A dump body latching system for application to a self-dumping hopper having a base platform, a rotatable dump body mounted thereto and a locking pin on the rotatable dump body is configured to control rotation of the rotatable dump body thereon. The dump body latching system includes a power source, an actuator assembly including an actuator, and a controller operably connected to the actuator. The controller operates to selectively connect the power source with the actuator to selectively disengage the locking pin.
