I'm looking to add a mower for maintaining our mid-size residentials. The Quick36 works great on the smaller 5K properties. The 60" SuperZ is perfect for the half-acre plus sites. But when it comes to those in-between, I feel I can do better. A walk-behind is out. A 60" deck is too wide to give me a smooth enough cut in the tall-fescue. My Hustler dealer also carries Walkers. All I've heard about these units is what a super quality of cut they give. But I've also heard they are fairly slow compared to most ztr's. I'm considering a 44" or 52" Mini SuperZ but am open to other ideas. Walker guys. Will I be frustrated with the speed of these machines? Face it folks, time is money. I don't have the time to piddle around on a $11,000 mower. I want an excellent cut but I gotta' go. I guess I want my cake and eat it too, huh.
