Leonard’s Diesel Repair started doing business in 1980 and was founded By Leonard Zugzda. In the early 80’s we were primarily overhauling diesel engines in over the road trucks, specializing in Caterpillar and Cummins engines. That business developed into general repairs / service, on heavy and medium duty trucks for local fleets as well as long distance trucking companies. Soon thereafter, we were doing general repairs on local delivery trucks and private tour buses.


Sam Zugzda, who worked in the shop while growing up, left in the early 90’s to work in the underground construction industry. Starting out as a mechanic and then progressing  into the field as a truck driver, equipment operator, and eventually supervising projects.

In 2001, Sam left the construction company to take over as President of Leonard’s Diesel Repair Inc. The company soon thereafter began to focus on construction accounts and local fleet work. Currently we are a warranty center for Kubota Engine America and Kohler Company. We have developed a good working relationship with Kubota, Kohler, and a variety of small and large equipment OEM’s over the years.


Parts Barn was started in 2013 to help customers locate parts which they were having difficulty finding locally. We had a surplus of takeoff parts from engine conversions which were being done at that time. After advertising our takeoff parts we started getting calls from across the US and Canada from people needing parts to complete their projects or keep their equipment running. 

We work directly with Leonard’s Diesel Repair Inc. which is a factory authorized service and warranty center for Kohler Engines, Kubota Engines America, and a variety of other OEMs. 


We also have a good working relationship with several other manufacturers. Below is a partial list of manufacturers who we are authorized to sell parts for.
