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.

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.

The present invention relates to a plough device (100) and a method for ploughing a ground (120). A rotatable first plate-like cutting element (102) having a circumferential first cutting edge (103) is arranged on a support structure (101) and is designed such that when the support structure (101) is moved on the ground (120) along a ploughing direction (110), a side region (202) of a soil ridge (201) of the ground (120) can be cut by means of a first cutting region (104) of the first cutting edge (103). A second disc-shaped cutting element (105) having a second cutting edge (106) is arranged on the support structure (101) and is designed such that when the support structure (101) is moved on the ground (120) along a ploughing direction (110), a base region (203) of a soil ridge (201) of the ground (120) can be cut by means of a second cutting region (118) of the second cutting edge (106), wherein the second cutting element (105) is arranged relative to the first cutting element (102) in the ploughing direction (110) such that the second cutting region (118) is arranged before the first cutting region (104) in the ploughing direction.
