Patent number: 6520100Abstract: A twin row planter (10) includes planting units (20a-26b) arranged in pairs (20-26). Each pair (20-26) is configured and positioned for planting two rows (78,80) of seeds less than about ten inches apart to produce two rows of crops in order to increase the yield of the plot. With this spacing, the rows (78,80) in each pair are close enough to simulate a single row enabling the use of a conventional cultivator, sprayer or harvesting machine.Type: GrantFiled: August 27, 2001Date of Patent: February 18, 2003Assignee: ATIInventors: Steven Maurice Spooner, Sr., Paul Barrett Wood, Eric Thomas Jorgensen

Patent number: 6443079Abstract: An agricultural machine has a movable rack (10) having at least one main wheel (16, 18), a hitch (12) which is arranged on the rack (10), a reservoir container (14) which is carried by the rack (10) and/or the hitch (12), and an agricultural implement (20) which is attached to the rack (10) at the rear in the direction of travel and has a plurality of rear support wheels (28). The machine is developed to the effect that the at least one main wheel (16, 18) is positively steered as a function of the pulling direction of a traction force which is exerted on the hitch (12). Such a machine is particularly compact and maneuverable even when the reservoir container is large.Type: GrantFiled: April 21, 2000Date of Patent: September 3, 2002Assignee: Horsch Maschinen GmbHInventor: Michael Horsch

Patent number: 6378621Abstract: A lift and rotate agricultural implement frame comprises a main frame having a lift tube and a carrier frame slidably mounted to the lift tube. The lift tube comprises a vertically extending main support tube having planar surfaces and a corrosion resistant exterior sleeve. The corrosion resistant exterior sleeve comprises corrosion resistant plates corresponding to the planar surfaces of the main support tube. Each of the plates has an interior surface and an exterior surface. At least one of the corrosion resistant plates adjoins another plate. One of the adjoining plates is provided with an overhang that extends past the exterior surface of the other plate of the pair. The plates are fillet welded to one another between the overhang and the other plate. The plates are also provided with oblong openings having oblong edges. The oblong edges are fillet welded to the main support tube to couple the sleeve to the main support tube.Type: GrantFiled: August 28, 2000Date of Patent: April 30, 2002Assignee: Deere & CompanyInventors: William Douglas Graham, Scott Charles McCartney, William Howard Smith, Patrick M.

Patent number: 6237696Abstract: A ground opener unit for a seeding or planting unit includes an arm attachable to an implement frame and a disc rotatably mounted to the arm for forming a furrow in the ground. A scraper assembly includes a scraper plate defining a scraper edge for contacting and scraping a surface of the disc. The scraper plate defines a mounting region remote from the edge. A scraper plate mount secures the scraper plate adjacent the disc and a resilient pad of material is interposed between the plate mounting region and the scraper plate mount. A spaced pair of fasteners extend through the mounting region to secure the scraper plate and resilient pad to the scraper plate mount. The fasteners are located in selected positions in the mounting region relative to the resilient pad such that the scraper plate is capable of being tilted or rocked when said scraper edge encounters irregularities thus assisting the scraper edge to follow the disc surface during use.Type: GrantFiled: October 20, 1999Date of Patent: May 29, 2001Assignee: Flexi-Coil Ltd.Inventor: Dean J.
