I'm retired and have an old 15 hp Craftsman lawn tractor that I parked 10 years ago because it became a collection of problems. Recently, I decided to pull it out of the barn and "fix" it. It developed a problem that neither I nor my local small engine fix-it guy could solve. So, I started forum shopping. This is the only one that seemed to provide help for a lot of different tractor problems. So, I joined. So far, it looks promising.
