How to choose a gasoline trimmer

Any garden or country site requires systematic maintenance of order: mowing excess vegetation, trimming the lawn, cutting down unwanted bushes and eliminating weeds. If this is not done, the entire area will be overgrown with weeds and displace garden crops. The lawnmower, or gasoline trimmer, can do the trick. They are more convenient than electric models, as they are energy-independent and mobile, as well as have higher power.

Today there are many models of gasoline trimmers designed for different types of work. They can differ in type and capacity of the engine, boom design, types of cutting equipment, handles, and have different devices for hanging the unit on the back. Our article will help you learn how to choose the right gasoline trimmer for your area: it will be convenient for work and mow not only grass but also hard weeds and young bushes.

Benzotrimmer: which engine to choose

Gasoline-powered trimmers usually use a two- or four-stroke engine. Each type has its advantages and disadvantages.

  • Use pure gasoline as fuel
  • Service life is longer than that of a two-stroke
  • Economical use of gasoline
  • Low noise and vibration level
  • Infrequent oil changes (after every 50 engine hours)

In addition to the basic varieties, there are 4-stroke models in which oil is not filled separately, and mixed with gasoline (fuel mixture), but the cost of such benzotrimmer will be rather high.

A choice of accessories

In the question of how to choose a gasoline trimmer by price and quality and buy a model suitable for all parameters, the cutting equipment is of no small importance. No matter how powerful the engine of a gasoline-powered trimmer is, a fishing line will not be enough to cut down young bushes and plants with thick stems. And if soft grass prevails on your site and there are a lot of trees or flowerbeds around, it does not make sense to buy a metal blade. even with dense vegetation the cord will cope with, and mowing the grass around objects can simply damage them and blunt the teeth of the saw equipment.

Nylon or coaxial fishing line in various diameters and cross-sectional areas. It can be used for mowing soft and hard grass of different densities. Not suitable for making hay, as it tears the blade of grass into small pieces.

The grass trimmer cord is differentiated by its cross sectional shape.

  • Champion C7006

Line is a consumable fabric, so you need a new coil over and over again. Choose the right type of line not only by cross-sectional area but also by diameter. Let’s look at a few popular brands of trimmer line.

  • Champion is a fairly young brand that offers in-house manufactured cutting tools. Depending on the intensity of the load, all fishing line is divided by color:
  • Yellow for short work (Round Series and Star Series),
  • Red for heavy use (Square Twist DUO. twisted square and Star Pro. star).

All accessories of this brand are of high quality.

  • OREGON. one of the leading producers of cutting equipment for gardening equipment. Like Champion, OREGON is also available in different colors and shapes.
  • OREGON Starline. in yellow with a star shape,
  • ROUNDLINE. the round yellow or red one for all work on the plot,
  • Nylium. square section, the line itself is made of nylon monofilament,
  • BIOTRIM is a biodegradable line with a circular cross-section.
  • DUOLINE. gray, coaxial (two-layer: the upper layer is soft, the inner layer is rigid), used for very rigid vegetation.

OREGON line is sold in different spools: for occasional domestic use. coils up to 100 m, for professional use. spools up to 500 m.

  • Husqvarna, one of the world’s most popular gardening equipment brands, also produces accessories for trimmers. All fishing lines of this brand are categorized by color according to their diameter.
  • Green. diameter up to 2 mm,
  • Yellow. up to 2,7 mm,
  • Red. up to 3 mm.

This division makes it easy to find the right size for the job. Husqvarna line is available in round and coiled sections and in small coils and large reels of 50-240 m. There is also a separate series of Whisper and Whisper X cord. the products are highly wear-resistant, because the ends do not break when working (e.g. Husqvarna WHISPER 2.4-15(red) 5784359-01).

In addition to these brands, other brands in demand include PATRIOT, Sturm, Caiman, and others.

Cutting knife

Metal cutting blade or circular saw blade can also be used for cutting dense grass (the stems can get wound up on the fishing line and spool and must be periodically cleaned) and making hay, but their main purpose is to cut bushes, plants with stiff stems and to cut thin trees and branches.

  • Plastic. perfectly copes with dead wood and hard stems,
  • Metal. useful for cutting green, dense vegetation. Made, as a rule. Made of tool steel, hardened ones are more durable, but they are more expensive.

Number of teeth depends on how dense the vegetation and the complexity of the terrain. Knives with 3 or 4 blades are good for hard cases, but for hay-making it is better to take a 1 or 2-blade knife, because it keeps the stalks intact and does not cut them into several pieces.

Gasoline trimmers may have only mowing head with a line or knife, or may have all at once. These models are more versatile and are great if you have mixed vegetation on your property. E.g. PATRIOT PT 5555ES Country, Echo SRM-2305SI, Oleo-Mac SPARTA 25 ECO ALUMINIUM.

Boom Varieties

The boom is the most important part of a petrol thrimmer. it connects the engine and the cutting attachment, inside the boom there is a shaft which delivers torque to the blade or the mowing head with the fishing line. There are two kinds of shafts: straight and flexible. Its shape influences the type of boom. it can be straight or curved.

  • Curved booms are usually put on small and medium power grass trimmers to mow soft grass, weeds and work the area with differences in height and in hard to reach places: along the fence, around trees, flower beds and benches. For example, Husqvarna 122 C, STIHL FS-45.
  • Straight handy for working at high speeds and cutting tough vegetation, bushes. robust and reliable than a curved one. For example, PATRIOT PT 3355, Husqvarna 128 R.

Choosing the shape of handle

How to choose a great handle for your country house petrol trimmer? Deciding on the right option. Handles have to fit comfortably in your palms and feel secure, even when working intensively.

  • Bicycle handle (or T-handle). Its shape imitates the precise movement of a regular lawnmower, making it perfect for big, tough jobs. The throttle lever is located on one of the handles. Its only disadvantage: in small spaces or hard-to-reach places it can be inconvenient because of its size (the handle protrudes on the sides). PATRIOT PT 4355 Imperial, Bigmaster BT152, Caiman WX24 Promo have such a handle.
  • D- and J-handle. As a rule, this type is put on benzotrimmer household and semi-professional class, such as STIHL FS-45, Echo GT-22GES, PARTNER XS 9667111-01. They are compact, have a rubber pad against slipping of hands, but it will not be very convenient to mow large areas or very dense vegetation with such a handle.

Lighten the load on your hands

Any model of a petrol trimmer is necessarily equipped with a shoulder strap or a backpack-type device. This takes the bulk of the load off your hands when mowing, because gasoline models have the heaviest weight of all varieties of trimmers due to the volumetric internal combustion engine and fuel tank.

  • A shoulder strap is a textile strap that is simply thrown over the shoulder. There is a carabiner at the end, to which the unit is attached. This is available on all home-standard models and lightweight trimmers such as the BIG-M BC233BM,
  • Backpack type belt (parachute belt, backpack belt, backpack harness) is a textile construction with padded shoulder straps, buckles and additional thigh protection. The grass trimmer can be easily hung on a carabiner hook. Such a device evenly distributes the load on your shoulders and back and is used with powerful professional trimmers with heavy weights, for example, Husqvarna 133R, Husqvarna 327 RDX. The design can be adjusted to any height and shape.

If you are not satisfied with the belt harness, which comes in the basic set with a gasoline trimmer, you can pick up another, more convenient. As a rule, all belts have a standard carabiner attachment, to which you can easily attach the machine by the special hole.

The device gasoline trimmer for grass

The basis of gasoline grass trimmer is the boom, which houses the cutting unit, engine and controls the tool. Special straps distribute the load on the operator during operation.

Engine

Gasoline grass trimmers are most often equipped with two-stroke motors, but there are models with a four-stroke engine.

Every internal combustion engine has a duty cycle. a series of processes that result in a portion of force acting on the crankshaft. Working cycle is:

Expansion of gases and their escape from the cylinder

Takt is the movement of the piston in one direction (up or down). If an engine completes a work cycle in two strokes (one shaft revolution), it is called a two-stroke engine, if in four. four-stroke. Fuel motors can run on gasoline or diesel fuel, but garden trimmers use only gasoline motors.

Two-stroke engines are relatively simple, weigh less and are not afraid of low temperatures. They are cheaper than four-stroke motors, that’s why they are so popular. At the same time, two-stroke motors are noisier and produce more harmful emissions, so they are almost unusable for greenhouses and hothouses.

For two-stroke engines, it is necessary to prepare a special fuel mixture of gasoline and 2T engine oil. The manual usually recommends using gasoline with an octane rating over 89, but the best option would be fresh unleaded AI-92. Gasoline with a higher octane rating (95 and 98) contains additives that can be detrimental to the engine piston system, leading to overheating and damage.

Each manufacturer has its own recommendations on what proportions to create a fuel mixture and what components to use. It is not suitable for conventional motor oil, because it is designed for water-cooled engines. 2T oil is just right for air-cooled engines. Some major brands also produce special oils for their own engines.

Four-stroke engines on gasoline trimmers are much less common, due to the fact that they are heavier and more expensive than two-stroke engines. But it is quieter, more economical and produces fewer harmful emissions. For the four-stroke motor there is no need to prepare a fuel mixture, because the mechanism runs on pure gasoline. Oil is also used, but it is not mixed with fuel, poured into a separate container, does not burn, and serves only for the correct operation of the engine.

Cutting equipment

Petrol-powered trimmers use a line (filament) or cutting blades and discs.

A filament reel can be installed on any grass trimmer. The recommended line diameter is always stated in the manual. Cord is good for mowing around trees, fences, walls and other buildings. the fishing line is good for thickets of grass, whose stems are not too thick.

filament feeding system can be semi-automatic or automatic. Semi-automatic is more common: on the bottom of the spool there is a button, pressing which adjusts the length of the protruding ends of the line. Automatic system is supposed to feed every time the motor is turned on.

Almost all gasoline grass trimmers come equipped with blades and cutting discs. The only exceptions are some models with low power (up to 700 watts).

Blades are available in metal or plastic. This tool is perfect for cutting bulrushes, phragmites, thorny grass with thick stems and for trimming bushes, but it is not a universal tool. The blade should not be used where there is debris or where stones or metal parts hidden in the grass can be caught. The risk of damaging the gearbox is greatly increased in this case. Mowing in hard-to-reach places near trees, fences, walls and greenhouses is much easier and safer than mowing with a fishing line.

Boom

The boom can be straight or curved, have a collapsible or monolithic design. Telescopic chainsaws are not used in gasoline mowers.

Grass trimmers with a curved boom are somewhat more convenient to handle, but the rotation from the engine to the gearbox in them is transmitted by a flexible cable. A system like this is not well suited to high loads and is not very durable. Models with a straight boom, where the torque is transmitted by a rigid transmission shaft, are better suited for intensive use.

Grass trimmers with a collapsible shaft are easier to store and transport in the truck, but this design is less common because it does not always guarantee a high safety margin. The monolithic boom models are better able to support heavy loads and are more durable.

Gearbox

Gearbox is a module consisting of two bevel gears that transmit rotation from the motor to the cutting attachment. Gears require periodic lubrication. Moving parts break down much more quickly without lubrication. A hole for lubrication is located above the rotary nozzle assembly.

Shroud

The cutting attachment of the grass trimmer is always protected by the blade guard (skirt). The cover protects the operator by preventing debris and small rocks from flying around. The hood usually has a cutter. a sharp knife that removes excess line length.

Belts

Since gasoline grass trimmers rarely weigh less than 4 pounds, special straps with fasteners and clasps help distribute the load. Belts can be shoulder or backpack type. Shovel-type distributes the load more efficiently and is considered the preferred option.

How to choose and what to pay attention to?

To buy the most suitable trimmer for the grass, it is enough to evaluate the main parameters that affect its operation and usability

  • performance. determined by the power, which ranges from 0.25 to 2.5 kW;
  • type of power supply. gasoline devices are not tied to a power source, electric ones work from a cable or battery;
  • type of cutting element. models are equipped with a fishing line with a diameter of 1-3.5 mm, a metal blade, disc or plastic knives;
  • weight. it varies from 2 to 9 kg, it determines the vibration of the device and the comfort in use for a long time.
