Located in East Grand Forks, MN, Mayo Manufacturing Co. was founded in 1952 by Mayo Delisle. The company began as a repair and light manufacturing shop until a couple of decades after its establishment, when it grew to include the lines of high-quality crop handling equipment the customers have come to know and trust.

In 2006, Harriston Industries and Mayo Manufacturing joined together as Harriston-Mayo to provide agricultural industries with a wide variety of the finest planting, growing, storage and loading equipment. Their line of products supplies growers with unmatched precision and gentle, yet high-capacity handling for a superior end result.
