A snowplow blade assembly is provided wherein the plow blade is provided at its opposite ends with snow deflectors. Preferably the snowplow blade assembly is also provided at its opposite ends with pivotable end extensions to which the snow deflectors are attached. Preferably each end extension is pivotable through an angle greater than about 175.degree. from a fully extended and retained blade end extending configuration to a fully folded and retained blade length reducing and extension storage configuration. Each snow deflector comprises a base, a deflector plate that is pivotable relative to the base, a biasing member, an anchor for fastening the springs to the base, and arm members for connecting the springs with the deflector plate so that the deflector plate is biased into an open but deflectable configuration relative to the base. The snow deflector components are arranged and configured to move snow without becoming snow bound.

[ What is claimed is:] [1.] In a snowplow of the type having an elongated, substantially straight blade having a smooth longitudinally and concavely curved forward face, opposite ends, a backface, and top and bottom edge portions, the improvement which comprises a snow deflector on said forward face

[ What is claimed is:] [1.] In a snowplow of the type having an elongated, substantially straight blade having a smooth longitudinally and concavely curved forward face, opposite ends, a backface, and top and bottom edge portions, the improvement which comprises a snow deflector on said forward face adjacent to one of said opposite ends, said snow deflector comprising in combination:(a) a base plate having a generally flattened medial region with opposed inner and outer opposite side portions and with means for mounting said base plate to said forward face so that a cavity is defined between said base plate and said forward face with said medial region extending generally laterally along and in adjacent relationship to said forward face;(b) a generally flattened deflector plate having opposed inner and outer opposite side portions;(c) hinge means interconnecting said deflector plate inner side portions with said base plate inner side portions for pivotal movement of said deflector plate towards and away from said medial region about a generally upright axis;(d) generally arcuately extending arms having a proximal end portion and a distal end portion at opposite ends thereof, said proximal end portion being connected to said deflector plate and said arms extending backwards therefrom; and(e) biasing means located in said cavity and including an anchoring device connected to said base plate for biasing said deflector plate away from said medial region.
