Whining noise coming from front of tractor, can't seem to identify the source

STx · Aug 13, 2016

I've been all over it a couple of times and can't find anything that could be causing this. I jacked the wheels up off the ground and ran the tractor like that and couldn't get the noise to recur that way. The only way it happens is actually moving and it comes and goes. I'm thinking that it's probably the HST transmission, which would mean splitting the tractor. I don't have the facilities or equipment to do that so, it'll have to go to a shop.

So my question is this, if it's the HST, will I save any money or potential damage to other parts of the tractor by taking it in now or should I just run it until it dies and deal with it then?

Did you try the metal shield rubbing on the front driveline? I recall several members had that problem and cured it with a slight bend of the sheet metal. Your vid COULD sound like tin rubbing on something slowly. The turning doesn't jibe with that explanation of course, unless the axle moves slightly in its bushings.
