I have never used a track machine, but I know where one is, if needed. I don't own one with tires either, but have several hours in several models. I liked the JD best, but with more practice, the Cat with twin joysticks would probably have been more efficient.
Like any tool, you keep finding more you can do with it. If I only had three toys to ranch with, a skidsteer would be number three. My list is one stock trailer too short, but I'd figure something out.
