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. A control circuit operates with the ejector motor to automatically move the ejector through eject and return cycles. The control circuit further provides a short repetitive retract and eject cycle at the end of the eject cycle to break loose any material that may be sticking the ejector.
