Before Hydraulics: The Brutal Reality of 1930s Motor Graders!

Motor grader operators in the 1920s and 1930s built every road we drive on today. They did it on machines with no cabs, no hydraulics, and no rollover protection, cranking cast-iron hand wheels against thousands of pounds of resistance, hundreds of times per shift. Construction death rates ran 150 to 200 per 100,000 workers. Ten times the modern rate.

From the first horse-drawn Adams Leaning Wheel Grader in 1885 to the revolutionary Caterpillar Auto Patrol in 1931, this documentary covers the machines, the men, and the brutal working conditions that built America's road network before hydraulics existed.
