I didn't read all the responses so this may have already been posted.    Don't buy some old piece of crap because it's cheap and goes down the road.   You'll hate that thing until you sell it.     Compare a good clean 100 horsepower tractor that you want to the price of a similar new one.   Then, raise your bid even if you have to borrow part of the money.    There's a chance you'll have the right tractor the rest of your life so a couple extra grand means nothing.
