Just picked up a 4-150 this weekend at an auction. Dont think I did to bad, only had to give 5 for it and it has eight decent to good tires on it that are 80% or better tread so I figured I bought a set of tires and got a tractor for free. They had it listed as a 74' and I was just wondering if they were correct. SN is 246-781-403 and Model Number is 126-82121. It would be kinda cool if it was a 74' since that would make it a first year 150. Whoever bought it back in the day must have had some money because it is all optioned out. Heat/AC, factory radio, three point, pto, and cast iron inner and dual rims all the way around. The cast iron duals were the biggest reason I bought it, she is weighted for some serious tillage work. Needs some TLC but that old 3208 runs like a top and carries good oil pressure so there is plenty there to work with.
