Typical breakdowns and repairs of a lawn mower with your own hands. High-quality care of the lawn mower is the key to its long-term use. Start the gasoline lawn mower.

Proper first start-up and running-in of the lawn mower are very important steps when starting to use a new tool. On the one hand, they allow you to preserve the service life of a gasoline engine, as specified by the manufacturer, since at this stage the grinding in of moving components and parts occurs. On the other hand, the first necessary skills of working with a trimmer are acquired, if we are talking about the first tool in life.

Preparing for the first start of the lawn mower

Before starting the lawn mower for the first time, it is necessary to perform a number of sequential actions:

Inspect the gearbox and lubricate it;
Prepare the correct fuel mixture.

Inspection of the lawn mower gearbox and its lubrication

Before starting a gasoline trimmer, the gearbox must be checked on a regular basis. Lack of lubrication or little lubrication increases friction gear transmission gearbox operating at fairly high speeds. As a result, overheating of the gears occurs. The brush cutter gearbox fails. Regular inspection helps prevent such damage from occurring during operation.

If, before starting the gasoline scythe, an insufficient amount of lubricant in the gearbox or its absence is detected, “LITOL” is placed in the housing. To do this, you need to unscrew the screw on the bend of the gear housing and spray in 1-2 ml of LITOL.

When working with a gasoline trimmer for a long time, add lubricant to the boom gearbox every 8-10 hours.

Preparing the correct fuel mixture

Before you start running in a new lawnmower engine, you also need to properly prepare the fuel mixture. As is known for two-stroke engines, it is prepared from special two-stroke oil and gasoline, taken in certain ratios. You can find out the proportions from the instructions included with the instrument or on the label lubricant. From the instructions you will also learn the recommended type of fuel, as well as the recommended type of engine oil.

Prepare fuel in small quantities, enough for one mowing of grass. Use special plastic canisters or separate glass or metal containers for fuel. It is best to draw up the oil with a medical syringe. .

Getting ready to run in new lawn mower, many people face problems in preparing the fuel mixture. And the reason for this is the discrepancy between the tool manufacturer’s instructions and the manufacturer’s instructions motor oils. The first ones recommend a proportion of 1:25. The second recommend 1:50. Who to believe? How to proceed?

According to experts, if manufacturers write a ratio of 1:25 or 1:30 in the instructions for a brush cutter, then most likely it is either a cheap tool with poor cooling, or the manufacturer does not know what kind of oil, the consumer will add. But here you need to understand that excess lubricant does not in the best possible way affects the performance of the trimmer. Excess oil does not burn out completely when the engine is running. It cokes and clogs the cylinder and piston.

What to do in this situation when running in a new tool? Ideal option will purchase exactly the oil that the lawn mower manufacturer recommends. In the case of run-in engines, when it is not possible to purchase the recommended oil, it is best to purchase a good Husqvarna two-stroke oil for the same name gas-powered tool. It's not cheap, but it lasts a long time. It must be mixed as written in the instructions on the can.

Remember, it is best to use the proportion provided by the oil manufacturer. But whether the proportion written on the braid is appropriate is better to find out through experiment. If, with the proportion recommended by the trimmer manufacturer, the engine is snotty with oil and smudges are visible on it, then the proportion needs to be increased.

First start of the trimmer

When everything is checked and the prepared fuel mixture is poured into the tank, the moment comes for the first start of the trimmer before running it in. To do this, you need to perform the following manipulations:

Place the brush cutter on a flat horizontal surface;
Move the choke control lever to the closed position;
We pump fuel into the carburetor with several pumps of primer;
Turn on the ignition switch;
Smoothly pull out the starter cord until you feel resistance;
Then make 3...4 sharp jerks with the cord until the lawn mower starts;
After starting, open the air damper.

If the lawn mower does not start or stalls the first time, slightly open the air duct damper on the carburetor and try starting again.

Let's start running in the lawn mower

After starting, do not rush to immediately break in the trimmer. Allow the engine to warm up at idle speed for 5 minutes. While warming up, adjust the air supply using the air damper lever so that the spool with fishing line or knife does not rotate. As soon as the tool has warmed up, we fully open the air supply by moving the corresponding lever to the “ON” position and squeeze the gas trigger 1/2 and hold for 20...30 seconds. Then we let off the gas and let the trimmer work for XX 30..40 seconds. We continue in this mode for 10…15 minutes. Then turn it off and let it rest for 15...20 minutes.

Having cooled the lawn mower, we continue to run in the engine according to the previous scheme. You need to start the trimmer when it’s hot, with the air damper already open. Try not to hold the gas for a long time, since the moving parts of the tool are only rubbing against each other. And don't let the engine run for too long. idle speed as it may overheat.

The next stage is running in the gas scythe gearbox. To do this, you need to choose an area with soft young grass. We mow for 5...10 minutes with throttle adjustments at 1/2...2/3 of full throttle. Afterwards we take a break for 20…25 minutes. We repeat the cycle 3…4 times.

In general, running in the lawn mower according to the described algorithm is carried out until the fuel mixture in the tank is completely exhausted. After which the tool is ready for long-term work. While working, keep an eye on temperature conditions gearbox and motor. They should not overheat.

lawnmower: advice from professionals

The advantage of gasoline lawn mowers

Main competitor gasoline lawn mowers are electric lawn mowers. The advantage of gasoline lawn mowers over electric ones is the following:

Does not depend on the availability of a power source
Have more powerful engine, which allows you to work on large lawn sizes
More maneuverable, because Dont Have electric cable, which will trail behind and cling to all obstacles.
A gasoline lawn mower can cut even regular, tougher grass.
Cheaper to maintain (although they break down more often)

Despite this, gasoline lawn mowers have several significant disadvantages, namely:

Making noise
Assume additional material costs for fuels and lubricants (fuels and lubricants)
Release of harmful exhaust into the atmosphere
Requires repair and maintenance more often

Recommendations for choosing a gasoline lawn mower yourself

Almost all the advantages and disadvantages various types petrol lawn mowers we have provided above, in brief description. But I would still like to draw your attention to some design features gasoline lawn mowers, which should be taken into account when purchasing a unit.

So, professional gardeners We provide you with the following recommendations for choosing a gasoline lawn mower:

When buying a gasoline lawn mower, pay attention to the diameter of the wheels. The larger the diameter, the more maneuverable the unit will be, and therefore the more comfortable the process of mowing the lawn.

By the way, the width of the wheels should also be taken into account, because... narrow wheels will push through the lawn, leaving unattractive marks.

The mower deck must be aluminum. In this case, the mower itself will be lighter, more resistant to mechanical damage and the formation of corrosion.
If you choose a unit that is not powerful enough, the grass catcher should be plastic, because... It will be more convenient to clean the container from grass.
Give preference to lawn mowers with folding rubberized handles. They are easier to transport and vibrations from the engine will be felt less.
The mowing height should be adjusted by the central lever; this is more convenient and will allow you to cut the lawn more evenly throughout the entire area.
Pay attention to the lawn mower’s executive body – the blade. It should be sharp and preferably wide. This version of the lawn mower will cut the grass more efficiently.
Choose a gasoline lawn mower whose wheels are on bearings, because... conventional plastic bushings fail faster and are less resistant to mechanical damage.
One cannot fail to mention the engine power. Based on the area of your plot, choose an engine with a power reserve so that you can cut the grass in any weather. Please note that self-propelled lawn mowers take away part of the engine power for movement, this also needs to be taken into account.
Give preference to lawn mower manufacturers such as: Honda, Hitachi, Craftsman, Viking, MTD, Stihl, Husqvarma, Stiga, Makita, etc. Pay attention to the manufacturer of the gasoline lawn mower engine; the leaders are Briggs & Stratton and Honda.

When using any equipment, the main thing is to handle it carefully and follow the operating rules. In this case, the device will serve you faithfully for a long time. However, it still happens that the tool breaks. Of course, you can entrust the matter to professionals and take it to service center. However, you can often fix the problem yourself. In this article we will explain what to do if lawn mower won't start.

Why won't my lawnmower start?

The answer to this question depends on which model you are working with: gasoline or electric.

Key points to consider when working with a petrol model:

1. Before starting the lawn mower, you first need to check the availability of fuel. Please note that you should not pour fuel to the brim. Usually the tank has a maximum fill mark. You need to pour gasoline carefully, preferably through a funnel. If fuel gets on the engine, it can cause a fire or even an explosion when heated. Over time, the gasoline left in the device “exhausts.” Therefore, it is recommended to drain it in the winter.

2. You need to start the device correctly. When starting the lawn mower, set maximum speed and prime the carburetor with fuel. Smoothly pull out the starter cord to maximum length and pull it towards you with a sharp movement.

3. Another reason why a lawn mower won't start is often a faulty spark plug. In this case, it must be cleaned or replaced. Remove the candle from the device. If there is plaque on it, blow it out or replace it with a new one. After installing the spark plug in place, close the air damper.

4. Pollution air filter may also be causing startup problems. Turn off the device and disconnect the wire from the spark plug. After removing the filter, rinse it thoroughly with gasoline and dry it. The operating instructions recommend doing this after every 25 hours of operation.

5. If the lawn mower stalls immediately after starting, most likely the reason is a stuck piston or crankshaft. Carefully move these parts and the problem may be resolved.

6. Also, do not forget to check the oil in the crankcase. An insufficient amount of it may cause the lawn mower to not start.

Information for owners of electrical equipment

1. If you use an electric lawn mower, you should make sure that the cord is connected before starting. It is also worth checking the electrical panel. The circuit breaker may have switched off or the fuse may have blown.

2. There is a possibility that the lawn mower does not start due to thermal protection. Check the ventilation grilles: is there grass clogged there? Clean them if necessary and allow the engine to cool.

3. Another reason why a lawn mower may not start is a broken switch. In this case, you need to take the tool to a service center.

As you can see, in many cases problems can be fixed without the help of a specialist. The main thing is not to replace parts yourself. In such cases, it is better to trust the professionals.

a short period of time to process a huge area;
created for a plot of more than 3 acres;
work with ease even on a site with difficult terrain;
have the highest power;
They can not only cut lawns, but also mow them.

Thus, household lawn mowers are ideally suited for small areas of up to eight acres, their power reaches 5 horsepower, the longest resource is about 500 engine hours

With all this, you should know that, usually, companies that produce this kind of equipment do not manufacture engines themselves, but install ready-made ones from companies such as Tecumseh, Subaru, Briggs & Stratton. The only exception is the Honda brand.

Directly about work

Depending on how the height of the mowed grass is adjusted for each device, they can be divided into several types:

safety when working with a lawn mower

All lawn mowers also move differently, this is explained by the difference in drives. When thinking about how to choose a self-propelled gasoline lawn mower, you need to pay special attention to this nuance:

If the device is equipped with a front drive, it will be very maneuverable, but in the process of filling the container for mowed grass, the front wheels may slip, since the center of mass in this case will be shifted back.
Rear-wheel drive is more comfortable, here the main load falls on the rear wheels.
