Once upon a time, people used shovels to move dirt. Then, around the 1920s, an awesome machine called a bulldozer was invented to do this heavy lifting.
A bulldozer is like a super-strong, giant robot. It is mostly used for moving large amounts of earth, rocks, or rubble from one place to another.
The bulldozer gets its name from the word “bull” because of its strength and “doze” from the word “dozer” which means to push. So, it is basically a machine that uses its strength to push things!
At the front of the bulldozer is a big, flat blade. This blade, powered by the machine’s engine, is the part that does all the pushing.
The bulldozer has huge, thick tires or tracks that can go over pretty much anything – dirt, rocks, even trees! Because of them, the bulldozer is really stable and doesn’t easily fall over.
Mostly, we see bulldozers at construction sites. There, they level the ground to make it ready for building houses, roads, or tall buildings.
Did you know this interesting fact? The bulldozer is almost like our superhero of the construction world. It does the tough work that would otherwise take lots of people and much longer time.
And that’s what a bulldozer is: a superhero, strength-packing, earth-moving machine! I bet you wouldn’t mind having a go at driving one, would you?
