not to steal the thread, but my dad inherited a riding mower from his dad, its an old Jacobson which apperantly my grandfather purchased used in the 1970's at which point it was already 10 years old... Nothing like a 40 some odd year old mower that still runs and cuts grass well today. it has a 7 horsepower briggs and straton motor. The electric starter doesnt work anymore, but you can pull cord it

Im sure that your mower only needs some minor work.
