how to disassemble a lawn mower

To spend less time and effort mowing grass in the area, you need to use the mechanisms designed for this lawn mowers, trimmers and lawn mowers. With their help, it will be possible to maintain the area adjacent to the house in excellent condition. The advantage of lawn mowers is that it is not tied to a power source like electric scythes. In addition, its application allows mowing grass on uneven terrain, as well as in hard-to-reach places (for example, under a bush). It is also less safe, since when using electricity there is always a possibility of electric shock.

What to look for when choosing a lawn mower?

Since the purpose of the scythe is precisely to mow vegetation, the first thing to do is to look at the cutting tool. Domestic lawn mowers are equipped with steel or plastic blades. A saw blade or nylon scaffolding is also used as a cutting part. Based on this, it must be taken into account that the fishing line is absolutely unsuitable for work in areas where there are thickets of bushes. She also will not be able to cut small branches and young shoots from trees. Plastic knives, in turn, cannot be sharpened.

It is better to purchase more versatile models that have the ability to change the cutting tool. In this case, you need to ask how easily and quickly such a replacement is made. You need to understand that steel knives and discs become dull during operation. What then? If they are sharpened, how? Can you do it yourself? If the manufacturer provides spare cutting tools, how much is included in the package and can be purchased at retail? After all, the lawn mower itself is designed for a long service life. A steel knife may break, but where to get another?

Chainsaws are usually equipped with a 2 or 4 stroke engine. The first ones are somewhat lighter, but their operation is much more noisy. Although the set may include headphones that are used during work. Therefore, everyone chooses a model at their discretion. The scythe power can be up to 1.5 hp. Another such nuance of the 4T model needs to be kept somewhat tilted, at an angle. This is necessary for oil to get on all parts of the braid. But the 2T models can be held as you like, in any position they work stably.

Practice shows that corner models are less reliable, and their power is less. However, with a bent bar, steel knives are not used, since with such a configuration, the knife is easy to break. There are models with a folding bar, but they are short-lived.

The handles can be of various shapes. They are called T, D or J shaped. The T-handle is well suited for work in open and relatively level areas. This configuration follows the shape of a traditional braid and allows for large, wide sweeps. The D-shaped handle is more suitable for working in difficult areas: along fences and buildings, under bushes, among trees. For areas with high vegetation, a scythe with a J-handle works well. By the way, it is the best in terms of safety.

And yet, focusing on the technical characteristics and cost of a particular model, do not forget about the convenience of using this particular braid. If it fits well in your hands, does not impede movement, then, most likely, your choice was made correctly. I recommend watching a specialist tells about the choice of lawn mowers and its maintenance:

How to choose a lawn mower?

How to choose a lawn mower for the landscape? What are the different models intended for? Which device will be most convenient for you personally? Our review will help you understand the external characteristics and internal structure of lawn mowers before purchasing the right machine.

A lawn mower consists of the following elements:

1. Motor.
2. Barbell.
3. Handle.
4. Cutting element.

Engine’s type

There are two- and four-stroke engines. Two-stroke models are cheaper, easier to maintain and operate, but noisier The four-stroke engine is much quieter, but weighs more and costs more. The motor can be located at the top or bottom of the unit.

Boom design

The main bar can be straight or angled, solid or foldable. The advantage of the angled version is its great maneuverability. However, the power of such a device is less. The folding mechanism allows the lawnmower to be compactly stored for storage, but the overall structural strength is reduced.

Lever

Lawn mowers differ in the shape of the handle:

  • T-shaped is designed for work in open areas, allows you to make wide, exciting movements;
  • D-shaped is used in confined spaces, near walls and fences, among trees and bushes;
  • J-shaped is the safest shape, convenient for processing areas with tall grass and undergrowth.

Types of cutting elements

The following can be used as a cutting element:

  • Fishing line of various thicknesses and shapes for grass cover;
  • Steel knives with different numbers of teeth for thickets of different thicknesses;
  • Non-re-sharpening plastic knives for moderate work.

Technical specifications

In order to most accurately answer the question of how to choose a lawn mower, it is necessary to take into account the following characteristics of the device:

  • Power;
  • Engine’s type;
  • Volume of the tank;
  • Brand of gasoline;
  • Speed;
  • Cooling;
  • Shaft placement;
  • Working area;
  • Dimensions;
  • Weight.

Also pay attention to the possibility of changing the cutting heads and their availability in the delivery set. A useful addition will be a shoulder strap that will make it easier to work with the device for a long period of time.

Our consultants will acquaint you with the entire range of products and help you choose a specific model.

Functional features of the use of lawn mowers

There are two types of lawn mowers on the market today. The former are equipped with a 2-clock motor, and the latter are equipped with 4. The peculiarity of using 2T braids is that they will not require the owner of certain operating conditions of inclination for lubrication, significant force during transfer, but they will be noisier, which means that it will be extremely difficult to work without headphones. At the same time, they will have a light weight and a reasonably comfortable working practice.

One of the most important criteria that can help the buyer understand which lawn mower to choose for a summer residence or a backyard is the configuration of the handle and knives. The handle of the scythe itself can be straight or bent, and the strength of the knife will depend on this. The fact is that when the handle is bent, the knives are very easy to break, and steel parts are simply not used there, however, using them is much more convenient and simpler. Smooth handles are almost always equipped with steel cutting elements, which means they will be able to cope much better with the main task of cutting grass.

What are the best lawn mowers?

Many buyers who plan to acquire such a unit are concerned not only with the question of how to choose a lawn mower for a summer residence, but also with whether it is possible to replace a broken blade. Yes, this question is really important, because many are faced with a problem when dense parts of stones and parts of strong metals get into the structure of the braid and they can very easily and quickly remove from standing, not only the cutting element, but the entire braid. In addition, do not forget that the braid itself can be used for a long period of time, and the strength and configuration of the blades can extend its life and avoid major repairs.

Most of the products are designed in such a way that when solid particles get in, they simply stop working, this is the right approach to avoid serious damage. Perhaps, given this feature, it is worth choosing a semi-professional lawnmower, which necessarily provides for such an unpleasant situation and will react accordingly.

How to choose a lawn mower?

The process of mowing grass always requires a significant amount of time and effort from the owner, because the ideal maintenance of a large area is painstaking and difficult work. In an effort to help customers get more information on how to choose a lawn mower for their home, garden or vegetable garden, we have prepared a short tour of the main and auxiliary functions of this garden equipment.

It is very important for every person who lives in the private sector or owns a country house to constantly monitor the state of the territory that surrounds it, and if, on top of that, the house has a garden or a summer cottage, putting lawns and lawns in order becomes a matter of not only aesthetics , but also the yield in this area. Many hobby gardeners often resort to choosing the right equipment that can quickly and easily eliminate complexities and take over most of the work. In order for such units to be productive and functional, to work properly and for a long time, it is worth knowing which lawn mower is better or how to choose a lawn mower. It’s no secret that such tools come in several varieties, in different price categories and levels of professionalism, however, not all potential buyers understand that the choice of lawn mowers depends solely on their preferences, wishes and capabilities.

Which lawn mower is better or how to choose a lawn mower

Every summer resident or gardener sooner or later has a question of mowing grass, as well as a question of weed control. Many people solve it with the help of an old but reliable old-fashioned hand scythe tool. Who does not remember the proverb koshi scythe while the dew is. But if the site is large enough, but there is not enough time, or simply laziness overcomes, then you can use mechanized assistance. Today we will talk about how to choose a lawn mower.

A lawn mower (gasoline lawn mower, trimmer) is a special garden tool that is designed to mow grass or small bushes using a gasoline engine.

For lawn mowers, as well as for chainsaws, gasoline of the A-92 brand is mainly used, although it is better to look at the instructions for each specific tool.

In addition to gasoline lawn mowers, there are also electric lawn mowers that use an electric motor instead of a gasoline engine. However, a robotic electric lawn mower needs a connection to the electrical network, which is not always convenient and possible.

Let’s list the main parameters of lawn mowers, which are key when choosing it:

1. The power of the lawn mowers.

Lawnmowers’ power is measured in watts or horsepower. The conversion of watts to horsepower is as follows: 1 kilowatt = 1.36 horsepower.

In order to mow a relatively small lawn with grass, 0.8-0.9 kW of power may be enough, however, in order to mow areas with weeds, etc. You need to choose a lawn mower with a power of 1.2 kW. Professional lawn mowers can have a power of 3 kW or more.

2. Engine type.

Most lawn mowers have two-stroke engines. This can be said to be the standard for lawn mowers. However, over time, lawn mowers, which have a four-stroke engine, are increasingly starting to appear on sale.

The 4th stroke engine is less noisy and more reliable, but it weighs more and such tools are more expensive.

3. Type of cutting element.

Lawn mowers use two main types of cutting elements: knives and special line.

Lawnmower line is used when mowing grass. It can have different diameters (mainly from 2 to 3 mm).

The lawn mower blade can be metal or plastic, and it can have 2.3 or more cutting surfaces. With knives, you can cut harder grass, weeds and even bushes. If handled carelessly, the knife can also mow a young tree.

Most modern models of lawn mowers are designed in such a way that they can be hooked to both a bobbin with a fishing line and knives. Be sure to make sure you have this option when choosing lawn mowers.

4. Weight of the lawn mower.

Although a lawn mower is easier to mow than a regular lawn mower, it also needs to be handled. The weight of the tool determines how long you can work.

On average, lawn mowers weigh between 4 and 8 kg. The weight of a lawn mower is directly influenced by its power. The more powerful the instrument, the heavier it is.

On average, focus on a weight of 6.5-7 kg. For a medium power streamer.

Be sure to make sure that the lawn mowers have a special belt in the kit, which allows you to redistribute its weight not only on the arms, but also on the torso, which greatly facilitates the work and reduces fatigue.

I also need to say a few words about brands and prices.

Lawn mower manufacturers can be divided into three conditional groups: famous brands, good China, just China.

Well-known brands such as Alpina, Stihl, Oleo-MAC, Husqvarna produce quality but expensive products. Low-power models from these manufacturers start at 250, and medium-power models from 300-350.

If you want to have a really reliable unit that you will often use, take a look at these brands.

If you don’t want to overpay for the brand, look for normal china lawn mowers. Almost all of them are now called by big names such as Temp, Vityaz, etc. It doesn’t hit here once at a time. You yourself need to look at the quality of materials and assembly of a particular braid. There are quite good models of lawn mowers with a price of about 140-180.

Ordinary China is anything that costs about 120 or less. There is already a real lottery, the tool may or may not work well. Such Chinese lawn mowers can be taken only if you need to mow something not very large-scale from time to time.

Well, I hope now you will be aware how to choose the best lawn mower for your garden, vegetable garden or cottage.

Repair of the starting device

Dismantling the starter to replace the cord does not create problems for an experienced user, but the plastic case in most cases cannot be repaired. Most of the Chinese chainsaw range is copies of the most popular European models, therefore we disassemble the Chinese chainsaw according to the standard scheme.

The worn parts of the saw headset are not restored.

  • At home, you can shorten the new chain to fit a shorter bar.
  • The service life of branded tire accessories is equal to that of three saw chains.
  • This indicator can be significantly reduced by the wrong choice of the chain pitch or large wear of the rim of the drive sprocket.

Fault determination algorithm

Saw failure or poor performance can be caused by:

  • Clogged fuel tank cap breather;
  • Air leaks by the carburetor due to destruction of the gasket or loosening of the threaded fasteners;
  • Mechanical seizure of removable saw equipment and other minor defects.

Before starting disassembly, make sure that more extensive repairs are necessary.

It is most likely that you will not be able to assemble a new chainsaw yourself after repair with the original quality. In the design of modern chainsaws, press fits of mating parts are often used, which have minimal maintainability.

Even a partial disassembly of the chainsaw with the help of an improvised tool can lead to undesirable consequences. In most cases, to eliminate the malfunction, you can limit yourself to dismantling a separate unit or system.

This list includes:

  • Connecting rod and piston group;
  • Carburetor;
  • Clutch mechanism;
  • Chain drive sprocket.

Self-repair problems

The problem in many cases is aggravated by the lack of comprehensive information on repair technology. According to foreign manufacturers, after the resource has expired, the saw should be scrapped, therefore, the maintainability of many models of the budgetary level raises reasonable doubts.

It is more difficult to restore professional-grade chainsaws.

  • The problem is compounded by the high cost of spare parts.
  • It is possible that special equipment will be required to restore the operability of individual units and mechanisms, in particular, to adjust the fuel equipment.

Replacing expensive branded parts with affordable, but short-lived Chinese counterparts does not justify itself economically. Practice shows that these components develop a resource by 50-60% at best.

Compression recovery

Less complicated repair of the piston group. To dismantle the cylinder, it is enough to remove the threaded fasteners, lay the saw on one side in order to prevent pieces of the destroyed compression ring, piston skirt or other foreign objects from entering the engine crankcase.

The cylinder mirror wears out unevenly, so installing a new piston does not give a significant effect. As a rule, during overhaul, after checking the suitability of the crankshaft, a complete set is installed, consisting of a cylinder, a piston of a compression ring and a piston pin.
