Abstract
A row unit for a work vehicle includes a row unit frame, a gauge wheel, and a gauge wheel coupling assembly that attaches the gauge wheel to the row unit frame at a lateral position with respect to the row unit frame. The gauge wheel coupling assembly supports the gauge wheel for lateral movement to change the lateral position of the gauge wheel. The gauge wheel coupling assembly includes a course adjust coupling and a fine adjust coupling. The course adjust coupling is configured for selectively adjusting, at a first increment, the lateral position of the gauge wheel. The fine adjust coupling is configured for selectively adjusting, at a second increment, the lateral position of the gauge wheel. The first increment is larger than the second increment.
