I love this machine have the zt xl 60 with the kawi engine. My yard is a acre and I can blow through it in about 40-45 mins and looks great when I am finished. Went from a zero turn cub cadet to this and I will run nothing but gravely from now on. I grew up with simplicity mowers and cub cadets and this mower blows both of those away no comparison. My yard looks good enough I am now mowing 4 of my neighbors yards a week just for the fun of running my machine and the lil extra money I get for my time is just a kicker. Cut quality, comfort and ease of use make these machines top of the game.
