I just bought a Kubota L3010 4WD w/ GST with 32 hours on it. I really like the tractor but when in lo gears ( 123 )
there is a constsnt " whine" as I move foward, it seems to be coming from the transmission. Does anyone else hear this with there 3010? Thanks, Tom Smith

It's hard to understand your "whine". Gears 1,2,3,4 are all in one range, is it only when using the loader? ....

I can't say what is normal for the tractor. I imagine the TX is similar to my Ford 1710 that has four ranges that aren't synchromesh and three forward and one reverse synchromesh gears within each range. I haven't noticed anything I'd describe as an abnormal whine from mine. Of course, I did have a LaSalle TX in my '37 Olds coupe that sounded like a threatening dog when in 1st gear, so maybe I'm just used to TX gear noise.
Similar to Art, I wonder if the whine is in first through third in all ranges but never in fourth, or if it only occurs those gears when in low range. I think Art also is asking if the whine could be hydraulic noise. The location of sound coming from equipment can be tricky. Hydraulic oil makes a distinctive sound when it goes through control or relief valves. Power steering also makes a distinctive sound when it's active. Hydraulic sounds are different than bearing and gear noises.
If you're very new to tractors, it's a good idea to get a sense of the different sounds that are normal. These sounds indicated something is wrong if they aren't present. Listen to the control valves when operating the loader. Run the loader curl to the end of its travel and hold the valve for a few seconds--the relief valve should open and a 'scream' can be heard (A tractor shouldn't be operated for prolonged periods when the relief valve is open). An overloaded 3ph also can open the relief valve. Turn the steering wheel and listen for the PS. Most power steering systems are active as long as there is pressure on the steering wheel--whether or not the wheels are actually turning.

OK, the "whine" is present when moving foward 1n 1,2 or 3. No load or implements attached, just driving foward.
Its very noticable behind me in the area of the 3 point hitch. And yes, I am fairly new to tractors, I only know my JD 755 did not have this type of noise. Thanks ....

From the location, the differential, 3ph and pto drive seem to be the main possibilities. I don't know where the relief valve is located on the tractor but that's another possibility (the relief valve on my Ford 1710 is near the engine).
First thing is to eliminate some possibilities. I don't know what sounds are normal for the tractor, but maybe somebody will comment. Second is to eliminate the hydraulic system as a possibility. I'm assuming the 3ph lifts, lowers and stops in neutral normally and the pto is disengaged. I wonder if there's a possibility the whine is heard only when the 3ph is fully raised. A properly adjusted 3ph will go out of lift mode into neutral before the 3ph reaches the physical limit of it's upward motion. An improper adjustment can allow the 3ph to remain in lift mode at the top of its travel. The result is that the system relief valve will open and a 'squeal' can be heard. The sound would be the same as if a loader valve was held open. The relief valve sound may not be apparent at low idle rpm's.
Another way of distinguishing hydraulic from gear noise is engine rpm vs. ground speed. Relief valve squeal may not be very noticeable at low engine rpm, but hydraulic noise should be independent of forward motion. I wonder if increasing the rpm while the tractor is stationary creates the whine or if it requires forward motion. I guess there is the possibility the whine is not heard in 4th or reverse simply because the engine rpm's were low. You might try this test at pto rpm with the clutch disengaged and again with the clutch engaged the range selector in neutral. If the whine isn't heard when the clutch is disengaged but is heard when the clutch is engaged and the range is in neutral, then the whine may be TX gear noise.
Hope this helps some. There are some other testing ideas to help identify the location of noises, but I'll keep this note reasonable short.

I forgot. This testing stuff should be done with the tractor in 2wd. Many front axles are driven from a differential ring gear, and the 4wd could possibly be a source of noise. ....

I would go to a dealer's lot and drive another one. You left so many holes here it is tough to figure out which way to tell you to go with it other than back to the dealer. It is a new tractor and it doesn't sound right. ....

OK, the dealer says this is "normal" transmission noise, common to these models. I have two years of warrenty left so I am not going to sweat it. Thanks for all the replys. ....
