A cutting edge component for a work tool on an earth-moving machine may include a longitudinally-extending wear component and a support surface connectable to a moldboard of the earth-moving machine. The wear component may include at least one wear portion connected to the support surface, and the at least one wear portion may form at least one ground engaging edge. The at least one wear portion may include a mild steel body and a plurality of longitudinally-spaced white cast iron teeth vacuum brazed along a distal, ground engaging edge of the mild steel body. The plurality of teeth may each be shaped with two intersecting substantially planar surfaces arranged to mate with at least a surface extending between the distal, ground engaging edge and at least one of a rearward-facing surface of the mild steel body and a front-facing surface of the mild steel body on at least one of a side of the mild steel body facing away from a direction of travel of the machine and a side of the mild steel body facing in the direction of travel of the machine to form a brazed joint. Each tooth may include a material directing feature defined in a front-facing surface of each tooth when the tooth is brazed to the mild steel body.

An appliance can be used to mitigate or even eliminate wear from soil abrasion on the tine or shank of a cultivator. The appliances is made of a polymer and is positioned between the tine or shank and a sweep. The appliance is conveniently replaced whenever a worn sweep is replaced. By protecting the tine or shank from wear, the comparatively much more expensive tine or shank can be replaced at much longer intervals. This can save both equipment costs and downtime.

A residue coulter apparatus is configured to cleanly sever and clear crop debris from a planting row, causing minimal disturbance to the soil. The residue coulter apparatus comprises a pair of crop debris clearing discs each having a plurality of back-swept teeth extending about their periphery. The teeth are separated by recesses formed between the teeth. The clearing discs are located on opposite sides of the planter and are angled toward each other so that the leading edges of the clearing discs are pointed in a toe-in orientation. The residue coulter apparatus also includes floater wheels that are coupled to a first side of the crop debris clearing discs. The floater wheels include a series of tines that are configured to be aligned with the teeth of the clearing disc such that there is one tine per tooth of the clearing discs. The floater wheels also include a series of recesses formed between the tines wherein the recesses are aligned with the recesses formed in the clearing discs.
