A brush cutter is a tool that is used to cut grass, brushwood, bushes, young trunks and for general cleaning of the undergrowth. The cutting capacity varies according to the engine power and the configuration with which the tool is made. In some models the engine is mounted on a structure equipped with shoulder straps, which can be positioned on the shoulders, so that it can work in places that are difficult to reach. Usually these models are equipped with a flexible rod which further improves their handling. For the correct choice of a brush cutter you must understand its structure so that you can use the ideal tool for your needs, therefore also evaluating the amount of work to be carried out so that the performance of the tool is maximum.
Structure of a brush cutter
A brushcutter is made up of various parts that serve its operation and use. The engine is usually electric for those with a maximum power of 1000 watts, or fuel, generally two-stroke, for those who have to carry out more intense work and on larger surfaces. Some brushcutters can be four-stroke and are usually used for cleaning the woods. The rod is normally made of light alloys and has a diameter that can vary between 24 and 34 millimeters. Inside the external rod there is another one, positioned on self-lubricating bushings, in steel which is capable of transmitting the rotary motion. In the supported models there is an additional flexible rod positioned between the centrifugal clutch of the engine and the rigid rod, which is left free to rotate inside a sheath made of rubber.
