The K66 Upgrade Kit is a complete DIY replacement solution for your old, weak transaxle. Breathe new life into your tractor and install a new K66 transaxle in your tractor in about an afternoon with basic hand tools.

The K66 Upgrade Kit is not a “repair kit” for your broken or failed transaxle. It is designed to upgrade your tractor to a better than new levels of performance. Your machine will be transformed from a lawn mower to a utility garden tractor that will easily handle those heavy-duty tasks that caused your old transaxle to fail.

A new replacement lawn tractor will cost you thousands (2023 average price $3515!) and still comes with the same marginal K46 transaxle that just failed! Not only that but with increasing supply chain uncertainty that assumes you can find one when you need it. By upgrading your otherwise great tractor you will have the capability to tackle the most challenging tasks and save money in the process. Win-Win!

  • New K66 transaxle
