Abstract
A material eject system includes an ejector mounted to a bed of a vehicle which is movable between a rear end and a forward end of the bed for ejecting material from the bed. The ejector is powered by a cylinder having different fluid volumes depending on the direction of motion of the cylinder. Two pumps having flow rates matching the different fluid volumes of the cylinder are used to power the cylinder in the different directions.
