A track system for traction of a vehicle (e.g., a snowmobile, an all-terrain vehicle (ATV) 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 have various features to enhance its traction, floatation, and/or other aspects of its performance, including, for example, a lightweight design, enhanced tractive effects, an enhanced heat management capability, an enhanced resistance to lateral skidding (e.g., on a side hill), an adaptive capability to adapt itself to different conditions (e.g., ground conditions, such as different types of snow, soil, etc.; and/or other conditions), an adjustability of a contact area of its track with the ground, and/or other features.

An exhaust system for a snowmobile includes a muffler housing, the bottom end of the muffler housing including a muffler exhaust outlet configured to emit exhaust. The exhaust system includes a muffler housing cover spaced from the muffler housing to define an airflow channel therebetween, the muffler housing cover forming a bottom opening. The exhaust system also includes a gas combiner at least partially surrounding the muffler exhaust outlet on the bottom end of the muffler housing and extending through the bottom opening of the muffler housing cover. The gas combiner receives air from the airflow channel and the exhaust from the muffler exhaust outlet to emit a combined air-exhaust stream.

A snow vehicle is disclosed comprising a vehicle frame, a propulsion unit coupled to the frame, and a front ski steered by a steering mechanism. The snow vehicle has a chain coupling the sprocket of the propulsion unit and a chain tensioning device to take up the chain tension. The chain has a chain guide positioned below a lower run of the chain which directs the chain towards an upper run of the chain.

A vehicle comprises a chassis, a seat, a motor, an endless drive track, and a rear suspension assembly supporting the endless drive track. The rear suspension assembly includes a left slide and right slide rail, at least one rear suspension arm being operatively pivotally connected to one of the slide rails and the chassis, with at least one coupling block being connected thereto. A rear stopper is connected to one of the slide rails, the rear stopper being disposed within a range of motion of the at least one coupling block in a first position and being disposed out of the range of motion of the at least one coupling block in a second position. The vehicle includes a control cable and an actuator, the rear stopper moving between the first and second positions when moving the actuator between first and second actuator positions.

A snowmobile comprises a chassis with a front portion and a tunnel, and a power train unit supported by the chassis. The snowmobile further includes a plurality of ground-engaging members cooperating with the power train unit to operate the snowmobile. The plurality of ground-engaging members includes a pair of front skis and an endless track assembly. The snowmobile also includes a front suspension operably coupled to the pair of front skis. The snowmobile also includes a rear suspension operably coupled to the track. The rear suspension includes slide rails and track sliders for engaging the track. The track sliders are comprised of a first and second retention members for coupling with the slide rail. The retention members are comprised of a plurality of recesses where material is removed for light weighting.

A vehicle urging system for inhibiting a vehicle from becoming high centered includes a vehicle that has a plurality of wheels and a bottom side. A track unit is coupled to the bottom side of the vehicle. The track unit engages an object that would otherwise high center the vehicle, such as a rock or the like. The track unit selectively rotates in a first direction to urge the vehicle along the object until the vehicle is clear of the object.
