  • Patent number: 4892504
    Abstract: A straw chopper and spreader assembly for receiving 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 adjustble 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.

  • Patent number: 4366664
    Abstract: A drive system for a pull-type swather or windrower in which a sensing device senses the side-draft of the swather under operating conditions. The sensing device indicates to a compensating device which is operable from the sensing device whether to increase, decrease or leave unchanged the rotational speed of drive wheels which are provided on the swather and powered by a power plant. The drive wheels act to keep the swather in an effective cutting position substantially transverse to the longitudinal axis of the tractor.
