Abstract: A soil tilling device that is pulled by a tractor vehicle comprises at least one tool holder that is supported at a supporting element and is rotatably drivable. At least two circular disk-shaped soil tilling tools are connected to a respective one of the tool holders and are distributed over a circumference of the tool holder at a uniform distance from one another.

The members are mounted on a frame portion that is turntable about an axis extending transverse to the direction of travel, against resilient opposition.

Abstract: A soil cultivating implement has an elongated frame portion and a plurality of rotatable members mounted at the lower ends of respective elongated shafts. Each member includes a carrier and tools on radial arms are connected to the carrier. The carrier is fastened to a nonrotatable tube through a hood and flange arrangement that prevents stalks and the like from fouling the shaft housed within the tube. The tools can be rigid tines or resilient strip-like blades which are angled downwardly in the direction of rotation. Guides in the form of rods can be mounted to coextend with the tools, upwardly to the rear so that soil loosened by the tools is displaced upwardly by forces that crumble the displaced soil before the latter falls rearwardly. Drive to shafts is effected through a gear box on the frame portion and further shafts that have pinions in mesh with those on the soil working member shafts. A further implement can be linked to the frame portion and driven via a rear shaft of the gear box.

Each member has a horizontal central support, and an arm pivoted at each opposite end of the central support. A tine is fastened to the outer end of each arm and a soil working portion thereof extends down to work the soil upon rotation of the soil working members. A helical spring on each pivot extends to stops on the central support and the corresponding arm to bias that arm with tine to a forward operative position. Upon striking an obstacle, the tine and arm can pivot rearwardly and the spring urges same back to operative position when the obstacle is passed.

Abstract: A cultivator has driven soil working members mounted on corresponding upwardly extending shafts and each member includes a support with a hub secured near the lower end of a respective shaft. The support is formed from flat sheet material which define resilient arms that extend outwardly from the hub. Preferrably, the arms include two spaced apart parallel strips with a holder near the outer ends of the two strips. Fasteners, such as bolts, clamp the arms together and the strips of neighboring arms can be integral with one another. The arms and corresponding tines are thus deflectable in directions perpendicular to the planes of the strips.

Abstract: An implement has rotatable soil working members that include tines mounted on supports. Each support is formed by resilient interengaging strips that are clamped between an upper hub flange and a lower locking plate, the latter being connected to an upwardly extending driven shaft. The strips are bent to form rectilinear bases and outwardly extending arms of inner and outer pairs of strips. The outer ends of the arms are secured by respective upper and lower clamping plates which, together with the strip ends, form holders for tine fastening portions. When the soil working member is rotated about an axis defined by the shaft, the tines can deflect in directions tangential to the shaft and mitigate damage if any obstacle is encountered.

The tool or tine can be a torsioned spring steel strip or a rod that has a spring coil. Each tine can have one or more operative soil contacting ends that are spaced apart from one another. When the operative ends are located one above the other, the soil working member can work deep in the soil. The fastener can be a pin that extends horizontal and at right angles to the axis of rotation of the soil working member so that the operative ends can pivot to some extent about the fastener. The ends of each tool or tine can extend in different directions from one another and tines in pairs can be mounted on the same support. The support can include arms pivoted to the fastening portions of the tines by spaced apart pins.

A common transmission can be fixed to either respective gear box that rotates the members and the tools. In either arrangment, the transmission is connected to the driving gears for both the members and the tools which can be rotated at different speeds from that of the members. A ground engaging wheel can be positioned at either side of the center of the assembly to bear on ground that is located between neighboring tools and/or members. The member can work paths of soil having different widths from those of the tools.

The further tines can be of resilient, circular construction and connected to a holder by respective integral spring coils that are interconnected by a tie portion. The further tines and their coils are located at the upper and lower ends of the holder and secured to the holder by the same fastening that secures the rigid tine in that holder. The fastening can be a clamping plate and protective screen.
