Abstract
An agricultural row crop planter is disclosed which includes a frame and a plurality of individual row units mounted to the frame. Some of the row units are mounted in front of the frame to be driven or pushed by it. The remaining units are mounted behind the frame and are pulled by it. Driven and pulled row units are arranged to plant alternate crop rows so the 'on center' lateral spacing of row units is much greater than if all units were mounted side-by-side as is conventional. The driven row units are foreshortened and have their frames strengthened to withstand the forces encountered in use, particularly on curves. The arrangement enables the farmer to plant more than one crop with the same planter and without adjusting the spacing of row units. It also permits the manufacturer to provide a wide range of row spacing, including a very narrow one, with the same planter frame and row units while providing greater trash clearance.
