SOURCE: IJohn Deere whinning noise
Is the device that lowers or raises the loader a hydraulic piston type device, or more of a hydrostatic type device? Whining noises are not uncommon with hydrostatic devices...

Im sorry, I thought you said you changed the oil. My thought was that perhaps the hitch might have bled down during the oil change. That happens occasionally with the tractor I service at work.
I hope you find your trouble. If you could let me know the answer, id appreciate that.

You may need to do a compression test on the engine to confirm whether or not the head-gasket needs to be replaced,that's where i would start if the thermostat is not the problem and the hydraulics are not loading up.Check for oil in the radiator or anti-freeze in the oil as well as for white smoke out of the exhaust,all are indicators of a bad head-gasket.
