They Built the Biggest Wheel Loader on Earth. Then It Vanished.

In 1973, Clark built the biggest wheel loader on Earth. Caterpillar needed 16 years to match it. Only 14 were ever made, and then it vanished. This is the strange story of the Clark Michigan 675.

This documentary follows the Clark Michigan 675 from the drawing board to the scrapyard. A 175-ton machine with a 24-cubic-yard bucket, twin Cummins V12 engines, and four tires taller than a man. We break down the square-cube problem that made it possible, the single-point-of-failure economics that made it dangerous to own, the 1973 oil shock that wrecked its timing, and the verified reason it lost to Caterpillar's smaller 992 despite being years ahead. It ends with the three machines that survive today, and the one that still runs. More from Construction Legends: 🛞 He Had 299 Patents and Caterpillar Laughed At Him (R.G.
