A '''bulldozer''' or '''dozer''' (also called a '''crawler''') is a large [[tractor]] equipped with a metal [[#Blade|blade]] at the front for pushing material ([[soil]], sand, snow, rubble, or rock) during [[construction]] work. It travels most commonly on [[continuous track]]s, though specialized models riding on large [[Heavy equipment#Traction: Off-the-road tires and tracks|off-road tires]] are also produced. Its most popular accessory is a [[#Ripper|ripper]], a large hook-like device mounted singly or in multiples in the rear to loosen dense materials. 

Bulldozers are used heavily in large and small scale construction, road building, [[mining]] and [[quarrying]], on farms, in [[heavy industry]] factories, and in military applications in both peace and wartime.

The word "bulldozer" refers only to a motorized unit fitted with a blade designed for pushing. The word is sometimes used inaccurately for other [[heavy equipment]] such as the generally similar [[Loader (equipment)|front-end loader]] designed for carrying material rather than pushing it. The term originally referred only to the blade attachment but is now commonly applied to any crawler tractor with a front-mounted blade.
