The first bulldozer was invented in Morrowville, Kansas in 1923. Bulldozers became popular because of an ability to move around a large amount of material at once and ability to break ground. Companies that manufacture bulldozers include Case, JCB, Terex and Caterpillar. Today, the first ever bulldozer is still on display in the town it calls home, Morrowville, Kansas.
