A bush hog is a type of rotary cutter that is used to clear brush and tall grass from an area. It consists of a horizontal spinning blade or blades that are mounted on a vertical shaft in front of the operator, who controls the machine by holding onto handles on either side. The blades cut through vegetation as the bush hog moves forward, and the debris is thrown up and out of the way by the centrifugal force created by the spinning blades.
A rotary cutter, on the other hand, is a type of lawn mower that uses one or more rotating blades to cut grass and other vegetation. Unlike a bush hog, which has its blades mounted in front of the operator, a rotary cutter has its blades located behind the operator. This makes it easier to maneuver around obstacles and gives the operator a better view of what he or she is cutting. Rotary cutters come in different sizes and can be used for both residential and commercial applications.
