Our Story Michael and Amy Hennes Started Hennes Machine & Repair in 1997. We started in a small farm shop East of Willmar. We eventually out grew the small shop on the farm and purchased a building in Atwater, where the company has grown into a diversified repair facility for the Trucking and Agriculture Industry. We Repair and Service all types of Trucks and Trailers including some agriculture tractors and heavy equipment. We also have a full service engine machine shop for large and small diesel engines, automotive, some small sport and experimental aircraft engines. We can work on just about anything and look forward to servicing your needs in the future. Our motto is "If it needs repair, alterations or engine work, we can most likely help you out!"
