A ground-working tool including a shank and a sub-soil point at the bottom end of the shank. The sub-soil point has a leading cutting edge transverse to and in front of the longitudinal axis of the shank, a back portion behind the shank, a top portion from the leading edge to the shank, a bottom portion, and opposite lateral sides. A soil-rolling surface on at least one of the opposite lateral sides of the sub-soil point, each soil-rolling surface being concave in cross-section between top and bottom edges along a front to back length.

A side plate configured for a tillage shank having a point on a forward edge of the tillage shank and a point base on a bottom edge of the tillage shank to dampen abrasive forces from soil flow includes a modified side plate extension portion having a modified side plate extension portion front edge, the modified side plate extension portion being configured such that the modified side plate extension portion front edge abuts a rear edge of the point on the forward edge of the tillage shank from the point base on the bottom edge of the tillage shank to above a soil line; an attachment portion having an attachment portion front edge, the attachment portion being configured such that the attachment portion front edge does not abut the rear edge of the point on the forward edge of the tillage shank above the soil line; a projection configured to engage the point base; a slot configured to engage the point base; and an opening configured to receive a transverse bolt.

A retention assembly, to slidably retain a blade to a support bracket of a grader machine, includes a yoke, a bearing arrangement, and one or more pins. The yoke is adapted to be coupled to the support bracket, and includes a first sidewall, a second sidewall, and a cavity defined therebetween. The first sidewall defines a first thickness and one or more first bores. The second sidewall defines a second thickness and one or more second bores. The second bores are correspondingly co-axial to the first bores. The bearing arrangement is received within the cavity and is adapted to support the blade for a sliding movement of the blade relative to the bearing arrangement. Further, the pins extend correspondingly through at least one of the first bores or the second bores, and into the cavity to engage and retain the bearing arrangement within the cavity.

The present invention relates to formations to plow the surface layer of a land using modular agricultural implement of drag and respective components (1). It was developed to attend specific agricultural activities in areas of compatible dimensions and to carry out the overturning of the superficial layer of the soil, leveling, and/or incorporating correctives and fertilizers, as well as reducing compaction to increase porous spaces and increase the permeability and storage of air and water. It is assembled in modules under different forms of assembly, highlighting there are the triangular agricultural formation in three versions, triangle forward, triangle backward, and agricultural formation large triangle, and the agricultural formation in rhombus in two versions, the simple rhombus, and the large rhombus.

A consumable shin for a tillage shank includes an integral U-shaped shin having a first side, a second side, and a bottom; the first side and the second side being spaced apart to form a volume therebetween; the first side having a first side surface having first side length and a first side width; the second side having a second side surface having a second side length and a second side width; the first side length being from a rear edge of a guard of a shoe engaging the tillage shank to a forward edge of a first side shield engaging the tillage shank; the second side length being from the rear edge of the guard of the shoe engaging the tillage shank to a forward edge of a second side shield engaging the tillage shank.

A shank assembly for an agricultural tillage implement including a support arm, a shank connected to the support arm, a point connected to the shank, and a float monitoring system. The float monitoring system includes a first sensor for sensing a home position, a second sensor connected to the support arm and configured for sensing an angular position of the support arm relative to the frame of the agricultural tillage implement, and an electronic control unit operably connected to the first sensor and the second sensor. The electronic control unit is configured for comparing the home position and the angular position of the support arm and determining a float of the shank as the shank is towed in a forward direction of travel.

The invention relates to a cutting element (1) made of cemented carbide for an agricultural soil cultivation tool for cutting into the earth, comprising a top side (2) and a bottom side as well as a front side (3), a back side (4) opposite of the front side (3), and at least one lateral surface (5), wherein the top side (2) and bottom side are connected via the front side (3), back side (4), and the at least one lateral surface (5) and the front side (3) comprises a cutting region having multiple teeth, wherein at least one tooth is formed with a first flank (6) and a second flank (7). To achieve an efficient cutting into the earth with a complete cut through the weeds or herbaceous plants present in the earth, it is provided according to the invention that a profile line of the first flank (6) and a profile line of the second flank (7) have different lengths. In this manner, the weeds can be completely severed and thus killed, whereby a use of sprays for killing weeds is reduced and the environment can be protected to a considerable degree.
