Kubota Push Mower help

i picked up a kubota w5021 push mower a while back. It has the brake clutch. Runs great but when its running and the blade is disengaged ONLY..... the blade shakes and rattles,.... the blade is on tight and it looks like there are three springs behind the part the blade bolts in too that allows movement.
I feel like it should be quiet when the blade isnt engaged

any thoughts?

Where the blade adapter attached to the shaft, there is a keyway. Check to see if that is sheared.

In the parts diagram I'm not even seeing a keyway

I know there should be a key on the fly wheel but ur saying there should be one at the bottom where it connects to blade adapter?

Keyway was good. Needs new rod and rings. That's what was making it shake without the compression while the blades were disengaged
