Supers have a restyled radiator cowl, a slightly larger engine, and probably gearing for
a slow-speed rototilling. About 1962.
The Standard Dexta continued as well. This one looks like a Standard. Can't tell age. Serial number is vertical on the bell-housing flange where it mates with the engine.
The only problem that bothers me is the very difficult manner of mounting and dismounting.
Chances are it's a diesel. Gas hoods have about a 4.00 inch extension, and I don't see that. Gas/petrol are quite rare and probably worth more.
I would be reluctant to pay more than $1000. Perhaps $500 to $1000 more if gas.
With cosmetics fixed up and new tires, you would find buyers at about $3000. They are nice collector tractors because of small size and weight, easy to haul to shows.
All Ford and Ferguson equipment should work.
