I ordered the camoplast tracks from a company named ATV Tracks in Spokane WA. Camoplast is a rubber track. The owner, Gary was very enthusiastic about the capabilities of tracks in snow. I have a friend who put tracks on his 4-wheeler to drive in the woods of Wisconsin in the winter and he can drive up steep hills and drive over deep snow. I was not aware that tracks existed for atv's or utv's and my main disappointment in my Kubota 900 had been poor capability in mud and snow. Hopefully the tracks will solve that.
