Hydraulics lift bush hog OK, but if I turn off the tractor or even push in the clutch it drops in a couple of seconds. What is the most likely valve or area that is leaking.Thanks

I just rebuilt my 48 8N, replaced the safety valve and put in a new oring piston to replace the ringed piston. Works just great now. I ordered all my parts from don at 8N's. Good luck. It is not hard to fix it if this is the only problems.
Worst about the entire job is the weight involved in removing the top of the case and getting the selector shaft in the right spot. Good luck

In other words, you hog will stay up as long as the pump is running. I would suspect a leaking cylinder is causing this. Remove the side cover and look for hydraulic fluid coming from above when the pump is not running. Of course the lift has to be up with weight on it..
