What is a "bulldozer"?

A bulldozer is a large, powerful piece of heavy machinery equipped with a broad, flat blade at the front, designed for pushing, moving, and leveling earth and debris. It is commonly used in construction, mining, and landscaping projects to clear land, create roads, and prepare sites for building. Bulldozers can operate on various terrains and are often fitted with tracks instead of wheels for better traction and stability on rough surfaces. Their ability to move large quantities of material makes them essential for many types of heavy-duty work, helping to reshape and prepare landscapes efficiently.
