It was Ford's attempt to compete with the JD 15 speed power shift. CIH went to an 18 speed with the same era Magnums, and when JD came out with the 7000 series, they offered a left hand reverse on the 19 speed. We had an older Ford TW20, solid tractor, but local dealer wasn't much for parts and service. That's a deal breaker, no matter what color you like.
Were the ford guys not embarrassed, having no pick up hitch, or no stabilizers?, bit backwards, compared to a 160/90 or a 1255, then there's the 540/1000 pto selection!.
