Abstract
A snowplow assembly includes a mount assembly operatively connected to an associated vehicle, a plow blade assembly pivotally connected to the mount assembly, and a cylinder with a first end pivotally connected to the mount assembly and a second end pivotally connected to the plow blade assembly. The cylinder can include at least one resilient member. The resilient member exerts a force in a first direction when the plow blade assembly is in a first angled position, and the resilient member exerts a force in a second direction when the plow blade assembly is in a second angled position.
