MOE,
I have had 2 Mini-Chief Stump Grinders over the years. I had very good luck with them. They aren't made any more but most parts are available from bearing companies. Nice two cyl diesel and plenty of power. They do tip over pretty easy. Always go strasight up and down hills slowly. Only 36" wide, very nice for going throught a garden gate. I had a job at the local airport to grind about 300 small stumps 3 to 6". I did it in about 4 hours. The best thing is I didn't have to get off the machine. Give me a call at 207-939-5469 if you want more info. Steve Smith, Falmouith, Me
