The oldest patent that I could find on a hydraulic snow plow was from 1980. Patent number US4187624 issued on February 12, 1980. It was issued to James R. Blau from Brookfield, Wisconsin. It was filed on March 8, 1978.
The abstract reads as follows:
A snow plow especially suitable for use with small vehicles, such as cars, is disclosed. The snow plow features a hydraulic system for controlling movement of the plow from side to side as well as for elevating the plow. The blade elevating system of the present invention utilizes a bell crank means coupled intermediate the plow frame and a lifting bar located behind the vehicle's front bumper and provides important advantages over conventional lift systems. The snow plow of the present invention also includes a coupling system which permits the plow to be quickly coupled to the vehicle for snow plowing and quick removal of the plow when the vehicle is to be used for its conventional purposes. A system is also provided for locking the plow blade in its elevated position to keep it from falling while the vehicle is being driven from one snow removal location to another. Finally, the invention's hydraulic system is mounted in the vehicle's engine compartment where it can be locked to prevent theft.
This patent covers a number of smaller plows that are made to fit on cars and trucks. It does not deal with hydraulic single use snow plows. You can see a picture of the type of plow covered by this patent in the link I have attached.
