ABSTRACT:
A compact row unit positioning structure includes a gear and mating toothed surface to positively position agricultural row units on an implement. An electric or hydraulic motor may be used to drive the gear and move row units individually or in groups to change row spacings, follow rows or move row units to a maintenance position. In one embodiment, position sensing structure such a row finder or GPS device connected to a controller operates the positioning structure. Automatic on-the-go row alignment may be implemented, and various row spacings, skip-row patterns or repair access positions may be provided either manually or automatically.
