 4115 Hydraulics or HST Transmission Problem

I own a JD 4115 that I mainly use for mowing with a 60" mid mount mower deck. Today, it suddenly started leaking fluid, dumping red colored oil on the mower deck. As soon as I noticed the problem, I cut the mower off and headed for the my storage shed. This was a massive leak, fluid covered the deck and the sight glass for checking hydraulic fluid was completely dry. It left a stream of oil accross my blacktop driveway.
Checking from underneath the tractor, the mid and rear PTO shafts were dry, so the seals are OK, but the 4" square plate on the bottom of the transmission and the underside of the tractor (directly above the mower deck) was drenched with oil and dripping this red fluid. Also, the two hydraulic lines going to the power steering were very wet and dripping oil from their lowest point. Anybody have any idea as to what is causing the leaking? I haven't attempted to add more trans fluid, but I'm guessing the transmission fluid has to be near empty. The transmission and the three point hitch lift still worked fine. Do I have a bad Hydro Transmission or is this probably a hydraulic line failure? I bought the tractor new and it only has 180 hours. Please advise.

Without seeing the tractor I'd guess you have a broken line or a spin on filter that burst or came loose. Starting the tractor very briefly and watching where the fluid comes from would be the easiest way to find the leak. One caution, don't use your bare hand to feel along a line for the leak, high pressure fluid leaks can penetarte the skin with nasty consequences.
Your comment about "Red" fluid. Your tractor must have something other than Deere Hy-Gard fluid. Unless they have changed lately Hy-Gard has never been red. I doubt the use of an approved non Deere fluid would have caused the leak tho.
Frank.

It is JD Hy-Gard oil in the tractor. It just appeared to have a red/brownish tint when I viewed it in the bright sunlight. Have not yet attempted to start the engine and search for a leak, but will do that. Does anyone know what hydraulic lines/connections are hidden behind the panel between the instrument panel and the floor pannels? If there are fluid lines hidden in there, maybe I should remove the panels first.

I haven't been under the hood of a 4115, but I'm sure there are steering lines and perhaps others behind the dash.
Maybe start it for a bit to see if anything does come from under there. If nothing is coming from there then probably no need to remove the panels.
Frank.

You will have to remove the mower deck to get to the bottom of this problem.

There are at least 7 metal hydraulic lines under there plus 2 flex hoses for the steering and a filter canister that could be leaking.

That said, odds are that a fitting has come loose and just need tightening. The only oil leak I have had with mine was last winter on the snow plow and I fixed it with a wrench.

Also, your tranny sump holds about 4 gallons. That would be a BIG puddle.

I also own A JD4115. The first thing I would check would be the transmission filter. When I first mounted my 72" mmm, I had to adjust mower deck lift linkages to not contact the trans. filter. If, per say, the mower deck was raised/forced up by an obstruction. The filter may have be damaged and leaking. I hope this helps. Let us know what you find.

Thanks for the suggestions. I have been out of pocket for a few days, but will check out the lines and filter next week, and let everyone know what I find.

 4115 Hydraulics or HST Transmission Problem

I removed the cover below the instrument panel and discovered the leak after starting the engine and moving the lever to raise and lower the three point hitch. Hydraulic oil started leaking from one of the two lines going to the power steering. Two hydraulic fittings attach to a casting and the inner line fitting was the leaker. I did tighten the fitting (at the end of the hose, but it still leaked when I restarted the engine and cycled the three point hitch again. I probably could have accomplished the same by turning the steering wheel, but did not think to do that. I did not want to overtorque the fitting, so I am seeking info on how to seal this leak. Any suggestions?
Fortunately, it is only a hydraulic line and not the transmission.

Assuming it's a typical JIC-type fitting, it could be a bad line fitting or it could be the nipple that the line connects to that is in the steering unit. Typically they use an o-ring type of seal on the base of the nipple which can blow out or if the nipple has a jamb nut and washer which presses down on the o-ring, the nut could have backed off and the o-ring moved. A lot of times the machining of the hydraulic unit's orifice was shoddy and has burrs. If the burrs are not smoothed or removed, the new o-ring will be destroyed in no time and repeat the leak.

Thanks for the input. I examined the hose fitting connection and there is no O ring. The nipple has a deep recess to receive a boss that is seated at the bottom of the hose nut. I'm thinking 37 degree JIC, but there are so many variations of these things, I'm not sure.
I guess it is time to take this hose to a NAPA or JD dealer and see what they recommend. I was attempting to avoid paying a small fortune for the parts at the JD dealer.
