I'm fairly new to the ZTR game and have been doing some research on a few mowers. I had a Husqvarna ZTR with a stamped deck and that puppy cracked after 2 years. So, now I'm looking to step it up to a more commercial style mower. I'm looking at the Hustler Fastrak, Hustler Fastrak SD, Kubota Z125S, eXmark Pioneer S-Series, Bad Boy CZT Elite, Gravely Pro-Turn, Husqvarna M-ZT, and Ferris IS 700Z. I realize that is a big list, but I just started the search this week. In my head I'm seriously considering Hustler, eXmark, or the Ferris (mainly this one), but I'm open to opinions on all of these. I have a Hustler, eXmark, and Gravely dealer within 20 minutes of me. The closest Ferris dealer is an hour away. I'm looking at a 52"-54" deck and wanting to keep it at $6000 or less. Obviously less if I can help it. Are the larger tires really that big of an improvement? Does the suspension help on the Ferris to compensate for the smaller tires compared to the others? Do I really need a Kawasaki engine or will the Briggs and Stratton on the Ferris be good enough for me considering it will be doing 5 acres or less a week.
