ABSTRACT:
A machine for shredding stalk, particularly that of cotton, is disclosed which comprises a wheeled frame adapted to be trailed along crop rows, a power driven unit, and a stalk puller device. The device comprises a pair of frictionally coupled rollers, at least one of which being rotatably driven by the power unit about an axis forming an acute angle with respect to the vertical. Stalk which becomes engaged between contacting circumferential portions of the rollers is pulled, plucked from the ground and fed in a generally backwards direction by the rollers. A first shredding device is provided comprising a series of cutting knives rotating in a direction away from the rollers. The cut stalk becomes airborne and is conveyed backwards along a first, streamlined shroud member overhanging the first shredding device. A second shredding device of similar construction is installed, operating in tandem with the first shredder, whereby the stalk is cut into small chips and discharged from the machine.
