ABSTRACT:
A soil cultivating implement, such as a rotary plow has soil working members mounted to revolve about an axis that extends transverse to the direction of travel. The soil working members can be tines or blades that are positioned to enter the soil in unison, lift sliced portions of soil and deposit same on the ground to the rear of the plow. The soil working members are mounted in offset relationship at locations about the axis of rotation to minimize "drag and snatch." The soil working members can be turned in addition to being revolved about the axis of rotation as a part of a rotor and more than one row of soil working members can be mounted on the implement. Scrapers, stationary or movable, can be positioned to cooperate with the soil working members to shed the soil from these members.
