The bore and stroke of the 285 is 85 x 300mm. Power is the same, 32hp, but at 1100rpm instead of 1200.
The tractor is either an F or industrial N. Note the non-standard pulley, unusual wheels and air start and how tall it is. A 2 stroke, 2 cylinder Fordson is odd enough, but an air start one even more so. A must to have for any collection!
