Abstract: A row unit for a seeding implement features a coulter disc, an angularly variable link on which the disc is carried, a scraper body supported on the link, and a wing projecting laterally from an outer side of the scraper body. The scraper body is supported in an adjustable manner selectively repositionable into a plurality of differently pitched orientations, relative to the link, about a reference axis that transversely penetrates the disc plane. By adjusting the pitch angle of the scraper body in a local reference frame of the link, one can better achieve a proper effective working orientation of the wing for each of a plurality of differently angulated link positions, each of which corresponds to a different working depth of the row unit. Though this novel adjustability, winged scrapers previously limited to use on parallel link row units can now be effectively used on other row units.

Abstract: A multi-piece cutting edge attachment for a circular shaft of a harrow tine features a mounting member formed of a material that is weldable to, and distinct from, a first material of the harrow tine. A cutting edge member is formed of a third material that is harder than the first and second materials and less weldable to harrow tine than the second material of the mounting member. The cutting edge member has a front face and an opposing rear face that is conformingly shaped for placement against a front face of the mounting member at a lower end thereof. The multi-piece arrangement forms a cutting edge of greater hardness than that which is achievable by a material directly attachable to the tine itself.

Abstract: A composite working tool, for example a ground engaging tool of an agricultural implement, features a body composed of a first material and an insert composed of a distinct second material of greater hardness than the first material to define wear resistant surfaces of the tool. The tool body has an opening recessed thereinto from an exposed exterior surface fully surrounding the opening on all sides thereof, and the insert is attached to the body in a position at least partially received within the opening, for example by brazing. The increases the wear life of the body and provides greater mounting strength over surface-mounted wear inserts of the prior art.
