We, Joe Keller and Marilyn (Keller) Loegering (photo), have been working together for several years gathering machines and documentation to preserve the history of the skid-steer loader invented and patented by our father, Louis Keller,  and uncle, Cyril Keller.  Both Louis and Cyril were still able to share their knowledge and experiences, much of which has been recorded in video as well as other forms of documentation. We feel very blessed that we are able to gather so much information first hand.  It has been very rewarding to be involved in the step by step process with the actual inventors and watching as they are able to be a part of the preservation.  At first they did not think anyone would want to see "those old machines".  As they see how the history is appreciated by others, they are only now realizing the impact the skid-steer has made on the world.
