A shank assembly for an agricultural tillage implement including a shank, a point removably connected to the shank, and a protective guard removably connected in between the point and the shank. The point retains the protective guard on the shank. The protective guard is configured for protecting the shank and flexing in response to a movement of the shank.

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.

A share for a soil cultivation implement for cultivating soil. The share is bent and has at least one mounting hole for receiving a fastener, and the share is tipped on an upper side with at least one carbide insert. A bend of the share has a plurality of different bending radii.

In the case of a soil cultivation device with multiple harrow tines, the harrow tines are fastened to levers, which are mounted to pivot on tie bars of the supporting frame via carriers. The operating position of the harrow tines is defined by the levers being adjacent to tie bars, and the harrow tines are prestressed into the operating position by springs assigned to them in the form of pneumatic cylinders.

A wearing part arrangement (1) provided with a holder (11) providing releasable attachment of a wearing part (12) by means of a socket-and-pin type quick-fit coupling, wherein the holder (11) comprises a pair of opposing first guide portions (1132) being arranged to face corresponding supporting faces (1221) provided on the wearing part (12), and a pair of second guide portions (1134) arranged to face corresponding top faces (1223) of the wearing part (12), wherein one of the pair of the opposing first guide portions (1132) and the corresponding side supporting faces (1221) of the wearing part (12) is provided with at least one elevation (1222), and the other one of the pair of the opposing first guide portions (1132) and the corresponding side supporting faces (1221) is provided with a corresponding recess (1135) arranged for receipt of the elevation (1222) when the wearing part (12) is in engagement with the holder (11).

A harrow has a frame, tines pivotal on the frame and each a lower arm with a soil surface under the harrow. An actuator on the frame can shift a bar frame shiftable horizontally on the frame. Respective spring biasing units above the axes each have a guide element connected to the bar frame and displaceable therewith through a predetermined displacement path, a connecting element connected to respective upper arms of the tines, a first compression spring bearing on both of the elements and biasing the other element away from the one element so as to press the lower arm downward into the soil surface during movement of the respective guide element through the path, and a second compression spring bearing continuously on one of the elements and engageable with the other of the elements after displacement of the respective spring-biasing unit only through a part of the path.

A system for monitoring wear of shank attachment members of an agricultural implement includes a shank extending between a proximal end and a distal end, the proximal end configured to be pivotally coupled to a portion of the agricultural implement, a shank attachment member coupled to the distal end of the shank, a non-contact sensor positioned remote to the shank attachment member, the non-contact sensor configured to detect a parameter indicative of wear of the shank attachment member, and a controller communicatively coupled to the non-contact sensor. The controller is configured to determine a status of the wear of the shank attachment member based on sensor data received from the non-contact sensor while the shank attachment member is above ground.
