I recently purchased this tractor and am in the process of fixing it up. I have worked on numerous Ford 8N, 9N and Jubilee models, but this is the first MF. I am pretty impressed with it, it is quite a step up from the little Fords. I am looking for an electrical wiring diagram, I purchased the service manual from this site, but it does not include any electrical information. Is there one in the IT Manual that would cover this model? I have looked on the internet, but can"t find the right one. Also, I am not sure how the safety start interlock button is supposed to work, there is a small wire clip shown on some of the drawings I have found, but I am not sure what it does. Also the planetary for the transmission low range is missing, is this something that can be reasonably replaced? I am sure I will have more questions later, but that will do for now, thanks.
