It's happened to me before, but today it stopped me early. Spreader gummed up pretty bad with weed/feed residue. Question to all of you.... What do you do in this situation? Does it affect calibration? Spinner plate became so heavy, that my gears were stripping when I pushed it hard/quick. The spreader was clean this morning. I started at 6am and was finished by 8:30am (it was starting to dry up) got 250K down. But what do you guys do when you must go the whole day? Product was Lebanon 19-0-6 Confront-3 with Dimension. Though in the past I've had similar results with various other products.
