Refuse loading apparatus for use in conjunction with a vehicle having a refuse storage body and a hopper for receiving refuse to be loaded includes a hydraulically operated packer plate for loading refuse from the hopper into the storage body. The packer plate is powered by means of a first pair of hydraulic cylinders which causes rearward and forward motion of the packer plate, and a second pair of hydraulic cylinders which controls the elevation of the packer plate in relation to the bottom of the hopper. A pair of hydraulic valves, mounted on the packer plate and operatively engaged to cam tracks on the side walls of the hopper, sense movement of the packer plate away from the bottom of the hopper and modulate the fluid outflow from respective ones of the second pair of cylinders to maintain the packer plate in close association with the bottom of the hopper for improved loading efficiency.
