The frame arms have mounted thereto harrow sections containing harrow teeth for ground working. A spring member, in cooperation with bracket members, introduces variable degrees of pressure to the frame arms resulting in the capability to regulate the ultimate downward pressure exerted by the harrow teeth on the underlying terrain. When desired, the frame arms are raised and maintained, through an over-center arrangement, at elevations disengaging the harrow teeth from terrain contact.

Abstract: An implement preferably has elongated, stationary beams that extend horizontally transverse to the normal direction of travel. Staggered soil cultivating rotors are fastened to the beams at spaced apart locations and are ground driven to work closely adjacent strips of soil or a single broad path. Each rotor is freely rotatable about an upwardly extending shaft and has downwardly extending soil working members, such as tines, with lower active portions. Each active portion can have a lower outwardly directed part that, during rotation, describes a circle having a radius about equal to or less than the length of the active portion. The outwardly directed tine part increases ground contact and improves rotation. The rotors can be mounted in pairs; the rotors of each pair being angled from the vertical so that they rotate in opposite directions from one another.

Abstract: An earth-working tool has mounting means at one end for attachment of the tool to the frame of an agricultural implement, a tool blade down the forward edge of the tool and attachment means at the other end of the tool for securing a tool point. The mounting means is so arranged that the tool may be attached to the frame in such a manner that the tool blade will form a rearward angle, from the top end to the other end, in relation to a line normal to the direction of forward movement which the tool will take during use, with the result that soil tilled by the tool point will be prevented from rising to the surface by the action of the rearwardly directed tool blade. Ideally the tool may be mounted so that the tool blade will be forwardly directed, either by reversing the tool or by providing alternative mounting holes for mounting the tool to an agricultural implement.
