The wheel arms of a planter row unit are mounted to the row unit frame for independent pivotal motion. The ends of a saddle link are received in sockets formed on gauge wheel arms; and a yoke (or ring-shaped link) pivotally mounted to the frame engages a central saddle bearing surface on the saddle link. The wheel arms, saddle link and yoke are constructed and arranged such that when one gauge wheel raises when it encounters an obstruction, the other lowers and the frame raises by about one-half the distance which the first gauge wheel is raised.
