ABSTRACT:
A plow assembly useful for moving material from surfaces such as roadways in various selectable discharge directions includes a moldboard assembly and pivotable frame. The moldboard assembly is capable of being oriented in a right side discharge or a left side discharge in response to pivoting movement of the pivotable frame. A tripping mechanism is included to prevent damage of the plow assembly from obstacles located on the plowing surface. A cutting edge of the plow assembly is secured to the moldboard assembly by a wedge mechanism thus allowing quick cutting edge replacement.
