With authorities in various states as well as in the capital bringing in bulldozers to assert their power over poor people, the clunky, ugly earthmoving equipment has suddenly become part of our daily lexicon. Not for the first time, though. Just over 45 years ago, Delhi’s Turkman Gate was a witness to their destructive capabilities.

But the bulldozer as an idea has always had a life beyond the construction site. We use it commonly and frequently, with areas like films, politics and sports filled with references to it.

Americans James Cummings and J. Earl Mcleod are usually credited with having invented bulldozers in 1904 in Kansas, though there is some doubt about how much their invention resembled the modern-day version of it. Originally it was just a large blade that could be attached to the front of a tractor and was a clumsy contraption, restricted in its movements since it couldn’t move in any direction except forward.

According to ThoughtCo’s History of the Bulldozer, at around the same time, UK-based Hornsby turned one of its wheeled steam traction engines to a tracklayer format. Hornsby sold their patents to Benjamin Holt and it emerged as a refined piece of machinery after the Holt Manufacturing Company (later renamed the Holt Caterpillar Company in 1910) launched the Caterpillar Sixty. Bulldozer technically refers only to the shovel-like blade, though we now think of it as the entire vehicle. (Source: Bellis, Mary. "Famous Inventions: History of the Bulldozer."
