TN75 hydraulic leak

[yeehaw]

TN75 4wd has started to have a hydraulic leak coming from the pivot point of one of the 3pt arms (where it attaches to the tractor). tried to attach a pic showing the fluid coming out. what is the culprit here and how big of a chore is to fix (is there a gasket that has failed on the inside...or something else)

I changed mine out this past spring. If I'm not mistaken -- Steve help me out as well. Took me about 1hr 15 min to do the repair! I think all the TN series tractors have this problem!

It's a common problem to all lower link draft sensing systems like that on the TN. John Deere has the same system and same problem.
15 minutes is about right for the actual repair after draining the hydraulic oil and everything goes well. I have had the retainer bushing and/or the lift arm ball rust on the shaft which takes quite a bit longer.

15 minutes? Your'e kidding, right? Or maybe you are one of the guys that wrote the flat rate manual.
Maybe 15 minutes after draining the oil, removing the lift link and removing the bushing/seal housing from the tractor. And not including the time it takes to reinstall the housing, lift link and oil.
