A brushcutter (also called a brush saw, clearing saw or gasoline goat) is a powered garden or agricultural tool used to trim weeds, small trees, and other foliage not accessible by a lawn mower or rotary mower.
It consists of: There are three main types of power unit:[citation needed] There are three types of shaft:[citation needed] Handles vary on brush cutters, depending on the weight and size of the unit.
Larger, more powerful brushcutters employ handlebars — a handle on either side of the shaft, similar to bike handlebars — whilst smaller units use a D-shaped handle mounted on the shaft.
Most brushcutters also allow other heads to be fitted, including bump feed and fixed line heads such as those used on line trimmers or modified saw blades such as a beaver blade which resembles a chainsaw.
[citation needed] Plastic or metal flails can be used for cutting stems too large for a line head but not requiring a blade.
