Spreader Calibration fiasco

[Retro67]

Here's the scoop. I calibrated my spreader this AM. I used &quot;medium&quot; sized particles to calibrate with (plain old polyon coated NPK.) <p>So I then adjust the spreader for &quot;fine&quot; particles since that is what I was spreading this afternoon. I followed the recommendations of the manual for my Prizelawn Bigfoot spreader. I got 1/3 of the way through and was nearly out of material that should have been spread over the whole area. <p>What is the problem here? Has anyone else run into this? I am thinking of purchasing a Lesko and wonder if it will be much less hassle free?<p>John
