A construction vehicle includes first and second track assemblies. The track assemblies each include an inner portion, and outer portion and a middle portion between the inner portion and the outer portion. An adjustment mechanism is pivotably coupled to the middle portions of the first and second track assemblies. The adjustment mechanism extends and retracts along a width axis to adjust a distance between the first and second track assemblies. The width of the first and second track assemblies can determine an overall width of the construction vehicle. |
