A vehicle comprises a chassis, a seat, an endless drive track, a rear suspension assembly with at least one slide rail and a substantially inextensible limiter strap extending between the chassis and the at least one slide rail, to limit separation between the at least one slide rail and the chassis. The strap holder is moveable between a first holder position and a second holder position, a position of the end of the limiter strap being different in the first strap holder position compared to the second strap holder position. A control cable is operatively connects the strap holder to a strap adjustment actuator. The strap adjustment actuator is disposed forward of the seat and is operable by a user during operation of the vehicle, the strap adjustment actuator being movable between first and second positions related to the positions of the strap holder.

A carriage assembly includes a primary frame, a first idler wheel mounted to the primary frame, and a secondary frame pivotably mounted to the primary frame. The carriage assembly further includes an idler wheel assembly coupled to the secondary frame and movable with respect to the secondary frame along a longitudinal axis of the idler wheel assembly. The idler wheel assembly includes at least one second idler wheel and at least one third idler wheel mounted to the idler wheel assembly such that the second idler wheel is located between the first idler wheel and the third idler wheel. The first idler wheel is configured to pivot with the primary frame relative to the secondary frame, and the second idler wheel and the third idler wheel are configured to move with the idler wheel assembly relative to the secondary frame along the longitudinal axis of the idler wheel assembly.

A suspended undercarriage assembly connectable to a multi-member frame assembly of a track system includes a beam having a leading portion and a trailing portion, at least one support wheel assembly connectable to the beam, at least one of a leading resilient bushing assembly and a trailing resilient bushing assembly including a bushing having an opening defined therein and being shaped and dimensioned for promoting deformation of the bushing in at least one of a vertical direction and a lateral direction. The bushing is resiliently deformable to permit movement of the beam relative to the multi-member frame assembly in the vertical direction and in the lateral direction, and to resiliently bias the beam towards a rest position with respect to the multi-member frame assembly. A track system having the suspended undercarriage assembly is also provided.

An isolation system for a vehicle having a rear frame attached to a front frame. The rear frame supports a greater portion of a total force applied to the vehicle than the front frame. The isolation system includes at least one isolating device positioned between the rear and front frames. The isolating device supports a portion of the total force applied to the vehicle in a direction in which the isolating devices is positioned. The isolation system includes a force limiting device positioned near the isolating device and a motion limiting torque rod attached to the rear and front frames. The force limiting device limits the amount of load applied to the isolating device above a maximum load. The motion limiting torque rod prevents or limits movement of the rear frame relative to the front frame in the direction in which it is aligned.

A track assembly for assisting in moving a farm implement along a ground surface in a line of travel is provided. The track assembly includes a tilt arm comprising front and rear ends. The track assembly includes a camber arm coupled to the tilt arm such that the camber arm permits the tilt arm to pivot about a first axis perpendicular to the line of travel and a second axis parallel to the line of travel. The camber arm is located between the front and rear ends of the tilt arm.
