What is a Yumbo? This was a French Company (SICAM) that IH bought controlling interest (52%) in July 1970 so they could get into the hydraulic excavator business. It consisted of two manufacturing facilities and the machine was called a Yumbo after a local town.
The plant at Genas sets on 57.5 acres with 122,000 square feet of manufacturing and assembly floor space under roof with 284 employees and the primary product is the 3980 excavator. It had an excavation assembly, welding of attachments, pipe bending, supporting machining, and prototype manufacturing. The other plant is located in the town of Chauffailies about 75 miles northeast of Yumbo.

The International Harvester Company (abbreviated first IHC and later IH) (now known as Navistar International Corporation) was a United States manufacturer of agricultural machinery, construction equipment, trucks, and household and commercial products.
In 1902, J.P. Morgan merged the McCormick Harvesting Machine Company and Deering Harvester Company, along with three smaller agricultural equipment firms, to form International Harvester.
In 1985, International Harvester sold off most of its agricultural division to Tenneco, Inc., which merged it into its subsidiary J.I. Case under the Case IH brand. Following the terms of IH's agreement with Tenneco, International Harvester renamed itself Navistar International Corporation in 1986.
