A brush cutter, also known as a brush hog or weed wacker, is a heavy-duty gardening tool used for cutting and clearing dense undergrowth, grass, and brush in areas that are difficult to reach with a lawn mower or other garden tools. Brush cutters are typically powered by gasoline or electricity, and come in a variety of styles and sizes, including handheld models and walk-behind models.

Handheld brush cutters are typically smaller, more portable, and more suitable for smaller trimming tasks. They are usually equipped with a flexible shaft and a cutting head that can be fitted with different blades to handle a range of cutting tasks. Walk-behind brush cutters are larger, more powerful, and more suitable for clearing large areas of brush and undergrowth. They typically have a cutting deck mounted on a set of wheels and are equipped with a cutting blade that rotates at high speed.

When choosing a brush cutter, it is important to consider factors such as the size and type of brush or undergrowth to be cleared, the amount of cutting required, and the availability of power or fuel sources. Additionally, it is important to choose a brush cutter with a blade length and cutting capacity that is appropriate for the task and to ensure that the brush cutter is equipped with safety features such as a safety switch to prevent accidental start-up and an anti-vibration system to reduce fatigue during use.
