I have a question about my Kubota 7510 hst. When I am in 4wd I notice a faint howling or moaning sound in the front of the tractor when I turn the wheels kind of sharp. Is this normal or is there somthing wrong or low on gear oil or somthing? Best to look into it now in case it gets worse. Thanks in advance.

It's always best not to turn shaply in 4wd on a hard surface. If you are on pavement, keep your turns to as wide as possible. The moaning you are hearing is the 4wd trying to compensate for the differential turning radius between the 2 wheels. I think the tractor is trying to tell you something.

Always a good idea to check and keep the fluid levels clean and full. ....

YOu might want to check your air pressure on you rfront tires as well as rear for balance of the driveline. When off the four wheel drive doesn't engage or disengage well. ....

My blue doesn't "howl" but does groan when on pavement or hard-pack when the tire pressure is off especially on the rear tires. And I agree with Art and beagle; it's telling you something. When it's on loose dirt it's not as noticeable as the tires can slip and overcome any rotational differences the driveline is seeing. Either way is saps power and any sort of driveline bind just isn't good for the life of the tractor ....
