ABSTRACT:
A wing plow yoke which may be manually actuated to laterally move outwardly from the front side of a plowing vehicle to allow access to the vehicle's hood, and thus to its engine. Mounting brackets attached to opposite sides of the front of the vehicle are provided with bracket apertures wherein a yoke bar is fit so that the yoke bar can move within the bracket apertures. A gear wheel or a fulcrum-and-lever arrangement is provided which engages a series of spaced depressions situated along the length of the yoke bar. By turning the gear wheel, or by selectively engaging depressions in the yoke bar with the lever, the yoke bar (and thus the wing plow) is moved laterally outwardly from the side of the vehicle. This arrangement avoids the need for any power transmission from the engine in order to move the yoke bar, and thus the yoke bar (and wing plow) may be moved outwardly from the side of the vehicle even in the event of engine failure. Advantageously, exposure to road debris, ice, and other elements increases the friction between the yoke bar and the mounting brackets so that the yoke bar is resistant to unwanted motion within the mounting brackets.
