hold", with emphasis on parts and service to keep existing machines running, but its war materiel production was pushed to the maximum of productivity and output. In the late 1930s through mid-1940s, Allis-Chalmers made machinery for naval ships, such as Liberty ship steam engines, steam turbines, generators, and electric motors; artillery tractors and tractors for other army use; electrical switches and controls; and other products. Allis-Chalmers was also one of many firms contracted to build equipment for the Manhattan Project. Its experience in mining and milling machinery made it a logical choice for uranium mining and processing equipment. Allis-Chalmers ranked 45th among United States corporations in the value of wartime military production contracts. Immediately at the war's end, in 1945–1946, Allis-Chalmers endured a crippling 11-month labor strike. Buescher was convinced that the corporation never entirely recovered from the effects of this strike. This seems debatable given the various successes that Allis-Chalmers did have during the next 30 years, including prosperity in the farm equipment business in the 1950s and 1960s. But it certainly gave competitors a chance to grab market share. After WWII some companies refused to sell equipment to Japanese farmers. Allis-Chalmers dealers did not hesitate to sell to these farmers so many farms to this day still have an Allis-Chalmers tractor in Oregon. In 1948, the Model WC was improved with various new features and became the Model WD, another top seller. The WD was a milestone for the company. It included fully independent power take off, which was powered by a two clutch system. It also included power adjust rear wheels, which became an industry standard. Production of this model continued into 1953, with nearly 150,000 tractors produced. 1950s The 1950s were a time of great demand for more power in farm tractors, as well as greater capability from their hydraulic and electrical systems. It was also a decade of extensive dieselization, from railroad locomotives to farm tractors and construction equipment. In 1953, Allis-Chalmers acquired the Buda Engine Company of Harvey, Illinois. Allis wanted Buda for its line of diesel engines, because its previous supplier, Detroit Diesel, was a division of General Motors, whose recent acquisition of the Euclid heavy equipment company now made it a competitor of Allis-Chalmers for construction equipment business. The Buda-Lanova models were re-christened the "Allis-Chalmers Diesel" engine line. Diesel engineers were busy during the following years updating and expanding the line. In
