Abstract: Embodiments of the present apparatus comprise a land preparation apparatus that includes a rotatable drum, a plurality of tool holders arranged on the drum, wherein each tool holder comprises a first connection interface, a plurality of land preparation tools, wherein each land preparation tool is configured to connect with a tool holder and wherein each land preparation tool comprises a second connection interface, a plurality of removable connectors, wherein the connectors comprise a material different from that of the tool holders and the land preparation tools, wherein each connector is removable from the tool and the tool holder, and wherein each connector is configured to mate with a first connection interface of a tool holder and with a second connection interface of a land preparation tool. The apparatus further includes a land preparation vehicle comprising an attachment connection device configured to mate with the rotatable drum, wherein the vehicle is configured to drive the rotatable drum.

Abstract: An agricultural ground working apparatus includes a mounting bracket adapted for attachment to an implement frame. A shank is pivotally attached to the mounting bracket about a shank pivot axis and extends downward from the mounting bracket to a lower end thereof adapted for engaging the ground. Right and left disc arms are pivotally attached at upper portions thereof to the mounting bracket such that the disc arms pivot about arm pivot axes independent of the shank. The disc arms extend rearward and downward from the mounting bracket on each side of the shank, and right and left discs are rotatably attached to lower portions of the corresponding right and left disc arms.

Abstract: A mulching unit for a mulching apparatus includes at least one cutting assembly or hammer having a rotatable support element and two cutting elements spaced apart from one another by a predetermined gap that allows debris to pass between the cutting elements, thereby increasing efficiency and enabling higher rotating speeds for sustained amounts of time. The cutting elements include tips that may be formed in one piece with the support element, e.g., a collar, and the tips may be covered with a protective layer of tungsten and/or carbide. Alternatively, the tips themselves can be made from tungsten and/or carbide and physically attached, e.g., by welding, to the collar to form an integral unit. The cutting elements may be mounted on support element halves that can independently rotate on a support rod of the mulching unit.

Abstract: A lightweight device for obtaining improved performance of rubber tired vehicles. The arrangement has high-strength, thin-gauged traction intensifying means secured to the driving member for a tire, having a smooth or shallow tread, providing improved drawbar performance in fields when said traction intensifying means are engaged and improved traction and riding characteristics on hard grounds and pavements when said traction intensifying means are disengaged; and includes actuating means for rapid and convenient conversion between "steel-drive" for fields and "rubber-drive" for hard surfaces, and vice versa.

Abstract: A cultivating tool propelled by a walking attendant has sheet metal tines mounted on a rotating axle for rotation therewith. The tines are channel-shaped with axle-accommodating apertures through the flanges and also through the webs. When the axle is engaged through the flange apertures, the ends of the web engage the soil flatwise so as to provide a hoeing action; and when the axle is engaged through the web apertures, the ends of the web engage the soil edgewise so as to provide a chopping action.

Abstract: A cultivating implement has rows of rotatable soil working cultivating members that are mounted on beams extending transverse to the direction of travel, one behind the other. The members rotate about upwardly extending axes and can be positioned along the beams to cooperate with one another and work soil between rows of plants. Assemblies of crumbler-rollers are secured to the frame and positioned to engage soil worked by the cultivating members but avoid the plant rows. Each assembly is secured by a support arm adjustably settable along the length of a beam at the rear of the frame. Each assembly is a pair or two rollers journalled on a common shaft and each roller has two supports, one of which is movable along the shaft to and from the other to adjust the width of the roller. Each support mounts bars that form the periphery of the roller.
