I own a Snapper S200XT Zero Turn Mower. My problem, I set the blades up high, 3 1/4 inches, and the scalp wheels are then way too high off of the ground. There is no way to adjust them lower. Should I purchase larger wheels? They would be too large for the two middle wheels since they are close to the front of the deck, or is there a way to add a bracket that would allow me to move the wheels up or down as needed? I do not understand why there is not a way to adjust them. Thanks!!!
