I live in the central FL area. When looking at the the Ferris and Everride 60" ZTR's I noticed that those manufactures decided to put cooling fans directly over the hydro pumps verses running an external fluid radiator/cooler with a cooling fan such as on the Hustler Super Z. Why in my area would the Hustler setup/system be superior to the others mentioned? Also, come mid July thru Sept just about everyone complains about the reduced quality of cut since the St. Augustine grass grow faster than we can cut it. In order to try to maintain that cut quality we are forced to slow down in the middle of our summer heat and humidity. I just hate that!! What would the new XR-7 deck do for me in this situation? Anyone care to comment??
