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.
