Abstract
A pump system includes an actuator which can be retracted by a fluid in the pump system. Also included is a pump with a first drive coupling and a rotational power device with a second drive coupling. The second drive coupling is configured to removably mate with the first drive coupling for powering the pump. A spool valve that is spring loaded and in fluid connection with the pump when the spool valve is in a stow position is also included. In addition, the pump system includes both a relief valve and a reservoir both in fluid connection with the actuator.
