Abstract: A soil cultivator or harrow has a row of soil working members that are driven about upwardly extending axes to work the soil. A plant screen at each lateral side of the implement has a forward guide portion that is pivoted to the front of the frame and a rear, spring-biased portion that normally is held close to the implement's lateral sides. The guide portion of each screen is inclined with respect to the direction of travel to guide plants away from the soil working members during the forward travel of the implement. A pair of arms are pivoted adjacent their front ends to a forward portion of the main frame of the implement, and are connected at their rear ends by a transverse support. The arms are connected to the main frame intermediate their ends by a connection which permits angular adjustment of the arms about their pivots. Each end of the transverse support is connected to a further rearwardly and downwardly extending arm and a roller is supported between the further arms.

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.
