First, which did you like best?<p>I own a Y/K ZTMax with a 61" deck, 25hp. I haven't had any real problems with it. It cuts most everything I want it to and does a good job. It is quite similar to the Exmark and has some parts interchangablity with the Lazer which gives you another outlet for parts if needed. I paid $7100 for it and $6800 for the 52 seems reasonable. The tires aren't that great and if you decide to purchase the Y/K let me know, I found a place to get a good deal on turf tires.<p>I prefer the controls on the Y/K. Check the warranties as well. Mine has a 2 year full warranty, I don't know about the Great Dane. You are also getting a 6 hp advantage on the Y/K, which may or may not be overkill. <p>Last thing, try both on your properties if possible. If they are at different dealers, judge which one offers better service.<br>
