Abstract: A method and apparatus for tilling a field that includes a frame, a ground engaging tool attached to the frame wherein the ground engaging tool creates an initial residue flow pattern and a spike tooth linked to the fame and positioned approximately inline with the initial residue flow pattern, wherein the tooth alters the flow pattern of the residue.

Abstract: An auger coupler for a folding grain conveyor is disclosed which operates to connect an upper auger to a lower auger. A drive member adapted to be connected to the lower auger include a pilot shaft designed to help align the drive member with the driven member and an annular thrust bearing surface surrounding the pilot shaft. Spaced outwardly from the thrust bearing surface is an annular row of drive teeth. The drive teeth project axially upwardly from an annular base surface which is parallel to and concentric with the thrust bearing surface. A driven member adapted to be connected to the upper auger includes a receiver sized and shaped to accept the pilot shaft of the drive member. The receiver is also surrounded by an annular thrust bearing surface. Spaced radially outwardly from the thrust bearing surface is an annular row of driven teeth which are structurally identical to the drive teeth.

Abstract: Improved bearing assemblies for agricultural implements and in particular flexible frame towed agricultural implements such as plows and the like are disclosed. The bearing assemblies preferably include a bearing formed from ultra high molecular weight polyethylene. The improved bearing assembly includes a flanged cylindrical bearing sleeve adapted for use with a hinge connecting adjacent frame sections of a flexible frame towed agricultural implement. The flanged cylindrical bearing sleeve is positioned within an outer cylindrical metal bearing sleeve which is mounted in the end of a male hinge member in alignment with a pivot pin receiving bore extending therethrough. A pivot pin extending through the flanged cylindrical bearing sleeve connects a hinge clevis on a female hinge member to the male hinge member. A flange on the flanged cylindrical bearing sleeve extends between thrust bearing surfaces on the male hinge member and the female hinge member.

Abstract: A drafting structure for a multi-section implement having a plurality of interconnected implement sections arranged abreast to a line of draft includes a pair of spaced draft beams extended generally parallel to the line of draft and a pair of spaced spreader beams extended transversely thereto and forming a generally rectangular rigid frame. The frame is mounted over implement center sections and connected to wing sections thereof by hinges that enable folding of the implement for travel and, which when the implement is unfolded and in its working configuration, disperses and distributes the drafting forces and pressures that tend to cause arching of the center sections. Hitch arms are extended from the frame for connection to a prime mover.
