Abstract
A multi-position snowplow blade, a snowplow incorporating the blade and a method of use thereof. The blade includes left and right wings that each having a trip edge pivotally engaged therewith. Each trip edge includes a lower section of a moldboard, a cutting edge, and a snow shield. A biasing assembly biases the trip edge into alignment with an upper section of the moldboard. The trip edges trip when the blade strikes an obstacle on a surface being plowed. When the trip edge trips, it pivots about a horizontal axis and relative to the associated upper section. Each snow shield pivotally engages the lower section of the associated trip edge and pivots relative thereto when the trip edge trips. The pivotal motion of the two snow shields widens a gap therebetween and helps to reduce the possibility of damage to the pivoting trip edges.
