I just bought a Scag 36" WB fixed deck. I like to cut around 3 1/2 inches but wanted some help on the setup. I have the advantage deck and it is still factory set the middle range. The rear of the deck is at the Highest point. I have 2 spacers above the blades.(2 under spindle)(3 on top of spindle) I have 3 spacers on the front wheels.(3 under frame) (1 over frame) I just want to keep the pitch right and have a nice cut. I have read in the manual that 3 spacers above the blades(below spindle) is best for suction and discharge. What is the best way to raise or lower the deck if I get an evergrown yard? Blade spacers or front wheel spacers? Same question if I need to lower the deck. I really don't want to mess with the rear of the deck. pain in the butt if I am in a hurry. Thanks for any help with setup on my new mower.
