 Bulldozer, also called Dozer, powerful machine for 

pushing earth or rocks, used in road building, farming, 

construction, and wrecking; it consists of a heavy, 

broad steel blade or plate mounted on the front of a 

tractor. Sometimes it uses a four-wheel-drive tractor, 

but usually a track or crawler type, mounted on 

continuous metal treads, is employed. The blade may be 

lifted and forced down by hydraulic rams. For digging, 

the blade is held below surface level; for transporting, 

it is held at the surface level; and for spreading, it 

is held above the surface level, as the tractor moves 

forward.

Bulldozers are used for shallow digging and ditching; 

short-range transportation of material; spreading soil 

dumped from trucks; rough grading; removing trees, 

stumps, and boulders; and cleaning and leveling around 

loading equipment. A bulldozer alone can do many types 

of excavation, and it is useful in combination with 

other machinery in most excavation work.

Most people don't realize this, but a bulldozer is 

actually classified first and foremost as a tractor! The 

difference between a dozer and a farm tractor comes from 

the metal plate (also called a blade) featured in the 

front of the bulldozer. Similar to a tractor, however, 

the bulldozer is used to push massive amounts of debris 

and raw material, including sand, rocks, dirt, and 

bricks.

Bulldozers work primarily thanks to the force exerted by 

their tracking system. The tracks that rotate around the 

bottom of the dozer, like a circulating belt, are 

responsible for its considerable resilience on tough 

terrain and its ability to transport and retain hefty 

loads.
