More specifically, the packer blade is mounted on a carriage that is arranged to reciprocate on an inclined track means so as to load and pack the truck body and the blade and carriage are respectively actuated by separate hydraulic cylinders which are in turn controlled in a novel manner. The control apparatus includes a main power flow circuit for driving the hydraulic cylinders and an associated low pressure fluid signal flow circuit for controlling the flow of oil in the power flow circuit. The signal flow circuit is further characterized by an emergency stop control as well as an optional holding control for certain portions of the cycle of the packer blade.
