ABSTRACT:
A work vehicle having a hydrostatic drive system provides for the recovery and reuse of the vehicle's kinetic energy by conducting pressurized hydraulic fluid out of the hydrostatic drive system into an accumulator during vehicle deceleration, and conducting the pressurized fluid back into the drive system during vehicle acceleration to assist the vehicle's engine in accelerating the vehicle.
