I agree with the other comment. The 6way blade is terrific. But it's only available on the 40 model. I had the 40 for about 2 years then I went to the kx057-4. That was a significant change in size.. Much more room in the cab more conformable. But I wish the 6 way blade was available on the 57 as well as the 80..When you get into the 40 and above your going to have the power for the 6 way blade to be very effective.
