My friend just demoed a Husquvarna 23 HP Kawasaki Z today and says it's extremely fast and cuts very good. Do any of you have one and if so, what's your opinion of them and would you buy another? How do they compare to Exmark, Toro, DC. It looks like a well built and well laid out machine to me. How about the 23 Kaw or the 25 Kaw engine?
