Abstract: A material handling system comprising a mobile longitudinally extending receptacle having a bottom, side walls, forward end wall and pivotally movable end gate. Inside the receptacle is a pusher blade extending generally from side to side, the pusher blade being mounted for longitudinal movement between a first position adjacent the forward end of the receptacle and a second position adjacent the rear end of the receptacle. A hydraulic system is used to move the pusher blade. The blade is mounted for movement by a system including, at each side of and within the receptacle and extending longitudinally therealong, a lower upwardly facing guide track and an upper downwardly facing guide track. Slide blocks are mounted on the blade to bear against these tracks. The blade is shaped to move the material inwardly from the sides, downwardly from the top and upwardly from the bottom as the blade moves rearwardly.
