A work vehicle comprising a material management system using moldboard gates. A sensor is configured to generate a signal indicative of a ground feature and a location of the ground feature. A moldboard is coupled to the work vehicle and is configured to move a ground material. A gate is coupled to the moldboard and a gate actuator is coupled to the gate. The gate actuator is configured to move the gate to an open position, a closed position, or to a position in between. A controller which is in communication with the sensor is configured to receive the signal indicative of the ground feature and the location and control the gate actuator to move the gate based on the ground feature and the location.

A convertible snow plow comprises a support frame having a forward end and a rearward end, the rearward end adapted to be mounted to a vehicle, a pair of plow blades hinged together along inboard ends of the blades at a hinge at the forward end of the support frame, an actuator having opposite ends, one end connected to the support frame, and a two-position linkage connected to the other end of the actuator and to at least one of the blades. When the linkage is in the first position the blades are in a straight blade configuration and the actuator is operable to position the blades in straight blade forward, straight blade left, and straight blade right positions, and when the linkage is in the second position the blades are in a V-blade configuration and the actuator is operable to position the blades in forward swept V and rearward swept V positions.

Embodiments of the innovation relate to a plow comprising a plow and a trip blade mechanism coupled to a plow body, the trip blade mechanism comprising a trip blade hingedly coupled to a base of the plow body and a blade return device coupled between the plow body and the trip blade. The plow comprises a back drag system coupled to the trip blade mechanism and configured to dispose the trip blade between a first plowing position relative to the plow body and a second back drag position relative to the plow body.

A grading assembly for simultaneously grading a road and a shoulder is disclosed. The grading assembly can comprise a main moldboard that is elongate along a first longitudinal axis between a first end and a second end. The grading assembly can further comprise a shouldering moldboard that is elongate along a second longitudinal axis between a first end and a second end. A linkage can pivotably couple the shouldering moldboard to the main moldboard at the second end of the main moldboard so that the shouldering moldboard is movable relative to the main moldboard about and between a stowed position and a fully deployed position. An actuator can be configured to pivot the shouldering moldboard relative to the main moldboard by the linkage.

A towed earth moving implement features a longitudinal pull tongue, a winged blade assembly with a transverse center blade and a pair of angled outer wing blades, and a wheeled frame on which the blade assembly is carried. A pivotal blade-pitch between the pull tongue and the blade assembly defines a transverse blade pitch axis about which the blade is adjustable in pitch-angle relative to the pull tongue. In a pitch-neutral position, working edges of the wing blades reside in a same horizontal working plane as a working edge of the center blade, for ground leveling purposes. In an upwardly pitched position, the working edges of the wing blades reside in forwardly inclined relation to the horizontal working plane, for ditching purposes. In a downwardly-pitched position, the working edges of the wing blades reside in forwardly declined relation to the horizontal reference plane, for crowning purposes.

A folding blade for a clearing apparatus with a clearing blade includes a folding bar, a lever mechanism for pivotally mounting the folding bar on a base part of the clearing blade, and a spring element for arrangement between the base part and the lever mechanism, for returning the folding bar to an initial position in which the folding bar forms an extension of a blade plate of the clearing blade. The lever mechanism is designed in such a way that the folding bar is pivotable from the initial position to a retracted position along a first pivoting path by overcoming a spring force of the spring element, and that the folding bar is pivotable from the retracted position to the initial position along a second pivoting path due to the spring force.

The present invention is a device to remove gravel from a roof. The device is a blade assembly vertically mounted on a riding drive mechanism, such as a tractor, and the blade assembly has a smooth, horizontal blade, such as used for snow plowing, and mounted proximate and parallel to the smooth blade is a serrated blade having an up position and a down position. In the down position, the serrations extend to the roof to loosen and remove gravel. In the up position, the serrations are above the edge of the smooth blade which scrapes the loosened gravel. A downward force is provided to force the serrations between the gravel.

The device includes two opposing lateral wings forming the right and left sides of the scraping device. Each wing includes an upper section through which the wing is attached to the central support about a vertical pivot axis, and a bottom section that is pivotable with respect to the upper section about a first horizontal pivot axis. Each wing can follow the unevenness of the roadway surface and may also include parts that can pivot backwards in case of a frontal impact with an obstacle. The scraping device offers a very high degree of versatility and can clean various kinds of roadway surfaces with an unprecedented level of efficiency.

A blade for a work machine includes a body having a main portion including a top edge, a bottom edge, a first lateral edge and a second lateral edge. A wing portion is pivotally coupled to the body about a pivot axis. The first lateral edge includes a curved edge extending outwardly towards the wing portion, where the curved edge forms an apex between the top edge and the bottom edge. A first axis is defined through a first intersection point and a second intersection point, the first intersection point located at an intersection of the top edge and the first lateral edge and the second intersection point located at an intersection of the bottom edge and the first lateral edge. A second axis is defined through the apex and is parallel to the first axis. The pivot axis is located between the first axis and the second axis.

A system and method for automatically adjusting the pitch of a work implement attached to a work vehicle, wherein the work implement has adjustable wings. The system and method include moving materials with a blade having an adjustable wing located at one end of a center portion of the blade, wherein the blade is operatively connected to the work vehicle and is positionable with respect to the work vehicle in response to an operator command. A commanded position of the blade is identified based on a blade positioning signal received from the operator command transmitted by an operator control device. An inclined position of the adjustable wing with respect to the center portion of the blade is identified. A pitch of the blade with respect to the work vehicle based is automatically adjusted based on the identified commanded position of the blade and the identified inclined position of the adjustable wing.
