So far you have posted questions about an old Ford, a Bolens, a Case, and now an older Sears. Obviously you are looking at large lawn mowers or what is called the garden tractor class of machine.
You might have better responses if you posted down the message board in the threads that are more focused on these garden tractors.
Just a word. An old Ford or Bolens or Case Ingersoll were all fine enough garden tractors. They are getting quite long in the tooth. I assume you are looking in this direction because you are on a budget of a something less than 800 bucks, maybe less? In this range, you are going to find machines with many, many hours of use. I won't say worn out, but just be careful.
Best wishes on your search
