Hi I'm new here. Just started out this year with a exmark metro 36 inch deck model num. m3615ke. Most of my customers like the 3 inch cutting height. What is best setting to obtain this I have the chart in the manual. I also run gator blades. I want to get the best stripe possible. The setting I use now is axle poss.D, 2 blade spaces below the spindle and 3 spacers below caster. Is this my best set up.
