With the arrival of the spring-summer season, all owners of suburban areas always face the same problem - caring for lawns and lawns and combating fast-growing weeds and wild bushes that make their way through. Ordinary scythe does not always become a good helper: first, to use it, you need some experience, and secondly, in close conditions of the site it is practically impossible to operate with such a tool between trees, bushes, benches, columns, curbs, etc.
In order not to resort to manual, very time consuming operations, it makes sense to purchase a trimmer, or, in other words - a motorized scythe, with an electric or gasoline drive. In the event that the lawn or lawn is located near the house, small in size, and they are not expected to work with a greater load, it may well be enough electrical appliance. But much more opportunities are available for mowing trimmers how to choose which - will be told in this publication.

How really flawlessly correct - hard to say. However, the second type of classification still seems more obvious and justified. Without claiming absolute truth, we will still adhere to the definition that a trimmer is a hand tool for mowing grass with an electric or gasoline power train.
Despite a very wide variety of models of gasoline trim tabs, most of them are made in a single circuit. As the power drive, an internal combustion engine is used, from which the torque is transmitted to the working cutting head. The illustration shows the main visible elements and components of the standard trimmer-trimmer:
1 is a gasoline engine located at the top.
2 - fuel tank.
3 - a manual starter for starting the engine.
4 - the rod connecting the engine with a working part of the trimmer. Inside the rod there is always a flexible or rigid shaft transmitting the rotation. The bar may be integral or demountable, consisting of two or more sections.
5 - handle, which can be of various types, which, by the way, predetermines the placement of the main controls( post 6).
7 - a motor that connects the control unit to the engine.
8 - angle reducer, which transmits the rotation of the shaft to the working spindle.
9 - cutting tool - special knife or coil( bobbin) with a cutting cord( fishing line).
10 - protective shield protecting the operator's leg from injury
The controls of the mower may differ somewhat in their layout, but usually include several keys and switches with the same functionality:
1 - switch( toggle switch) of the ignition circuit. Allows you to instantly muffle the engine if necessary.
2 - the main key that controls the throttle valve of the carburetor( the "gas" key).
3 - safety key, preventing accidental pressure on the "gas".While it is not recessed, it is impossible to use the main key.
4 - the control button lock is pressed. Facilitates the management of large amounts of work.
motokas. Typically, another control is located on the engine itself - the choke position switch. Used to facilitate the start and rapid warm-up of the engine in conditions of low air temperature.
A few more details on the main elements and nodes of the mower will be explained below when considering the parameters of the tool selection. For now, a few words about the advantages of gasoline trim tabs:
There are certain drawbacks to gasoline trim tabs:
Nevertheless, if it is expected to handle large areas of land, or work on the ground where there is no possibility to connect to the power supply, nothing better than a gasoline trimmer is not found. The advantages of such a tool significantly outweigh its shortcomings.
Before you start choosing the optimal model of a gasoline trimmer, you should very clearly outline the range of tasks that will be assigned to this tool. Proceeding from this, most of the evaluation criteria of choice will be predetermined.
All petrol braids are conventionally divided into three main groups.
Naturally, such tools are massive enough, have capacious fuel tanks. To facilitate work with them, special belt systems are provided to remove the load from the operator's hands as much as possible. In addition, special backpack models have been developed, that is, the power drive, which is worn by the employee in the form of a knapsack, is connected to the rod by a flexible transfer shaft in the casing. This arrangement is less likely to cause operator fatigue during prolonged operation.
Using a trimmer of this class in a personal environment looks redundant, the acquisition is unlikely to become profitable.
The power of their drive, the features of torque transmission, the availability of cutting attachments allow you to cope with vegetation almost no worse than the pro models. Farmer's scythes are used for care of a garden-garden, and for performance of profile agricultural works.
. They are distinguished by their low weight, high maneuverability, and ease of use. The power of their engine, it would seem, is low( usually within 1000 W), but it is quite enough for mowing grass and small shrubbery. The main cutting tool is the cord( fishing line), although some models may include knives.
The permissible duration of non-stop operation is low, and is usually limited to the capacity of a small fuel tank.
Two types of engines can be installed on gasoline braids - two-stroke and four-stroke. It should be noted immediately that this does not directly affect the power of the tool - there are also more professional motorcycles with a two-stroke drive, and small trimmers of the "amateur" class equipped with four-stroke ICE.
There are a lot of drawbacks.
- First of all, for filling motorcycle with a gasoline engine, you have to prepare a fuel mixture of gasoline A-92 and a special engine oil. The operation, in principle, is simple, but requires carefulness and strict observance of proportions. The prepared composition can not be stored for long - its properties are lost with time. That is, work with the trimmer will have to be preceded each time by preparing a fuel mixture.
- The second disadvantage is the large amount of exhaust, which is important if the work is carried out near residential buildings.
- And thirdly, such a tool is distinguished by its high noise level, which must be taken into account when using it, for example, in the early morning hours, in order to avoid misunderstandings with neighbors.
Such engines usually have a higher engine life, are capable of continuous operation without pauses, they use fuel much more economically.
Disadvantages of such ICE:
- The design is more complicated both for the device and for maintenance.
- Four-stroke engines are always heavier than peers with the same power of push-pull analogs.
- The main disadvantage, although somewhat arbitrary, can be called the high cost of gasoline trim tabs equipped with four-stroke engines.
The engine power can lie in the range from 700 ÷ 800 to 2500 or more watts. The choice directly depends on the expected load on the tool. In principle, it is power that predetermines the operational classification of gasoline trim tabs.
This parameter is sometimes indicated in the horsepower. The ratio is simple - 1 kW = 1.36 "horses", or, conversely, 1 horsepower = 0.74 kW.
Naturally, the increase in capacity is accompanied by an increase in the weight of the gasoline tank and its cost. So it is necessary to clearly represent the planned scope of the tool.
Rod The bar with the gear shaft located inside can differ in two ways.
. The curved bar makes the motorized motor more ergonomic - it is much more convenient to handle such difficult tools, for example, near trees, flower beds, benches, etc. In addition, the operator spends much less effort to maintain the cutting nozzle at a certain height. However, this is achieved by the fact that the rod has a flexible drive, which is always more vulnerable to loads, and the probability of its failure in an abnormal situation is much higher. This type of rods is more typical of small and medium-sized motor vehicles, not designed for heavy loads.
The demountable rod makes the tool more convenient in terms of transportation and storage. In addition, some petrol tank models assume the use of specialized working attachments - they are adapted specifically for the
demountable boom coupling. The drawback is clear - any excess drive connection is always an additional vulnerable place prone to wear. In addition, the operator is required to monitor the condition of this node, not to allow accidental land or sand entering it, to carry out maintenance, etc.
belt system To keep a bulky and heavy construction in a given position, controlling the movement of the cutting head parallel to the ground level is not an easy task. Therefore, it is extremely important to select a model for the convenience of its operation, and this directly depends on the configuration of the handles and the belts used.
Recommendations in this issue is difficult to give - every potential user in choosing a gasoline scoop must independently try on a tool for himself, assess the degree of convenience with him. In this case, of course, should also take into account the duration of the work.
. D-shaped or J-type handles are usually mounted on light motor scooters. They are more convenient to operate the tool when performing more "fine" maneuvering work. The control unit is located on the boom, shifted towards the engine.
All handles have a fastening system that allows you to move from along the rod, rotate about its axis, and in the case of a T- or J-shaped configuration - also change the departure value to the left or to the right. All this makes it possible to fine-tune the motokos under the operator's individual characteristics, to ensure its balance and to achieve maximum ergonomics.
If you expect a long work, especially - with a fairly heavy motorcycle professional or semi-professional class, it is better not to regret money for the purchase of a knapsack belt system. Such equipment will evenly distribute the load throughout the shoulder girdle and back of the worker, significantly reducing the level of fatigue. In addition, a special patch on the thigh of the operator will reduce the degree of transmitted vibration and protect against possible burns from the engine warming up during operation.
. For short gardening works with a light petrol trimmer, a normal shoulder strap with a soft wide top strip is also enough. The cost of such a belt, of course, many times less.
gasoline braid Work tools of the gasoline braid can be included in the kit or can be purchased separately.
The recommended diameter of the cutting cord is indicated in the parameters of the gasoline nozzle. Usually it is from 2 to 3 mm - quite enough for grass and thin shrubs.
toolboxes. Some cutters are designed specifically for mowing grass for harvesting purposes - unlike the same cord, they do not crush the grass, but provide a smooth cut.
Self-activity in the use of knives and milling cutters - is unacceptable. Manufacturers of gasoline pumps indicate the possibility of using a particular type of cutting tool. Neglecting the recommendations may cause the trimmer to malfunction.
So, on a gasoline braid with a collapsible rod, a brush cutter, a small chain saw for cutting off tree branches,snow, and even various cultivators for surface tillage.
The variety of models presented on the market can puzzle an unsophisticated buyer. What kind of gasoline pump should I prefer with equal performance?
Certainly, it is necessary to be guided by the manufacturer's reputation, the warranty period of the tool, provided by it, and the extent to which the network of servicing models of a particular brand is developed in the region of residence, to what specific technical support it will be possible to count in case of unforeseen breakdowns.
Husqvarna, Makita, Stihl, Oleo-MAC, ECHO are considered to be the leaders in the manufacture of such tools. Although these brands are worth a lot, they fully correspond to the quality standards. It deserves only positive assessments of the production technique of Hitachi, Patriot, Caiman, Huter, Hyundai. If you do not want to spend extra money just for the brand, then it's quite possible to purchase a high-quality and relatively inexpensive tool of Chinese brands or assemblies - Intertool, Rostech, Sadko. A good reputation is also earned by domestic gasoline braids, for example "Cedar" or "Izhmash".
In any case, purchase the tool only in specialized stores, where you can read the terms of the warranty and make a note of the date and place of purchase. Unfortunately, the market of instruments of this class is literally teeming with low-quality counterfeits, and the probability of buying such a "gift" in the spontaneous market or with hands that will quickly fail is extremely high.
