I was mowing with my 36" Mini-Z the other day when I heard and felt a "pop" from somewhere on the mower. I got it back on the trailer to find that the rim on the right drive wheel had "cracked" almost the whole way around. The lugs were all tight and the wheel was only holding on to the hub by one small section of the rim still connected to one lugnut. My dealer (Wayne Strickland--Land & Cotes in Portsmouth, VA) had me back up and running the next day with BOTH drive rims replaced. I got great service, but I was wondering if anyone else had experienced this problem. Thanks.
