Raymond M. Hahn, a pioneer in the development of mechanical logging systems, died recently at the age of 84. He was the founder of Hahn Machinery Inc.
Ray was a well known Lake States logging contractor in the 1950s-70s. He became even more well known when he patented the first mechanical tree processor in 1968. Ray granted a license to CanCar in Thunder Bay, Ontario to manufacture and sell his invention under the name CanCar Processor.
When the license expired, Ray formed Hahn Machinery Inc. in Two Harbors, Minnesota. He began manufacturing the machines under the Hahn Harvester brand name in 1972.
Over the next 18 years, Ray was granted a second patent and introduced three new models of his Hahn Harvester as well as the Hahn mobile Slasher/Merchandizer.
Over the years, Ray’s machines were used by loggers throughout the U.S. and Canada as well as France, Scotland, New Zealand, and Russia. His original designs were cited in patent applications by emerging forestry equipment manufacturers worldwide.
Ray continued to be active in the business until his retirement in 1990, when he and his wife sold their interest in Hahn Machinery to their children.
