A snow wing assembly for a machine includes a moldboard and a linkage assembly. The linkage assembly includes a first linkage, a second linkage, a third linkage, and a fourth linkage. The first linkage is coupled with the moldboard. The second linkage is pivotally coupled with the first linkage at a first outboard end of the second linkage. The third linkage is pivotally coupled with the first linkage at a second outboard end of the third linkage. The fourth linkage is coupled with the machine and pivotally coupled with a first inboard end of the second linkage and a second inboard end of the third linkage. The third linkage is selectively adjustable to vary a distance between the second outboard end and the second inboard end for tilting the moldboard.

In some implementations, a lift assembly for a moldboard of a snow wing assembly of a motor grader may include a first lifting mechanism mechanically coupled to an undercarriage assembly of the motor grader. The first lifting mechanism may be configured to lift the moldboard of the snow wing assembly a first portion of a bench height associated with the moldboard. The lift assembly may include a second lifting mechanism mechanically coupled to the first lifting mechanism and the moldboard. The second lifting mechanism may be configured to lift the moldboard of the snow wing assembly a second portion of the bench height associated with the moldboard.

In some implementations, coupling system for rotatably coupling a moldboard of a snow wing assembly includes a hinge for rotatably coupling the moldboard to a linkage assembly to enable the moldboard to rotate in a first rotational direction, the hinge including a plate having a first face and a second face. The plate includes a first passageway extending between the first face and the second face to facilitate lubricant being supplied to a first interface between the plate and the moldboard. The coupling system may include a pin extending through the moldboard and the plate to rotatably couple the moldboard with the hinge. The pin enables the moldboard to rotate in a second rotational direction about a rotational axis defined by a body of the pin, and the body includes a second passageway extending from a bottom portion of the pin to an outer surface of the pin.

A plowing system is removably mountable onto a vehicle in order to provide the vehicle with lateral plowing capability along a given lateral range of the vehicle. The plowing system includes a mounting assembly, a plowing assembly and corresponding plowing component. The plowing system also has associated first and second actuating assemblies cooperable with one another so as to selectively operate the plowing component between retracted and deployed configurations, and so as to provide the plowing system and associated plowing assembly and corresponding plowing component with an increased plowing resistivity within the lateral range of the vehicle, due to a combined effect of the first and second actuating assemblies. A corresponding vehicle is provided with such a plowing system.

In some implementations, a lift assembly for a moldboard of a snow wing assembly of a machine may include a lifting mechanism, coupled to an undercarriage assembly of the machine, configured to lift the moldboard of the snow wing assembly to a bench height associated with the moldboard. The lift assembly may include a hinge rotatably mounted on a bar of the lifting mechanism, wherein the bar defines a first axis, and wherein the hinge is rotatably coupled to the moldboard about a second axis. The lift assembly may include a first rotational mechanism, coupled to the lifting mechanism and the hinge, configured to rotate the hinge and the moldboard about the first axis. The lift assembly may include a second rotational mechanism, coupled to the hinge and the moldboard, configured to rotate the moldboard about the second axis.

A plowing system (1) for removably mounting onto a vehicle (3) in order to provide said vehicle (3) with lateral plowing capability along a given lateral range (5) of the vehicle (3), the plowing system (1) including a mounting assembly (7), a plowing assembly (9) and corresponding plowing component (11), as well as associated first and second actuating assemblies (15, 19) cooperable with one another so as to selectively operate the plowing component (11) between retracted and deployed configurations, and so as to provide the plowing system (1) and associated plowing assembly (9) and corresponding plowing component (11) with an increased plowing resistivity within the lateral range (5) of the vehicle (3), due to a combined effect of the first and second actuating assemblies (15, 19). Also described is a corresponding vehicle provided with such a plowing system (1).

A support assembly for a wing moldboard includes a rearward base securable to a vehicle to pivot about an upright axis, lower and upper booms, a lower-boom mechanical actuator, and a rotation member. The lower boom is pivotably securable to the rearward base. The upper boom has an upper-boom proximal portion pivotably securable to a distal end portion of the lower boom. A lower-boom mechanical actuator drives the lower boom to first and second positions. A rotation member has a proximal portion configured to be operatively engaged with the rearward base, and a distal portion operatively engaged to pivot the upper boom with respect to the lower boom when the lower-boom mechanical actuator drives the lower boom between the first and second positions. A further support assembly for a moldboard includes a support-wheel assembly including a travel-angle frame, a travel-angle actuator, a spindle mount, a spindle, and a wheel-height actuator.

Systems and methods for operating a grading machine. The method includes (i) receiving information regarding material on a surface, and the grading machine is configured to travel on the surface and move the material on the surface; (ii) determining a set of parameters for operating the grading machine, and the set of parameters include an articulation angle of the grading machine and a moldboard angle of a moldboard of the grading machine; and (iii) positioning a snow wing and the moldboard of the grading machine based on the set of parameters such that the snow wing has a predetermined spatial relationship with the moldboard.

A wing plow system can include a wing plow assembly with a first moldboard assembly and a second moldboard assembly. The first moldboard assembly can include a first moldboard configured to extend away from a vehicle toward a trailing end of the wing plow assembly. The second moldboard assembly can extend from the first moldboard assembly toward the trailing end of the wing plow assembly. The second moldboard assembly can include a second moldboard slidably supported by the first moldboard to be slidable between an extended position and a retracted position, to move the wing plow assembly between an extended configuration and a retracted configuration.
