Well said Stan. I think I'm ok with the deck. Although I did notice a small scalp when stopping too fast. I know how to level the deck if needed. I'm going to pass this on to the dealer. There aren't many Gravely dealers in my area of So Florida. (only 1 that I know of) Without your advice I might of bought a new seat and had the same problem. So, yes 2 psi made a huge difference.
