I have a New Holland TC40DA. I recently took it in for a 500 hour service and a PTO issue. The PTO was still strong, but would have to spin up, so I had the clutch rebuilt. When I got the tractor back I did about 30 minutes worth of work with the backhoe, and then the next weekend took the tractor and bush hog and cleared some light brush for my brother in law. The tractor is equipped with a front end loader and I used it to flatten some dirt and remove brush and saw that the right FEL cylinder was leaking at a pretty good rate. I checked and the seal was coming out in tiny shreds. I checked the left cylinder and saw the same tiny shreds, but not and bad and it hadn't started leaking. I quit working and loaded the tractor up. When I got the tractor home I detached the FEL, and noticed that my HST filter was leaking. I ended up losing about a gallon and a half of hydraulic fluid. To complicate matters, I checked my oil, and the oil is over full. The tractor was running fine but judging by the dip stick it is significantly over filled. I'm not familiar with the way my hydraulic system works and am somewhat concerned that the oil system may be full of something other than oil. For what its worth, the substance on the dip stick appears and smells like oil.
Does anyone have any ideas on what could have caused these issues? I plan to remove and replace the hydraulic filter, remove the excess oil and then test to see if the oil system overfills again or the hydraulic system experiences other problems. This tractor should have a hydraulic overpressure device shouldnt it?
