Abstract: An earthworking implement mounted on a three point hitch of a tractor for tilling compacted soil behind the drive wheels of the tractor. The implement has a transverse main frame including an inverted U-shaped central section carrying outwardly extended beams. Tool bars are adjustably mounted on the beams and carry earthworking tools that till the packed soil in the tracks made by the tractor wheels. The center portion of the frame is open to allow a forwardly directed tongue of a second implement, as a seed drill, to be connected to the draw bar of the tractor.
