Bought a brand new Next Lazer Z, and I am having trouble with it leaving the shoots of Bahia sticking up. Unless I have very fresh blades, it refuses to cut it. I normally sharpen blades every 8 hours or so, but find myself having to sharpend them twice as often with the new machine. I sent an email to eXmark over two weeks ago, with NO REPSONSE. WTH??? Spend $10,600 on a mower, and they can't even return an email? No phone call? I told my dealer the first couple of days of owning it, and he got a rep from eXmark to come down, took my machine for the day, put about 10 minutes on the hour meter, and then called me and said "Ok, it's ready". I get to my dealer's, and guess what they did to it?? They changed the blades. Wow, if only I could have thought of that. Sure it will cut fine with fresh blades, but my other 2 eXmarks cut better even with older blades......the rep said the deck is the same as my old Ultra-Cut....well it sure doesn't cut like it. My Turf Tracer and my 60"/31HP out cut this machine 2 to 1. I have to slow to a crawl to cut Bahia after a few hours on the blades......makes it almost quicker to use the 36". I have used eXmark for 20 years, and I expected MUCH MORE in the way of customer relations. I emailed them one simple question, WHAT IS YOUR RETURN POLICY. NO RESPONSE WELL OVER TWO WEEKS. UNACCEPTABLE. Anyone else having any troubles with their new "Next Lazer Z"?
