ABSTRACT:
Guards, usually used in pairs as replaceable attachments to snow plow blade, are shown. At least one of the pair consists essentially of a panel portion with an integral curb feeler extending therefrom and supported thereby that sweeps around a blade end and reaches rearwardly; the curb feeler extension on its mate is optional. The guards comprise deformable polymer. Advantageously the polymer is laminated with a lamina of a hard metal such as steel that is fitted with an especially abrasion-resistant bottom edge. An assembly of the laminae typically is held together with bolts to the plow, and the laminae can be adhesively bonded together also, if desired.
