One of the most sought-after tools for the garden is the benzocosa. It is used in the fight against high grass on the lawn, the removal of thickets around the garden, cut the tops before digging root crops, harvesting hay for several animals. Often the sound of the mowers can be heard in the high-rise block when utilities are working. The type of equipment model also differs depending on the volume and terrain being performed, as well as the type of mowed vegetation. The material below will help you correctly select this garden equipment for specific tasks.

The best manufacturers of benzocos - which company to choose
If you need to urgently buy a reliable benzokosu and do not have time to study all its features, then you can refer to the products of trusted companies:
- Champion;
- Echo;
- Huter;
- Carver;
- Hitachi.
To make sure that this garden tool will cope with a specific task, you should read a review describing the suitability and possible difficulties for specific models of well-known brands. Well, to choose a fully independent benzokosu, solely on the parameters, can the one who read this article to the end.
The principle of operation and the device benzokosy
The gas mowers use energy from burning fuel to excite engine rotation and transfer torque to the cutting element, making it possible to mow green grass, dry shoots, stiff trunks and shrubs.
Significant difference from the lawn mower is easy transportation of the tool into place. Some collapsible models can be transported even on the trunk of a bicycle. Distinguishes motokosa and use on steep slopes. The operator can tilt the cutting head at different angles, achieving a good result without a negative impact on the equipment.
The low weight of the trimmer allows you to work for a long time and faster than pushing ahead the lawn mowers. If a stone or a thick branch gets under the cutting element, then the line of benzokosy will just hit the obstacle without consequences. Due to this, the device is successfully used for grass mowing next to the curb, pillars and fence.
Benzokosa consists of the following components and parts:
1. Internal combustion engine;
2. Boom;
3. Fastening for fishing line or knives;
4. Protective cover;
5. Handles with control buttons;
6. Thigh pad;
7. Fuel tank;
8. Starter to start;
9. Muffler;
10. Gearbox;
11. Belt mount.
Cutting grass occurs due to the rapid rotation of the shaft inside the rod, which is transmitted to the reel with fishing line. The latter has exposed ends. They then dissect the stems in a collision.
The line is convenient because it does not break when it comes into contact with stones, a fence or pillars. In this case, its abrasion is faster, which requires stopping the process and lengthening the ends, but it takes no more than a minute.
In addition to fishing line benzokosa able to cut knives and discs. They are made of plastic or metal and are more solid, which allows you to remove thick shrubs and stiffness from the territory. But before working with such a device, it is required to clear the space of stones and large branches.
The operator wears a benzokosu on one or two shoulders, using a fastening belt. Starts the tool with a wrench cable from the starter. Further control is carried out by handles, which can precisely coordinate the position of the cutting part.
At the beginning of the bevel, the operator pulls the gas trigger, adding revolutions to the knife.With a short transition from one area to another, the engine is not turned off, but only the gas trigger is released.
Types of benzokos
Household
They are distinguished by low engine power (up to 1.5 hp), thin fishing line, light weight and a collapsible rod, convenient for transportation. Most often equipped with a two-stroke engine and a D-shaped handle.
With their help, you can mow the grass in the country, around the garden, between trees in the garden, in flowerbeds, under the benches in the park. They are designed for short work during the day and small loads.
Advantages:
- a light weight;
- affordable price;
- a variety of connected knives;
- collapsible rod;
- simple operation;
- gasoline and oil poured into one hole.
Disadvantages:
- loud engine operation;
- more toxic exhaust;
- low power
Professional
Models are of high build quality. Rod most often straight. There is a wide choice in the form of the handle, convenient for various working conditions. Powertrains are powerful and quieter. Interact with fishing line, discs and knives for 3-8 petals.
Such a tool weighs more and does not understand, which is inconvenient for transportation, but is able to function for 6-8 hours every day. They are used for harvesting hay, cutting grass among high-rises, on the sides of the track, in large parks.
Advantages:
- powerful power units;
- robust construction;
- a variety of cutting elements;
- the ability to use many hours;
- quiet work;
- less toxic exhaust;
- minimum backlash.
Disadvantages:
- large mass;
- inconvenient transportation;
- complex care and repair;
- high price.
Options for the selection of benzokosy
Power
How quickly it will turn out to do the job with a benzokosa depends on its power. It is measured in hp and it can be from 0.7 to 3.2. The higher the power, the faster the cutting parts will rotate, which will speed up the passage through the area.
More power will play a role when the line encounters stiffness. Weak models will beat a solid obstacle and may cut it for the fifth time or miss it. Stronger machines mow a rough stalk the first time, so the cleanliness of the section after the passage also depends on the power.
1. If the motokosa is bought to take care of the garden in order to cut the grass between the trees or in a flower bed, then the indicators are rather low in 0.7-1 hp.
2. To work with coarser vegetation (courtyards of high-rise buildings, a vast territory of enterprises), values of 1.5–2 hp will be needed, which will allow to cope with hard stems and deadwood.
3. Mowing grass on the side of the road, where shrubs and a lot of stones meet, will require 2.1-3.2 hp.
Engine responsiveness
Benzokosy equipped with the following types of engines:
1. Two-stroke power units - have pistons to compress the mixture, and the inflow and outflow of air through the side and top openings in the chamber. Working in two cycles, the device simultaneously performs air intake and combustion together with gasoline vapors, as well as exhaust emissions.
These models require pouring fuel and synthetic oil in one hole. They work louder, and the emission is more toxic. But different unpretentious service and cheap repair. The cost is very affordable. This benzokosa suitable for cottages, utilities.
2. Four-stroke power units - work, as well as the power unit of the car. They present a system of air valves, which carries out air leaks and exhaust emissions in parallel with the movement of the crankshaft and the piston stroke. Such products are more expensive because they are more reliable and durable.
These mowers are suitable for professional activities in large areas (harvesting hay, mowing grass along the road for many kilometers, caring for the vast territory of a park or an enterprise). Gasoline and oil are poured into different openings, which gives less toxic exhaust and quiet operation.
Engine capacity
This is the second parameter that determines performance. Power units motokosa are with a volume of from 22 to 57 cm3.The higher the number, the faster the knives can rotate. This is due to the size of the engine cylinders.
In the volumetric model of the combustion chamber enters an increased amount of gasoline vapor and air, the compression of which leads to the release of more energy and faster torque.
1. For beveling soft grass in the country, flowerbed, lawn for children behind the house, rather low figures of 22-25 cm3.
2. To care for the park and cut the grass between the trees, under the benches, next to the paths, you need a device with an engine capacity of 30-40 cm3.
3. Rough shrubs and dense vegetation need professional equipment with an index of 45-57 cm3.
Type of cutting element
1. Fishing line - is the cheapest means of mowing. Rapid rotation provides a cut of green grass and thin deadwood. This is a good option for cottages, utilities and park workers, because the fishing line will not deteriorate when colliding with a pole or border. But for very thick grass, it will not work, because it quickly becomes entangled in it.
2. A plastic knife is similar in properties to a fishing line, but its resource is much longer due to its denser structure. In contact with solid obstacles the knife does not break. This is a more advanced option for the care of roadsides and mowing grass on the slopes.
3. Metal disc - has a lot of teeth and works like a saw. He is able to eliminate not only grass and deadwood, but also shrubs several centimeters thick. Perfect for mowing thick grass on flat terrain, despite the existing thickets of stiff trunks. But on the slopes can be loaded into the ground, which slows down the work. At hit on a stone small crumbs take off, therefore demands wearing of glasses.
Line thickness
When a fishing line is used, its correct thickness is important. The selection range varies from 1.4 to 3.3 mm. In contact with thickened stems, deadwood or shrubs, too thin element will not be able to cut through it and leave it whole.
The thicker the line, the better it will be to cope with obstacles. There is also a different form of fishing line, corresponding to the work ahead. The traditional round shape is considered. Specialized are square and hexagonal.
1. For work in the garden, where the soft grass, enough cutting element with a diameter of 1.4 mm with a circular cross section.
2. The courtyard territory of multi-storey buildings or the edge of a vegetable garden in a village will require a 2.7 mm indicator with a square section.
3. Overgrown along the road with an abundance of rough trunks need a diameter of 3.0-3.3 mm with a hexagonal cross-section.
Cutting width
Motokos are able to mow in a single pass a different width from 225 to 460 mm. This is the third performance indicator. To cut the grass on an area of 2x2 m with a device with a minimum parameter you will need to perform 8 sweeps, and a maximum of 5. But more, does not always mean better.
1. If benzokosa is needed to care for narrow areas of grass in a park, flower bed, then a large width of the cut will not affect performance, because the number of moves will be the same. Values of 225-300 mm are allowed here.
2. Large width indicators are needed on spacious fields where hay is harvested or in large areas of enterprises, sanatoriums. It uses 350 mm or more in width.
Tank capacity
The capacity of the barrel for fuel is from 0.3 to 1.2 liters. The larger the volume, the longer the unit will be able to function without refueling. With small indicators and a large distance from the location of the fuel, an additional canister with you is needed. This should be taken into account when working remotely from the location.
1. In the country, where you can always go into the house and pour fuel, you can use the smallest figures of 0.3 liters.
2. Employees of parks and utilities will have enough 0.5-0.7 liter tank to work for a long time and periodically return to the base to replenish stocks.
3. To work in the field (harvesting hay) or on the side of the road, we need models with a 1.2 liter tank.
Pen type
There are several common types of pens:
1. D - allows you to firmly hold the device when jerking, which is practical to work with a disk on an area with stones and branches;
2. J - more convenient on steep slopes, because it gives a natural slope for the cutting element;
3. U and the bike option allow you to easily maneuver the head, which is useful when avoiding obstacles (pole, garden statue, pipes) in flowerbeds and mowing grass in narrow areas.
Drive shaft
This element is of two types:
1. Hard shaft - transmits torque from the power unit to the spindle gearbox via a straight steel shaft. This is a more robust design that can withstand collisions with coarse vegetation. Such trimmers get to clean running sites and professional activities. Hard drive interacts well with knives and discs.
2. Flexible shaft - transmits rotation through a cable inside the rod. Its plus is that when a knife collides with a stone, vibration is partially absorbed by the cable, and less falls on the engine. But because of the less rigid structure, the power and the ability to cut off thick elements is lost. Therefore, such models are suitable for giving and soft grass.
Weight
Mass benzokosy can be from 3.8 to 10.7 kg. It depends on the engine equipment, fuel tank size and drive shaft type. Often the more powerful the device, the heavier it is. But weight must also be considered for ease of use by the operator.
1. For long work in the park, a huge garden or the territory of the enterprise, it is better to purchase models weighing 4-6 kg, from which the shoulder does not get very tired. This will allow you to work half a day without long stops.
2. Employees of public services for mowing the grass on the blocks and along the road will need more powerful models weighing 7-10 kg, but the process will require interruptions.
Collapsible shaft
In some models of trimmers, the boom on which the power unit and the cutting element are located at the opposite end can be disassembled into two parts. This allows equipment to be placed in the trunk of a car or tied to a bicycle frame.
This design is convenient for transportation from place to place and compact storage in the pantry. It should be purchased to give or treat small areas in parks, flower beds, especially if one employee often has to move through different objects.
Devices with a non-separable shaft are more robust and suitable for continuous use, but are problematic during transportation. It is reasonable to buy them for operation in one large area or in the presence of transport for transportation.
What benzokosu choose
1. Take care of the yard in the country or a small garden will turn out with a trimmer with a capacity of 0.7 hp, two-stroke power unit, 21 cm3 in volume, with a 1.4 mm fishing line, 225-250 mm cutting width, 0.3 liter tank capacity, flexible driving shaft and with a gross weight of 4 kg.
