I have am old Scotts lawn tractor i bought about 20 years ago. It runs great but it hasn’t cut the lawn well for two summers. I think I need one blade, maybe both of them, maybe new belts also.
I love the tractor, but don’t want to spend a lot of money on an older machine. Is there some metric to use to determine if a repair an old machine makes sense, or maybe some age limit to consider before buying a new one?
