I have a scag 48 inch walkbehind. I am wanting to get it set up right for striping. The deck is set in the middle of the three holes. I want to get it the height at 3 inches and the pitch on the front at 1/4 of an inch closer to ground. For any of you experienced scag users which hole do i need to put the deck in and how many spacers on the blades and front caster wheels? Any info would be greatly appreciated.
