The brushcutter is a garden operating machine. Although there are different types of brushcutters, the operation is always the same: a cutting accessory, which can be a head with the wire or a blade, with the movement generated by a normally combustion engine, it rotates quickly and cuts the grass, bushes and small shrubs quickly. Today the choice is wide and the models on the market are numerous. They are of many displacements and with different types of handles to choose according to the conditions of the work area. The handles are usually of two types: the most widespread are those with a single handle, which is used by placing the hands along the transmission rod, composed of the accelerator control located on the back of the rod and a donut-shaped handle which is located on the front. Then there are the handlebar grips, present above all in the professional models of large displacements, which are grasped like the handlebars of a bicycle, these handles allow you to better distribute the weight of your body.
How is a petrol brushcutter made?
The basic element of petrol-driven brushcutters is a single-cylinder petrol engine, generally two-stroke but recently some models with four-stroke engines have also been introduced on the market, which can be mounted in two different ways: directly attached to the rod transmission or backed. This latter type of engine is mounted on two shoulder straps which allow it to be worn on the shoulders like a backpack, a flexible rubber hose is connected to the end of the engine and inside there is a small transmission unit. This tube transmits the movement to the transmission rod. On the engine there are the air control, the fuel tank and in some models a pump that sends fuel to the engine to facilitate starting. Along the rod is the handle which can be of one of the types described in the previous paragraph, inside there is the transmission organ that turns the cutting accessory.
How to choose the brushcutter
A brushcutter is chosen mainly on the basis of the type of work one intends to do: for small gardens with a few square meters of surface area, a hobby model with a 30cc motor with a capacity of about 1kW or a little more may be sufficient. For large areas it is advisable to opt for a professional model with greater displacement and power so that the engine can withstand the hours needed. Generally an agricultural machine with a fixed rod is preferable as it is more practical to move, for fields with terraces or in any case on a slope, a model with a backed motor is more suitable as it is more anchored to the body. After evaluating the type of machine that best suits your needs before making the purchase, it is always advisable to inquire about the quality / price ratio of each individual model and to understand which manufacturers have a service center at hand to make sure you have chosen a product that can be satisfying and have the certainty of finding the right assistance in case of need. After that you can proceed with the purchase.
