摘要： A trash plant stem shredder having vertically stacked pairs of parallel, frictionally engaged contra-rotating uprooting rollers are carried by a frame and towed behind a vehicle. The uprooting rollers are tilted forward such that, when a trash plant stem which remains in the ground after harvesting an agricultural product from the plant, enters the nips of the rollers, the stem is uprooted and moved rearwardly along the frame. A contra-rotating feed roller is disposed rearwardly of the uprooting rollers and in abutting relationship thereto, and feeds the stem to a shredder which includes a plurality of vertically stacked cutter units that longitudinally shear or shred the stem into small sections which are scattered and allowed to biodegrade in the field and fertilize the soil. Each cutter unit includes a stationary blade having a leading edge that extends closely adjacent to the feed roller and a rotary cutter blade which is spaced rearward of the feed roller to inhibit accumulation of debris and blockage of the shredder.
