I am considering the purchase of a Hustler Fastrack 20HP/52" cut for use at my home, 1.5Acres. I am also looking at a Cub Cadet M48 Tank, 19HP. I have seen varying estimates on the blade speed for the Fastrack, what is it really? Is it underrated due to the target market? How does it compare with the Shortcut 1500? (The reason I ask is that I have seen that machine in action on my property, and I was impressed). What advantage/disadvantage do the smaller tires have? Does this effect the ride/handling? How is the transmission rated in comparison to a MiniZ or Z? How long can I expect it to last? Why are there no rollers on the rear of the deck? How deep is the deck? How can I expect this machine to cut on tall, thick fescue turf? How can I arrange a demo? I think I really need to see this machine cut my lawn before I buy..it would convince me to not spend the extra money on a full commercial mower. Not many dealers closeby in this area (S. NJ), but I have seen a Fastrack in person, and I feel that it is head and shoulders above the Toro TimecutterZ, and is really pushing to be a nearly commercial machine.
