I got them to throw in a Never Spill Spout with the purchase price of my 1684 auger so now I am thinking about how to make best use of it. My idea is to somehow fasten cables with balls hanging down at different distances from the spout. Most of our small 19 foot diameter bins are about the same height so the auger will be at roughly the same angle. When the ball at 9.5 feet from the spout touches the bin eve I will know this is the perfect height to set the auger at for this bin. After the alarm goes off and the auger empties the grain should be within 2 inches of full and I can go to the next bin. The 21 foot diameter bins will use a ball that is 10.5 feet from the spout and the 36 foot diameter bins will have a ball hanging down at 18 feet. We only grow wheat and canola so I might need to use a black ball for canola and yellow for wheat. Anybody got any suggestions?
