SNOW-PLOW SYSTEM FOR ATTACHMENT TO A VEHICLE, COMPRISING A REACTIVE CONSTANT PRESSURE SNOW PLOW MECHANISM, A QUICK CONNECTING/DISCONNECTING SNOW PLOW APPARATUS, AND A LIGHTING SYSTEM

摘要

A snow-plow system having four major features: lighting system, a quick and easy disconnect/connect system, a reactive controlled pressure mechanism for applying a controlled pressure to the bottom edge of the moldboard of the plow, and a simple electric control to activate or deactivate the reactive controlled pressure mechanism. The present invention may be summarized as a snow-plow system that is mounted to a vehicle having a mounting frame by an easy connect and disconnect system connecting to the A-frame of the snow-plow by use of three mounting pins which hold the snow-plow system in place on the mounting frame of the vehicle and thereby rigidly connect the system to the vehicle. A light bar or lighting system also is rigidly mounted to the A-frame of the snow-plow at the mounting pins so that once the position of the lighting system is determined the relative position of the lighting system with respect to the vehicle does not change. A reactive controlled pressure mechanism that consists of a hydraulic control unit is operated by an electric control unit mounted in the vehicle. A reactive controlled pressure cylinder is pivotally mounted to the bottom of the A-frame and mechanically connected to the moldboard of the plow.
