That is part of the frustration with this issue. The vendor is not able to narrow the list of transmissions that may fail. If the transmission is destined to fail, it is failing extremely quickly. (Usually within the first 5 hours of use.) The failure rate (from a % standpoint) is not high enough that everyone in all parts of the country will see it. However, the failure rate is high enough that it does not meet Exmark’s standards or expectations nor those of the customers. For customers who are using them and have more than 20 hours of use, they probably do not have a transmission with issues. BUT, just to be sure, we are going to extend the warranty on the transmission portion of the units until 2 years from date of purchase. If customers have any concerns or questions about their machine, they are always welcome to contact us directly.
