Abstract
A seeding implement such as a minimum tillage drill including a pair of trailing transport wheels located inwardly of the outermost ends of the implement frame, one of the wheels being a combination transport-drive wheel mounted on a pivoting wheel frame with a portion of the implement frame extending rearwardly over the wheel frame to act as a stop member for maintaining the trailing wheels in a generally level condition during transport but permitting the combination transport-drive wheel to rock downwardly and stay in ground contact when the openers lift the machine on uneven terrain or in hard ground conditions.
