During the operation of the trimmer, vibrations occur, which is generally characteristic of any mechanism, the individual elements of which perform rapid reciprocating movements. Vibrations can cause the operator to experience noticeable discomfort during work, and with frequent use of the tool, he can develop health problems, the most predictable of which is premature wear of the elbow joints.
A special anti-vibration system will help to significantly reduce the vibration effect on the body of a person working with a trimmer. In the simplest and most common version, it is a set of polymer spacers located between different structural elements of the trimmer.
Anti-vibration system for lawn mowers.
Such gaskets reduce the transmission of vibrations and thus ensure normal working conditions for the user with the tool. Often, manufacturers to damp vibrations additionally separate the engine from the boom with special shock absorbers. Almost all the world’s leading brands equip their products with anti-vibration systems.
Determining the type of gasoline trimmer
All trimmers and lawn mowers available on the market today, depending on their capabilities and purpose, are divided into three classes: household, semi-professional and professional. What tool do you need? It depends primarily on the tasks that will be entrusted to him.
Additional amenities. Belt system
Only a good shoulder strap can reduce the load on the arms when working with a rather heavy hand tool, which redistributes part of the weight to the operator’s back and shoulders.
Shoulder harness system. For comfortable use of this light household trimmer, a simple one shoulder strap is sufficient. If you have to work as a semi-professional or professional lawn mower, we strongly recommend looking after products with double shoulder belts.
Knapsack belt systems, although they are more expensive, distribute the weight of the tool more evenly on the shoulders and back of the user, which means that they significantly reduce fatigue during hours of weed control.
These Backpacks are often equipped with special bags for storing cutting equipment, as well as tools, which may be needed to repair the trimmer in the field. And a special pad, which manufacturers supply the belt system, protects the operator’s thigh from burns when it comes into contact with an engine that is very hot during operation and reduces the level of transmitted vibration.
Fuel tank volume
The capacity of the tank for the fuel mixture can vary from 0.3 to 1 liter, depending on the model. Trimmer with which gas tank. large or small. to give preference? Both options have their advantages and disadvantages. A large tank increases the weight of an already heavy unit, but does not require frequent stops for refueling.
A tank with a smaller capacity, in turn, is less overall and heavy, contributes to more economical fuel consumption, but at the same time does not allow for long-term non-stop operation. When choosing a trimmer for such a parameter as the volume of the fuel tank, you should be guided by your physical abilities and the size of the area, which you will regularly mow. It is very convenient if the fuel container is made of translucent plastic. this allows you to track the amount of fuel remaining in it during operation.
How to choose a petrol grass trimmer for your home garden? And for processing a “plantation” of a couple of hectares? That’s right, focusing on its power.
The trimmer-mounted petrol engine can range from 1 to 3-3.5 hp. The choice of a tool for this parameter directly depends on the expected load. It is the trimmer power that determines its operational purpose. So, for mowing the lawn next to the house, a simple tool with a capacity of no more than 1.5 liters will be enough. From. A more powerful engine is installed on farm trimmers. from 1.5 to 2.5 liters. From. The whole range of trimmer capabilities can only be demonstrated by a professional tool with a power of more than 2.5 hp.
It is clear that an increase in the power of the tool inevitably entails an increase in its weight and cost. It follows from this that when choosing it is not necessary to mindlessly chase high power indicators, but to focus primarily on the planned scope of the tool.
Four-stroke engines are devoid of almost all the disadvantages inherent in two-stroke engines: they produce much less noise during operation, the volume of exhaust gases in them is much lower, and gasoline and engine oil are poured into different containers.
They are more economical in terms of fuel consumption and have a higher service life. All this, however, does not mean that four-stroke ICEs are ideal. Comments, they have their drawbacks.
The design of such an engine is more complex, which means that both its maintenance and its repair are more difficult. A four-stroke will always be heavier than a two-stroke equal in power, which negatively affects the weight of the entire instrument and, consequently, the convenience of handling it. And finally, a trimmer equipped with a four-stroke engine will be more expensive than the same trimmer, but with a two-stroke ICE.
It should be mentioned that along with classic four-stroke engines, there are also hybrid ones: the working cycle in them occurs in 4 strokes, however, the lubrication system is the same as in a conventional two-stroke engine.
Professional, or landscape gardening
The professional trimmer is a powerful tool for urban landscaping, landscaping and utilities. It is equipped with an engine with a power of over 2.5 HP, has an increased service life and is ready for many hours of daily work. In addition to the trimmer head, such units can be equipped with metal knives that can cope with dense shrub growth and unnecessary tree shoots with a trunk thickness of up to 3 cm in diameter.
It is not hard to guess that professional trimmers have a reinforced bar and a spacious fuel tank. Since such tools are quite massive, they are necessarily equipped with special belts, which lighten the load on the operator’s hands, and a professional vibration damping system. It is clear that purchasing a professional lawn trimmer next to a private house is simply inappropriate.
Almost all trimmers are equipped with a trimmer head. a reel designed to wind the cutting line. According to the method of feeding the line, all trimmer heads are divided into mechanical (you have to pull the ends of the line yourself manually), semi-automatic (the line is released by pressing a wide button on the lower plane) or automatic (lengthening of the protruding ends of the line occurs automatically when the engine speed decreases). Semi-automatic cord feeding is considered the most efficient, such heads are the most popular among users.
In addition, trimmer heads can differ in the maximum allowable diameter of the mowing line that can be tucked into the reel. On household trimmers, a fishing line with a diameter of 2 to 2.4 mm is usually installed, on semi-professional. that’s 2.4 to 2.7 mm, on professional. that’s 2.7 to 3 mm.
When choosing a trimmer head, be sure to pay attention to the material from which the lower part is made. It is this part that is the most vulnerable, since it constantly hits the ground, it is this part that is especially often the prerequisite for the failure of the trimmer head.
For mowing especially dense grass, reeds, shrubs, young growth of trees, they use NOT fishing line, but special knives (cutters). On sale you can find a huge number of varieties of trimmer knives, differing in material (metal or plastic), shape, number of cutting blades. By the way, cutters, unlike fishing line, DO NOT crumble the grass, which means they can be used for Mowing for procurement purposes.
Which knife to choose for your trimmer? When solving this issue, first of all, one should be guided by the recommendations of the manufacturer, indicating the possibility of using one or another type of equipment on this model. Excessive independence in the choice of knives and cutters can lead to the failure of the trimmer.
Which grass trimmer to choose
To work in uneven terrain along the fence, you will need a device with a 2.7 mm line. For productivity, a cutting width of 250 mm and a speed of 7500 rpm are sufficient. The device will be more convenient to operate with two equivalent handles. If the size of the territory allows you to use an extension cord, then it is better to purchase a model with an electric motor.
Utilities, which have a large area with paths and courtyards on their balance sheet, as well as road services, will need a petrol trimmer with a 1.5 liter tank, 12,000 rpm, 0.9-1.6 kW power, width coverage 300mm and line thickness 3.0mm.
For a large private area or enterprise with green areas, you need to buy a garden tool with an internal combustion engine of 1 kW, 10,000 rpm, an iron blade or a fishing line of 2.4 mm and a cut width of 420 mm.
In a small courtyard for a summer cottage, an electric model with a power of 0.25 kW, 6,500 rpm, a line thickness of 1.4-2.0 mm, and an area coverage of 250 mm along the cut width is enough. Mounting method will fit on one belt with the lower engine location.
To care for the territory of kindergartens, boarding schools and recreation centers, it is practically possible to buy battery versions that silently perform their functions over a vast territory. A model with a power of 0.7 kW, a battery capacity of 3 Ah, 7500 rpm and a line of 2.0 mm will do.
Types of grass trimmers
The trimmer cutter assembly is removable or non-removable. Depending on this, the functionality of the models differs. But all trimmers fall into three categories.
A less common type of garden tool is electric powered trimmers but battery powered. This allows you to cut the grass just as quietly, but does not depend on the length of the carrier.
Due to the limited use of time, such models are bought to care for a summer cottage where there is no electricity or to improve the territory of kindergartens and similar institutions.
- Setting of different cutting systems;
- There are restrictions on the area;
- Energy reserve is enough for 30-45 minutes;
- Fast charging;
- Powerful models available.
- Operating time is limited by battery capacity;
- Are more expensive than electric.
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 fuel tank is attached to the Rod, due to 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. All the need to constantly remember about the cord and are afraid of its sections. It is actively used for mowing grass on the side of the road, maintaining the beautiful condition of courtyards in multi-storey areas and on the territory of large enterprises.
- Powerful models;
- Replacement of knives;
- Comments on area restrictions;
- High performance;
- Reliable design;
- Wide area of commercial use.
- Additional fuel costs;
- Air emissions.
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 hard stems. The tool will create an even cut. This type is practical for lawn maintenance along enterprises and next to a private house.
The line is necessary when working on hilly terrain and near fences. Beating into 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.
This indicator varies from 1.4 to 3.3 mm and indicates the ability of the cutting element to cut a certain thickness of the stem and branches of the shrub.
For a summer cottage, 1.4-2 mm is enough, which will allow you to remove grass and maintain a neat appearance of lawns.
Employees who monitor the condition of the roadside, where thick grass often grows, need to purchase 2.4-2.7 mm.
For the improvement of a neglected area, a strong fishing line of 3.0-3.3 mm is needed, capable of cutting through stiff stems and bushes.
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.
Garden tools can have a small figure from 0.25 kW and reach 1.8 kW.
For utilities for the care of the local area in neighborhoods and along roads along the side, where you have to work all day and mow large amounts of grass, it is advisable to purchase models of 0.9-1.8 kW.
For giving and caring for a small lawn, an engine with parameters 0.25-0.7 kW is sufficient.
Ease of holding
The shape and number of handles correspond to this, as well as the balancing of the apparatus.
The main and auxiliary handles are convenient for short-term use in the garden or small company. For all-day operation, it is best to purchase a model with a cross frame and two equivalent handles.
Positioning the motor down above the cutting head increases the load on the back and is only suitable for mowing for a few hours. If the motor is mounted on the top of the boom, it makes it easier to control the tool and is suitable for professional use.
To operate the device, it is hung on the operator’s body. One or two belts are provided for this.
The use of a single belt trimmer is used for giving or beautifying a small company area.
In the case of a large area, a knapsack mount is required, which evenly distributes the load and reduces vibration.
