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 one another. A trip edge is provided on each wing and includes a lower section of moldboard, a cutting edge, and a snow shield. Each trip edge engages an upper section of the associated moldboard via a biasing assembly. The biasing assembly biases the trip edge into alignment with the moldboard's upper section and also biases the trip edge towards a central vertical axis. When the V-blade strikes an obstacle on the surface during snow removal, the trip edges individually pivot about a horizontal axis extending along a shaft of the associated biasing assembly. The trip edges subsequently translate linearly along the horizontal axis and away from the vertical axis.
