I have a 2008 46" Exmark Lazer Z HP with a Triton deck for my residential jobs. Bought it brand new. I am having troubles with it cutting. It is missing grass where the center of the blades are. I have sharpened blades, the baffle is adjusted to its highest point, and I cut varying from 3 - 4 inches. The deck is clean (no collected grass) and the blades aren't bent. I'm looking for suggestions on what could be wrong so i can avoid going back to the dealer. I've tried 2 different sets of blades. My only other guess is that, it's a 19hp kawasaki and it just doesn't have enough power to get the blades moving fast enough to keep up with the land speed of the mower. Although even when I slow it down to a crawl it still misses. HELP!? I'm a rook I've only been at this for 3 years and this is my first Exmark cuz I had an offer that I couldn't refuse. All I have owned before were Scag walk behinds so I'm completely lost right now after going through all those adjustments. HELP!
