摘要：
A row unit (118, 18) for a seeding machine. The row unit (118, 18) includes a frame (130, 14, 30), a gauge wheel arm (166) pivotally coupled to the frame (130, 14, 30), a gauge wheel (132) coupled to the gauge wheel arm (166), and a position sensor (148A, 148B, 148C, 148D, 148E, 148F, 148G, 148, 150) assembly configured to detect a gap (258) corresponding to a rotational position of the gauge wheel arm (166). The position sensor (148A, 148B, 148C, 148D, 148E, 148F, 148G, 148, 150) assembly includes a sensing target surface (246, 260). The sensing target surface (246, 260) is at least one of an eccentric surface or a cam surface.
