ABSTRACT:
A mechanical system for a controlling a reversible pump in a walk-behind turf care machine having a hydrostatic drive and operator speed and traction controls. The pump includes a rotatable trunion shaft connected to the traction control for controlling hydrostatic pump displacement and direction. A rotatable lever structure fits over the trunion shaft and includes a rotary sleeve, an arm and roller. A control bracket, including a V-shaped contact portion having opposed surfaces for engaging the roller, is operatively connected to the speed and traction controls and to the turf machine frame about a pivot point. Operator manipulation of the control bracket via the speed and traction controls causes a rotatable engagement between the control bracket and the roller, which in turn sets the maximum forward/reverse speeds and direction of the hydrostatic drive. When the traction control is neutral, a spring arrangement is provided for urging of the hydrostatic pump into its neutral position. An improved operator station is also provided.
