I have still been having problems with my 60" Flatlander leaving strips of grass un cut. I tried to adjust the deck but As soon as I get the front blade tips set at 3" on the second notch on the foot pedel. I will go to set the back tips a 1/4 hight but they will be way off side to side. So when level them out it throws the front off again. Is there any way that the deck could be bent or warped. It just seems there is something out of balance. I am taking it to the dealer in the morning, but I am affraid they know less about the machine than I do. Has any one else had problems with there chopper not cutting good. It only has 120 hours on it new blades did not help either.
