Wish I could help, but I have no idea. I just ordered an IT service manual for my MF1010. Total $26.50 including shipping, but worth it. There are no online downloadable manuals for it, so just bought.
I just broke down and ordered a Kubota parts manual... Kinda pricey but there are no cheap ones available for that particular tractor. The service manual is extra but I think if I have the parts manual with the exploded drawings I can pretty much figure things out. I think once I pull the cowling off the back most will be easy to address.
