How To Repair A Lawn Mower

How to choose a lawn mower Which lawn mower to choose, how to work correctly

Types of lawn mowers

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

  • Professional
  • Household

Professional lawn mower 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, the lawn mower 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 lawn mower 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 lawn mowers are used for mowing dense thickets and bushes.

Household lawn mowers 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 lawn mower 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 mower 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 lawn mower 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 lawn mower 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 lawn mower can perfectly cope with such a volume of work.

How to choose a lawn mower

Lawn mower or a gasoline trimmer is a convenient, mobile, practical and therefore a very popular tool with which you can mow grass, stiff shoots, small bushes in your summer cottage, near your house, in the garden before harvesting potatoes. Recent times lawn mowers 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 from the consumer: which one to choose for a lawn mower in a 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 lawn mowers are, for what types of work they are suitable, as well as the basic rules for operating a gasoline trimmer.

We work as a lawn mower: basic rules

The main requirements for working with a lawn mower 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 lawnmower work at 50% of its capacity on one tank of such a mixture, then feel free to fill in the usual mixture. When preparing a fuel mixture for your lawn mower, 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 lawn mowers 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, which 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 tools without the protective shield that comes with every lawn mower
  • 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.

How to choose a lawn mower

The gasoline scythe, which makes a pretty decent noise and hums, and also releases a cloud of caustic gray smoke, is the one with a gasoline 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.

What engines does Hyundai use for its lawn mowers?

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. For generators one, for snow blowers completely different, winter, for cultivators and tillers the third. 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 lawn mowers.

Hyundai lawn mower motors 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.

The lineup which lawn mower and where is more practical to use

Before choosing a lawn mower 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 lawn mowers 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 lawn mowers 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.

Installation and adjustment of the petrol trimmer mount. Backpack strap.

Ease of use depends not only on the correct placement of the gasoline trimmer on the backpack strap, its balance, but also on the correct installation and adjustment of the two-handed handle, often referred to as bicycle.

How to adjust lawn mowers mountings. Knapsack belt

From correctness lawn mowers mounts the comfort of the gardener and, as a consequence, the speed and duration of his work depends on the backpack strap. Many people do not want to spend time adjusting the petrol trimmer mounts on a two-shoulder strap, and perhaps this is justified if it is necessary to cut the grass only in a small area or near a fence, but in large areas, the issue of convenience and endurance will become paramount if we do not want to stretch the mowing for several days In addition, a properly adjusted lawn mower mount will make mowing much safer. As for me, it is worthwhile to understand this issue.

Adjusting the lawn mowers attachment. What to strive for.

Once the two-handed handle and backpack-style belt have been adjusted, the cutter of the lawn mower hanging on the harness should be parallel to the ground, without your hands touching the garden tool. The height, of course, can vary depending on the task being performed, 20-30 centimeters for mowing tall grass for forage, 5-10 centimeters for mowing lawn grass.

The mower must be balanced with the cutting tool installed: disc or line spool.

Top quality lawn mowers and electric mowers tested by millions of users

The ergonomics of the devices deserve special attention. Users especially note the following elements of the lawn mower, which ensure ease of use:

  • Comfortable grip to prevent operator hand fatigue;
  • Comfortable shoulder strap equipped with an anti-vibration system;
  • Convenient collapsible mechanisms that allow you to prepare for work without additional tools.
