Belly mower. I can not determine the size of the Nut. The nut came off the bolt while I was mowing. what is the size of the nut that goes back on the bolt?
/ Size of mounting bolt and nut for Kubota B7100 HST belly mower
If you can take the bolt to a hardware store or a place like tractor supply you could just match up a nut that fits it. I think most if not all the bolts on Kubota tractors are metric.
