CatD8by theDecadesIn the 1920s, nobody suspected that a mergermade of necessity would result in a modern-dayindustry heavyweightSTORY BY KEITH HADDOCKn 1925, no one predicted that“Caterpillar,” the name of anew company created froma merger would become synonymous withheavy equipment. Today, Caterpillar Inc. manufacturesa vast range of construction, mining,logging and farm equipment, from the smallestmini excavator to the largest trucks onearth. <strong>Finning</strong> (<strong>Canada</strong>) is the proud dealerfor Caterpillar equipment in Western <strong>Canada</strong>.Here’s how Cat has developed the productlines that <strong>Finning</strong> sells and <strong>service</strong>s.Crawler tractor pioneers: the 1920sThe two leading crawler tractor manufacturersin the United States merged to form the futureindustrial giant Caterpillar Tractor Company.Arch rivals for years, the two companies, HoltManufacturing Company and C.L. Best TractorCompany, had developed and marketedsimilar products.Benjamin Holt had introduced his firsttraction engine in 1890 and pioneered theworld’s first commercially successful crawlertractor, later in 1904. In 1910, he registered“Caterpillar” as a Holt Company trademark.The same year, one-time Holt presidentC.L. Best started the C.L. Best Traction Company,building wheel and crawler tractors.The merger of the Holt and C.L. Best companiesin 1925 was born of necessity. Wartimetractor orders dried up and the post-wartractor market was flooded with thousands ofnearly new, cheap, government surplus machines.Holt and Best were facing huge debt,cancelled orders and possible failure; mergerwas the only solution.Immediately following the merger, thenew Caterpillar Tractor Company, based atPeoria, Illinois, streamlined its operationsand marketing network. Management chosefive tractor models to form Caterpillar’s firstproduct line: the Holt 2-Ton, the Holt 5-Ton,the Holt 10-Ton, the Best 30 and the Best 60.Forward-thinking management also beganto look for other products to expand sales.In 1928, it purchased the established RussellGrader Manufacturing Company of Min-neapolis, Minnesota. With this acquisition,Caterpillar had taken its first step toward becominga diversified construction equipmentcompany.1930s: Diesel SixtyThe diesel decade: the 1930sCaterpillar played a major role in developingthe diesel engine for use in mobile equipment.It introduced its first diesel tractor in1931, and 10 years later tractor sales werealmost exclusively diesel. From its genesis in1923, years of testing and redesigning tookplace before Caterpillar was satisfied thata field application would succeed.

1940s: DW-10 wheel tractorequipment, diesel had to contendwith variable loads, vibrations,weather, and some occasionalabuse from unskilled operators.But diesel was so popular thatCaterpillar allocated nearly all itsresearch budget in that direction.In fact, Cat’s diesel tractor wasjust what agricultural customersneeded. They liked its superiorfuel economy and the fact that dieselfuel was cheap. But the diesel engine’s chiefadvantages were its greater low speed luggingcapability, and the fact that maximumpower was available over a much widerworking range than a gas tractor.Caterpillar’s first diesel tractor was theDiesel Sixty with a 4-cylinder D9900 enginedeveloping 63-drawbar horsepower. Buildersfit it with a gasoline pony motor to aid starting.During the 1930s, the company introduceddiesel versions of existing gas models,the Thirty-Five, Forty, Fifty, Sixty, Sixty-five,Seventy and Seventy-Five. By decade’s end,Cat established the familiar D-series tractors.Wartime and scrapers: the 1940sIn 1940, Caterpillar launched an upgraded D7tractor with design refinements. Designatedthe 7M-series, it carried the Caterpillar D8800engine of 80-drawbar horsepower. The followingyear, Cat upgraded the D8’s D13000engine to 113-drawbar horsepower, calling itthe 8R-series. The D13000 engine was a winner.Installed in Caterpillar’s largest tractorssince 1935, it carried Caterpillar through thewar years and enabled the company to supplytrouble-free engines in thousands of tractorsat short notice. The slow-revving D13000 wasas reliable as an engine could be; many stilloperate today.These were the tractors that spearheadedallied Second World War efforts. Equippedwith a bulldozer blade or scraper, the tractorwas key for front-line fighting forces. TheU.S. government needed most of the tractorsCat could produce, and by 1945 more than31,000 had been shipped, many overseas.Often first on the scene, they cleared theway for fighting forces to follow. They built“The four machines thatwon the war in the Pacificwere the submarine,radar, the airplane andthe bulldozer.”bases across the South Pacific, along the AleutianIslands toward Russia and pushed theAlaska Highway through 1,400 miles of wilderness.American naval admiral, William F.Halsey, said, “The four machines that won thewar in the Pacific were the submarine, radar,the airplane and the bulldozer.”In 1940, Caterpillar introduced its firstwheel tractor, the 90-horsepower DW-10,designed to haul a scraper. After the war Catlaunched a line of pull-type scrapers to haulbehind its crawler and wheel tractors.The earth moves: the 1950sThis decade was marked by global constructionprojects, including construction ofthe U.S. Interstate Highway and the BritishMotorway systems, requiring unprecedentedamounts of earth to be moved. New Catand <strong>Finning</strong> customers were pushing industrialand housing projects forward, makingup for lost time during the war years.Caterpillar responded by updating everyone of its models with the latest technology.But the two groundbreaking events of thedecade were Caterpillar’s introduction of itsbiggest tractor yet, the D9, and the establishmentof a line of motor scrapers – high-speedearthmoving machines.The powerful D9 showed how to reallypush dirt. Ripping technology moved a stepcloser to eliminating blasting when a singleshankripper was attached to the D9. In 1951,the small DW-10 motor scraper was joinedby the 2-wheel tractor DW-21 and 4-wheeltractor DW-20 scrapers, carrying 20 and 23heaped cubic yards respectively. And theysped along, hauling at 20 mp/h.At the start of the decade, Caterpillarpurchased the Trackson Corporation alongwith its lines of crawler loaders and pipe layers.Initially based on standard tractors, themachines were redesigned by Caterpillar tobecome single-purpose machines.www.finning.ca Spring 2008 • tracks & treads 47
