  • Patent number: 6062010
    Abstract: Self propelled harvesting apparatus is disclosed for processing plant material. The apparatus comprises a pair of cylindrical crushing rolls for crushing plant material and a rotor with radial fins operably associated with the rolls for impacting the crushed plant material. A hood is associated with the impact rotor for redirecting impacted plant material back to the rotor for reimpacting the plant material and to provide severely conditioned plant material. A press assembly presses the severely conditioned plant material and subsequently discharges a cohesive mat of compressed plant material from the harvesting apparatus onto the stubble in the field over which the apparatus is being operated.
    Type: Grant
    Filed: August 3, 1998
    Date of Patent: May 16, 2000

  • Patent number: 5894716
    Abstract: Apparatus for processing plant material in which a first rotatable crushing roller with an outer generally cylindrical surface cooperates with a second adjacent rotatable crushing roller also having an outer generally cylindrical surface. The rollers, mounted with their surfaces positioned in close proximity to each other, rotate in opposite directions to receive and crush plant material. A unique rotatable impact rotor having a plurality of outwardly extending projections is mounted rearwardly of the crushing rollers for impacting plant material that has passed between the rollers to macerate the plant material that has been previously crushed by the rollers. The crushed and macerated plant material is diverted and again impacted one or more times by the outwardly extending projections of the impact rotor after which it is deflected in rearward path by a variably positioned baffle.

  • Patent number: 4411127
    Abstract: A windguard for use on the pick-up mechanism of a crop harvesting machine. The windguard automatically adjusts to varying sizes of windrows of crop material as the machine and its pick-up mechanism are being operated. The windguard has an unlimited number of adjustment positions for different sizes of windrows.

  • Patent number: 4385484
    Abstract: A crop harvesting machine having a disc cutterbar is disclosed wherein the shields covering each individual disc cutter unit are connected to a transverse rotatable shaft so that the shields can be pivotally moved between a lowered operative position immediately above the disc cutter unit and a raised inoperative position, wherein convenient access can be had to the disc cutterbar for service and maintenance thereof. The shields are connected to the shaft by mounting tabs having a downwardly depending leg that engages a stop on the header frame to prevent the shields from lowering into a position that would interfere with the rotative operation of the disc cutters. A spring-loaded pin and bracket control mechanism is also provided to selectively lock the shields in either the lowered or raised position by controlling the rotative position of the shaft.
