Rules for choosing a benzotrimmer

Gasoline trimmers, like electric, are designed for mowing grass, harvesting hay, removing weeds, and treating small bushes. With compact and easy-to-use devices you can remove vegetation in hard-to-reach places where it is impossible to use a lawnmower - around trees, near buildings, near garden paths. Powerful models can even produce a rough treatment of shrubs and small trees.

Tool features

Gasoline unit for mowing the grass is called differently: gasoline trimmer, mowing, benzokosa or even a lawnmower. The name does not always determine the use of technology. In fact, some manufacturers try to somewhat characterize their products,selecting informative names that do not change the essence: a benzotrimmer or a motokosa (benzokosa) may have similar characteristics.

What is different from the trimmer actually trimmer, so it is characteristics: gasoline spit more powerful, always equipped with a cutting knife or disc. A benzotrimmer, in turn, can only be equipped with a fishing line, sometimes with a replaceable knife. Trimmers are often lighter, more compact, there are even models with a collapsible bar (the connection of two bar elements is considered a weak point, therefore professional versions always have a good monolithic construction).

Based on the design features and technical parameters, gas trimmers are great for private use in the country, in the garden, on the territory of the cottage. They are convenient to trim small lawn grass, cut thin stalks of weeds or other vegetation.

Gasoline spit, depending on the power and layout, is applied for work on a small private farm, for the improvement of streets and local area around apartment buildings.Such a model is also suitable for an individual if the size of the plot exceeds 20 acres, and the amount of work is large.

Specifications

When buying, a large role is played by the design and technical equipment of the unit. Equally important is ergonomics, because not all types of trimmers are comfortable to hold in their hands for a long time. The “dry” mass of some gasoline mowers can reach 9.5 kg, and even a small constructive detail can affect the comfort of use. To determine which trimmer is best to buy, you should pay attention to the key parameters of a particular model.

engine's type

The vast majority of gasoline trimmers and motokos are equipped with a two-stroke engine, in rare cases the manufacturer installs a four-stroke. The difference in the principles of work is not so important, because as a result, the user receives the same thing - a benzo unit for mowing the lawn and weeds. However, when buying, you should understand the practical differences between 2T and 4T engines, this can affect the choice of a suitable model.

1. Service. In the 2T engine pour pre-cooked mixture of gasoline and oil.In the configuration, as a rule, there is a measuring capacity, and in the technical description the recommended proportions are indicated. Before starting the 4T engine, oil and gasoline are poured into separate tanks, which is somewhat simpler in theory. In practice, mixing the mixture in a bottle or pouring it into different compartments is equally easy, but servicing 4T engines means more operations.

2. Comfort at work. The petrol trimmer with a 4T engine really works quieter than a push pull. In fact - this is the only good reason to purchase such a model.

3. Vibrations. It is believed that 4T engines vibrate less, but this concerns only two-cylinder engines, single-cylinder 2T and 4T are approximately equal in terms of vibration. But among the small benzokos with the 4T engine, almost all models are equipped with an additional vibration damping system - it is at this point that one should pay attention. The second factor is the quality of balancing, “noname” brands do not always differ in compliance with assembly rules. Here you should give preference to reliable manufacturers - Stihl, Husqarna, Makita, Hitachi.
   

Conclusion: for household purposes or a small household, an aggregate with a 2-stroke engine is also suitable, but if the increased noise will cause severe discomfort - you should choose a model with a 4-stroke engine. Among the most powerful representatives in its class there are both 2-stroke and 4-stroke ones - here it is preferable to choose the second option. Such devices are almost always equipped with various vibration reduction systems, moreover, the 4T slider lasts a little longer.

Power factor

The power of benzoagregatov measured in hp, and in fact, this figure determines what the load can withstand technology. The choice here is influenced by the specifics of the upcoming work, the area of ​​the plot, the intensity of use.

Power classification of petroltrimmers:

• low-power trimmers - 0.9 - 1.1 hp;
• average power benzocos - 1.2 - 1.7 hp;
• powerful benzokosy - 1.7 to 3.0 hp

Low power trimmers are intended only for grass on the lawn or small weeds. The unit will not be able to cut off the thick stems: the line will “iron” the vegetation, and when using a knife or a disk in the engine, the speed will be reduced. For tall, thick shoots are used. medium power or powerful models, the latter can be made even rough processing of shrubs and young trees, although for such works it is better to use a brush cutter.

Cutting part - fishing line, knife or disc

Equipment for benzokos are nozzles with fishing line, knife or disk. Completion of lightweight devices can only include a cord with a fishing line, in all other cases a knife or a disk goes along with the trimmer.

Korda (fishing line)

When working with small grass, it is enough to use a fishing line; its feeding can be fully automatic or semi-mechanical. In the second case, to submit the fishing line, press the button located on the base of the cord.

Metal knives and discs are more practical, productive and wear-resistant. They should be used to mow grass for hay or to remove high, dense thickets.

Knife and disk

It is important to know! Cutting knives or discs must not be sharpened by yourself. In living conditions, even with the use of highly specialized equipment, it is almost impossible to achieve uniform material removal, which leads to an imbalance of the disk. Use of such equipment leads to engine breakdown.

On the type of working body depends processing width - performance. The larger the index, the faster the removal of thickets.

Design and ergonomics

The mass of the benzoagregat for mowing grass is from 4 to 9 kg. First of all, weight is influenced by power, engine size and fuel tank capacity. The comfort of operation will depend on the type of strap and grip.

The most compact and lightweight models are usually equipped with a simple loop-shaped handle on the bar, the equipment also sometimes includes a shoulder strap. It is understood that such trimmers work no longer than 20 minutes per cycle and no more than 2 hours per day, because little attention is paid to ergonomics: the loop-shaped handle is almost always plastic, without rubber linings, and the holding belt is narrow — about 3-4 cm in width.

Large and medium power tools are always equipped with an ergonomic handle of a bicycle type, but the belt hanger may be different: a knapsack or a shoulder. Knapsacks are the most comfortable, they have two wide shoulder straps, and they are worn like a backpack. At the same time, the entire load from the gas mowers is distributed evenly, which eliminates the operator’s rapid fatigue, and the load on the spine is reduced.Wide shoulder belts are often found in the semi-professional or farming class, they are much wider than with simple trimmers.

Sometimes the belt can be supplemented with an additional holding belt.

When buying even the lightest unit, it is better to choose a model equipped with a belt or buy a suspension separately. Additional fixation provides convenience and safety of operation.

Household or professional

Modern models are divided into household, professional and semi-professional (farmer). The key factor here is power combined with other technical characteristics - engine size, cutting width, tooling type, type of suspension and handles.

Three classes of benzotrimmers have different purposes.

• household perform minor work, suitable for giving or garden plot;
• "Farm" - equipment for small farms or households;
• professional motokos serve for processing of sites over 20 hundred parts or for improvement of streets.

In living conditionswhen the whole scope of work is reduced to trimming the lawn around trees or paths, there is no need for high productivity,and short-term operation does not exert excessive physical exertion. For such works, you can buy the most simple mower with a capacity of about 1 hp. Units of a household class differ in small weight, therefore, they are more maneuverable.

The trimmer has a fairly moderate fuel consumption, but the time of continuous use is limited to about 20 minutes. Exact data manufacturer indicates in the passport.

Semi-professional gas mowers suitable not only for grass, but also for high, dense thickets. The power of such a tool reaches 1.7 hp, the cut width is about 25 cm. The equipment of this class is designed for occasional large-scale work, for example, for harvesting hay, processing a large garden plot. The time of continuous work in such models is more - up to half an hour, but about once per hour the working body should be cleaned of accumulated grass. Thanks to average power and performance, these units handle the job faster.

Professional gasoline trimmers or benzokosy designed for long-term operation, but they have a higher consumption of gasoline.Often, such models are purchased for public utilities or organizations providing services for landscaping. High power is expressed in large mass, the daily use of such units for several hours requires maximum convenience: the mowers are equipped with durable, comfortable backpack straps, ergonomic handles of the bicycle type.
