CNKS: As I said before, I know very little about the 404 or 2404. My son picked up this IT manual called IH-21, it indicates at top of page it replaces IH-9, IH-12 and IH-14 and that one should destroy these three. What I find unusual about this book, it is not dated. Thus in relation to dates you are quoting one really has no idea when IH-21 was printed. I am new to IT manuals, had never seen one in my life until 5 years ago, after coming to YT and seeing print about them. When I farmed I always had operators and service manuals put out when machines were new. When did these IT manuals come about? What is the history of them? I see you can get them for different makes of tractors as well. The main reason I questioned the live pto was the indication in this IT manual that 404 rearend and transmission are basically 200, 230 and 240 technology. It shows the option high-low gear box bolted to front of transmission. They indicate same gear box is used for the foreward-reverse option. One can see the torque tube would need to be larger than on the 240 to go over this gear box. It also indicates tractor must be split between torque tube and transmission to access this gear box. My thoughts are it would require a major redesign to convert that 200, 230 and 240 rear end and transmission technology to live pto. One must remember also, by early to mid 1960s IH were clearly trying to move all small tractor production to Europe. We started getting the British tractors here in Canada by 1956 or 57. They were diesel, live pto, turned more hp than a 230 and sold for less money. Other than row crop work our small row crop tractors were doomed. You in the US started getting this British technology even though it was assembled at Louisville, using some US manufactured parts. British didn't like our small Farmalls, I guess they are affraid of height.
