L2502 PTO noise

[Orange man]

My new L2502 PTO makes a strange noise at times, it makes no noise without a load on it but when using the finish mower it will make a whirling, rubbing sound. Works fine and does not slip, Just wondering if anyone with a L02 series tractor has noticed it. Thanks

Let me guess, L2502DT
And it does it when you change engine speeds too.

Most likely over running clutch:

No, I should have said it is a HST

Well then take a video/audio of it doing it and post it on youtube and give us a link to see/hear what it's doing.

Got the same issue with my new 2502 (HST) sans rubbing sounds. Figured it's internal hydraulics when the brush hog is under load. It is loud enough to require hearing protection.

Does it do it ALL the time or just with a load on the PTO?

If there is a mower on the PTO, does it make the noise when the mower is spinning without any mowing going on or only under a mowing situation, or in both cases?

Mine can make the noise without mowing, just stopped, but I can be mowing and it makes no noise, Mine only has 7 hours on it so maybe just needs to break in.
