ABSTRACT:
A bristle support, having semirigid long lasting bristles, is attached to a snow plow near the lower cutting edge of the plow blade so that the semirigid bristles project below the blade edge and serve the multiple functions of: rigidly contacting the surface to be cleared thereby providing a cutting action on the undesired material on the surface to be cleared and a brushing of the surface; and at the same time having the flexibility to yield to and ride over small surface irregularities and resiliently return to normal position when the irregularities are passed.
