  • Back plow blade construction
    Patent number: 5715613
    Abstract: The present invention relates to a blade which can be removably secured to the bottom of a conventional snow plow. The blade enables the operator of the snow plow to collect snow in either the forward or rearward running directions of the snow plow. This blade has a construction which specifically enables the blade to be employed beneath a conventional snow plow. More specifically, the blade of the present invention includes an angularly positioned forward plow surface and a rearward plow surface. These two plow surfaces are interrelated by way of a number of equally spaced reinforcing ribs. Securement means are included to enable the forward plow surface to be removably secured to the bottom edge of a conventional snow plow.
