Random bolt identification

[jcpawlak]

I noticed this bolt on the ground where I generally park my B2650 during the winter. I've done a cursory glance for an obvious missing bolt and not found anything, but figured I would ask if anyone happens to recognize where it originated from before I start looking more closely. It is exactly 1" long (including head), and appears to be 3/8" across the flats, with a 1/4" shank diameter (may be slightly off if in reality is metric). It looks super clean, so from an area that doesn't get much dirt/grime.

I am thinking it is from the tractor itself, but could be from the front-mount snowblower that was attached all winter as well.

Any thoughts? Thanks in advance if so!

Maybe to hold the plastic shield over the front Ujoint on the front drive shaft ??

It's out of a Boeing 737 door plug and you don't want to be found in possession.

It's metric and there are quite a few places that it could go on the tractor or an implement.

Look for holes without bolts!
