ABSTRACT:
A high-performance plow system to be attached to a pickup truck or similar vehicle. The plow blade can be angled across the plowing surface and with respect to the motion of the vehicle up to about 45.degree., it can roll to allow the blade to track changing pitch angles along the plowing surface contours. The blade has two protective mechanisms, the first one being an appropriately-designed rake angle scraper structure, disposed at the bottom edge of the plow blade, the second one being a mechanism which attaches the blade to an A-frame assembly (AFA) by pitch and shear pins. The shear pins break if too tall an object is hit and allow the blade to fall over the object. The pins allow 30 second removal/attachment of blade. The AFA is described as being L-shaped when viewed from a side view, which shape causes it to produce forces (that are necessary) to keep the blade's scraper structure on the plowing surface, and allows it to be raised to a substantially vertical position when the plow is in its inoperative mode. This reduces truck front-end wear, and increases maneuverability of the vehicle when not plowing.
