A material reduction apparatus has a material loading bin for receiving material to be reduced. Below the bin is located a plurality of substantially parallel cutter bars with opposing ends and cutting tips thereon. The cutter bars are supported below the bin. Crank means are pivotally connected to at least one end of each cutter bar for alternatingly moving each cutter bar upward and downward as well as parallel in line left to right unlike the movement of the adjacent cutter bar for kicking, tossing and cutting the material to be reduced.
