What is a lawn mower and brush cutter?

The blades of lawn mowers and brush cutters are the core components of two different devices, with the main difference being their purpose and structure:

lawn mower blade
Used for trimming lawns and vegetation, installed on a cutterhead and driven by an engine to rotate at high speed for cutting. Its structure includes a cutterhead, engine, walking wheels, and control system, which quickly cleans the vegetation in the area through high-speed rotating blades.  ‌

Brush cutter blade
Mainly used for clearing shrubs and weeds, with a greater emphasis on durability and cutting ability in terms of structure. Usually equipped in garden machinery, it is directly connected to the engine and completes shrub pruning and green belt maintenance work through high-speed blades.  ‌

Both achieve efficient operation through power drive, but the blades of the brush cutter usually use more durable materials and designs to cope with more complex shrub environments.  ‌
