In some implementations a lift assembly for a snow wing assembly may include a first lifting mechanism, coupled to the motor grader, configured to lift the snow wing assembly a first portion of a bench height associated with a moldboard via a first hydraulic cylinder. The lift assembly may include a second lifting mechanism, coupled to the first lifting mechanism and the moldboard, configured to lift the moldboard of the snow wing assembly a second portion of the bench height via a second hydraulic cylinder. The lift assembly may include one or more valves included in a hydraulic circuit of the first hydraulic cylinder and the second hydraulic cylinder, configured to divert a flow of hydraulic fluid in the hydraulic circuit away from a first stage hydraulic cylinder and to a second stage hydraulic cylinder, based on a pressure value associated with the first stage hydraulic cylinder.

A system for extracting a motor grader from a location with reduced traction includes the motor grader having articulated front and rear frames supported on front and rear wheels, respectively, and a blade extending from the frame toward the surface underlying the grader. A plurality of blade articulation structures are adapted to articulate the blade relative to the frame. A plurality of sensors are provided and a steering mechanism, power source and control system having a controller. The controller is configured to receive the plurality of signals and perform an extraction procedure to reposition the motor grader. The extraction procedure includes automatic execution of a sequence of operations including a plurality of modification of an articulation angle of the front and rear frames, a steering angle, a position of the blade, a disposition of the blade, propulsion of one or more of the wheels, and direction of propulsion.

An assembly for a motor grader is disclosed. The assembly includes a blade operatively attached to a frame of the motor grader and configured to engage a ground surface. The blade includes a first segment and a second segment. The assembly further includes a movement actuator for moving the blade with respect to the frame in a first direction. The movement actuator includes a rod member having a first portion and a second portion. The first portion is secured to the first segment of the blade and the second portion is secured to the second segment of the blade.

A motor grader includes an engine, a power transmission apparatus, a selective catalytic reduction apparatus, a fuel tank and a reducing agent tank. The power transmission apparatus is configured to transmit power from the engine. The selective catalytic reduction apparatus is configured to process exhaust from the engine. The fuel tank is configured to retain fuel. The reducing agent tank is configured to retain a reducing agent. The fuel tank is arranged so as to at least partially overlap with the engine in a planar view. The fuel tank is arranged between the power transmission apparatus and the reducing agent tank in a vehicle front to back direction.

A motor grader in which a motive power source of an electric motor can appropriately be arranged is provided. The motor grader includes a front frame, a rear frame, and a coupling shaft. The rear frame is arranged in the rear of the front frame. The coupling shaft couples the front frame to the rear frame as being pivotable with respect to the rear frame. The motor grader includes a front wheel rotationally driven to run the motor grader, the electric motor that generates driving force for rotationally driving the front wheel, and a battery in which electric power supplied to the electric motor is stored. The battery is arranged in front of the coupling shaft.

Motor graders and circle drives associated with the same. An example work vehicle includes a frame, a circle drive coupled to the frame, moldboard coupled to the circle drive and a planetary gear apparatus including an output shaft configured to mesh with the circle drive to rotate the circle drive relative to the frame.

A work attachment for a work machine is disclosed. The work attachment has a moldboard that has moldboard apertures and moldboard fasteners along its bottom surface. The work attachment also has a clamp bar having its own set of apertures to receive the moldboard fasteners for attaching the clamp bar to the moldboard. The clamp bar slides around the moldboard fasteners, along a longitudinal axis of the moldboard, from an open position to a closed position to attach a cutting edge to the moldboard.

A system for retaining a moldboard to an implement frame of a grader machine includes one or more brackets, one or more actuators, and one or more bump stops. The brackets are coupled to a backside of the moldboard and are coupled to the implement frame about an axis. The actuators are coupled to respective brackets and are configured to tilt the brackets with respect to the implement frame about the axis to articulate the moldboard with respect to the implement frame. The bump stops are coupled to the implement frame and are configured to contact the respective brackets when the moldboard articulates from an intermediate position to one or more deviated positions.

A system includes one or more brackets pivotably couplable to the implement frame. The bracket defines a first bearing arrangement and a second bearing arrangement to accommodate a sliding movement of the moldboard with respect to the implement frame. The first bearing arrangement is located relatively distal to a working edge of the moldboard than the second bearing arrangement. The first bearing arrangement includes a mounting block, a piston disposed and movable within at least one through-bore of the mounting block, and a fitting. The fitting facilitates an influx of a fluid into the through-bore to push the piston against a first wear assembly received within the mounting block such that the first wear assembly is advanced to reduce a gap with respect to a second wear assembly associated with the second bearing arrangement and retain the moldboard slidably between the first wear assembly and the second wear assembly.

The present disclosure is directed to systems and methods for operating a grading machine. The method includes (i) receiving information indicating a current position of a moldboard of the grading machine; (ii) determining if the moldboard is moving toward an avoidance zone, and the avoidance zone is defined by a distance from a scarifier of the grading machine; and (iii) in response to a determination that the moldboard is moving toward the avoidance zone, adjusting at least one operating parameter of the moldboard or the scarifier of the grading machine.
