A trailered, short stroke reduction grinder including a telescoping, multi-stage push ram and hydraulic grinding head which are operable from seat mounted joy sticks in an enclosed operator cabin. Collected reduction materials are pushed to a grinding channel defined between multiple arcuate, sizing screens and the rotating grinding head. A hydraulic shear bar controls the entry of the material to the grinding channel. The grates of the sizing screen are arranged to provide a plurality of reduction apertures of progressively increasing size and differing geometric shape. A single hydraulic motor and belt drive linkage control the grinding head and permit forward and reverse operation. High density plastic slide bearings at cross supports of a discharge conveyor support a ribbed belt.
