Abstract
A system for mounting row units on an agricultural implement suited for movement across a field. The mounting system comprises a row unit support frame connected to the agricultural implement. The row unit support frame includes a generally horizontal elongated bar on which the row units are individually mounted in laterally adjacent relation relative to each other and such that the row units are prevented from moving fore-and-aft relative to the frame. At least one of the row units is mounted for lateral movement along the bar and relative to the adjacent row unit. An actuator is provided for effecting powered lateral movement of the row unit along the length of the bar. Each actuator is operated under the influence of a sensor which monitors the lateral position of the respective row unit relative to a desirable path on the field and controls operation of the respective actuator to generally align the movable row unit relative to the desirable path. A method for supporting the row units on the bar for lateral movement is also disclosed.
