A knife for creating berms in agricultural fields for strip-till farming is improved by adding wings on opposing sides of the knife edge that are configured to fracture and raise soil in a wider path for building a berm behind the knife. The wings can be swept back, angled downward from front to back, and angled downward from inside to outside, for better loosening compacted soil below the surface and creating improved berms rearward of the knife. The knife edge can be replaceable by removal of a single pin. If a difficult object is encountered, such as large rocks or tree roots, the knife can swing reward with respect to a supporting shank to minimize damage to the knife. Upon swinging reward, an agricultural product delivery tube rearward of the knife for depositing agricultural product into the berm can swing forward to minimize crimping of the delivery tube.

A wearing-part arrangement for a leading edge of a soil-working implement includes a point configured to be releasably attached to the soil-working implement. The point has a pointed front portion and a transverse elevation projecting from an upper face thereof. At least the front portion is mirror-symmetrical around a longitudinal axis of the point and has first and second oblique faces diverging in a direction of a socket on the point and merging with a first side edge surface and a second side edge surface. The first oblique face is bounded by a first cutting edge, and the second oblique face is bounded by a second cutting edge. When the point is attached to the soil-working implement, at least a rear portion of the second oblique face and the second side edge surface adjacent to the second oblique face project beyond a side edge of the soil-working implement.

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 drive box having a hydraulic cylinder is engaged to the toolbar and pivotally engaged with the wing rod. In use, a portion of the subsoil tool may be inserted below a surface of the soil, the height of the subsoil tool may be adjusted, the subsoil tool may be rotated, and the hydraulic cylinder may be cycled to move the forward wings and following wings.

A chisel sowing coulter, for direct and/or mulch sowing, includes: a coulter body, a tear-open chisel fastened by a fastening device, and coulter blades laterally projecting from the tear-open chisel and provided with a front cutting edge, which are arranged in order to create a sowing furrow in the ground. In order to change the penetration depth of the sowing coulter into the ground, the coulter blades are adjustable about a horizontal axis that extends transversely to the direction of travel, and that is fixable in different positions by way of an adjustment device arranged between the tear-open chisel and the coulter body.

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.

A turning plowing device 1 with blade-like cutting elements 3 situated on both sides of a plow beam 2 is provided, in which at least one first cutting element 4 on one side, having a hollow disc-like design, is provided. This first cutting element 4 is swivelably arranged, and may be swiveled from a first position on a first side of the plow beam 2 into a second position. In the first position, the second cutting element 3 is associated with a respective first cutting element 4 in such a way that a complete module made up of these two cutting elements is formed. A row of second cutting elements 3 formed at the plow beam 2 represents semi-modules, which likewise form a complete module only after the respective first cutting elements 4 swivel into the corresponding working position. Plowing takes place only using a formed complete module. For this purpose, after the plowing of a furrow in the first direction, the plow and the first cutting element 4 having a hollow disc-like design are turned in such a way that during back-plowing in a plowing direction 5 opposite the previous direction, plowing may be carried out with identical angles. For this purpose, after the swivel arm 6 together with the first cutting element 4 is swiveled with respect to the cutting element 3 and the turning plowing device is turned by 180?, the plow rotates in a manner of speaking, so that an identical plow pattern may be created in the opposite direction.
