ABSTRACT:
A soil cultivator has at least one rotor mounted for rotation about a horizontal axis and rows of rigid soil working tines are secured on the rotor to be driven through the soil in a direction opposite to the travel direction of the cultivator. The tines can be curved with their free ends oriented to the rear with respect to their direction of movement through the soil. Stationary tines can be affixed in front of the rotor so that the rotor tines are moved between the stationary tines. Two rotors can be mounted side-by-side on a common shaft or axis of rotation and the shaft journalled in side plates having edge rims. A row of rotatable disc-like supporting members is arranged zig zag on a beam and the beam has arms that are adjustably connected to the cultivator frame at the rear of the rotor. Projections on the bottoms of the members induce rotation thereof. The rotor or rotors can also be supported by an elongated roller having a helical rib. The frame of the cultivator has a coupling member that can be offset with respect to the frame and an adjusting feature enables the implement to be positioned so that the rotor's axis of rotation is non perpendicular to the direction of travel.
