Ford XX0 hundred series built between 1955 and 1957
8XX indicates a 172ci gas 4cyl engine kicking out an impressive 45-48 or so pto hp, depending on the carb,manifold, and who you ask. ( original carb and setup should be 45.. etc.. )
X2X, stripped down economy version with 4spd trans, NO pto, and NO hydraulic lift.
Note that the tractor could have been ordered as an 820 and then later re-equipped via the dealer.. or re-equipped by a farmer with a frined with a ford 8XX with a blown engine.. etc. Also possible, since the model ID is stamped on the tranny, that the tranny has been swapped around.. etc.
whatcha want to know specifically?
