  • Control system and method for braking a hydrostatic drive machine
    Patent number: 8261544
    Abstract: A method of braking a hydrostatic drive machine includes steps of reducing a displacement of a pump of a hydrostatic drive system to a non-zero displacement, and increasing a displacement of a motor of the hydrostatic drive system to a displacement that is less than a maximum displacement. The method also includes a step of accelerating an engine of the hydrostatic drive system toward a desired engine speed range.
