control shaft for the hydrostatic transmission of a garden tractor is provided with an operating handle which is pivoted on the shaft for fore and aft movement, and is slightly flexed laterally. This flexure energizes a friction block which is secured to the handle and slides across a fixed braking surface to arrest the control shaft in any selected rotative position. The upper part of the operating handle includes a tube enclosing a spring-loaded plunger and rod. The rod has a lower end extending past the edge of a quadrant which is secured to the control shaft. According to the position of the plunger, the rod end can be either seated within a notch in the edge of the quadrant, or can be locked out of contact with the notch. Since the quadrant is attached to the control shaft, the two control systems, i.e., the normal foot pedal control and the present handle operated control, are connected together, or disconnected, according to the operative position of the plunger and rod, and the hand control system may be overridden by the foot control system if necessary.
