Found Kubota Bolt

[jjeff]

That is a JIS bolt, so it did come off of something japanese. My Cat with a Mitsubishi engine has a lot of that grade 7 bolts.

Here is a quick equilivencey formula...

SAE Grade 5 = metric 8.8 = JIS 7
SAE grade 8 = Metric 10.9 = JIS 10

Thanks learned something new.

seat belt bolt?

It's so clean and new looking, it may not have come from the tractor, especially with the washer still intact on it.

Tractor is still fairly new.

Fabricator/installer at factory/dealer dropped it during work in an inaccessible location and just grabbed another one. Too new/shine to actually be in use.

Check everything that looks like it'd be dealer installed. Ive taken delivery of 4 new kubotas over the years at work and my local dealer is notorious for not tightening bolts.
