How to drain oil from a lawn mower

A gas generator. a device that turns the internal energy of fuel ignition into an electrical. It consists of two main parts: ICE (internal combustion engine) and an electric generator. Brief principle of operation of the device: a gasoline (two or four.stroke) engine rotates the shaft of the generator, which gives the necessary voltage level, pre.missing it through filters. Figuratively speaking this is a mini.electrical station. There are also inverter gas generators that differ in the presence of an inverter and a block of wide-pulse modulation. They are designed to create a stable voltage at the output of the generator.

Everything in our world is free. And your favorite generator is not eternal, sooner or later he will refuse to help you. Consider the possible causes of these situations and ways to eliminate them. Since the device constructively consists of two parts, the repair tips are divided into two parts:

1 malfunction of the internal combustion engine.

We include the lack of oil, pure air filter, fuel to malfunctions. These are very important “elements” of normal work, without them many models do not start (protection is triggered), they stall without the supply of oxygen and fuel. Therefore, follow the cleanliness of the fuel filter and “readiness” of the air filter (in no case should it be in oil).

Another of the reasons is the lack of sparking spark. To eliminate the malfunction, unscrew the candle (there is a special key for this), clean it with an iron brush and sandpaper from the soil, wipe it with alcohol and dry. Next, check the spark and start the generator. Remember that the cargo is formed when using poor-quality fuel, due to incomplete combustion of fuel.


Perhaps additional adjustment of the carburetor is required, but still soot occurs when the generator works at an incomplete load. Larger breakdowns. A malfunction of the piston, carburetor, revolutions will help to eliminate experts. Without proper experience, it is better not to try it yourself.

In the complete absence of voltage, disassemble and inspect the device, in this case, anything can be of anything from the lack of contact, a malfunction of the brushes to the burnout of the capacitors, shim blocks, etc.D. If the engine speeds are stable and the voltage jumps, then AVR (excitation regulator) is possible. Before changing the burned blocks, it is necessary to establish the exact cause of its failure. Because many people have enough skills to change the diode bridge, capacitor (possibly even IGBT transistors), but so that the story does not repeat it again, you need to check all the elements of the gas generator. And in this case, again. Seek for help to specialists.

Preparation and configuration

The location of the lawn mower is important when preparing this machine for oil replacement. Due to the likelihood of leakage, it is better not to perform such work on the grass or next to floral flower beds, since the ingress of oil drops can poorly affect plant life. Choose a solid flat surface, such as a passing part or sidewalk, and be sure to use polyethylene film so that oil drops and spots remain on this protective film.

Gouched oil is much easier to replace. Of course, you can change the oil in a cold engine, only the lubricant will be more viscous only at high temperatures.

It is considered a good rule before replacing the lubricant to run the lawn mower for one or two minutes to heat the engine a little. After which you will have much fewer problems with the extraction of an old lubricant. It is also useful to take precautions when working with a mower after turning on, since the probability of a burns about the engine, for example. It is recommended to use working gloves to reduce the risk of injury.

And finally, you can disconnect the spark plugs wire from the candle itself and remove it away to avoid random starting the engine. And also you need to make sure that the pump (pump) is disabled. The last step in your preparation should also include cleaning the area around the opening hole to prevent foreign particles or dirt in the oil tank.

Knife sharpening

After removing the blade is often either replaced with new ones, or the existing. High.quality products amazed to “renew” several times and are subject to replacement only with the thinning of the plate itself or rounding of the corners of the knife.

For the process itself, you can use a grinding workshop and not forget about the protective mask and gloves. When operating the corner grinder, it is necessary to hold the blade itself in a vice. The file is also considered as an option, but working with it requires a lot of effort and time.

Filling out the tank

Now that the old oil is removed, it’s time to fill the reservoir with fresh grease. Once again, contact the guide to use the lawn mower to find out which type of oil is suitable for your unit, as well as in what quantity it is required to fill.

Keep in mind that overflow and insufficient filling of an oil tank can harm the operation of the lawn mower.

Fill in an oil tank. Give the clock to settled for at least two minutes, and then check the level with the probe to make sure that the filling is correct.

After the oil tank is filled to the proper level, you will need to fix the spark plugs again. Do not turn on the lawn mower immediately, let the car stand for a few minutes before starting work.

Differences in engines in lubrication methods

A significant point is the difference in the method of lubricating two.stroke and four.stroke internal combustion engines: the former requires refueling with not clean gasoline, but its mixture in the necessary proportion with oil. She, connecting with the air, circulates in the piston node, while lubricating the walls of the cylinder, crankshaft bearings and connecting rods, as well as the pistons themselves. Когда топливная смесь загорается, то масло, мельчайшими каплями входящее в ее состав, также сгорает. Combustion products come out in the form of waste gas. In practice, oil mushrooms with a two.stroke engine is mixed with gasoline in certain proportional ratios.

There are 2-stroke engines with a separate intake of these components of the fuel mixture, but on mowers this more perfect option is not installed.

When the engine is 4-stroke, the oil is supplied separately, without mixing with gas. Almost lubrication is implemented due to the presence of pipelines, oil pump, valves, filter. The latter is designed to clean the oil from small particles of metal formed during the wear of the parts.

It turns out that in 2-stroke engines the oil burns during operation, but in 4-stroke there is no, remaining a long period to circulate in the system. Because of this, the requirements for its operational properties differ. After combustion, two-stroke engine oil should leave the minimum possible amount of soot, and for four-stroke units it is necessary for the lubricant used for a long time to maintain its initial physicochemical indicators.

Replacing 4-stroke oil mowing Husqvarna ??

It turns out that it is much more convenient to change oil with a long neck. I poured fresh corrugated oil

If the engine is not new, oil for the lawn mower can be changed about once every 25-50 hours of operation of the tool. Replacing the sprocket on the Husqvarna chainsaw recommendations: how to remove an asterisk from the chainsaw of the clutch drum is equipped with a chainsaw there are many algorithms for replacing the clutch drum. This is an average of 2-3 months of work. You can also find out the condition of the oil without measuring the number of hours worked. Replaced oil in the Husqvarna lawn mower, which replaces oil by tipping over a lawn mower. Just make sure that he does not start darkened. When this happens, be sure to replace the liquid, otherwise the engine can soon jam.

Change of oil

And now about how to change oil in the lawn mowers. The whole process can be divided into several stages:

  • First we combine the ancient liquid.
  • Then the lawn mower rotates to the side (from the side where the drain hole is located) for a couple of minutes, until the wastewater flow one hundred percent. Then the tool is returned to a horizontal position. With all this, you need to prepare a small container for old oil in advance.
  • Then the new one pours through the mouth into a lawn mower.

At this stage, the oil change can be considered complete. Filling your neck with the last liquid, do not forget to pour it strictly to the mark in the crankcase.

Which lawn mower to choose?

It should be emphasized that a certain type of water and its viscosity directly depend on the temperature criteria in which this tool is used. So, if the weather is warm (temperature from plus 5 to plus 30 degrees Celsius), it is recommended to use the liquid of the SAE-30 series. Therefore, oil replacement is required. When using it, change the oil in the lawn mowers. Replace once a year. 2. Oil change. In the Husqvarna law mower or. In the offseason, experts advise pouring oil for lawn mowers with a viscosity of 10 BT-30. In winter, you can use the 5W-30 fluid

It is also worth paying attention to the Synthetic 5W-30, which with its properties provides reliable operation of the lawn mower at relatively low temperatures


From a wide range provided by the manufacturer, you can choose a technique that will satisfy the tastes of the most demanding consumer.

Gardeners, gardeners and employees of the park can choose different models that are classified in accordance with:

  • Movement mode (non.self.propelled and self.propelled);
  • power source (electric and gasoline);
  • Design features of herbal block.

Additional equipment significantly accelerates and facilitates the process of bringing the lawn into proper condition.

Gas braids

They have several advantages, including:

  • The presence of an internal combustion engine. Thanks to the energy of the fuel burned in the chamber, the device demonstrates high efficiency and decent power.
  • Mobility. The device is not connected to the power source. Can be used in remote areas.

For a note. The housing (deck) of the lawn mower is made of a very durable alloy, which protects the device from damage.

Self.propelled models

Benzin MTD self.propelled lawn mower makes the mowing process more efficient. It moves on the surface of the site, independently performing the necessary operations. The only thing a person needs to do is follow the instructions of the device.

Models with front.wheel drive MTD gasoline braids are more maneuverable and convenient to use on hilly terrain. They are equipped with stainless steel knife and a regulator for choosing the optimal speed of movement.

How hydraulic jack work

Another advantage of MTD lawn mowers and their self.propelled gasoline models is the presence of herbs. Large rear wheels with a tread facilitate the movement of self.propelled tools. Models of this category include self.propelled devices MTD 46S Promo, MTD Smart 46 SPO, MTD Smart 53 SPO. They will continue to work under warranty for 3 years after purchase.

Lawnmands that do not work on their own

They are suitable for an area of ​​up to 8 acres. The main detail. very sharp steel knife. A 60.liter.liter collection container and a four.stroke engine with a cooling system. Manual mode.

Trammers for grass and braids. These are manual motorized tools that are used on relatively small areas. Trammer for grass is equipped with a scallop that easily mows thin grass. On motosans, you can change nozzles, they cut off the vegetation between the trees, under the fences, along the walls. Moto or bureau is equipped with a two-stroke gasoline, sometimes four-stroke engine. As a working tool, a metal knife or saw is used.

Upon completion of sharpening

After the above procedures, you should not rush to install the blade, because you should check its balancing. To do this, you need to place a nail in the hole of the blade and make sure of the correctness of the work done.

If there is no necessary effect, the installation of such a cutting part can lead to the appearance of vibration and breakdown of the device itself. Therefore, you should fix the situation with a file or machine. After you need to install the blade in place and tighten the bolts.

Oil change

And now about how to change oil in a lawn mower. The whole process can be divided into several stages:

  • First, the old liquid is drained.
  • Next, the lawn mower rotates to one side (to the side where the drain hole is located) for several minutes, until the spent liquid completely cooles. Further, the tool is placed back in a horizontal position. In this case, it is necessary to prepare a small container for the old oil in advance.
  • After that, a new one is filled through the neck in the lawn mower.

Everything, at this stage, the oil change can be considered completed. When you pour a new liquid into the neck, remember that it is necessary to pour it strictly to the indicated mark in the crankcase.
