摘要： An agricultural seed meter is disclosed including a seed selection mechanism in the form of a belt or a drum having pockets and moving through a seed reservoir area for loading seeds into the pocket. A cut-off brush is movable between a singulating position and a volume metering position so that the meter may be used either as a singulating meter or for volume metering without changing, deleting parts or adding parts. In either mode, seed release is accurate and repeatable through the use of a retainer brush for holding the seeds in their associated pocket until the pocket, in a downward, curving path, passed beyond the end of the retainer brush, thereby releasing the seeds into a discharge conduit.

摘要： A wheel for belted track vehicles includes a hub with an upright central disc. A series of individually cast and machined segments are mounted to the disc in side-by-side relation about the periphery of both sides of the disc. Each segment takes the shape of a truncated sector having a general “L” shape as viewed from an end, with a back or base engaging a side of the disc, and belt support elements extending laterally of the disc for engaging and supporting the track.
