An attachment for an industrial or farm vehicle is designed to engage, carry, cut, disturb and/or level dirt at a ground surface, such as a box blade, rake or bucket. Ripper shanks may be adjustably mounted to the attachment, so that a depth of loosening of the ground surface may be controlled. Each ripper shank includes a generally flat metal plate having a rectangular portion, a curved portion, and a triangular portion. A dirt lifting slide is attached to the triangular portion at a position between a top edge and a bottom edge. The top edge may include serrated teeth to cut roots and loosen dirt before the dirt is lifted by the slide. An inside edge of the curved portion may also include teeth to cut roots. An opening or channel is formed near a top edge of the rectangular portion, which functions as a handle to assist in mounting and adjusting the ripper shank relative to its holder.

A subsoil tool for ameliorating soil compaction having a shank attached to a toolbar of a tractor, wings on forward wing links pivotally engaged to the shank, and following wings on a wing rod pivotally engaged with the forward wing link. The forward wing links are positioned near the bottom of the shank in front of the rear of the shank. The wing rod is positioned behind the shank. A power link is engaged to the toolbar, a hydraulic drive cylinder, and the wing rod for enabling oscillation of the wing rod relative to the shank.

There is provided soil loosening and furrower assemblies and a bed renovator therefor. The soil loosening assembly comprises a blade assembly and wherein the blade assembly is horizontally pitched such that, when drawn beneath a soil surface at a fixed depth, the horizontally pitched blade assembly severs rootstock at the level of the blade assembly while retaining the rootstock substantially in place and loosens soil above the level of the blade assembly without substantial soil inversion. The furrower assembly comprises side plates extending rearwardly from a forward prow edge, wherein the side plates are approximately 25-45° with respect to the horizontal axis; and bottom edges of the side plates are approximately 20-40° with respect to a direction-of-travel axis.

An agricultural implement includes a chassis and a shank carried by the chassis. The shank includes: a shank body configured to penetrate a soil top surface; a sensor attached to an outer surface of the shank body and defining a probing area; and a sensor shield carried by the shank body in front of the sensor, the sensor shield being configured to deflect oncoming soil flow away from the sensor without substantially disrupting soil flow into the probing area.

Provided is an earth conditioning system/apparatus which removes/break-ups rock in the ground and has a front drawbar, a ground engaging tool arrangement and a rear rotary device (drum). A ground engaging tool arrangement includes a frame supporting ground engaging tools each mounted at a pivot. Actuators raise/lower the ground engaging tool(s) for desired depth control of the ground engaging tools. The rotary device slotted or ribbed drum acts as a crushing drum rolled over earth that has been broken up by the ground engaging tools. Actuators, provide height adjustment of the ground engaging tools relative to the ground engaging tool support frame and by adjusting the height from the ground of the ground engaging tool arrangement by operating the at least one adjuster acting between the rotary device and the ground engaging tool arrangement.

A tillage point for an agricultural implement includes a body extending in a lengthwise direction between a tip end and a retention end and in a vertical direction between an upper body surface and a lower body surface, where the body defines a retention slot between the upper and lower body surfaces. Additionally, the tillage point has a fin extending outwardly from the upper body surface in the vertical direction. The fin defines a height in the vertical direction between a base end of the fin positioned adjacent to the upper body surface of the body and a top end of the fin positioned opposite the base end. The fin further defines a lateral width between opposed lateral sides of the fin, where the lateral width of the fin tapers along at least a portion of the vertical height of the fin.
