Patent number: 6684963Abstract: Sweep retaining structure includes a retainer having a contact end biased towards the sweep. The sweep includes two or more spaced end-receiving areas to accommodate changes in the mounted sweep position. In one embodiment, the retainer is a wire made of spring steel having a contact end biased against the underside of the sweep. In one embodiment, the underside of the sweep includes a series of stepped portions. As the sweep is forced on the adapter on the shank, the contact end springs into retaining position on the stepped portion that aligns with the spring end when the sweep is in the mounted position. The sweep can be attached loosely by hand in an initial position with operating forces moving the sweep to a wedge locked position.Type: GrantFiled: October 10, 2002Date of Patent: February 3, 2004Assignee: Deere & CompanyInventors: Benoit Jocelyn Poutre, Richard Wayne Hook, James Thomas Noonan, Donald Ray Peck, Michael Sieben Egert

Patent number: 6668940Abstract: A cultivator point assembly includes an adaptor having a front and a rear end, and intended to be mounted to a cultivator machine at an upper end and having a foot projecting from a lower end. A cultivator point is adapted to be engaged with the adaptor and has a mounting section and a forward ground-working edge. An aperture in the mounting section is adapted to receive the foot of the adaptor in a first reversed position, whereafter the cultivator point is rotated 180° relative to the adaptor into an intermediate position in which the ground working edge is in a forward facing position relative to the adaptor, and is then moved rearwardly relative to the adaptor into a working position. A stop in use prevents unintentional detachment of the cultivator point from the adaptor.Type: GrantFiled: August 20, 2001Date of Patent: December 30, 2003Inventor: Austin Timothy Ryan

Publication number: 20030150628Abstract: Sweep retaining structure includes a spring wire retainer with a base supported in a groove on the underside of the wedge support which mates with a stem portion of the sweep. The wedge support is apertured, and a central curved portion of the retainer passes through the aperture and supports a sweep-contacting end above the surface of the wedge support. The end is biased toward a contact area on the sweep to engage the area and eliminate sweep loss problems by preventing the sweep from slipping downwardly from the mounted position. To remove the sweep, a tool is inserted through the slot to depress the retainer end, and the sweep is forced off the wedge support. A raised area on the sweep directs soil away from the retainer and contact area to reduce wear and eliminate depression of the end during operation. The underside of the raised area positions the wire end and provides bend-resisting support for the wire.Type: ApplicationFiled: February 28, 2003Publication date: August 14, 2003Inventors: Richard David Zaun, Benoit Poutre, Donald Ray Peck, Mark Beeck, Richard Wayne Hook, James Michael VanAuwelaer, Jarrod Ray Ruckle

Patent number: 6571884Abstract: A novel solution for changing sweeps or knives on a cultivator or other soil working tool is the subject matter of the present invention. In today's farming world, where labor is at a premium and time is of the essence, a sole operator or farmer in preparing the fields for planting, summer fallow or other operations will sometimes need to change the sweeps or knives which till the ground several times for different crops or operations. The novel invention herein provides for an apparatus for quickly removing the sweeps (2) on cultivator shanks and replacing them with other soil openers of different width or configuration. A simple press button (7) releases the sweep (2) from an adapter bolted to a standard cultivator shank. The present invention eliminates the problem of sweeps falling off shanks due to lack of friction or difficulty in removing sweeps because of over friction.Type: GrantFiled: April 4, 2002Date of Patent: June 3, 2003Assignee: F.

Patent number: 6516895Abstract: A mounting assembly for a shank including a shank holder having a passage for receiving the shank, the passage having at one end opposite tapering surfaces which define with the leading edge of the shank opposite tapering spaces for receiving wedge members. Bolts are provided between the wedging members and holder to urge the wedging members longitudinally of the passage to wedge the shank in a selected position relative to the holder.Type: GrantFiled: February 15, 2001Date of Patent: February 11, 2003Inventor: Allan James Yeomans

Patent number: 6505688Abstract: A seed bed packer including a frame, a plurality of wheels connected to the frame, and a soil packing element. The packer also includes a spring shank for transferring weight from the frame to the soil packing element. The spring shank includes a first leg connected to the frame and a second leg connected to the soil packing element. When weight is transferred through the spring shank to the packing element, the first and second legs flex toward one another. The spring shanks are capable of distributing the weight of the frame between the wheels and the packing element, while concurrently providing sufficient flexibility to allow the packing element generally uniformly pack the soil, even over rough terrain.Type: GrantFiled: September 6, 2000Date of Patent: January 14, 2003Assignee: Summers Manufacturing Co., Inc.Inventor: Peter D.
