I received my new JRCO spreader this week. I am overall very impressed, but I can't seem to get it to spread an even pattern. I have rotated the adjustment fully counterclockwise. The pattern width seems about the same on both sides of the spreader, but it is about 30-50% higher on the right hand side. I am operating at a motor setting of 2.5. Has anyone had similar problems? Does an increased motor speed give a more even pattern? It looked like that might be the case, but it is hard to tell without putting down a tarp and doing a test.
