A cultivator can have a frame with a tow assembly so that the cultivator can be towed by a tractor. A cultivating assembly can be pivotally attached to the rear of the frame. The cultivating assembly can have a plurality of discs that engage and penetrate the soil beneath the cultivating assembly. The cultivating assembly can have a center section pivotally connected to the rear end of the frame, a first wing section pivotally connected to one side of the center section, a second wing pivotally connected to the other side of center section where all the sections have discs connected to them. A pair of ground wheels can be connected to the center section so that the ground wheels are positioned in front of the cultivating assembly when it is being used to cultivate a field.

An agricultural tool element (3) comprises a non-inflated tire (9) with a tread (9-1) and a pair of sidewalls (9-2) each connected to the tread (9-1) at a respective first end portion. The element (3) additionally comprises a rigid, generally annular base (7), by means of which the tire (9, 103) is fitted on a rotary support (2, 101) of an agricultural tool. The sidewalls (9-2) are each over-molded on a peripheral portion of the rigid base (7, 107) at a second end portion, opposite the tread (9-1).

An agricultural tillage implement is provided with a soil finishing system that includes a multi-bar harrow and a down pressure-controlled finishing tool that are arranged with respect to each other to enhance soil tilth and leveling, including reducing residual shank grooves in tilled soil, to improve seed bed preparation.

A spiker roller having (i) a roller assembly having a plurality of roller components each having a peripheral wall and a plurality of apertures in each wall and a centrally located hub or boss surrounding an opening; (ii) a multiplicity of spikes which are each releasably retained within a respective aperture of each roller component; and (iii) a support shaft which is insertable through each of the openings of each roller component wherein in operation each of the roller components rotate independently of each other.

An apparatus for use in a rolling basket of a tillage implement, the rolling basket comprising a plurality of elongated bars or blades spaced apart around a plurality of spaced apart rings, the bars or blades attached to the spaced apart rings, the apparatus includes an elongated support structure extending through a central axis of the rolling basket and a plurality of vertical stationary paddles spaced apart along the elongated support structure between the horizontally spaced apart rings.

A sleeve type bushing/bearing is assembled/pressed into a pivoting frame structure. This bearing runs on a spindle tube which is bolted rigidly to a support arm structure. The support arm structure supports the outside diameter of the spindle tube and well as clamping to the end face of the spindle tube. This support eliminates most of the shear load from being applied at the joint face to the bolt outside diameter. The larger outside diameter of the spindle tube can support more shear force through the joint allowing greater functional pressure to be applied through the joint without failure. The Joint can be easily assembled and disassembled in multiple configurations and for replacement of worn parts if needed and includes a sleeve type bearing which is maintenance free and requires no greasing or other lubrication.

An apparatus for breaking up the hardpan subsoil layer of agricultural land has a wheeled frame adapted to connect to a tractor. A roller is rotatably mounted within the frame. A plurality of spike members are attached to the circumferential face of the roller and extend outwardly therefrom beneath the frame for penetrating engagement with the hardpan subsoil layer, to thereby break up the hardpan.

A seed furrow closing wheel includes an annular rim and a plurality of teeth carried on the rim for rotation about an axis. The teeth extend radially outward from the rim and are circumferentially spaced apart from one another.
