Abstract
In earthmoving equipment, such as a scraper, an adjustable feedthrough protective bit is mounted on each side wall of the bowl in position to protect the leading edges of the bowl in the vicinity of a cutter blade extending between said side walls. Guide straps or abutments are provided on the walls to hold each bit in fixed position on the bowl and a novel arrangement of apertures and openings are provided in each bit and in the wall of the bowl to facilitate effectively securing the bit to the bowl. The bit configurations may be such as to permit end-for-end reversal of orientation of the bit and to provide for use of the bit on either side of the equipment.
