A plow assembly for vehicles such as pickup trucks and tractors for moving snow or other materials, as well as for bulldozers, graders and the like for excavating and grading dirt, sand, gravel or other plowable materials, has at least one extendable, forwardly pivotable plow wing which is extendable on one end of a main plow by sliding movement along the rear 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. At least one actuator, such as an hydraulic fluid power cylinder, is connected to the plow wing to move the wing between the retracted, extended and forwardly angled positions. In a preferred embodiment, an extendable plow wing is included on each end of the main plow with at least one actuator connected to each of the respective plow wings. Optionally, each plow wing may be movable via a pair of actuators, whereby the actuators 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, dirt, sand or other plowable material without the material slipping off the plow blade ends. The main plow may include a section formed from polymeric sheet material for weight reduction. Because the plow wings are movable along the rear surface of the plow, the front surface of the plow provides a substantially continuous, uninterrupted surface for moving the plowed material therealong.

Plow with rear mounted, adjustable wing

A plow assembly for vehicles, such as pickup trucks and tractors, or bulldozers or graders, for moving snow or other plowable materials has at least one extendable, forwardly pivotable plow wing which is pivotable at a hinge at one end of a main plow for movement between an aligned position and a forwardly angled position in which the plow wing front surface extends at an angle to the plow front surface. The plow wing includes an inner and outer portion, whereby the outer portion is slidably mounted to the inner portion for sliding movement along the inner portion between a retracted and an extended position. One or more actuators, such as fluid power cylinders or the like, are connected to the plow wing to move the wing between the retracted, extended, aligned and forwardly angled positions. In one preferred embodiment, an extendable plow wing is pivotally mounted 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, aligned 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 material slipping off the plow blade ends. The wings are extendable and retractable when the plow is in the U-shape in order to adjust the carrying capacity of the plow.

Adjustable wing plow with fixed pivot

A plow assembly for vehicles such as pickup trucks and tractors for moving snow or other materials, as well as for bulldozers, graders and the like for excavating and grading dirt, sand, gravel or other plowable materials, 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. The plow wing is also pivotally mounted on a hinge for movement between an aligned position and a forwardly angled position in which the plow wing front surface extends at an angle to the plow front surface. At least one fluid power cylinder is connected to the plow wing to move the wing between the retracted, extended, aligned, 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 are operable independently of one another to move the plow wings independently between their respective retracted, extended, aligned 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, dirt, sand or other plowable material without the material slipping off the plow blade ends. The plow wings may be pivoted to their forwardly angled positions irrespective of the degree of extension of the wings from the main plow blade. Similarly, the plow wings may be extended or retracted irrespective of the degree of forward angling of the plow wing with respect to the main plow blade.
