A wear-resistant alloy is inlaid in channels along the undersurface of a cutting edge of a ground-engaging implement. The channels include a front channel adjacent to the front cutting edge, and channels extending rearwardly from the front channel along the sides of the implement. The wear-resistant material is cast in the form of blocks and brazed in the channels. Additional wear-resistant material may be provided at the corners where the front channel intersects the channels along the sides.

Cutting edge with wear-resistant material

A bucket with a bottom wrapper sheet and adjacent side plates has strips of material welded thereto at critical wear areas. The strips have a plurality of inserts of a hard wear-resistant material bonded into openings in said strips, which strips and inserts are heat treated prior to welding to the bucket. When excessive wear of the strips and inserts has taken place, the strips are removed and new strips with new inserts are welded to the wear areas of the bucket. A method of making and applying wear strips to a bucket is disclosed which includes the steps of forming and shaping the strips, drilling cavities into the shaped strips, bonding preformed inserts in said openings, heat treating the strips with the inserts bonded therein, and attaching the strips to said bucket.

Wear strips for earthmoving buckets

A wear-resistant alloy is inlaid in a channel along the undersurface of a cutting edge of a ground-engaging implement. The wear-resistant alloy is in the form of individual blocks which are brazed within the channel. The joints between contiguous blocks are non-parallel to the general direction of travel of the ground-engaging implement for improved tool wear.

Ground-engaging tool inserts with angled edges

A composite ground engaging tool is disclosed including a first plate having leading and trailing end portions, first and second surfaces, and a cutting edge on the leading end portion, a second plate having leading and trailing end portions, first and second surfaces, and a cutting edge on the leading end portion, the plates being substantially coextensive and of a construction sufficient for spacing the leading end portions from each other during contacting of the first surfaces and being connected together to define a deep slot between them, and a wear-resistant member disposed within the slot and secured to the plates.
