How to choose a brushcutter What kind of brushcutter to choose, how to work correctly

How to choose a brushcutter

Motokosa or a gasoline trimmer is a convenient, mobile, practical and therefore very popular tool with which you can mow grass, stiff shoots, thickets of small bushes in your summer cottage, near your house, in the garden before harvesting potatoes. Recent times brushcutters became very popular in agriculture for harvesting hay. However, a large selection of models with different technical indicators and a wide range of prices raise a natural question for the consumer: which brushcutter to choose in terms of price-quality ratio, and so that its technical characteristics meet the tasks that will be performed as much as possible. In this article, we will try to tell you what brushcutters are, for what types of work they are suitable, as well as the basic rules for operating a gasoline trimmer.

Types of brushcutters

Depending on the technical characteristics, as well as on the operating mode, all brushcutters can be conditionally divided into:

  • Professional
  • Household

Professional brushcutter designed for industrial use, performing a large amount of work for a long time, and is perfect for use by utilities or in agriculture. Naturally, for this brushcutter must have not only high technical performance, but also the appropriate build quality. As a rule, professional models have engine power from 1.8 hp. And above, they are equipped with both a trimmer head with a line and a steel knife. Over, the thickness of the fishing line is greater than usual (from 2.4 mm), and the knife can be 3, 4 and 8 lozenges (the latter is used for mowing tall, weaving grass and for hay harvesting). There are also knives with a large number of teeth, they visually resemble saw blades and are used for mowing bushes. In addition, a distinctive feature of a professional brushcutter is a non-separable bar, in the middle of which the shaft moves. On the one hand, this is not very convenient, especially when transporting and storing the tool, since the device is quite large, and on the other hand, such a design prevents sand, dirt, dust from getting into the middle, which significantly extends its resource. Over, the connecting mechanism of the two shaft parts may loosen over time, which causes backlash. Separately, it is necessary to dwell on the shaft, which is located in the middle of the rod and transfers the engine torque to the cutting attachment. It comes in two types: flexible and rigid. The flexible shaft has the appearance of a cable and prevents damage to the gearbox when a knife strikes from a stone or tree trunk. It simply absorbs this blow. At the same time, the rigid shaft (metal pin) resists deformation under load. These brushcutters are used for mowing dense thickets and bushes.

Household brushcutters intended for work near the house, in the garden, in the garden. They rarely exceed 2 HP and can also be fitted with a line trimmer and steel blade. Structurally, they are similar to professional models, but there are some features:

  • A number of household models are equipped with a curved bar, which is convenient when working in hard-to-reach places (under benches in the garden, near flower beds, between trees), since such brushcutter less overall than its counterpart with a straight bar;
  • A type of handle, which can be bicycle type (like professional models), or it can be D-shaped. In the second case, a handle is attached to the brushcutter bar, which the user holds with one hand, and the other hand holds the tool by the bar near the engine. Users’ opinions were divided: which design is more convenient. The matter, as they say, is a matter of habits, since it will change from a bicycle handle to a D-shaped one or vice versa, as practice shows, not everyone succeeds
  • Household models are more often found with a collapsible bar, which is very convenient for storage and transportation, since disassembled brushcutter two times less, and assembling it back is not difficult and takes a minimum of time.

Another feature that significantly distinguishes a household model from a professional one is its cost. The latter will be much more expensive. Therefore, before choose a brushcutter it is necessary to decide which tasks you will perform with its help. If you have a plot of up to 15-20 acres, it is absolutely not necessary to overpay and buy a professional tool, since in this case a household brushcutter can perfectly cope with such a volume of work.

We work with a brushcutter: basic rules

The basic requirements that are put forward for working with a brushcutter directly depend on the rules for operating a gasoline 2-stroke engine. Such a motor runs on a fuel mixture of gasoline and 2-stroke oil, which is prepared in a ratio of 1:50, that is, 1 gram of oil is added to 50 grams of gasoline. It should be said that when starting work with a new tool, it is recommended to add a little more oil. Let the brushcutter on one tank of such a mixture work at 50% of its power, then feel free to fill in the usual mixture. When preparing the fuel mixture for your brushcutter, remember that it is suitable for use for no more than two weeks, after which its properties change, which negatively affects the operation of the tool as a whole. Therefore, do not rush to prepare it in large quantities, and also drain the fuel from the tool during long breaks between mowing. There are also models with 4-stroke engines, in which oil is poured separately with gasoline, they are more economical and have a longer service life. But such brushcutters have more weight and cost more.

Before starting work, we recommend that you carefully inspect the area and remove stones, branches, and other debris from it that you may not notice in the grass during work, which can lead to breakage or to premature wear of the cutting tool. When working with a gasoline trimmer, you must remember that it is not only a practical and convenient tool, but also quite dangerous. Since the trimmer head with line or steel blade turns at a high speed, the following safety rules must be observed when working:

  • Do not use the tool without the protective shield that comes with each brushcutter
  • Wear glasses when working to prevent grass particles from getting into your eyes
  • The engine heats up during operation, therefore, when removing the tool between mowing, it is better to hold it by the bar or the handle.

Why is a noisy and heavy gasoline scythe better than a light electric one?

The brushcutter consists of a gasoline engine, cutting equipment, controls and a transmission shaft. This whole structure has long been thought over, analyzed, improved and perfectly balanced. For ease of use, the tool (relatively heavy in weight) is equipped with shoulder straps or a convenient backpack attachment. That is, the weight of the device lies evenly on the arms, shoulders and back, and you don’t feel fatigue in your hands.

The electric trimmer has a similar design. Over, it is lighter and more convenient to work with. So for mowing a small lawn near the house, a small adjoining lawn, caring for the garden adjacent to the house, it is better not to find a tool. However, please note which terms we use: small, close. That is, there are two conditions:

  1. The plot should be small (up to 5 acres);
  2. Placed near the house, that is, an electrical outlet.

If your mowing tasks do not meet these two criteria, then the choice of a brushcutter is tipped in favor of a gasoline engine. Is he:

  • Works anywhere, anywhere and anytime, since it is not tied to the electrical network;
  • The size of the plot is practically unlimited (except for the power of the motor, the more powerful, the more area you can take for mowing);
  • Power and performance are always higher than that of an electric trimmer. This means that the quality of cutting will be better, and the efficiency is the same for soft grass, and for hard weeds, for tall thickets;
  • The previous item brings with it the next opportunity to change the equipment. Not only a wire line, but also a three-pronged knife or even a multi-pronged disc for cutting and sawing hard growth;
  • Increased resource, reliability and the ability to withstand heavy loads. This is a property of a gasoline engine. Electric cannot boast of such characteristics;
  • Well, let’s not forget about the structural elements. The steel rigid transmission shaft (with high efficiency), the most comfortable bicycle handles are all the prerogative of gasoline braids. Their electric sisters have a flexible shaft (with a cable that bursts under load) and a D-shaped handle (for one-handed grip). But there are models that completely copy brushcutters. With direct drive, gearbox and steel shaft.

In fact, these are the main criteria when you are dealing with the question: How to choose a brushcutter? Yes, one that mows, and does not stand idle in the barn.

Model range which brushcutter and where is it more practical to use

Before choosing a brushcutter among the many petrol models from Hyundai, first determine:

  1. Land area;
  2. Vegetation on it.

Soft and juicy grass on a flat lawn does not require a knife, only fishing line. For this, the Z 250 braid is presented in the model range from Hyundai. It is slightly different from other Hyundai braids with a gasoline engine. Its design is more like an electric scythe. Its shaft is flexible and the handle has a D-shaped grip. In fact, it is a lightweight petrol trimmer. Mows only with wire (line). If you put the knife down, the cable will not support the load. But for turf, this model is ideal: easy to mow, carry and store.

All other Hyundai braids have steel shafts, which allows you to use any attachments for mowing: a knife or a disc. And this means that we not only cut the grass, but also chop weeds, cut undergrowth of bushes and even thin tree trunks.

With regard to the size of the site, the situation is as follows:

The larger the area, the higher the engine power should be. For example, the lightweight and comfortable brushcutters Z 250 and Z 260 are good for small areas, they have power. 1.2 h.P. They will not pull a large meadow for 20-30 acres, for this, choose the models Z 420, Z 525, they have a power of 1.6 hp. And even 2.04 hp. The most powerful.

So, focusing on the area and vegetation:

  • If the task is to mow only lawn grass (including high and wet), and a lawn for 5-10 acres, then your choice. Models Z 250 and Z 260;
  • If you need to mow everything in a row on a plot of 10 acres (weeds, unnecessary shrubs and young shoots of trees that have grown without permission), then choose among the powerful brushcutters Z 340, Z 420;
  • For professional work on large areas (20-30 acres), where you need to work with vegetation of different hardness and rigidity, focus on the most powerful representatives of the Hyundai lineup. Z 420 and Z 525.

What engines does Hyundai use for its brushcutters?

The Hyundai company differs from competitors in that it creates its own gasoline engines, and not standard and of the same type, but very, very diverse. There are some for generators, for snow blowers they are completely different, winter ones, for cultivators and motoblocks there are still others. Each group of Hyundai Genuine Engines owns its own design features and is ideal for the exact tool for which it is designed. So it is with brushcutters.

Engines for Hyundai brushcutters are two-stroke, run on a mixture of gasoline and oil.

  • The cylinder is covered with nikasil, which improves heat transfer;
  • Compression at start-up reduced easy start system;
  • The Japanese sintered metal gearbox is almost always work, as well as noise and vibration reduction. This is a powerful argument for those who dislike the howling and shaking instrument. In addition to the gearbox, there is also a whole system for reducing vibrations, so that these braids do not shake with the hands, there will be no pain in the hands and joints;
  • They are easy to start and operate at low temperatures, they are not afraid of moisture and tall grass.

How to choose a brushcutter

The petrol scythe, which makes a pretty decent noise and buzz, and also emits a cloud of acrid gray smoke, is the one with a petrol engine. For the uninitiated, a reasonable question arises: Why complicate your life? Wouldn’t it be better to use a quiet electric trimmer and not take on the hassle of a petrol engine? Over, Hyundai is a very popular manufacturer of garden tools in Ukraine, it produces both braids. Both with an electric motor and a gasoline one. At the same time, electric trimmers are cheaper and do not require refueling.

The answer is simple. A gasoline engine, even noisy and very demanding, always has undeniable advantages over an electric one.

Outcome

So, you have already realized that the adage Much Ado About Nothing. It’s not about Hyundai brushcutters. The louder they are, the heavier the weight, the higher the mowing performance. As well as quality and efficiency, reliability and durability. And also a unique opportunity to mow grass not only on the house lawn, but also on vast territories, in the forest, in the field in general, in any place where there is a need and opportunity to prepare grass mass.

To select the required brushcutter, we determine the size of the site (for a small one, low-power models, for a large one, it is more powerful). We also look at the growth: for grass, a light gasoline trimmer with a fishing line is enough, and for weeds and tough vegetation, we choose the Hyundai model with a steel shaft, in which you can change the fishing line to a knife.

How does the starter for petrol cutters or trimmers work?

The starter mechanism is generally a single and universal mechanism for petrol cutters, trimmers, gasoline and diesel generator sets. It is not a problem to equip them even with a car, motorcycle or scooter, if your vehicle has free space for its installation. It was not for nothing that many Soviet cars and trucks were equipped with a starter tool that remotely resembles a crowbar bent twice.

The starter assembly has the following parts:

  • Hook ignition spring;
  • Cord wound on a reel;
  • Return spring;
  • Ratchet drive and main spring;
  • Mechanism housing protecting the ratchet;
  • Locking bolt.

How tight is the spring cocking?

It is possible to give the spring the necessary potential force required for a clear and fast winding of the cord by determining the length of the cord in turns. To prevent the cord handle from drooping, add 1-2 more turns to the number of turns. So, if the cord has a length of 5 turns of the coil, then, when charging the spring, turn the coil 6-7 full turns.

How do I replace or replace the starter spring?

If everything is in order with the rope on the starter, suspicion falls on the reel itself. It is activated by a ribbon spring, coiled into a roll. Certain steps must be taken to change the spring.

  1. Remove the starter from the brushcutter.
  2. Remove the starter coil.
  3. Unscrew the main bolt holding the pulley to the housing.
  4. Pull out the gripping tendrils and spring, the ribbon spring is almost fully extended or coiled into larger rings.
  5. Hold it in advance.
  6. Check if the spring is intact (there may be rusty streaks, cracks, etc.). If the hooks at its ends are broken, bending new ones will fail. High carbon steel breaks when you try to bend it. Loose hooks are suitable for slight bending.
  7. Make sure the auxiliary (regular) spring and washers are in place. These parts protect the coil body from being punctured by the ends of the main spring. If the washers and the spring are broken, and new ones are not available, do not tighten the coil bolt tightly, but watch it, it can unscrew and get lost.
  8. If the main (flat) spring is damaged, insert the same new one. Place the hook on the end of the spring in place and bend it, inserting coil by coil into the space it should be.

The rewinding of the spring takes a minute. Dexterity in this action is acquired quickly.

How to replace or replace the starter spring, see the following.

Assembling a brushcutter starter

When servicing and repairing the starter, it is important to properly assemble it as if the assembly was carried out by the manufacturer. Any part that is incorrectly installed will prevent you from fully using the trimmer or brushcutter.

  1. After winding the spring, turn the coil over and position it so that the second spring hook falls back into place. To control the correct installation of the spring, there are technological windows on the coil itself.
  2. Install the starter pulley and make sure one of the spring hooks fits into the groove located on the starter cover.
  3. Insert the spring and washers on the sides to prevent the spring from rubbing off the plastic compartment in which it is located. If the spring is broken, and the other is not the same, an additional washer is placed in its place.
  4. Insert the antennae cup into the grooves on the spool.
  5. Install the coil in its place, tighten the bolt as far as it will go, but without fanaticism.

If you do not protect the compartment from the main spring with washers, where it moves when winding and unwinding the starter cord, the coil often sticks when you try to start the petrol trimmer or brushcutter. Loosening the coil bolt will result in its loss.

  7. How do I change the starter cord?

The recoil starter for a petrol cutter or petrol trimmer is a mechanical unit that includes a pulley fitted to a ratchet. A rope is wound on the pulley in the initial position. At the start, it is pulled outward. The pulley is spring loaded as soon as you let go of the end of the rope, as it reels back. A flat strip rolled into a ring is used as a spring. It resembles a spring in a large mechanical watch that is wound once a day. The starter itself is located more often at the rear than closer to the front end of the mower or trimmer. In order to correctly perform all the manipulations with the petrol cutter starter, you need to know the features of the device and installation.

How to assemble a new mower starter?

For starter assembly do the following manipulations.

  1. Pass one end of the cord through the opening at the beginning of the spool and tie it in a knot. The knot must not pass through the hole. Otherwise, you will disassemble the starter again.
  2. Wind the cord around the spool itself.
  3. Install the spring into the starter housing, hook one end of it in the groove and wind it. For convenient winding, twist the body counterclockwise.
  4. Place the ratchet on the spring.
  5. Hook the return spring to the ratchet itself, secure it to the spool.
  6. Install the main spring and housing with the assembled ratchet, connect the starter parts together and tighten with the main bolt.

After assembling the starter, pass the free end of the cord through the hole in the housing for the reel. Pass this end again through the hole in the handle that the cord is pulling on. Tie a strong knot on the handle. Check the operation of the starter handbrake.
