Abstract
A V-blade for a snowplow, a snowplow incorporating the V-blade and a method of use thereof. The blade includes left and right wings engaged with a central shaft. A trip edge is provided on each wing and includes a lower section of moldboard, a cutting edge, and snow shield engaged with an upper section of the moldboard via a biasing assembly. The assembly biases the trip edge into alignment with the upper section. When an obstacle on the surface is struck by the trip edge, the trip edge pivots relative to the upper section about a horizontal axis extending along a shaft of the biasing assembly. A translation assembly causes the trip edge to move laterally in a first direction away from the central shaft and parallel to the vertical axis extending therealong. The trip edge returns to its original position under spring force.
