Hi,I was wondering if anyone could give me an approximate setting for spreading uncoated kbg using an a.m. leonard or prizelawn spreader where the settings are designated with letters.I will be seeding a new lawn @3lb. per 1000 sq/ft.The closest i have come to a setting by cross reference is "J".Although i have not calibrated this seems to have a too large of an opening on the gate.I am thinking that someone out there has used one of these spreaders and could help me zero in on the proper setting.Thank You.
