In this step by step tutorial I will give you a full walkthrough of how to level the cutting deck on my 36” Scag V Ride 2. Links to materials: Deck Leveling Gauge a.co/d/dFThw6z
Loosening the adjustment bolt lowers the corresponding corner down. But it’s best to do 2 at a time. Do your sides first (2 RH bolts and 2 LH bolts) then work on your fronts and backs together. Need as flat a surface to work on as possible because if it’s unlevel then loosening the bolt might not lower it down as gravity will do whatever it wants.
