Dallas Henry


Dallas and Sue Henry

Dallas & his wife Sue live in Highmore, SD. He grew up on the family farm north of Highmore. With lifelong experience and a passion in agriculture under his belt, Dallas started his career in the auction business in 2000. By 2003, he began his career as a CIH salesman at Pioneer Garage, then Titan Machinery, and after some time, a John Deere salesman. After forming a cattle panels business with his son Lucas in 2018, looking for a change of pace, in 2021 Dallas, his wife, and Lucas, founded Henry Sales as an AuctionTime member. With over 20 years of machinery sales experience under his belt, Dallas is here to help you list items, take pictures, and field the questions from potential bidders.

Lucas Henry

Lucas has run farm and construction equipment his entire life. Like his father before him, he has a passion for farming and the land. He has a diesel and precision ag degree from LATI in Watertown. When he's not reconditioning equipment for a local machinery dealer, or volunteering as a firefighter and ambulance drive, he can be found helping his folks at Henry Sales.
