Hi it is worth a fair bit in the right place Im gonna guess $5000+ in North America to the right collector. And maybe $15.000+ back in the U.K.
That tractor was converted by county Comercial cars in the U.K. They are the company that made the equal sized front wheel assist tractors, based on the fordson Majors( super 4 &6) and later ford 000 series county tractors (654, 954,1004 1124,1164). It stands pretty tall, is 2 wheel drive and has drop boxes on the rear axles and long spindles on the front axle? Basically it is a tractor for high clearance work like spraying beans or other tall crop work. there aren't too many of them around so would be a good find and certainly doesn't want scraping. The tractor parts are pretty easy to find. The conversion parts might be a bit of a custom build, Unless there is another one laying around in the bush. Good luck and sorry i can't be more firm on pricing it's a bit to unique to be accurate. As they don't come up to often round about. Regards Robert
