ABSTRACT:
A base frame for a roll-over disc plow is symmetrical about a longitudinal axis and is adapted to be secured to a standard tractor hitch. A plow frame overlies and is pivoted to the base frame about the longitudinal axis. The plow frame is hydraulically moved about one hundred eighty degrees between extreme positions, in each instance lying against a respective one of a pair of steps effective to transmit forces between the towed base frame and a plow frame carrying two alternately used series of plow discs.
