So after checking the hydraulic oil the other day and noticing that it appeared to be a diifferent color (level was ok) changed the oil and filter out and it is now whining pretty loud at start up...everything works, loader, 3pt...and after about 20 secs the whining noise stops. It was not doing this before and I had only noticed a whine at start up when it's really cold (it was 95 today)... And thoughts? Bout to do some googling and go back to the manual...
