Kelderman Manufacturing was founded in 1970 by Gary Kelderman. Known throughout the agricultural industry as a leading inovator, Gary currently holds over 25 patents on items ranging from rubber track systems for combines and tractors to corn harvesting attachments to hay raking equipment to air suspension systems.

Today, what started out in a one-stall "hot rod" shop, has grown into a 30-acre, 80,000 square foot manufacturing facility with an additional 20,000 square feet of expansion currently underway with plans for completion in 2010. The company has changed and evolved considerably over nearly 40 years and is known and respected for being very diverse in the products it offers.
