"Betsy" is a 1951 8N (side-mount distributor). The 3-point USED TO be just fine ... then would "get wierd" at times. Low lift power / all up (with little control) or all down, but if I "tapped" (OK, hammered) on the case, it would free up. I suspect something "sticks" ?? I'm gonna change hyd oil .. it's got "gear oil 80-90" as per specs, but I've heard other opinions (PTO shaft does leak a bit -- I'd hate to go too light). It used to have to be above 30 degrees for the Hydraulic to work .. cold = thick. (but I got a new NH TC-33 a couple years ago, so Betsy just does light duty now .. and the TC-33 does the plowing and mowing)
In short, what's with the 8N's 3 point? JDL

I don't know where you are tapping exactly and that might help to answer your question. In the top of the case is a piston simular to a car engine that might be worn enough to get stuck or you might just have a sticky valve. To install lighter oil will only find more leaks for you then you had before. The system is designed for gear oil and I'd stick with it. ....

Art, Thanks. As to WHERE ... I think I used to "tap" (actually pound) on the sides of the case, but it won't "free it up" at all any more. I keep thinking I'll get time to tear into it, but never seem to find the time -- OR the space to tie up. I also keep thinking sometime I'll drain it, put in some cheap detergent oil for a while, then drain it again and put in the proper gear oil. Maybe that'll help. "Betsy" probably has more sentimental value than $$ value. My wife says Betsy is the "Tractor Emeritus" since we got the NewHolland. (I spent a lot of my youth on 8N's mowing & raking hay .. and cleaning feed lots) I hate to spend to have some dealer or shop rebuild the hydraulic on a 50 year old tractor. Now, if there's somebody out there who knows and loves old Fords -- within 2 or 300 miles of the Omaha area -- and would like a little project this winter .... :-) I'd be tickled to talk to them. Jay ....
