Mystery part??

[Mowbizz]

Not sure if this came off of my BX25D as I found it nearby...anyone recognize it as an integral (or otherwise) Kubota part?
That is a standard "post it" note for size comparison...

Did you have your ROPS folded down? That second shot on the yellow paper looks like it came off the part where the screw knob goes through that holds the top portion tight. I think I had mine come off once.

Aha! I did have the rops folded and...I actually, found the plastic knob for the rops on the ground the day before I noticed this part on the ground!

Mystery solved!

Much appreciated!
