I was getting my riding mower ready for another season, changed the oil, filter, and I tilted the mower on it’s side to change the blades, just as I do year after year (my tractor is about 12 years old!) so once I was done and I got the mower back I found this piece laying on the ground. I have carefully examined the deck and I can’t seem to find where this would go. I tried checking the manual and a couple websites to see if I could identify the piece and no luck, anyone know where this goes? Thank you in advance!
