The roll over protection system (ROPS) retention bolts may not have been tightened during the final assembly process. Under some operating conditions, the ROPS retention bolts can become loose, putting the operator at risk of injury.
What to do...
Update (January 14 2019): The recall is now complete and all units repaired.
To avoid personal injury, customers should stop using the affected mowers until the mower has been inspected and ROPS retention bolts torqued by your local Kubota dealer at no charge.
