A brush hog is a type of rotary motor that is used to cut down heavy grasses and brush. The blades of a brush hog are usually thicker and more blunt than the blades of regular mowers. They are also attached to the drive differently than regular lawn mower blades to accommodate large obstacles, like rocks. Most brush hogs are attached to the backs of large tractors, and the blades are driven by special drive shafts on the backs of the machines.
Rotary mowers are typically used to cut grass and brush. They usually consist of a drive with large blades attached. When the drive rotates, the blades swing around, cutting the vegetation. On some rotary mowers, these blades can be quite sharp.
The blades of a brush hog are usually not as sharp as the blades on a regular mower. Instead, they are usually somewhat dull. In fact, these edges are typically shaped like a wedge, similar to that of a splitting maul. This type of edge makes it much easier to cut thicker vegetation.
A brush hog is not usually used for regular lawn mowing or thin grasses. Instead, as its name suggests, it is used to cut down brush and thick grasses. Some brush hogs are also capable of cutting down small shrubs and trees.
On a regular mower, the blades are directly attached to the drive that helps turn them. On a brush hog, the blades are often attached to the drive with hinges. These hinges allow the blades to bounce up when they hit a rock or other hard obstacle.
Most types of brush hogs attach to the back of large tractors, like farm tractors. The blades are powered by something known as a power take-off on the back of these tractors. This is a drive shaft that comes out of the back of the machine, and it can be hooked to a brush hog. When it is hooked up, the blades of the brush hog spin.
Brush hogs are often towed behind tractors, attached to a hitch. Some can be attached to hydraulic lifts that can be found on some tractors. Typically, brush hogs that are attached to hydraulic lifts are easier to maneuver into tight corners and spaces.
A brush hog can also come in a variety of sizes, from a few feet (1 meter) wide to over 20 feet (6 meters) wide. The size of the brush hog mainly depends on the size of the brush to be mowed and the size of the tractor pulling it. For instance, small tractors will not usually have enough power to pull very large brush hogs.
