I'm not a pro lawn guy at all but I mow about 8-9 acres at my place. I own a emergency vehicle equipment company, Signal 10 Upfitters LLC. I just use this site to gather info from you pros because I value expierence. I just recently purchased a new 2013 Hustler Super Z w/ 72" deck because the old mowers weren't cutting it efficient enough. Thanks for your time and all your knowledge on this great site.
