i just bought a 2008 Toro ZTR 52" 7 Gauge Deck 21hp Kawi. when i go to cut grass it leave about a 3" wide by a foot long strip of pushed over somewhat cut grass. i had to double cut a yard today and i was not happy. i tried to take the blades off cause they were a little dull, but the dealer must have put them on there so tight, that i could get them off with my compressor or my electric impact wrench. i am very unhappy with the mowers cut. there is little to no build up under the deck, so that has nothing to do with it. Does anyone know what to do, or can help me do something?? im very tempted to take it back to the dealer and make them fix it. i didnt spend $6700 for a $hitty cut!!!
