The circle assembly includes plate and rim member coupled to plate. The plate defines front section and rear section and includes a ring gear portion defining a plurality of teeth formed integrally therein. A first skirt portion and a second skirt portion integrally and contiguously extend from ring gear portion at rear section. The first skirt portion and second skirt portion are angled relative to ring gear portion in direction of rotation axis. The rim member includes first arm member and second arm member attached to first skirt portion and second skirt portion, respectively, and a circumferential belt portion extending between the first arm member and the second arm member. The belt portion is spaced from and surrounds ring gear member at the front section of the plate.

An excavator for earthmoving and construction includes a main frame, a rotatable cabin mounted on top of the main frame, a boom, a stick, a digging bucket, and a slidable plate assembly attached to the main frame that is capable of distributing the weight of the rotatable operator's cabin. The excavator optionally includes a removable dump bed mounted to the main frame for receiving material from the digging bucket.

A ground engaging tool control system including a first sensor system, a second sensor system, a first actuator system, a second actuator system, and an electronic data processor. The first and second sensor systems detect respective positions of a first ground engaging tool and a second ground engaging tool. The first actuator system is coupled to the first ground engaging tool and the second actuator system is coupled to the second ground engaging tool. The electronic data processor determines a target grade profile and generates two or more control signals to adjust target positions of the first ground engaging tool and the second ground engaging tool. The target position of the second ground engaging tool is determined based on at least one of a position of the first ground engaging tool or the comparison of a current grade profile and a desired grade profile.

Ground/face working apparatus (1) comprises a primary support portion (2) for mounting to a vehicle and an accessory body portion (3) including or allowing the attachment of an accessory such as a blade (5). Multiple fixed length links (4a-c) allow and limit a degree of relative movement between the accessory body portion (3) and primary support portion (2) including lateral, vertical, and roll rotational (about a horizontal longitudinal axis). Control actuators (6a, 6b) primarily control the aforesaid rotational and vertical dispositions of the portions (2, 3) while a side shift variable length link comprising an actuator (8) affects the amount of lateral movement.

A grading machine may include a machine body, a grading blade, at least one grading blade sensor configured to sense a position and orientation of the grading blade, a drawbar connecting the grading blade to the machine body, at least one drawbar sensor configured to sense a position and orientation of the drawbar, a user interface, and a control system. The control system may be configured to receive an input from the user interface and position and orient the grading blade and the drawbar to one of a plurality of predetermined ditching positions based on the input.

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.

A bifurcated feed material pusher blade has a main blade with a selectively positionable wing member secured to the distal end of the main blade. The bifurcated pusher blade can be formed with two main blades connected at a forward end to a centerpiece and oriented at opposing angles relative to the direction of travel during operation. The two wing members can be independently adjustable relative to the main blades by manipulation of hydraulic cylinders. The two main blade members can be pivotally connected to the centerpiece to permit angular adjustment of the two main blades relative to the direction of travel. The frame supports extending between the two opposing main blades can be telescopic, either manually or powered by hydraulic cylinders for angular adjustment on the go, to facilitate the angular adjustment of the main blades.

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.
