I have a new lesco spreader and was wondering how far to move the right tab in because it seemed to throw a little heavy on that side. I am applying lesco stone wall barricade 19 0 7. What patten do you guys like to use. A back and forth or a counter clockwise. I searched through the threads but did not find a definate answer. Before you ask, I am certified and have a license. Thanks for the info.
