Kubota HST Whine - L2501 Hydrostatic Drive Noise

I bought a new Kubota L2501 HST and have put 80 hours on it. The HST hydro whine is mentioned often online but rarely addressed with video. The L2501 has three 'speeds' Low, medium, and high. The whine is significanly less in lower speeds and at higher RPMs.
I will say from personal experience that after a few hours in the seat, the whine does become overwhelming (with ear protection). I notice it especially when mowing and I mow in a M or H to cover ground. Doing other tasks in L at 2k RPM, it is not as bad.
You be the judge. If you enjoy the video, please hit like and if you have interest in seeing my grapple, bucket, landscape rake, stump bucket, box blade, or rotary cutter in action, please subscribe for future videos.

To make a long story short: Two ways to hear Whine, One is to get a tractor with HST or get married.😂🤣😂

I juat got a used 2017 B2650 and i have the same concern. Its my first tractor so I'm not sure if this is normal either

My L2501 is the same I think it’s just the way these tractors are

Just bought a massey ferguson 1825e hydrostatic and it does the same thing. I almost wish I'd of saved the extra cash and just went with the shuttle shift.

Sounds exactly like when the brake is partly applied. I don't know if Kubota has adjustment on the park brake.

Do a few oil changes and the whine will get less. They are really bad when new.

I have a 2018 B3350 and it does the same thing.
