Hello and thanks in advance for your insight. I have an 861 Diesel that I've owned and used for the past 30 years mostly to mow with. This year I had to replace the clutch because of oil getting through the input shaft. I replaced seals and bearings and clutch. Also replaced the input shaft housing and bearing and seal. At any rate after about 10 hour of use, and no leakage at all, the hydraulic lift quit working, with no fluid on stick. After a little search, I found that my transmission is now way overfull. Can someone tell me how this happened and what I have to do to get it fixed? Stumped in Oklahoma!!
