A bulldozer or heavy excavating machine with an angled or adjustable blade designed for earth-moving work.
Compound of 'angle' and 'dozer' (short for bulldozer). Modern industrial term created in the 20th century for machinery with adjustable angled components.
The angle of a bulldozer's blade is crucial—push it straight and you move earth efficiently, but angle it and you can reshape landscapes or clear slopes that would be impossible to tackle head-on.
