I’ll check my deck is set correctly. I just remembered that correct tire psi is also helpful. I think is 10-12 psi.Well well! The dealer I bought from said it was the high speed of the blades. Hmmmmm! I will look at cutting the discharge deck opening. Thanks on the reply.
I have read about all there is about the issue. I did get some better results by making sure the pitch of the deck was indeed a 1/4 taller in the rear than the front. And that side to side is plumb level.
