Good morning folks, I was looking at a discussion about the different ways to tell what old Ferguson you may have and to my understanding the TOs are built in the US and Canada and the TEs are from England. Ok I got it, the discussion went on to the difference between TO-20 & TO-30, so the 20s have the oil filter inside the oil pan and the 30s are outside the engine. Ok I got that too. I have a inside oil filter (TO-20) a dash with a air filter vent (TO-30) and 19 spline axles (TO-30 Im assuming) my data plate is completely unreadable. Any ideas of what this thing actually is? Its challenging ordering the right parts [/i]
