For those of you who may not know, Puppy paws and I have had a different opinion about the Super Z on another thread. This is info. for anyone with a Hustler or is thinking of buying one. Puppy showed pics of his lawn after cutting with the Super Z at 15MPH and how it did a good job. I don't refute that. He has owned Super Z's and I have not-I give credit where credit is due. However, I was the first one in 6 counties in 98' to own a Hustler 1500 and I bought a 3200Z in 01"($21,000). I have had a standing relationship with Hustler and the Southeast district sales manager for 10 yrs. I think that fact and being in this business for yrs. qualify's me to have a strong opinion about Hustler. I would like to be respected for being in the field for lots of yrs. and having an "experienced opinion." I'll do the same. Hustler advertises having the fastest machine on the market capable of 15MPH and the machine will do just that. However, when they first came out, I asked about that and I was told that the Super Z was designed to do 15 MPH as a "transport speed" and not in mowing conditions. Hence the lack of torque in different mowing conditions compared to a regular Z. They are geared tall and it doesn't take a lot of torque on asphalt. The purpose and meaning of the transport speed of 15MPH is, if you have several yards in a neighborhood, you can go from yard to yard at 15MPH without loading the mower, which saves time.Puppy paws didn't agree with this and in fact claims that he had them change the wording in the literature to exclude the word "transport speed." If you look in the 07' manual, you will still see the word "transport" in the manual. It states:Transport 0-15 and mowing 0-10. Puppy's suggestion was to call the factory and prove him right on his facts so I did just that. The lady at Excel Hustler stated that the word "Transport" means to travel from location to location which is just what I had said. I then spoke with the district sales manager and he confirmed the same thing. He stated,"we do not advertise the Super Z to mow grass at 15MPH. The 15MPH is a transport speed which is clearly speeled out by reading the manual. A super Z is capable of mowing grass at 15 MPH if it's flat and not tall but that is not the intended use. A person should not be mowing tall grass at 15MPH, that's ridiculous." Anyone on here can call Hustler and they will tell you the same thing. In fact, he plans to pass this info. to the top and Hustler "may make a statement also." This isn't about who's right or wrong, it's about the correct info. and using a machine for it's intended purpose. An F550 is capable of 19,000lbs, but it wasn't intended to do it day in and day out. That's where the blown engines and torn transmissions come into play. Manufacturer's design machines to do more than their limit from time to time, but if you push them to their limit on a daily basis, they will break. Happy mowing!!
