You don’t have to hire a gardener to have a well-maintained green lawn. If you decide to get your site into proper shape on your own, all you need is a brush cutter or a grass trimmer. Due to their versatility, such tools can be used not only for cutting and leveling grass but also for creating landscape design elements. Choose to walk behind string trimmer self propelled.
Models of brush cutters and trimmers differ in technical characteristics, scope, as well as individual functional features. In this article, we will talk about the main features of the brush cutter, what types they are divided into and which is better – an electric or a petrol cutter.
Appointment of brush cutters and trimmers
A brushcutter and a trimmer are very similar and are primarily intended for lawn care, but there are some differences between the two.
The grass trimmer is often used to maintain small areas of the lawn, or to perform simple and short-term work.
This instrument is low power and is designed for soft grass. Grass trimmers can be equipped with both petrol and electric motors.
A brushcutter is a more serious tool that can cut thick and dense grass. Structurally, the brushcutter is a bar with an engine on one side and a set of cutting tools on the other.
The cutting components include the cutting disc, knife and line. The fishing line is used to level the lawns and work with the thinnest grass, while the knives cut the densest grass.
Types of brush cutters
String trimmer are divided into two types: professional and household. Professional brush cutters are designed for long periods of operation, while household brush cutters are used for short periods of time in small areas.
Professional brush cutters
Professional brush cutters are characterized by high performance and are able to work smoothly for a long time.
In addition to serious technical characteristics, these devices have a high build quality and improved case ergonomics.
Professional brush cutters are able to withstand increased loads and are used, as a rule, to solve complex problems in the arrangement of garden and park areas.
Professional brush cutters are equipped with a non-separable bar, inside which there is a shaft – the drive of the cutting element. Such a constructive solution makes the brush cutter sufficiently large, which creates inconvenience during its storage and transportation.
At the same time, this arrangement provides an important advantage – the isolation of the main elements of the tool from dust, debris, and various dirt, which has a positive effect on the service life.
Household brush cutters
Household brush cutters differ from professional ones in more compact sizes. As a rule, they are not designed for long-term stress and are used to care for small garden areas. The power of household brush cutters usually does not exceed 2 hp, while for a professional tool this is the minimum figure.
Household brush cutters can be equipped with both a trimmer attachment and steel knives and can differ in the type of shaft: with a flexible shaft and with a straight shaft. In addition, household brush cutters can be equipped with both a curved bar and a split bar.
Models with a split boom are not only lighter but also simple and easy to use.
View of the brushcutter handle
Brush cutters can be equipped with different types of handles. There are three main types of handles: D-shaped, T-shaped, and J-shaped.
This type of handle is the most convenient and compact. The D-handle is ideal for small workloads and allows for good maneuverability and speed.
T-handle is suitable for large amounts of work in open areas. Brush cutters equipped with this type of handle can be used not only for cutting grass on lawns, but also for carrying out important field work.
J-handle can be used in addition to the D-handle to prevent damage to the bevel gear.
Before choosing a brushcutter or trimmer, it is worth familiarizing yourself with another important parameter – the type of drive. Brush cutters and trimmers can be equipped with both electric and gasoline engines.
Brush cutters and trimmers with an electric motor
Brush cutters and trimmers with mains-powered engines are lightweight, produce no exhaust fumes and operate quietly.
These devices are especially relevant when improving recreation areas, sanatoriums and other places that require minimal noise during operation.
The only significant drawback of such devices is the need for a continuous connection to the network.
Brush cutters and trimmers with petrol engine
In domestic conditions, gasoline brush cutters and trimmers are today almost replaced by electric ones, however, despite this, this tool is widely used for professional use.
The main disadvantages of these devices are increased vibration, rather large weight, and noise during operation.
However, gasoline engines are more powerful and efficient and, unlike electric models, are not limited by the availability of the network.
What to look for when choosing brush cutters and trimmers
When choosing a brush cutter, we recommend that you, first, pay attention to the resource of work. Each manufacturer sets a designated resource and the higher this indicator, the more reliable this model.
Various modifications differ in the type of the drive shaft, the type of motor, the rod, the cutting element, and the availability of accessories.
To one degree or another, these differences are determined by the intended purpose of a particular instrument. For example, for small lawns, brush cutters with a straight bar and T-handle, based on a two-stroke engine, are the best option.
Whereas with a curved bar it will be more convenient to handle hard-to-reach areas (for example, between trees, under benches, etc.)
3. Weight and power
Usually, increasing power will increase the weight of the brushcutter. If you have a small area, there is no point in buying a heavy and powerful machine.
4. Anti-vibration system
It is important to remember that prolonged use of a vibrating instrument has a negative effect on the joints. Therefore, when choosing a brushcutter with an internal combustion engine, check if it has an anti-vibration system.
The efficiency of the brushcutter largely depends on the correct choice of the cutting attachment. For young grass, a line or a two-toothed knife is the best option.
A more effective and popular attachment is the three-pronged knife, which can cut even tough weeds. With the help of four-toothed knives, you can cut young tree shoots and undergrowth.
In case you purchase a brush cutter for haymaking, you should stock up on eight-toothed discs. They mow perfectly any grass, chopping it up with minimal damage.
Small trees and bushes with a stem section of up to 40 mm can be effectively cut with the 24- and 80-tooth knives.
Which is better?
- Brush cutters are more mobile as they do not need an external power source. If you have a large plot, this can be a significant advantage;
- The string trimmer needs to be filled with gasoline, while in order to start the electric, it is enough to simply plug it into the outlet and press the button;
- The brush cutter requires periodic maintenance. Maintenance with the replacement of consumables – for example, replacement of spark plugs, whereas the electric scythe requires only routine cleaning and lubrication;
- The tank of a household brush cutter is usually designed for 1-1.5 hours of operation – after that, it is necessary to interrupt the process and refuel. With the electric scythe, you can work without interruption at least the whole day;
- The brush cutter is significantly noisier than the electric one;
- When working with an electric scythe, it is important to constantly remember the presence of wire and calculate your trajectory so as not to accidentally damage it;
- The scythe mow can be mowed in any weather, while the electric scythe can only be used in dry weather;
- The electric braid has no exhaust, it is environmentally friendly.
