Tell the people why you run the Kohler 28 efi as your personal mower when you can run any mower Hustler makes, for some unknown reason you shut the door on the post where you had a chance to answer the question. I have run Kawasaki's and they are more temperamental than the 28 efi I'm running now. The Kohler 28 efi cranks and runs as perfectly as any engine could on less fuel. The boy that was talking about a quiet running liquid cooled Kawasaki with 500 hrs. on it is wonderful but why in the world would I want to fool with looking after a radiator and checking fluid and antifreeze levels when the 28 efi runs better on less fuel with more power than a 25 or 29 Kawasaki. I hope I don't have to put 500 hrs. on one before Hustler makes something that I like better and I can trade for.
