ABSTRACT:
A plow for mounting to a vehicle is disclosed. The plow can include a moldboard having a movable cutting edge and an adjustable bias trip mechanism having a biasing member preferably in the form of a spring. The adjustable trip mechanism can be arranged with the cutting edge of the moldboard to urge the cutting edge to a plowing position. The spring can be cooperatively arranged with a retainer, a pin for example, at one or more retaining positions to impart a preload biasing force upon the spring that varies according to the retaining position selected. The preload biasing force can act as a trip resistance force which must be overcome before the cutting edge moves. A lever tool can be provided for adjusting the spring.
