I just picked up my new Lazer Z this afternoon. I'm pretty excited about it. I ran over a friend's yard but it really didn't need cutting. I got the 48" Next Lazer Z with the 23 HP Kohler. My older 52" has the same engine and cuts great. The Next Lazer seems to be great. The pump response is awesome. Very smooth. Also very fast mower. I watched a video of a local guy on a huge steep hillside on one. They stick great.
