2018 Brutus (60 hours) running a snowblower (10 hours).

I am experiencing increasing rumbling coming from the front PTO shaft while running the blower esp at idle. Rumble is not happening with no attachment.

Any ideas? Is it vibration in the blower that is transferring back to the shaft?

In general I find my snowblower to be noisy. Try taking slow motion video of it with blower running and unit sitting still. Bent shafts, and out of balance or out of alignment parts seem to show up well. If sprocket and chain driven version, make sure it is lubricated.
