The ability to change vehicle speed and direction without shifting gears or changing engine speed makes the hydrostatic transmission an economical and efficient driveline component. Proper sizing of the pump and motor for the application is the first step in insuring reliable components are provided for the driveline. In addition to correct sizing there are other application parameters that need to be given equal attention. Control forces, fluid filtration, and fluid cooling are items that are easily overlooked but are critical for realizing above average application reliability. This paper discusses hydrostatic transmissions as applied to several types of commercial turf maintenance vehicle drive systems. The information provided is intended to serve as an application guideline for selecting a hydrostatic transmission. Specific customer vehicle requirements must be considered when applying hydrostatic transmissions on commercial turf vehicles.
