Abstract
The present invention includes a snow plow assembly adapted to be carried by a vehicle and including a snow plow mounting frame adapted to be fixedly secured to the vehicle frame, a plow blade, means for supporting the plow blade for vertical movement and a plow blade supporting member pivotally attached to the mounting frame for pivotal movement about a horizontal axis and for carrying a plow blade. Means are also provided for selectively causing vertical movement of the plow blade and including a linearly extensible member having a screw connected to the snow plow mounting frame, a threaded member threadably housing an opposite end of the screw, and an electric motor drivingly connected to the threaded member for selectively and alternatively driving the threaded member to cause relative rotation of said threaded member whereby the plow blade is moved vertically.
