Columbus Equipment Company offers an extensive inventory of late-model used equipment from a large variety of manufacturers including Komatsu. Check out our current offering of used equipment. If you have any questions or need any additional information on a specific piece of equipment, please contact Jon St. Julian at (614) 332-3528.

Komatsu ReMarketing allows you to invest in high quality used equipment without spending a fortune. Unlike used equipment brokers and dealers who sell their equipment "as is" most Komatsu used equipment is distributor certified. That means Columbus Equipment Company performs testing, diagnostics, and minor repairs before we give it our stamp of approval. We even offer financing options and maintenance programs to make buying this high-quality used equipment that much easier.
