A row unit (118, 18) for a seeding machine. The row unit (118, 18) includes a frame (130, 14, 30), a first gauge wheel arm (166) pivotally coupled to the frame (130, 14, 30), a first gauge wheel (132) coupled to the first gauge wheel arm (166), a second gauge wheel arm (166) pivotally coupled to the frame (130, 14, 30), a second gauge wheel (132) coupled to the second gauge wheel arm (166), and a position sensor (148A, 148B, 148C, 148D, 148E, 148F, 148G, 148, 150) assembly having a position sensor (148A, 148B, 148C, 148D, 148E, 148F, 148G, 148, 150) at least partially disposed between the first gauge wheel arm (166) and the second gauge wheel arm (166) such that the position sensor (148A, 148B, 148C, 148D, 148E, 148F, 148G, 148, 150) is at least partially concealed from view between the first and second gauge wheels (132) when viewing the row unit (118, 18) along an axis of rotation (149) of the first gauge wheel (132).
