I can only comment on the thick northern grasses we have, My buddy had a 60 inch Toro z-master with the turbo force deck and it was a complete pile of crap as far as decks go. It never left a good cut, It always clumped, never spread the grass out good enough. It cut worse then my Triton deck did before i modified it. IMO its old technology and needs a revamp.GoldPro, you have obviously been around the block on this site. Can you be a little more discriptive on how you know from your own experience. And what year models are you talking about for the Exmark and Toro? What didnt you like about the Toro deck?
