A material reducing apparatus is provided. The material reducing apparatus includes a hydraulic pump, a rotary reducing component, a primary hydraulic circuit, and a secondary hydraulic circuit. The primary hydraulic circuit includes a hydraulic motor that drives rotation of the rotary reducing component, an inlet line for delivering pressurized hydraulic fluid to an inlet of the hydraulic motor, and an outlet line for receiving the hydraulic fluid from an outlet of the hydraulic motor. The primary hydraulic circuit also includes at least one braking valve in fluid communication with the outlet line of the hydraulic motor, and a hydraulic accumulator in fluid communication with the inlet line. The hydraulic accumulator is sized to contain a stored volume of pressurized hydraulic fluid. The secondary hydraulic circuit includes an actuator that is selectively driven by pressurized hydraulic fluid from the hydraulic pump.
