Dear Hustler, I am putting together a report for my banker. I would like to know what the expected life span is for a well kept machine. I know there are tons of factors, but I would at least like an educated guess from Hustler and other readers. Conditions are below. 2007 Hustler 60" XR7 27 Kawi LC Runs 4-5 hours per day cutting normal Bermuda, Centipede, Etc.. in North Florida. Machine will be maintained under Hustler Specs and Recommendation's. Please give me an idea as how to figure the life span for replacement. 1,500, 2,000, 3,000, 4,000 Hours ??? I need some help here. Thanks, T.D.
