CLIFF'S BIG MO 400 MILITARY TRACTOR



Cliff Ingold acquired his Minneapolis-Moline Model 400 Military Tractor in 2004 from Monroe Lang, a farmer in the Harper, Texas, area. Lang indicated that it was a "Plowin' Jessie!" The tractor sat in Cliff's back yard until other projects and some health issues were resolved, but it finally worked its way to the front of the que. An interesting note is that the tractor is supposed to have five forward speeds and one in reverse, according to books being consulted; however, Cliff's tractor only has four speeds plus reverse.

Cliff's Big Mo was built in September, 1959, and it is Serial Number 17000369. The Big Mo 400 Military Tractor was based on the Big Mo 400 Tractor, which was the industrial model of the Jet Star Farm Tractor.

A BRIEF HISTORY OF THE MM BIG MO 400 MILITARY

The Minneapolis-Moline Power Implement Company was founded in on April 18, 1929, as the result of a merger between the Minneapolis Steel and Machinery Company (MS&M), the Minneapolis Threshing Machine Company (MTM), and the Moline Implement Company (MIC). MS&M had the Twin City line, which included tractors, threshers, industrial engines, structural steel, and a combine. MTM produced the Great Minneapolis Line consisting of tractors, threshers, combines, shellers, and industrial engines. MIC offered the Flying Dutchman Line of plows, harrows, cultivators, drills, and planters. There was considerable market overlap of tractors and threshers. Eventually, the Minneapolis tractor and the Twin City thresher and sheller were discontinued.

The Minneapolis-Moline Power Implement Company name was changed to the Minneapolis-Moline Company (MM) in 1949. The tractor plant was located in Hopkins, Minnesota. MM acquired the B.F. Avery and Sons Farm Equipment Company on March 1, 1951.

Motec (Moline technology) was originally a subsidiary of MM; however, the names were reversed in 1961 to make Motec Industries the parent company. Motec's three primary divisions consisted of the Farm Machinery Division, the Industrial Division, and the International Division. Each of the Divisons had a number of subdivisions.

Big Mo tractors were produced by Motec Industries between 1959 and 1964. They were industrial models of MM farm tractors. The industrial models had larger engines with heavier crankshafts and rods and their axles and wheels were reinforced to handle the loader and blade work usually associated with industrial work. All industrial models, including the military version, were painted Highway Yellow. Big Mo models included the Big Mo 400, the Big Mo 400 Military, the Big Mo 500, the Big Mo 500 Diesel,  and the Big Mo 600.

Motec Industries was purchased by the White Motor Company on January 1, 1963. The White Company had purchased the Oliver Company in 1960 and the Cockshutt Company in 1962. Some Minneapolis-Moline tractors produced by White were based on Oliver platforms. Also, some tractors sold during the early 1970's were built by Fiat in Turin, Italy, outfitted with appropriate tin and paint and rebadged as Oliver or Minneapolis-Moline tractors.

The White Company restructured several times during the 1970's in an attempt to cope with depressed economic conditions. The Minneapolis-Moline name was dropped in 1974. AGCO purchased the White Company in 1991.
