ABSTRACT:
A skid shoe for a snow plow blade is attached to the plow moldboard at the pre-existing bolt holes used to fasten the blade to the moldboard such that the shoe is mounted close to the cutting edge of the blade. Hard carbide wear bars or strips are fastened to the skid shoe for reducing the abrasive action on the cutting edge of the blade thereby prolonging the life of the blade. Each wear bar consists of a steel envelope packed with a carbide-bronze matrix. The wear bars are weldable to the skid shoe and easily replaced by welding a new bar on the top of an old one or by welding a new bar directly to the skid shoe. The steel envelope works to hold the carbide-bronze matrix together, and the ductile bronze gives the hard carbide additional durability and shock absorption, which means longer shoe life with less blade wear.
