Been doing some severe shopping. OK I'll be honest....been salivating for the last few years for a zero turn. I cut 4-5 acres on my place and have done so for the last few years on my craftsman 42" lawn mower. she has been getting to the point to where every year I am fixing something on it to be able to cut. I am ready for a new mower I have narrowed it down to the JD EZtrak 645 or the Hustler Fast Trak Super Duty. the JD seems more heavy duty to me with the Seperate Kanzai pump/motors vs. the Hustler SD with the Z3100's but the Hustler has the Comm. Kawi and the JD has a Vanguard, Both have a 4 yr. Warranty. The hustler is gonna cost me about me about 600 more. Any owner testimonial would be greatly apreciated.
