Currently I run 2 Super Z, both 27hp Kohler, 1 x 52" deck and the other 60". Because we cut a lot lower than in the USA (hole 2 or 3 on the adjustment arm) has anybody found a way to stop the deck cutting great groves in the turf when it goes over a mound? I was thinking of adding 2 depth wheels inside the deck like a lot of mowers have. according to dealer here Hustler is not aware of any problem in that area. Any help would be appreciated. Also does the double blades help in cutting long grass? I was hoping the extra suction from the extra blade would lift more grass up so the blades can cut it.
