Row unit for work vehicle having gauge wheel with adjustable lateral position

A row unit for a work vehicle comprising:

• 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 supporting the gauge wheel for lateral movement to change the lateral position of the gauge wheel;
• the gauge wheel coupling assembly including a first member that is fixed to the row unit frame;
• the gauge wheel coupling assembly including a support arm that is attached to the wheel;
• the gauge wheel coupling assembly including a hub assembly;
• the gauge wheel coupling assembly including a course adjust coupling between the hub assembly and the first member;
• the gauge wheel coupling assembly including a fine adjust coupling between the support arm and the hub assembly;
• the course adjust coupling configured for selectively adjusting, at a first increment, the lateral position of the gauge wheel along an axis;
• the fine adjust coupling configured for selectively adjusting, at a second increment, the lateral position of the gauge wheel along the axis;
• and
• the first increment being larger than the second increment.

A work vehicle with at least one row unit comprising:

• 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 supporting the gauge wheel for lateral movement to change the lateral position of the gauge wheel;
• the gauge wheel coupling assembly including a shank that is fixed to and that extends laterally from the row unit frame, the shank including a plurality of first alignment apertures that are spaced apart along an axis of the shank;
• the gauge wheel coupling assembly having a support arm attached to the wheel;
• the gauge wheel coupling assembly including a hub assembly with a second alignment aperture;
• the gauge wheel coupling assembly including a course adjust coupling with an alignment pin that is received in the second alignment aperture and one of the first alignment apertures to retain the hub assembly in a fixed position along the axis;
• the gauge wheel coupling assembly including a threaded fine adjust coupling between the hub assembly and the support arm, the course adjust coupling configured for selectively adjusting, at a first increment, the lateral position of the gauge wheel;
• the fine adjust coupling configured for selectively adjusting, at a second increment, the lateral position of the gauge wheel;
• and
• the first increment being larger than the second increment.
