Mystery Bushing - Identification Help

[fredzink]

I found this bushing on the road along my field. Can anyone identify what this may have come from?

I’ve driven that path with a Kubota L6060 tractor, Kubota ZD331 Zero turn, and hauled an Allie Chalmers All Crop 72 combine recently. None of them appear to be missing pieces.

Looks like the inner sleeve of a bonded rubber isolation element. Typical automotive suspension stuff. The "teeth" are to prevent movement, the wear shows that didn't work ;-)

Looks like it came out of a shock absorber. Those are a core to a rubber bushing typically on the lower end of the shock mount.

Ops. Cal beat me to it.
