We have stand and fill 400 lb feeders with the top of feeder being 60 inches from the ground . We are a new company and have field tested these feeders for nearly a year without any breakdowns or interruptions. These feeders have pin point accuracy for corn distribution. They will broadcast 1 lb of corn per 5 seconds of spin time out to a 60 foot diameter. We have pictures of raccoons, squirrels, goats, and cattle trying to access the feed without any luck. If you are interested, please give us a call at Chow Down Game Feeders 337-515-3332.
