Yours looks nice, I just moved my 950 over to the dealer for a consignment sale. Note that the dipstick in the yellow cap is to measure the 90wt in the front axle. Make sure when filling to thread the cap all the way into the axle and seat the O ring on the housing, remove and read the level. If you are measuring from the top without threading it all the way in you will overfill,If you don't, measure from the top. you will have the leak pictured, you could just have a overfilled axle in front. Those seals aren't to hard to replace, parts are available, not cheap though. There is a rubber coated sleave with the seal that must be replaced as well. First I'd check the level, drain excess out if necessary, and clean those joints. See if the leak returns. If it does see a JD dealer for the parts. Med wrenching skills needed to replace this one.
