Patent number: 5921071Abstract: An agricultural harvesting machine, such as a forage harvester, comprises a feeder means for feeding crop material to crop processing means and a feeder arrest means for immediately arresting at least a portion of said feeder means upon detection of a foreign object. Said arrest means comprises a ratchet wheel mounted onto the drive line of said feeder means and an electrical actuator means for loading a pawl into engagement with said ratchet wheel.The harvesting machine comprises a means for automatically monitoring the good operative condition of the electrical actuator means and the means for generating an alarm signal upon detection of a bad operative condition by said monitoring means. The monitoring means checks the condition of the electrical actuator and its circuitry by applying a voltage thereto during a short interval and monitoring the response during or immediately after said interval. The length of this short interval is chosen to preclude actual engagement of the pawl.Type: GrantFiled: July 25, 1997Date of Patent: July 13, 1999Assignee: New Holland North America, Inc.Inventors: Bert J.F.

Patent number: 5904033Abstract: A vine cutter for cutting entangled vines of potato plants in front of a potato harvester so that the vines do not become entangled and accumulated upon a front portion of the potato harvester. The inventive device includes a frame having a pair of upper members and a pair of opposing lower members, a first disc journaled to the frame, a second disc journaled to the frame below the first disc and having a ground engaging rim attached coaxially, and a motor mechanically connected to the first and second discs. The first disc and the second disc are vertically orientated, and a portion of the discs overlap and are juxtaposed to one another. The pair of discs preferably include a plurality of notches projecting into their respective outer perimeters. The discs rotate at a differential to one another from 1.2 to 2.5 depending upon the type of vines being cut. The ground engaging ring attached to the second disc determines the depth of penetration by the second disc into the ground.Type: GrantFiled: July 2, 1997Date of Patent: May 18, 1999Inventor: Marvin J.

Patent number: 5901541Abstract: A windrower (1) useful for collecting stalk material from a field (43) and depositing the material In a windrow (61). The collection of dust and debris in the windrow is minimized by the use of a screen (24) located above the auger (29) which transports the cut stalk material to a discharge chute (14). The screen (24) permits lighter airborne particles to escape from the region surrounding the auger (29) before they are entrained and deposited into the windrow. A screen (47) is also placed beneath the auger (29) to permit small, dense particles to fall from the region surrounding the auger and be deposited on the ground (43). A flexible barrier (48) is placed between the auger and the cutting assembly (32) so that material falling through the screen is not reintroduced to the cutting blades (39, 42). A second barrier (64) is positioned behind the auger so as to form a volume (66) within which material is confined so that it will not become airborne.Type: GrantFiled: April 30, 1997Date of Patent: May 11, 1999Inventor: Dale Lindquist

Patent number: 5806293Abstract: A mower and/or aerating device (7) exhibits a mower drum and/or aerating drum (8) rotating around a horizontal axis running perpendicular to the mower and/or aerating device advance direction. The mower drum and/or aerating drum (8) feeds cut material and/or material removed from ground to a transverse transport worm (16) rotating around a rotation axis running parallel to the aerating drum (8). The transverse transport worm (16) is disposed in a transport trough (15). A longitudinal transport worm (17) adjoins in the middle region of the transverse transport worm (16) at an angle of 90.degree. relative to an axis of the transverse transport worm (16). A transfer element (21) is disposed at the transport trough (15), which transfer element (21) separates the mower drum and/or aerating drum (8) and the transverse transport worm (16). The transfer element (21) is disposed such that the material from the mower drum and/or aerating drum (8) is at least nearly completely thrown into the transport trough (15).Type: GrantFiled: July 30, 1996Date of Patent: September 15, 1998Assignee: Amazone Machines Agricoles S.A.Inventors: Laurent Klein, Wilfried Schomaker, Thomas Pfisterer

Patent number: 5660034Abstract: A foldable root crop defoliator wherein the implement has a central frame with lateral wings pivotally attached to the central frame. The front end of the central frame is adjustably attached to a hitch for towing the defoliator. Plant top cutting and shredding devices are mounted to the wing frames and are driven by a power train connected to the power-take-off (PTO) of the towing vehicle. In a use orientation, the two lateral wings are independently adjustable relative to the ground. Also, they have a range of free motion, and are able to "float" independently over the ground that they are immediately above. For a travel or storage orientation, each lateral wing is rotated upward to a vertical position by actuating a lifting device mounted on the central frame. The lifting device includes, for example, a piston and cylinder, and toggle linkage assembly. By being foldable, the defoliator may be reduced to a much smaller width, making it safer to transport and easier to store.Type: GrantFiled: September 12, 1995Date of Patent: August 26, 1997Assignee: WEC CompanyInventors: Don Gates, David R.
