What is this part? 2014 Grizzly 350

I have a 2014 grizzly 350 with around 40-50 hours on it. I rolled it out of the garage the other day and found some type of stainless lock washer, I cant post pictures due to being a new member, so I know this is not very helpful, but I didnt know if there was something common that it might be. Any help appreciated. Thanks
