The principle of operation and the device trimmer for grass
Grass trimmer is a garden tool for cutting green vegetation with a soft stem and not thick dead wood. Unlike lawn mowers, the devices have a small weight and are worn by the operator on belts, and do not roll on wheels on the ground. Light weight makes it easy to transport the devices to the place of work and quickly move from site to site.
Using the cutting part of the trimmer, you can:
- maintain a low grass height on the lawn;
- mow it between houses and along paths;
- remove deadwood thickets near the carriageway;
- cut vegetation directly under the fence;
- cultivate the green shores of ponds.
Trimmers have a low cost, unlike lawn mowers, and increased maneuverability makes them more convenient to use. Both residents of the private sector and utilities, as well as enterprises, buy such an instrument in order to take care of the existing territory.
The operation process of the garden tool consists in putting the case on the operator’s body through special belts. The trimmer head is brought to the grass and the button on the handle starts the engine. Torque is transmitted to the bobbin through a rigid shaft in the apparatus tube. The head contains a cutting element that cuts grass stems at high speed.
To prevent impacts on solid objects and sticks flying out in the face, a protective cover is provided, covering 40% of the circumference of the diameter of the action of the cutting part of the tool.
Most modern trimmers have the following device:
1. motor (electric or gasoline);
2. fuel tank (in the case of an internal combustion engine);
4. handle for direction (1-2 pcs);
5. a rigid shaft for transmitting rotation from the motor;
6. a bobbin with a cutting element (fishing line or knife);
7. protective cover;
8. belt fastening.
Types of Grass Trimmers
The cutting unit of the trimmer has a removable or non-removable design. Depending on this, the functionality of the models differs. But all trimmers are divided into three categories.
This type of tool works from a household network in 220V. The electric motor rotates the shaft and starts the cutting mechanism. To use the device, an outlet and carrying device must be nearby. This partially hampers the maneuverability and scope of the tool, but allows you to work silently.
Still, such a device has no harmful emissions into the atmosphere. Such models are well suited for summer cottages and private firms with a small territory where you can get by with just one carrying coil.
- make little noise and do not interfere with neighbors;
- there are powerful models;
- no harmful emissions;
- handle height adjustment;
- the possibility of setting different knives.
- inconvenience from a wire that can be accidentally cut;
- limited area to carry length.
The principle of operation of this type is similar to electric, but rotation here is provided by an internal combustion engine. To do this, an additional tank with fuel is attached to the rod, as a result of which the device receives a large mass.
With such a tool, you can freely move around the territory and even work where there are no buildings and electricity. There is no need to constantly remember the cord and be careful not to cut it. It is actively used for mowing grass on the sidelines, maintaining the beautiful condition of yards in high-rise areas and in large enterprises.

- replacement of knives;
- no area restrictions;
- high performance;

Grass trimmer selection options
Understanding the key features of a garden tool, you can choose a model that is well suited to specific tasks and does not cause unexpected problems. Here are the main options for choosing grass trimmers.
The trimmer power rating is indicated in kW and affects performance. The higher this value, the faster the cutting element will rotate and the larger the area will be processed.
1. Garden tools can have a small indicator of 0.25 kW and reach 1.8 kW.
2. For utility services to care for the adjacent territory in the quarters and along the roads along the roadsides, where you have to work all day and mow large volumes of grass, it is advisable to purchase models 0.9-1.8 kW.
3. For giving and caring for a small lawn, an engine with parameters of 0.25-0.7 kW is enough.
The length of the knife and the possibility of maximum extension of the fishing line affect the width of the cut. The last parameter is limited by the dimensions of the protective casing. There are various models whose range can be from 200 to 420 mm.
1. For continuous lawns over a large area, trimmers with a cutting width of 300-420 mm are suitable.
2. 250-270 mm are enough for a summer cottage and care for the blocks of high-rise buildings.
The mass 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 models lighter for long-term employment, but often this involves remote work from the mains, which requires the most difficult gasoline models.
1. If you can connect to the mains, you should buy electrical devices weighing 3-5 kg.
2. For the cottage, an option of 2.5 kg is suitable.
3. If it is impossible to connect to the mains, you should buy gas trimmers with a weight of 7-9 kg.
Another performance indicator is the cutting speed of the cutting element in one minute.
1. In low-power versions, this parameter is not prescribed because there they are below 7000 per minute.
2. professional models have an acceleration of 7,500-12,000 rpm.
3. For a summer residence or a small business, 6000 rpm is enough.
4. For large volumes of work, 9000-12000 rpm is required.
Diameter of fishing line
This indicator varies from 1.4 to 3.3 mm and indicates the ability of the cutting element to cut through a certain thickness of the stem and branches of the bush.
1. 1.4-2 mm is enough for a summer yard, which will allow you to remove grass and maintain a neat appearance of lawns.
2. Workers who monitor the condition of the curb, where dense grass often grows, need to purchase 2.4-2.7 mm.
3. To improve the neglected area, a strong fishing line of 3.0-3.3 mm is required, capable of dissecting the stiffened stems and bushes.
Trimmers work by rotating the cutting elements, which can be thick knives (metal, plastic) or soft fishing line (cord).
1. Thick knives are more suitable for a flat open landscape and dense grass with hard stems. The tool will create an even cut. This type is practical for lawn care along businesses and next to a private home.
2. Fishing line is necessary in case of work on the hilly terrain and near fences. Beating against solid obstacles will not cause damage, and contact with the ground will not stop the process. But such trimmers do poorly with dense vegetation and get confused.
Type of fastening
To operate the device, it is hung on the operator’s case. For this, one or two belts are provided.
1. The use of a trimmer with a single belt is used to give or ennoble a small area of the company.
2. In the case of a large area, a satchel mount will be required to evenly distribute the load and reduce vibration.
The shape and number of handles, as well as the balancing of the device, are responsible for this.
1. The main and auxiliary handles are convenient for short-term use in a garden or a small company. To work all day, it is better to purchase models with a cross frame and two equivalent handles.
2. The position of the engine below the cutting part increases the load on the back and is suitable for mowing only for several hours. If the engine is installed at the top of the rod, this makes it easier to control the tool and is suitable for professional use.
Tank volume and battery capacity
In the case of autonomous fuel trimmers, tank capacity plays an important role. It happens from 0.3 to 1.5 liters. Manufacturers calculate its volume based on the ability of the engine to work continuously for a certain amount of time.
1. With a minimum tank, it will be possible to mow for 20 minutes, after which a stop for a break will be required to cool the motor and refuel.
2. It is possible to work with a maximum rate for more than an hour, which is convenient for commercial use in large areas.
For battery models, the battery is measured in amperes / hours. 1st unit A / h is enough for 15 minutes of work. Charging will require three times as much time.
1. For cosmetic care of a small lawn away from the outlet, 2 A / h is enough.
2. To care for the territory of a kindergarten or a small company, 3-4 Ah / h is required.
Which grass trimmer to choose
1. To work on uneven terrain along the fence, you will need a device with a fishing line of 2.7 mm thick. For productivity, a cutting width of 250 mm and a speed of 7500 per minute are sufficient. The device will be more convenient to operate with two equivalent handles. If the size of the territory allows the use of an extension cord, it is better to purchase a model with an electric motor.
2. In utility companies, on the balance of which there is a large territory with paths and courtyards, as well as road services, a trimmer working on gasoline with a tank of 1.5 liters, 12000 rpm, with a power of 0.9-1.6 kW, will be required, 300 mm wide and 3.0 mm thick fishing line.
