Publication number: 20120312208Abstract: A method of seed planting in a “serpentine” pattern called the wave planter is demonstrated. It consists of a manner of placing the seeds that essentially results in equally spaced rows of seeds placed in a serpentine-like layout or wave instead of a straight row. The preferred method creates a wave pattern equidistant from the next, yet creates a substantial increase over the density of straight row planting devices and drills (e.g. parallel, essentially straight rows). The use of the wave pattern provide concrete and substantial benefits to the business and economics of farming through labor, energy, and maintenance savings over current planting methods which results in a new farming business method. The method may be accomplished by several devices. Some of the devices include an oscillating draw bar planter; oscillating tongue planter; elliptical row opener; steerable undercarriage for the planter and castor row openers under undercarriage.Type: ApplicationFiled: August 15, 2012Publication date: December 13, 2012Applicant: IDEAS, MARKETS AND MORE, INC.Inventors: Steven A.

Patent number: 4831945Abstract: Relatively simple opener assembly structure for maintaining a generally constant vertical relationship between an opener and a trailing press wheel. The structure provides benefits of a parallel linkage design but obviates the extra links of, and provides better trash shedding and tripping characteristics than, a parallel linkage design. An opener arm and a press wheel arm are pivotally connected to a leg assembly for rocking about offset pivotal axes. As the press wheel arm oscillates over uneven ground, the opener arm is constrained for vertical movement with the central portion of a press wheel arm by a track and follower assembly. The opener arm is substantially shorter than the press wheel arm and causes the opener to rotate both rearwardly and upwardly upon encountering trash or other obstacles.Type: GrantFiled: November 25, 1987Date of Patent: May 23, 1989Assignee: Deere & CompanyInventor: Lowell H. Neumeyer

Patent number: 4083412Abstract: An agricultural seed-drill comprises a frame and pivotally mounted drag bar carrying a coulter disc. An ovoid rubber spring is located between the drag bar and a member, such as a moving beam or bell crank lever, associated with the frame to apply pressure to the coulter, or to enable the coulter to be raised so that the disc does not contact the soil. In order to relieve strain on the spring member when the coulter is raised, the said spring member and associated threaded studs, used to attach the spring member to the drag arm and the member associated with the frame, contain a continuous longitudinal axial passageway in which is located a cable the end portions of which extend through the studs and are terminated by nipples spaced apart from the end of the studs. By this means the weight of the drag arm is taken by the cable when the drag arm is in the raised position.Type: GrantFiled: March 15, 1976Date of Patent: April 11, 1978Assignee: P.B.
