A retainer sleeve includes an at least partially annular body defining an axis of rotation, a radial direction, and a circumferential direction. The body may also have a radially inner annular surface defining a radially inner aperture, and a first anti-rotation feature extending radially inwardly from the radially inner annular surface including a sloping ledge having a locking surface that faces at least partially in the circumferential direction and along a direction that is parallel to the axis of rotation, forming an oblique angle with the direction that is parallel to the axis of rotation.

An agricultural device with a wear resistant coating comprising a shank portion that may be attached to an agricultural implement. First and second rear wings connect to an intermediate portion that connects to the shank portion. First and second shoulders are formed at the points where the rear wings meet the intermediate portion, and a patch of wear resistant coating is applied at each of the first and second shoulders. A first edge tapers forwardly from the first rear wing to a point, and a second edge tapers forwardly from the second rear wing to the point. Wear resistant coating may also be applied to the first and second edges or the point. Wear resistant coating may be applied to the agricultural device in a pattern that is specific to soil type.

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.

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.

A cutting edge for a machine. The cutting edge includes a top side and a bottom side opposite the top side. The cutting edge includes insert apertures along the bottom side. The insert apertures shaped to receive inserts made of harder material than the majority of the cutting edge.

The invention relates to a wear or protection system for a tool of an earth moving machine, comprising a wear element (1), a support (3) and a pin (7) with elastic means (13) housed in a housing (5) having a base surface (27) and a compression surface (29). The base surface (27) and a first portion (31) of the compression surface (29) belong to the wear element (1), and the distance between both has a fixed value Df. A second portion (33) of the compression surface (29) belongs to the support (3), and the distance between the base surface (27) and the second portion (33) is variable depending on the wear of the system, having a minimum value Dmin when the system is new and increasing as wear increases. Dmin is less than Df. The pin (7), in the compressed state, has a height H equal to Dmin, and as the system becomes worn, H increases until reaching the value Df. The pin (7) comprises a recess (23) in its upper surface, and in the first portion (31) there is a projection (25), suitable for being housed in the recess (23).

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 cutting edge for a machine. The cutting edge includes a top side and a bottom side opposite the top side. The cutting edge includes insert apertures along the bottom side. The insert apertures shaped to receive inserts made of harder material than the majority of the cutting edge.
