Mechanics with over 50 years combined experience are present to diagnose and repair equipment quickly and efficiently.  Lee Keller, lead mechanic, was raised on a farm in Long Prairie, Minnesota, and from a young age was familiar with keeping equipment serviced and ready to go. At age 17, he graduated from high school  and entered into a 3 year program for Farm and Diesel Equipment education at Staples Technical College in Staples, Minnesota. Upon graduating, he entered into the U.S. Navy Seabees as a construction equipment mechanic. When he returned to Minnesota he worked several years on diesel equipment on  the Minnesota iron range. Upon moving to Detroit Lakes, Minnesota, he spent the next 13 years gaining valuable experience as he became the shop manager of a large trucking company. Since 1984 at Keller Diesel Service, Lee has and continues to enjoy assisting the area businesses, farmers and over the road truckers by keeping their equipment serviced and repaired.
