Photo #10- See The New Ford Tractors - The line that's GREAT for '58 - Coming Nov 15th!
We have determined that my 1958 851, SN 1002 (the second tractor built after the change from X00 to X01 series), was assembled Sep. 30, 1957. So it appears that Ford started shipping them to dealers in early Oct, 1957 and the dealer was probably supposed to "hide" the new tractors until Nov. 15.
