| 81 | Seed Boot For Double-Shoot Disc Opener | US12493791 | 2009-06-29 | US20100107941A1 | 2010-05-06 | Robin B. Schilling; Matthew S. Naylor; Dennis W. Chahley |
| A planting unit for depositing fertilizer and seed in a single pass, double shoot manner includes a rotating disc that cuts a furrow in a planting surface and a trailing seed boot, having a cutting edge, that cuts a vertically and horizontally offset trench in the furrow to form a seed bed in the planting surface. The disc has a mounting frame for mounting the disc to a linkage assembly that is, in turn, coupled to a toolbar mount. The seed boot is also attached to the mounting frame. This common attachment provides a relatively short and compact device without sacrificing fertilizer and seed stratification. | ||||||

| A disk blade scraper is used with a tillage implement having rotating disk blades separated by hub spools. In one form, the disk blade scraper has a wide tapered scraper blade positioned very close to the transition of the hub spool and the disk blade. In another form, the disk blade scraper incorporates a round disk having an edge that runs in the transition joint of the disk blade and the hub spool. In yet another form, the disk blade scraper incorporates a round and or square bar that is positioned in such a way that the bar end rubs against this transition joint. In still another form, the disk blade scraper incorporates a flat scraper blade shaped to fit the contour of the backside of the disk blade. The corner of this scraper is positioned very close to the transition joint of the disk blade and the hub spool. | ||||||

| 85 | Fertilizer coulter with trash-shedding, vibratory cleaning time | US10185625 | 2002-06-28 | US06698528B2 | 2004-03-02 | Donald T. Best; Dale S. Ryczak; John A. Lesanko; Murray K. Just |
| A coulter assembly has a resilient spring tine that bears against the compression face of the angled coulter during field operations to remove dirt clumps that otherwise inhibit the furrow-forming action of the coulter. A special spring coil mounting of the tine provides a lively vibratory action as the tine encounters various impact loads from different directions during field operations, thus rendering the tine essentially self-cleaning insofar as trash accumulations are concerned. The angle of attack of the tine relative to the ground and the coulter can be readily adjusted without diminishing the vibratory action of the tine. | ||||||

| 88 | Cleaner for tined wheels | US187211 | 1994-01-25 | US5507351A | 1996-04-16 | Howard Martin |
| 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. | ||||||

| 92 | Disk harrow standard for support beams of different cross sections | US208693 | 1988-06-20 | US4842077A | 1989-06-27 | Willard E. Peterson, Jr.; James F. Bierl |
| A disk bearing standard which may be utilized with support tubes of different cross sections by simply changing a low cost U-bolt which clamps the standard to the tube. The standard includes front and lower locating surfaces formed at an angle of ninety degrees with respect to each other. A bolt-receiving member angles upwardly from the forward surface at an angle of about forty-five degrees and receives an angled leg of the U-bolt. The rear leg of the U-bolt extends downwardly through an elongated slot at the aft end of the lower locating surface. The size of the U-bolt is selected according to the size of the mounting tube, and the U-bolt clamps the standard in two planes perpendicular to each other to prevent misalignment of the standard when loads are applied. A rearwardly extending appendage provides a scraper tube mounting which is fixed with respect to the center line of the disk blades regardless of the selected size of the mounting tube. | ||||||

| 94 | High-speed agricultural disc | US810124 | 1977-06-27 | US4098349A | 1978-07-04 | Atiq A. Jilani |
| By providing a circular, dished agricultural disc with peripheral W-shaped notches, a small tooth being formed at the center of each notch, the disc may be operated at relatively high speeds while still achieving vigorous cutting, stirring and mixing of the soil. At the same time, excessive throwing of soil is avoided, thereby preventing soil accumulation into high ridges with wide intervening furrows. | ||||||
| 95 | Scraper assembly for ground tillage implement discs | US566725 | 1975-04-10 | US4008770A | 1977-02-22 | James A. Boone; Dennis L. Lewallen; Harold G. Walker |
| This invention relates to an improved scraper assembly for the discs of ground tillage implements which is characterized by a mounting bracket fastenable onto the implement frame, an inverted generally L-shaped hanger subassembly carried by the mounting bracket for pendulous pivotal movement about an axis defined by the horizontally-disposed leg of said subassembly, a blade-carrying shaft mounted for rotational movement in the downwardly-opening vertically-disposed leg of the L-shaped subassembly, the latter element defining a self-cleaning housing therefor, biasing means connected between the bracket and hanger subassembly normally biasing the scraper blade housed therein against the concave face of the adjacent disc, an oversize annular groove in the shaft to which the blade is attached located inside the housing defined by the downwardly-opening tubular element of the hanger subassembly, a pin carried by said tubular element in tangential relation to the bottom of the annular groove within the shaft, and a ball-type thrust bearing at the upper closed end of the tubular element effective to absorb the thrust loads imposed upon the blade shaft while, at the same time, preventing the pin from touching the sides of the groove when under load. | ||||||
| 96 | Spring biased scraper for disk implements | US30213972 | 1972-10-30 | US3833067A | 1974-09-03 | PETERSON W; YOUNGBERG C |
| Scraper apparatus for the soil engaging disks on a disk implement, the apparatus including a plurality of scraper arms, one for each disk, pivotally mounted at their upper ends on a support member for movement of their lower ends toward and away from their associated disks. The support member is adjustably mounted on the implement frame to afford common adjustment of the scraper arms radially with respect to the disks. A scraper blade is mounted on the cylindrical lower end of each arm by means of a U-shaped bracket extending through an aperture in the blade and rotatably receiving the lower end of the arm, the bracket having a pair of outwardly flanged legs engageable with the blade to limit movement of the blade radially relative to the arm, and the arm having a stop pin engageable with the edges of a circumferential slot in the bracket to limit axial movement of the blade relative to the arm. Each scraper arm includes an upper and lower spring anchor disposed above and below, respectively, the axis of the pivotal connection of the arm and support, each anchor having a plurality of spring anchor points thereon disposed at varying radial distances from the pivot axis. A spring connects the lower anchor on one of the arms with the upper anchor on the immediately adjacent arm to bias the scraper blades on the lower ends of both arms toward their respective disks, the spring being adjustable on the spring anchor points to vary the force of the blades against the disks.
