ABSTRACT:
A hinged snowplow includes a T-shaped support frame for attachment to a vehicle, the support frame having a free end. A cowling having a pair of extending plow blades pivotally secured thereto, is pivotally secured to the free end so as to pivot in a generally vertical plane about the free end. The cowling has a first stop engageable with the support frame to limit pivotal movement of the cowling about the frame to a first or normal plowing position. A second stop on the cowling is engageable with the support frame to limit the pivotal movement of the cowling about the frame to a second or tipped position. A trip bias mechanism between the frame and the cowling biases the cowling and plow blades to the first position in which the blades are normally positioned for plowing. The cowling and blades are rotated against the trip bias mechanism toward the second, tipped position when the blades hit an obstacle.
