The principle of operation and the device of the grass trimmer

The grass trimmer is a garden tool for cutting green vegetation with a soft stem and not thick dead wood. Unlike lawnmowers, the machines are lightweight and are worn by the operator on belts rather than rolling on wheels on the ground. Low weight makes it easy to transport the devices to the work site and quickly move from site to site.

With the cutting edge of the trimmer you can:

  • keep the grass on the lawn low;
  • mow it between houses and along paths;
  • remove deadwood thickets next to the roadway;
  • cut off vegetation directly under the fence;
  • to cultivate the green shores of water bodies.

Trimmers are inexpensive compared to lawn mowers, and their increased maneuverability makes them easier to use. Such a tool is bought by both residents of the private sector and utilities, as well as enterprises to take care of the existing territory.

The process of using a garden tool is to put the body on the operator’s body using special belts. The trimmer head is brought to the grass and the button on the handle starts the engine. The torque is transmitted to the bobbin through a rigid shaft in the tube of the machine. The head contains a cutting element that cuts grass stalks at high speed.

Cutting width

The width of the cut is influenced by the length of the knife and the possibility of maximum extension of the line. The last parameter is limited by the size of the protective casing. There are various models, the range of which can be from 200 to 420 mm.

For solid lawns on a large area, trimmers with a cutting width of 300-420 mm are suitable.

For a summer cottage and caring for blocks of high-rise buildings, 250-270 mm is enough.

The weight of the device affects the ease of use and operator fatigue. The weight of the tool varies from 1.5 to 9 kg. Of course, it is logical to take lighter models for long-term employment, but often this is associated with remote work from the mains, which requires gasoline models that are the heaviest.

If you can connect to the mains, you should buy electrical devices weighing 3-5 kg.

An option of 2.5 kg is suitable for giving.

If it is impossible to connect to the mains, you should buy petrol trimmers with a weight of 7-9 kg.

Cutting system

Trimmers work by rotating cutting elements, which can be dense knives (metal, plastic) or soft line (cord).

Heavy knives are more suitable for flat, open terrain and dense grass with firm stems. The tool will create an even cut. This type is practical for the maintenance of lawns along enterprises and next to a private house.

The line is necessary when working on hilly terrain and near fences. Beating against solid obstacles will not cause damage, and contact with the ground will not stop the process. But these trimmers do not cope well with dense vegetation and get confused.
