Bulldozer | Educational Construction Vehicle for Kids | Letter B

Today we meet this huge yellow machine called bulldozer. You can see bulldozers on construction sites.
These machines can push sand, dirt and even heavy rocks.
They are very helpful during construction of new buildings, parks, and circus.
Instead of wheels, bulldozer has metal tracks.
Using these tracks bulldozer can move on any kind of the road, even there is no road at all.
For example, here is our bulldozer moving on sand… on mud… and on swamps

It is bulldozer’s blade. Using the blade bulldozer pushes everything on its way.
