I am going to purchase a Cub Cadet RTZ 50. Home Depot sells one with a Kawasaki engine and Tractor Supply sells on with a Kohler engine. I have not been able to find any engine comparisons online. I would appreciate anyones input.
ILEngine makes a great point. You could look around your area to see if any of the other dealers have units using a Kawasaki engine. If they do they would have access to parts. I know that Toro uses Kaws in their Zturns. If you can find someone who can get you parts, I vote Kawasaki, but I would rather see you go to a dealer and not the big box stores. It would be to your advantage in the future.
