Posted about M PTO a bit ago - now its got me wondering. My parts book shows both the flat PTO cover and also the hump back. It says the humpback is optional. I'm hearing otherwise. When did IH change from one style to the other? One of the tractors is a 49 and the other is a 50, but you know how much things change on a tractor over the years. The 49 is my loader tractor and has been worked pretty hard in its life so there are likely many replacement parts there. The 50 is a parts tractor but more likely to have what it came with as I don't think it was worked nearly as much. It has the humpback.
Since they seem to engage the PTO differently I figured that switching them out might not be a 5 minute deal. I don't use the M for any PTO work other than running the mixer grinder. Maybe it will last a while longer. The seal on the flat cover doesn't seem so easy.
