I do 21 acres a day with the perma green. Guaranteed. Call our local lesco and ask them how I pull from the stockpile. I pull in with a stake body dump, put two skids of 24-5-11 in the bed, have a caddy with the spreader on the back and off I go. I have 8 big sites that take four stops. In four days I have cover about 82.4 acres with that machine. Guess you'd better rethink your theory.
