Abstract
An arrangement for modifying a plow blade power unit of the type positioned between the mounting frame on the front of a vehicle and a plow blade lift arm, to a unit for creating pressurized fluid from a remote location. Modification enables a basically similar power unit to be utilized in both remote and direct operational environments with only minor substitution of interchangable parts. A piston-cylinder unit which enables direct lifting of a plow blade is replaced by a modified, but similar, cylindrical element for use in indirect lifting of a plow blade by fluid under pressure.
