This K66 Upgrade Kit is a complete replacement for broken/failed transaxles, it will also bring your tractor up to a level of performance greater than it ever was.
It will have virtually TWICE the torque to the rear wheels. In addition, you will have a fully serviceable transaxle built to automotive standards.

Instead of an otherwise perfectly good tractor with a marginal transaxle, you will now have a real Garden Tractor that will perform as you expected when you bought it.
It will easily handle the heavy-duty jobs that caused your old transaxle to fail.

This kit provides everything you need to complete the upgrade. Nothing else to buy. You simply install the kit and transfer your current tires over to the new rims.
