i have an old farmall , international tractor seat and mounting box, it has a shock absorber and a good seat spring. not sure what it came off of, maybe a 450 or 560, something from the late 1950s or early 1960s? it will fit many makes and models of farm tractors. i wire brushed it, then put a coat of rust converter on it, and painted it. as you can see the seat pan is rusted, but still sturdy. it could be easily repaired with some fiberglass cloth. if you just want the seat, without the new tractor seat pad, i will sell it for 100.00, cash only. thankyou for looking.
