The invention relates to track systems 14, 14' that may be used to convert steerable, all-wheel drive construction equipment to steerable, multi-track construction vehicles 10. A preferred embodiment of the track system 14, 14' includes a frame 60, 182 having a reinforcing enclosure 150, 230, a plurality of track engaging rollers 82-86, 202-206, a sprocket 102, 214, and an endless track 76, 198 operatively connected to the frame 60, 182. Tension on the endless track 76, 198 is maintained with two tensioning members 170, 244 operatively connected to the forwardmost roller 82, 202. The track system 14, 14' preferably includes a limiting apparatus 300 that is configured to restrict the rotational movement "r" of the frame 60, 182 relative to a vehicle axle 16 to which it is attached. The limiting apparatus 300 has a first component 40, which is associated with the vehicle axle 16, is configured and arranged to interact with a second component 262, which is associated with the frame of the track system 14, 14'. Preferably, the limiting apparatus 300 is adjustable such that the range of rotational movement "r" can be varied.
