We picked up a 44" Mini Z this year for our residential accounts. We have been forced to double cut EVERY lawn we do, because it leaves two tracks of strands sticking up. We have been religiously cleaning the deck, the blades have been sharpened every morning, we tried the stock blades, as well as gators, and even double blades, but still nothing! If we can't get this thing to cut it is going back, because it just loses time. We are thinking about bringing the 52" snapper walk behind out of retirement. John Deere dealer has recently marked down their 48" mini Z trac... might be making a visit up there. Please Help!
