"We’ve been with GSI since the 1950s"Clint McLeod - BriMac Farms
For the past 20 years, we’ve dried all our corn on farm. We have one of the original TopDry systems. When we are running at our best, we are drying and moving corn quickly. About five years ago we added a loading bin so we could fill a semi in three minutes. It used to take 30 minutes when we used an auger. When we break it down, we can get an extra round a day or so. We are looking to be as efficient as possible, especially knowing our farm is set to continue expanding.Watch Video
