Engine Type

The engine-the most important element of a design. From it depends primarily on the performance of the tool and its life.

  • The four — in which the piston makes 4 turns per cycle. Gasoline engine oil enters the combustion chamber separately.

2-stroke

  • The small size and weight of the device.
  • A more economical, compared to 4-stroke models.
  • Do not require additional lubrication, as the oil in the engine comes already from the finished mixture.
  • Their service life is 2 times less than that of the 4-stroke.

Engine power

This setting affects the speed and width of mowing, and the type of vegetation, which would be able to operate this mower. All devices can be divided into 3 type:

  • Home (up to 1kW)-their use is recommended for occasional cutting low grass and weeds in small areas, for example, on the front lawn. With a heavy load such a device can not cope.
  • Universal (from 1 to 3 kW)-these models are already suitable for intensive cutting grass on the medium area of ​​the territory, in parks and gardens.
  • Professional (from 3 kW and above)-are suitable for continuous operation, this brush cutter is easy to cope with cleaning large areas of grass. With the help of these tools can also be hay, cut shrubs or growth of young trees.

The number of revolutions of the cutting system

Here it is necessary to take into account that the speed of rotation will be different when using a fishing line and a knife. This is due to the fact that the blades and discs are made mostly of metal, it increases the load on the engine at a set rate. Therefore, when using knives rarely maximum rotational speed exceeds the index of 7000 rev/min. At the cutting head and line main rotating elements usually made of plastic and have a smaller footprint. This allows them to spin faster in such petrol queues grass peak speed can reach the level of 10,000 rev/min and more.

Type of cutting system

Cut the grass in mowers are different cutting elements: woods, metal or plastic knives.

The line

This type is only designed for cutting small and young grass. Monofilament (nylon cord) may be of several types:

  • No reinforcement — it is quite strong and wear-resistant material, which is suitable for cutting fresh grass.
  • Reinforced — a feature that is within a more dense material, such as metal. This line was more rigid and very strong, able to withstand high loads. It is used only in high-end models.

In addition to the type, it is necessary to choose the right fishing line thickness (diameter). If it is very thick, it will increase the load on the engine, thereby reducing the number of revolutions. As a general rule, the manufacturer specifies the recommended diameter of the fishing line in the device user's guide.

You can also navigate to the following recommendations:

  • 1,6-2 mm — This line is suitable for low-power devices with an engine capacity of up to 750-800 W;
  • 2,4 mm — the most common size, which is suitable for most consumer devices;
  • 2,7 mm — recommended for semi-professional tools;
  • 3 and 3.3 mm — diameter of the monofilament is intended for professional brush cutters.

Usually monofilament is used in low-power model where the engine can not maintain a high metal blade speed. Due to lack of power in a knife device will slip, brake and stick in the grass.

Knives

They can solve more complex problems and can easily cope with the thick, old grass and shrubs and shoots of young trees.

Knives come in several types of form and function:

  • 2-tooth-they can be used to mow the young grass;
  • 3-tooth-excellent job with a tough grass and weeds;
  • 4 toothbrushes-are designed for cutting in dense thickets;
  • 8-tooth-their purpose-Hay;
  • Metal wheels-used when it is necessary to cut the bushes or woody growth.

Please note that the knives are also distinguished on the outside diameter. This should be considered when buying a knife should be suited to your model mowers.

It is also worth noting that there are some models that are used simultaneously both cutting system: the fishing line, and a knife. As a rule, it is a powerful and high-performance devices.

  • Direct bar — it usually has powerful and versatile model. Inside this handle is not used a thin rope, a sturdy tree, this brushcutter can work with any cutting elements and can tolerate high loads.

Brush cutters Weight

The weight of the device depends on various factors: the design features of the materials used and of course, the engine power. The most powerful model will be the most difficult. It is important to find a balance, as a heavy instrument to work harder than easy, but take the smallest is not always rational, so the petrol scythe grass can not cope with the task.

There are several weight categories:

  • From 4 to 5 kg-a compact model with a fishing line, used for mowing grass shallow. They are ideal for the care of a small lawn at the local area. With such a tool handle and a woman and a teenager and senior citizen.
