Vehicles, systems and methods for providing articulating two section vehicles with tracks, and a front body attached superstructure with telescopic forklift, for use on all terrain condition applications. The vehicle can include front and rear track assemblies that can tilt up and down while traveling over different ground surfaces. Each of the track assemblies can have rotatable articulating/oscillating track wheels which can traverse different contoured surfaces. The right and left tracks on both the front and rear track assemblies can separately extend outward and inward from underneath the vehicles to add stability to the vehicles. The cab can be raised and lowered to add greater visibility for the operator. Hydraulics can be used for raising and lowering the extendable boom and operator cab, as well as controlling the body articulating hinge, the articulating tracks and the tilting controls for the front track assembly.

A dive-resistant suspension for a snow machine having a ski assembly and a body has a swing arm and a resilient member that biases the swing arm downward relative to the body. The swing arm has a first rigid linkage and a second rigid linkage. The first rigid linkage has a first pivot point connected to the body of the snow machine and a second pivot point connected to the ski column. The second rigid linkage has a first pivot point connected to the body of the snow machine and a second pivot point connected to the ski column. The swing arm defines a travel path of the ski assembly as the swing arm moves between an operative position and a retracted position. In a first portion of the travel path, the ski assembly moves from the operative position forward and up relative to the body of the snow machine.

A track system for traction of a vehicle, such as an all-terrain vehicle (ATV), an agricultural vehicle, etc. The track system comprises a track and a track-engaging assembly for driving and guiding the track around the track-engaging assembly. The track system may be configured to facilitate adjustment of certain aspects of its operation, including, for example, how it is positioned and/or can move relative to a frame of the vehicle, based on one or more factors, such as, for instance, a user's preferences (e.g., riding style, desire to feel the ground, etc.), an environment of the track system (e.g., a profile of the ground, such as a slope or steepness or a levelness of the ground; a compliance of the ground, such as a softness or hardness of the ground, etc.), a state of the track system (e.g., a speed and/or a direction of motion of the track, etc.), a state of the vehicle (e.g., a speed and/or direction of the vehicle, etc.), and/or any other suitable factor. For instance, the track system may comprise a control mechanism configured to adjust an anti-rotation device that is configured to restrict movement of the track system relative to the frame of the vehicle. The control mechanism may be configured to adjust the anti-rotation device in response to a command, which may be input via a user interface or automatically generated by a controller.

A method for operating a milling machine is disclosed. The method includes receiving an input identifying a leg of a plurality of legs of the milling machine. Further, the method includes determining a height of the leg based on the receiving of the input identifying the leg. The height of the leg being determined based on position data of the leg. The position data being obtained by a first sensor. Further, the method includes determining, by the controller and based on the determining the height of the leg, that a height of other legs of the plurality of legs is to be adjusted. Thereafter, the method includes adjusting the height of the other legs of the plurality of legs to the height of the leg. The height of the other legs being adjusted based on the determined height of the leg.

A lift apparatus is provided for use with a vehicle comprising a first frame and a second frame. The lift apparatus comprises a spindle, a bearing, a cylinder, a snap ring, and a bearing retainer. The spindle is configured to be attached to the second frame so as to extend therefrom in spaced apart relation to the first frame. The bearing is positioned on the spindle. The cylinder is configured to be attached to the first frame and is attached to the second frame to move the first frame relative to the second frame. The cylinder is positioned on the bearing such that the bearing enables movement between the spindle and the cylinder. The snap ring is attached to the spindle. The bearing retainer is positioned on the spindle between the snap ring, and the bearing retains the bearing on the spindle.
