-23- "STRAW CHOPPER AND SPREADER ASSEMBLY" ABSTRACT OF THE DISCLOSURE A straw chopper and spreader assembly for receiv- ing straw from a threshing machine, has a casing enclosing a pair of contra-rotatable flail assemblies. The flails are mounted in different horizontal planes and have blades which overlap so as to shear and chop the straw. At the rear of the casing is a rear outlet defined between a rear skirt and a bottom extension of the casing. The rear skirt is adjustable so as to enlarge or reduce the size of the rear outlet. In addition to discharge through the rear outlet, chopped straw is also discharged laterally through side chutes which have removable end portions so that discharge selectively may be outwardly and upwardly or outwardly and downwardly. Chaff spreading discs are mounted below the assembly and rotates horizontally. These receive chaff from the threshing combine via a reciprocating feed tray secured to and extending rearwardly from the reciprocal sieves and extend rearwardly from the sieve thereby deposit- ing chaff onto the discs to be spread outwardly with chopped straw. A beater assembly rotates just above and behind the discharge of the straw walker which, together with a de- flector panel, forces the straw downwardly into the flail assemblies.
