Terms of the Trade: What Is a Brush Hog?

Lead Image

Also sometimes referred to as a bush hog, this large piece of agricultural machinery is a rotary motor attached to the back of a tractor, used to mow large areas of dense grass. Unlike a standard lawn mower that cuts with a sharp blade, a brush hog utilizes dull wedge-like blades to quickly cut through dense vegetation (a sharp blade typically slows down when it crosses a rock or other hard object in its path). Also unique to the brush hog's design is the use of centrifugal force to cut through any vegetation that may bounce across its path.
