I getting ready to buy a headgate for a new lease. The chute at our farm had the swinging type automatic headgate on it. Its so old I dont know what brand it is. What im looking for is the same type but I want it to swing all the way in and out like our old one does. Ive looked at a powder river and it only swings in just a little bit. Can anyone tell me which brands will swing all the way in both directions?
