Abstract: An agricultural machine includes a disk blade assembly having a hub and a disk blade mounted to the hub. The hub has a perimeter. The disk blade is deflectable by ground forces in an area outside of the hub. A scraper assembly includes a mount, a scraper blade, and a hinge pivotally interconnecting the scraper blade with the mount. The hinge has an axis of rotation which passes through a point generally at or near a bottom of the hub perimeter, and generally coincident with the disk blade.

Abstract: A seed delivery device is positioned on the seed tube of a planter and between a pair of V-oriented opening disks. The device has an elongated duct having an upper end with an opening capable of being disposed in spatial communication with the seed tube. A lower end of the duct has an opening which is positioned directly behind and adjacent to the location where the pair of opening disks contact one another. The duct extends along a substantially straight line below the seed tube so that a seed traveling through the duct is directed in a substantially downward direction into a V-shaped trench. Structure is also provided for attaching the duct to the planter.

Abstract: A disk scraper assembly for a furrow opener including a pair of closely spaced disks rotatably mounted on a support in downwardly converging relation relative to each other. The scraper assembly includes a pair of scraper blades supported for lateral-sliding movement independently of and in opposite directions relative to each other between the disks of the furrow opener. Each blade has a generally planar configuration and includes an elongated scraper surface which is adjustably fitted and then fixedly held in place to scrape dirt from an inner face of one of the disks.

Abstract: The invention comprises an adjustable scraper device for scraping the disc blades of a grain drill. The device has a fixed mounting on the mounting for supporting the disc blades and a slidable mounting slidable along the fixed mounting to a selected adjusted position relative to the disc blade support mounting and the disc blades. Scrapers are mounted to the slidable mounting between the disc blades to be slid with the slidable mounting toward the center axis of the disc blades so that as the disc blade outer circumferential edge wears down, the scrapers, which act to scrape the disc blades, may be adjusted toward the center axis of the disc blades to keep the entire scraping portion of the scrapers within the confines of the outer circumferential edge of the disc blades, so that the scraping portion of the scraper will not wear on the outer edge of the disc blades and cause damage to the scraping portion of the scraper.

Abstract: An improved double disk scraper assembly having a pivot post projecting rearwardly from the principal vertical support, a first scraper with a first pivot end on the post and a second scraper with a second pivot end on the first pivot end. The first and second pivot ends are preferably sleeved members. The scrapers are each engaged with a disk under the direct force of a biasing means, preferably a coil spring, between them. The pivot independently within a limited range which serves to keep the biasing means in place. A seed tube passes vertically between the scrapers for seed deposition at a forward position.

Abstract: A rotary scraper for the exterior of planter disks which is mounted on a bracket easily attachable to existing grain planters. The rotary scrapers are mounted on the front edge of double disk planter disks vertically centered with the planter disks and with at least one half of the scraper disk outside the circumference of the planter disk.

Abstract: 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.

Abstract: A scraper assembly for a double disk furrow opener having a hinge bracket bolted rigidly to the cast boot assembly. Scrapers are supported by the hinge bracket and urged against the inside of the blades by a leaf spring. The bolt holds the relative position of the assembly to prevent the scrapers from overhanging the edge of the disk blades, and the leaf spring allows individual scraper action.

Abstract: A compact agricultural planter unit is provided for narrow row crops. The unit includes a pair of double disk furrow openers in combination with adjustable depth gauge wheels. The disks and wheels are carried by frame structure positioned between the wheels and are rotatably mounted on pivots located radially inwardly of the wheel peripheries. Manually adjustable structure for selecting the furrow depth or position of the gauge wheels relative to the disks extends slightly radially outwardly beyond the wheels.

Abstract: Seed sowing equipment is disclosed including a pair of cooperating disc blades mounted for rotation on an axle. A scraper is provided for cooperation with each of such blades for preventing the accumulation of soil on the inward side of such disc blades. The scraper includes a ring portion and a plurality of radially inwardly extending spokes terminating in a hub portion.
