Abstract: A rotary cultivator has a row of soil working members mounted on upwardly extending shafts that are geared to a driving shaft extending transverse to the direction of travel. The shafts have soil working tools at their lower ends and transmission gears at their upper ends. Intermediate their ends, the shafts are surrounded by bearings in respective housings. The housings can be disconnected from their supports and the shaft, bearings and housing corresponding to each member can be removed or replaced as a unit. Upon removal, transmission gears are disengaged. The supports for the housings can be bars connected to spaced apart beams of the frame to which gear box - bearing housings are fastened by bolts. Alternatively, an enclosed casing can be formed by an assembly of three spaced apart plates that form an upper gear chamber and a lower trough within which the housings are secured. The rims of the plates can be clamped by bolts and the bearing housings bolted to the lower two plates.

Abstract: A cultivating implement has an elongated frame portion with a front three point coupling that connects to the three point lift of a conventional tractor. A rear supporting structure for a further implement has spaced apart beams that extend forward to pivots near the lower two points of the front coupling. The structure has interconnected frame beams that are supported on ground wheels and the rear ends of the forwardly extending beams are fixed to vertical frame beams. Rearwardly extending arms are pivoted to the interconnected frame beams and these arms together with coupling plates on an upper tie beam, form a rear three point coupling. The arms are interconnected to the remainder of the structure by adjustable carrier arms. Ground wheels support the structure and a further implement that is connected to the rear coupling.

Abstract: An implement has rotary soil-working cultivating members with tines that are arranged to work a broad path of soil.

A beamed support at the front of the implement frame has soil arresting elements fastened to the support and the elements can be tines, strips or the like that extend horizontally above the tines and below the main frame portion to free ends. The elements are positioned to arrest the lateral and/or forward displacement of soil thrown by the cultivating members. Soil crumbling members can also be attached to the frame portion in front of and between neighboring cultivating members. A supporting roller having a periphery formed by elongated rods is positioned to the rear of the cultivating members.

A protective and supporting member of elongated configuration is secured to the frame portion. The protective member can be nonrotatable but is angularly displaceable about a horizontal axis that extends generally parallel to the frame portion. The protective member has an inclined surface that can be curved or substantially flat and the outer surface faces the soil working members and is positioned relative to those members to direct debris downwardly to the ground. Stops on the frame portion and protective member limit the latter's movement relative to the remainder of the harrow.

An elongated soil crumbling member is pivoted to the frame portion at the front of that portion and settable to level the ground and provide support for the machine. A second elongated crumbling member is linked at the rear of the frame portion for free pivoting responsive to ground irregularities to further crumble the soil worked by the tined rotors. Both crumbling members have parallelogram linkage connections so that the relative positions of the crumbling members to the frame portion can vary without those members tilting. The bottoms of the crumbling members can be corrugated plates or other configured elements designed to bear on the ground and be self cleaning. Also, the rotors can have resilient or freely rotatable mountings to allow for the displacement of tines when meeting obstacles.

The two tines have respective arms of unequal lengths mounted on a hub that is journalled on the stub shaft and the tines are angled to trail with respect to the direction of driven rotation. This results in the arms being orientated in radial alignment from the soil working member's axis of rotation and the longer arm extending between that axis and the corresponding stub shaft.

Each working member is connected to a drive transmission to turn and, spaced apart soil working members mounted for free rotation about respective axes, are moved through the soil. At least two of the soil working members are different from one another and capable of workingthe soil in different ways. One member can be a group of tines that are freely rotatable about an upwardly extending axis and an adjacent member can be a disc that rotates about a horizontal axis. Each member includes a stub shaft that is journalled in a universal mount so that the members can be released and exchanged to meet varying soil conditions. The mount has a pivot connection and a setting device to retain the soil working member at various working angles. Also, the stud shaft is adjustable within a sleeve of the mount.
