    High pitch whine noise from rear PTO area?

    Hello,

    I have a 16 1025r that I purchased two months ago. I have about 25 hours on it and it runs great. I have a ballast box attached and have only use the loader/forks. (No mowing or shredding). With the throttle low or at near idle, I notice a high pitch noise coming from the rear of the tractor. If I move the loader at all, press the throttle, or increase the engine speed, it goes away.

    This is my first tractor and I am not sure if this is normal or not. I am not opposed to taking to my JD dealer to look at, but I have to borrow a trailer and that makes it a bit convenient. (Not to mention trying to get time away from work)

    Is this normal, or should I be worried, any tips or tricks to check?

    Thanks

    I know the "whining" your talking about. I think your ballast hox is close to capacity and at idle your hydraulics aren't strong enough to lift your ballast. Some people here were good enough to come through with plenty of answers.

    I'm glad you posted this. I had the same question about mine, except mine only makes that whine when it's cold or the machine hasn't warmed up and when there is nothing on the three point hitch. Mainly when I raise it in the conditions above it whines. I was going to record it and take it to the dealer and see what they thought.

    Come to think of it, I think mine does it mainly when it's cold too. I'll have to pay more attention, maybe I just don't notice it after a while, or maybe it does go away once warm.

    I don't know if you have a backhoe, but right now mine is on. When I startup the tractor and let it warm up for a minute, then lift the rear PTO (mainly to lift the mower) it hasn't been doing it since the backhoe is on. Take that off and not have anything on the hitch, huge whining noise!

    I had the same question when I got mine. I'm pretty sure it's the pump/relief valve (fluid returning to the reservoir). It is louder when it's cold but still noticeable when warm. I didn't notice any change after my 50 hour service.
