Old tractors are the way to go. I would not be able make due with out my Ford 640. I would have to agree with Gabel about having power steering the 640 is a nice size tractor but can be a bear to steer. Here is a great web site for info, manuals and parts. I have purchases many parts from these folks in the past with out any problems.

Good luck. Karl Hines
