Patent number: 5507351Abstract: This invention provides an improved apparatus for maintaining tooth rotating wheels, which are used to penetrate the soil either as a cultivating apparatus, a row cleaning apparatus, or as closing apparatus for row planters free of mulch, trash, dirt and/or rocks. By removing the debris from the space between the teeth on the wheel, the wheel can penetrate the soil to a controlled or desired depth as set by the operator. Debris between the wheels can limit the depth of penetration by the formation of a solid or semi-solid mass generally resembling of variable rim diameter. The wheels may be driven by a power mechanism or may be rotated by the penetration in the ground and the forward motion of a propulsion unit.The toothed wheel is kept clean of debris, thereby allowing accurate depth penetration as determined by conditions and requirements.Type: GrantFiled: January 25, 1994Date of Patent: April 16, 1996Inventor: Howard Martin

Patent number: 4603746Abstract: The present invention provides a scraper mechanism for a disk blade including a wear ring attached to the rim of a rotary scraper and releasably biased toward and held in planar contact with one side of a disk blade. The wear ring is molded from a low friction, long-wearing material, such as molded nylon. The low friction material eliminates the metal to metal contact of conventional rotary scrapers and therefore eliminates the squeal associated with rotary scrapers. Also, wear of the scraper is audibly detected when the wear ring is worn away, thereby alerting the operator that maintenance is required.Type: GrantFiled: July 19, 1984Date of Patent: August 5, 1986Inventor: Barton L. Swales

Patent number: 4009668Abstract: A method and apparatus for planting seeds. A V-shaped seed furrow having a predetermined depth is continuously formed while the soil adjacent each side of the furrow is uniformly firmed or compacted and a smooth surface formed. Seeds are continuously dispensed into the furrow. The walls of the furrow are then compacted about the seed as the furrow edges are collapsed over the seed to leave a comparatively non-compacted layer of soil above the seed. The planter is provided with a pair of furrow forming disks rotating about intersecting axes, a pair of gauge wheels rotatably supported rearwardly of the disk axes, each wheel being in close proximity to the outer surface of its respective disk, a seed dispensing means for delivering seed to the furrow, and a furrow closing device supported rearwardly of and in tracking relation to the gauge wheels.Type: GrantFiled: July 7, 1975Date of Patent: March 1, 1977Assignee: Deere & CompanyInventors: Ronald William Brass, Harold Valentine Hansen
