Am a recent new owner of a Hustler Z and think this might be the best money I've ever spent!! Was wondreing if the suspensions eat used on the super Z can be bolted on to a regular Z and what I might have to spend to buy one. This mower is great and I can't say anything negative about it at all. I'm a home owner who has found that mowing the yard can actualy be fun! One more question...Are Gatror blades available for the 60" Z and if so what Part number should I specify. Love this website and all the info and knowledge I've gained from it!! Thanks to all!!
