I have the AS 1,000lb electric model, stand and fill. It holds 17 bags of protein. I have an issue with feed bridging in each corner which prevents approx 150lbs from feeding out. So, I basically have an 700lb feeder.
Also, just burned the motor up because the feed backed up due to lack of activity related to the anthrax outbreak.
Is your feeder empty when you get there to fill it? Feed sitting inside a hot feeder without any way to vent the heat/moisture out will get brown bugs inside it. The bugs will cause the feed around the edges and bottom of feeder to get powdery and after a while it will bridge up around the sides due to lack of flow. Feed with to many fines/dust will do the same and bridge up around the sides. I would try to vent that feeder somehow and make sure it empties completely every 4-6 months. Venting is simple on their feeders and their lid has a lip. Take the lid off and I would take 2 self taping metal screws and screw them on the top lip of the feeder hopper. Put 2 on each side for 8 total. They will be short enough to allow the lid to still overlap to keep moisture out but allow the heat build up inside to vent out. When putting feed in the feeder on top of older feed, I would suggest putting in one bag of fresh and take a shovel and mix in the new with old feed. None of this will help much with your Anthrax problems this year but maybe in the future it will help ward off any problems.
