ABSTRACT:
Track eliminator apparatus mountable on a tractor to be between the tractor and the grain box of a grain drill for breaking up the soil compacted by the tractor rear wheels. The track eliminator apparatus includes clamp members that are mounted on the tractor axle and pivotally mount draw arms. The draw arms mount left and right sub frames that are transversely adjustable connected by cross bars to provide a generally downwardly opening U-shaped space through which the grain drill tow bar is extended. Ground engaging spring teeth are mounted by the sub frames. A piston cylinder combination is connected between the tractor and one of the cross bars for moving the sub frames between a spring tooth ground engaging position and an elevated travel position.
