😱 How R. G. LeTourneau Changed History With His Big Machines 😱 

The story of R.G. LeTourneau is nothing short of extraordinary—a tale of innovation, faith, and relentless determination that forever transformed the world of heavy machinery and construction.

Unlike many of his contemporaries, Robert Gilmour LeTourneau was not a man molded by formal education or conventional business practices.

In fact, he was a sixth-grade dropout with limited schooling, yet he went on to found a company that pioneered modern earth-moving equipment and invented the revolutionary electric wheel.

How did a man with such humble beginnings come to change history with his big machines?

LeTourneau’s journey began in 1901, when, at the age of 14, he left school to work in an iron foundry.

His early years were marked by a hands-on approach to learning and an insatiable curiosity about machinery.

By 21, he had taken a few correspondence courses and humorously awarded himself a “Bachelor of Motorcycles,” aiming to become an auto mechanic.

This self-driven education led him to a job at a garage in Stockton, California, and by 23, he co-owned the Superior Garage.

His passion for mechanics was evident, but it was an accident at the San Joaquin County Fair in 1912—where he broke his neck in a car he had modified—that physically marked him for life, leaving his neck tilted to the right.

Returning from service in the Navy during World War I, LeTourneau faced a major setback.

A car dealership in which he held a 50% stake was drowning in debt, largely due to his partner’s alcoholism.

Forced to extricate himself from this failing venture, LeTourneau was left $5,000 in debt—a significant sum at the time.

To repay his debts, he took a job repairing a farmer’s broken tractor.

Skeptical at first, the farmer tested LeTourneau’s repair by leveling 40 acres using the tractor and a borrowed scraper, which worked flawlessly.

This success launched LeTourneau’s reputation as a skilled mechanic and problem solver, leading to further repair jobs.

As his reputation grew, LeTourneau began bidding for larger land-leveling contracts.

He was relentless, always underbidding competitors and inventing machines on the fly to speed up work and avoid financial ruin.

In an era when road construction still relied heavily on manual labor and mule-drawn plows, LeTourneau introduced mechanized earth-moving technology that was revolutionary.

His innovations were not just about machines—they were about transforming an industry stuck in the Stone Age.

In 1919, LeTourneau experienced a spiritual awakening that deeply influenced his life and business philosophy.

As a devout Christian, he sought counsel from his pastor, Reverend Devol, wrestling with the idea that true dedication to God required becoming a pastor or missionary.

However, Reverend Devol’s words changed everything: “God needs businessmen too.”

This revelation led LeTourneau to view his business as a partnership with God, a principle that guided his decisions and fueled his perseverance.

One of LeTourneau’s key innovations was redesigning the scraper—a machine used for earth moving—by adding a generator and two electric motors.

This allowed a single operator to control the tractor and the scraper blade simultaneously, vastly increasing efficiency.

He sold his earlier machines to local farmers, expanding his reach and influence in the San Joaquin Valley.

By 1926, LeTourneau had secured his first major contract: building a highway between Stockton and Oakland, California.

This project marked a turning point, demonstrating the capabilities of his machines on a large scale.

In 1929, an order from a Russian contractor prompted him to formally establish R.G. LeTourneau, Inc.

That same year, he introduced pneumatic rubber tires on his tractors, a groundbreaking innovation that improved mobility over rough terrain compared to traditional steel wheels.

Despite these advances, LeTourneau faced significant challenges.

At age 40, in 1927, a major construction job went awry, plunging him $100,000 into debt.

Yet, he remained steadfast, famously remarking, “He uses the weak to confound the mighty,” reflecting his belief in divine providence.

Even while completing the job without working on Sundays—a testament to his faith—he struggled financially.

Creditors demanded better financial oversight, leading to the hiring of an accountant, Mr. Frost, who uncovered that LeTourneau had been selling his own machinery to cover debts.

This revelation prompted a strategic pivot.

Encouraged by his attorney, LeTourneau shifted focus from contracting to manufacturing his innovative machines.

This decision proved transformative.

During the Great Depression, when many businesses faltered, LeTourneau’s manufacturing enterprise flourished.

His net profits soared from $52,055 in 1932 to over $1.4 million by 1938—a remarkable achievement in such difficult economic times.

In 1935, partnering with Caterpillar, LeTourneau built a second manufacturing plant in Peoria, Illinois.

When flooding submerged the land he purchased for the plant, he innovated again by designing a crane welded to a tractor chassis, enabling construction to proceed.

The Peoria factory quickly produced its first 13 large scrapers.

Two years later, in 1937, LeTourneau designed the Tournapull—the first self-propelled, four-wheel scraper.

LeTourneau’s expansion continued with factories opening in Toccoa, Georgia; Australia; England; Mississippi; and Longview, Texas.

The outbreak of World War II dramatically increased demand for earth-moving equipment, essential for building roads, runways, and military infrastructure.

LeTourneau’s machines played a vital role in constructing airstrips on Iwo Jima and repairing bomb craters in Normandy, earning praise from military leaders like Major General Eugene Reybold, who said, “Victory seems to favor the side with the greater ability to move dirt.”

After the war, LeTourneau turned his inventive mind to new challenges.

The growing need for paper products spurred the creation of machines for cutting and moving trees.

The expansion of highways required even larger earth-moving equipment, which the Longview plant produced, contributing to projects like the I-20 highway near Longview.

By the early 1950s, LeTourneau’s equipment was in high demand.

In 1953, he sold the earth-moving division of his company to Westinghouse Air Brake Company for $31 million.

As part of the deal, he agreed not to manufacture earth-moving equipment at certain plants for five years.

During this period, LeTourneau pioneered the electro-mechanical drive system, known as the “electric wheel,” which placed an electric motor in each wheel, allowing independent operation.

This innovation enabled the creation of larger, more versatile machines, including giant tree crushers, overland trains, log loaders, and even concrete house-casting machines.

LeTourneau’s electric wheel technology also revolutionized offshore oil drilling.

In the mid-1950s, he designed mobile offshore oil-drilling platforms with 140-foot retractable legs.

Partnering with George H. Bush, then president of Zapata Oil Company, LeTourneau developed “The Scorpion,” the first mobile oil rig.

He financed the project himself, agreeing to receive nearly $1 million and company stock if successful, or cover all expenses if it failed.

The rig’s success transformed the oil industry, and by 1970, over half the world’s drilling platforms bore the LeTourneau name.

Today, LeTourneau’s legacy endures in machines equipped with tires 13 feet tall and weighing over 15,000 pounds.

The Tournapull, initially rejected by Caterpillar, was eventually adopted industry-wide.

The company he founded in 1929, R.G. LeTourneau, Inc., was purchased by Marathon Manufacturing in 1970, becoming Marathon LeTourneau Co.

It later evolved into LeTourneau Technologies and was acquired by Joy Global in 2011, then by Komatsu in 2016.

The Longview plant remains a hub for manufacturing the world’s largest front-end loaders, used from Montana to Brazil and Australia.

R.G. LeTourneau’s story is a testament to the power of innovation, faith, and perseverance.

From a sixth-grade dropout to a titan of industry, he reshaped the construction and mining landscapes with machines that moved the earth and revolutionized oil drilling.

His belief that “God needs businessmen too” guided a life of purpose and invention that continues to impact the world today.
