1. It will do what you want. Plow
2. You can mount a blower or tiller on it. (and anything else you want)
3. You did the rebuild and you know the owners use and maintenance of it.
4. It seems to have a few memories for you.
So if you want it for your own it might be a fair deal. If you plan on fixing it up to sell, you
could lose your shirt. It's all about what you want. Not what the other guy has.
