I currently own a Lesco 50lb rotary spreader, I just purchased scotts 4 step fertilizer. I was wondering if anyone had the settings on a comparison chart. I am not a landscaper by any means nor do i want to pretend to be one, But i do care for my lawn and want my lawn to look good. I usually use johnathon green and they have the lesco settings on there bag, is there an easy way without doing the math, I know all spreaders are different, but i was wondering if there is a chart. I can't find a lesco website anymore. Please help

Thanks

Steve
