I would have never known mine had a problem if the wife hadn’t missed a small area behind the house. She gets ambitious and does it a few times each year. The nice weather days we were at the show she did it. I only ran it a few minutes to cut that small area and heard spindle bearing screaming. Otherwise would have found it when the grass was all overgrown and probably had to push mow while I waited for parts. Would not have been a good day. Glad it happened the way it did.
