CA 2229783

A plow assembly is disclosed for vehicles such as pickup trucks and tractors for moving snow or other materials. The plow assembly has at least one extendable, forwardly pivotable plow wing which is extendable on one end of a main plow by sliding movement along the front of the plow between a retracted and an extended position in which the plow wing is generally aligned with the plow front surface. The plow wing is also pivotally mounted on a hinge for movement between the extended position and a forwardly angled position in which the plow wing front surface extends at an angle to the plow front surface. A pair of fluid power cylinders are connected to the plow wing to move the wing between the retracted, extended and forwardly angled positions. In the preferred embodiment, an extendable plow wing is included on each end of the main plow with a pair of fluid cylinders connected to each of the respective plow wings. The fluid cylinders in each respective pair are operable independently of one another to move the plow wings independently between their respective retracted, extended and forwardly angled positions. When both plow wings are pivoted to their forwardly angled positions, the plow assembly has a general U-shape which facilitates pushing snow or other material without the snow slipping off the plow blade ends. The main plow may include a section formed from polymeric sheet material for weight reduction.
