  • Patent number: 7926248
    Abstract: A harvesting header having a flexible cutterbar assembly utilizes draper belts behind the cutterbar assembly to gently consolidate the severed crop materials and deliver them to a point of discharge and delivery, such as to the feederhouse of a combine harvester. The header includes laterally spaced support arms. The support arms are attached to the flexible cutterbar assembly and pivotally supported adjacent rear ends thereof for swinging movement about a laterally extending axis.

  • Publication number: 20020066264
    Abstract: A square baler has a generally horizontally disposed baling chamber, a reciprocating plunger within the chamber, and an underslung loading duct projecting downwardly and forwardly from the bottom of the chamber to a pickup apparatus. A stuffer is operable through successive stuffing strokes within the duct to both transfer material from the pickup apparatus into the baling chamber and precompress the material within the duct. The stuffer includes a pair of fore-and-aft mutually spaced apart forks presenting a leading fork and a trailing fork with respect to the direction of travel of the stuffer during a stuffing stroke. The leading fork has a generally kidney-shaped path of travel that begins its upstroke rearwardly of the forwardly facing inlet of the duct, while the trailing fork has a generally kidney-shaped path of travel that begins its upstroke forwardly of the inlet of the duct.

  • Patent number: 5368238
    Abstract: A horizontally oriented three sided frame is adapted to hold a round hay bale. An endless chain driven conveyor encircles the floor of the frame to cause the round bale to rotate about a longitudinal axis thereof while simultaneously urging a portion of the perimeter of the bale against a rotary drum cutter arrayed just above the floor on one side of the frame. The cutter chops the hay bale into individual strands for feeding to livestock. A spacer, commonly called a concave, is pivotably attached to the frame, and is spaced from and extends longitudinally along the top of the rotary drum. The spacing between the concave and the drum is adjustable. By adjusting this spacing, as well as the speed of rotation of the rotary drum and the speed of rotation of the round bale via the conveyor, the length of hay strands cut by the cutter is adjustable.

  • Patent number: 5161353
    Abstract: A mower vehicle includes a vehicle frame and single front and rear driven wheels. First and second blade housings are pivotally connected to each other along a longitudinal axis of the vehicle frame and are attached to first and second side frames, respectively. Each side frame is pivotally attached to the vehicle frame near the rear thereof with a hydraulically retractable and extendable cylinder assembly urging each side frame downward or upward in response to changes automatically sensed in the slope of the terrain. Ground engaging outrigger wheels attached to each side frame contact the terrain and the vehicle frame is thus maintained in a generally upright position.
