Ya , never seen it on a Sw48 . Best option would be to pickup a J5 or Ram Skidder and 75 percent of the running gear from a SW48 will interchange to them , you end up with 16 in grousers. There not really a Cat , I've been stuck on level ground with my J5 in 3 feet of powder. Muskeg , much better , but not a cat either , working in the bush or hauling loads they were designed for that.
