Abstract: An improved snap-on height adjustment spacer clip is provided for height adjustment of wheeled frames including at least one ground-engageable wheel assembly. The snap-on clip includes a pair of mutually opposed, resiliently spreadable arms integrally connected at one end and disconnected at the opposite end. The clip arms are sized for embracing the spindle portion of the wheel assembly when installed, and are sized to permit the arms to yieldably flex toward and away from one another as the spindle passes transversely between the arms during installation and removal of the clip. The clip preferably includes a pair of mutually opposed, resiliently compressible hand knobs for use in clip installation and removal.

Abstract: A powered rake for windrowing debris for subsequent collection is provided which includes a main frame for coupling to a tractor, a subframe mounted for pivotal movement relative to the main frame about an upright pivot axis, a roller pivotal with the subframe to an oblique angle relative to the direction of travel, and a material control member including a blade extending along the length of the roller and presenting a gap therebetween. The subframe is preferably pivotal for presenting the roller at an oblique angle to the right or left with respect to the intended direction of travel, thereby permitting the powered rake hereof to continuously windrow the debris in the path of the roller. The roller is rotatably mounted on a pair of downwardly and forwardly extending legs which present substantially open areas outboard of the roller to permit debris to pass freely outboard into a windrow without any obstruction from the frame or subframe supporting the roller.

Abstract: A rasp bar assembly for a threshing cylinder includes a single backing plate for carrying a plurality of rasp bars thereacross. The rasp bars are separated by a region of discontinuity for allowing the backing plate to flex without breaking the rasp bars attached thereto. Each of the rasp bars are provided with a toothed surface and a mounting surface, a front edge and a back edge, and at least one end which is angled obliquely to the front and back edge and parallel to the teeth.
