"And two years ago, during our 50th anniversary, we celebrated Louis and his brother, Cyril, and everyone else who helped make Bobcat a success over the last five decades.
"The Keller brothers’ drive to help make common jobs easier for farmers and others helped launch the compact equipment industry, and their contributions to Bobcat and the state of North Dakota in particular will never be forgotten.
"Our thoughts and prayers go out to the Keller family, and we join them in honoring Louis’ legacy."
