I purchased a 2305 with 62C mmm about a month ago and the cut quality is not good at all! I have tried running it wide open and at 2500 rpm's, slow or fast, there is no difference. I am not cutting a hay field either, in fact it is a newly planted lawn that is not very thick. The areas that are not being cut are where the blades meet or (roughly) where the tire tracks are. The discharge side is slightly worse than the other. In looking at the blades they appear to be fine?? Any idea on what to look for before I complain to the dealer?
