I am looking at a brand new super z 60" deck for this up comming spring. The two motors I was looking at were the Kawi 31hp and the kohler 30hp. Just wanting to hear some thoughts on both motors. I have had good luck with kawi in the past, but I have no experience with kohler. They want a little bit more for the kohler is it that much better of a motor? Any and all comments and concerend greatly apperciated!
