ABSTRACT:
A cultivating implement has one or more forward cultivating rotors that are driven to work the top soil. During this working, stones and debris are unearthed. At the rear of the cultivating members, one or more rows of soil working members are moved through the soil and these members are soil engaging members with edges that contact the stones and push the stones down into the subsoil. The soil engaging members can be discs with edges having projections and the discs can be driven to rotate in the same or opposite direction as the rotor. Alternatively, the soil engaging members can be bars that extend down into the soil. In either case, a sieve of rods or bars can be positioned behind the rotor to allow fine soil to pass while stones are guided downwardly in front of the fine soil. The lower ends of the soil engaging members can be interconnected with a horizontal shaft on which the discs are mounted. A protective hood overlies the rotor as well as the soil engaging discs or bars. Adjustable arms interconnect one or more rows of the discs to the frame and the rows of discs can be moved vertically relative to the remainder of the implement on these arms.
