I'm cutting at 2 1/2 front of my blade and 2 3/4 back of the blade. The deck is 2 inches off the ground I want to leave better stripes and cut around 3 inches. Would I raise the blades inside the deck or just raise the whole deck. Is it better for stripes for the blades to be higher up inside the deck or the opposite. Also what's the ideal height to cut in md. It's is my first year I have around 15 houses a week. Also the mower is a 36 inch snapper pro with mulching blades.
