I am somewhat familiar with the 6610 and have run one quite a few hours. I have run across an ad for a 6640. 2 wd, cab/air(supposedly working) claiming 2500 hrs. Pics of it look nice, with good paint(fresh paint always worries me) and decent looking rubber. They list it as an 87 hp tractor. What are the basic differences in the 6610 and the 6640? Any big problems with them.
