I just finished a month of research and demo cuts on my lawn. Needless to say it was exhaustive and I am glad I am at the end. Thanks to my local dealers and the knowledgeable people on this site, I feel certain I have made the best decision. I purchased a 18/44 Fastrak. I chose it over even the more expensive FULLY comercial models from Scag and Exmark. For my use, which is only residential, the Fastrak won HANDS DOWN! Even if I were somewhat commercial I would have still been tempted to go with the Fastrak because of the features when compared to the other brands. The only items not commercial are the IZT hydros and the seat. MY DEALER THREW IN A PREMIUM SEAT AT NO COST! The cost to replace the hydro units, if ever needed, is far less than the cost to upgrade to a fully commercial unit. The decision was a no-brainer. I also want to commend my Hustler dealer for his help in bringing mowers to my home, installing mulch kits just so I could use them on my lawn, and putting up with my obsessive questions and scrutiny. If anyone needs a reputable, knowledgable and FAIR Huster dealer (Louisville area) email me for info. The pricing he gave me was better than any I have seen others mention on this site as well. Kudos to Hustler, PJ, and my dealer.
