Brian on the Exmark page just told me that the Kohler 27 and Kawasaki 28 are going to be the same price. So given the choice which would you choose and why. The Kohler is time tested reliable engine and the Kawasaki has more power, cubic inches, and the Kaw name for dependability but this engine it's self is unproven. Exmark told me they were still putting it through the test but Kawasaki usually does their homework? To be honest I was surprised but here was his respone to my question about the price difference. "Hello, zero $ difference, the list on the Lazer Z 27/60 and Lazer Z 28/60 is $9699." I think the 31 hp Briggs list at $10,300 or so but now it has the torque and hp to get the big jobs done no doubt. But is it as reliable as the other two and would the fuel use be within reason?
