A track system for a vehicle has an attachment assembly mountable to a chassis of a vehicle and defining an attachment-assembly-pivotable connector pivot axis; a track assembly including a support frame disposed laterally outward from the attachment assembly, the support frame including a leading frame assembly and a trailing frame assembly, each frame assembly including a frame member connectable to the attachment assembly pivotable connector and a frame-suspension pivotable connector; at least one wheel-load-bearing connector, and at least one idler wheel being at least indirectly connected to the frame member via the at least one wheel-load-bearing connector. The track system further has a sprocket wheel, an endless track, and a suspension assembly having a forward suspension pivotable connector, a rearward suspension pivotable connector, and leading and trailing suspension members pivotably connected to the forward suspension pivotable connector and to the rearward suspension pivotable connector, and to a link.

A method for mounting a track assembly to a vehicle comprises: pivotally connecting a frame of the track assembly to a distal end portion of an A-arm of the vehicle for permitting rotation of the track assembly about a steering axis; inserting a fastener through a fastener aperture defined in the distal end portion of the A-arm; and fastening an anti-rotation device of the track assembly to the distal end portion of the A-arm with the fastener, the anti-rotation device being connected to the frame. A suspension and track assembly for a vehicle is also disclosed.

A tensioner for adjusting a tension in an endless track of a track system is disclosed. The tensioner includes a resilient portion and a wheel connecting portion. The resilient portion is connectable to a frame of the track system, the resilient portion being oriented generally vertically. The wheel connecting portion is pivotally connectable to the frame of the track system, is connected to the resilient portion and is configured to connect to an idler wheel assembly. A track system having the tensioner is also disclosed.

A crawler traveling device includes a first wheel; a second wheel spaced from the first wheel; a support frame that supports the first wheel and the second wheel; a third wheel disposed above the support frame; an endless crawler wound around the first wheel, the second wheel, and the third wheel; and a vehicle-height changing mechanism that changes a position of the support frame in the vertical direction with respect to the third wheel. The vehicle-height changing mechanism has an actuator that is capable of contracting in the vertical direction and that changes the position of the support frame in the vertical direction with respect to the third wheel.

A work machine may include an electric motor, an idler wheel, a drivable track engaged with the idler wheel, and an actuator that is electrically powered by the electric motor and configured to move the idler wheel to adjust the tension in the drivable track based on the torque output of the electric motor. The work machine also includes a controller configured to automatically control the electrical current input to the electric motor based on one or more monitored control factors associated with the work machine.

A snowmobile extends along a longitudinal axis and includes a frame, a powertrain coupled to the frame and a track operatively coupled to the powertrain, the track having an upper run and a lower run. The snowmobile includes a rear suspension having at least one slide rail having a hyfax defining a plane, at least one front idler wheel in contact with the lower run of the track, at least one center idler wheel positioned adjacent the at least one front idler wheel, and at least one rear idler wheel positioned adjacent the at least one center idler wheel, and wherein the positioning of the at least center idler wheel is configured such that the at least one rear idler wheel is positioned at an angle relative to the plane having a value that is greater than zero.
