Oil for lawn mowers with a 4-stroke engine

Lawn mowers have long taken their place among the necessary equipment from owners of country and private houses, as well as employees of parking institutions. In the summer, such a technique is operated quite intensively. For reliable and durable operation of the gas mowing engines, the quality of fuel and lubricants is important, in particular, oils. About oils for 4-stroke engines of this type of garden machines and is described in this article.

The gasoline engines of lawn mowers belong to internal combustion engines (ICE), in which the driving force transmitted from the ICE to the working bodies (cutting knives) is formed due to the energy that occurs in the combustion chamber of the cylinder during ignition of the fuel mixture. As a result of the fire, the gases are expanding, which makes the piston moved to move the mechanism of further energy transfer to the final organ, that is, in this case, the lambs of the lawn mower.

In the engine, thus, many large and small details are in conjunction, which need lubrication in order to completely prevent their abrasion, destruction, wear, then at least slow down these processes negatively possible for the mechanism.

Due to the engine oil, which enters the engine and covers its rubbing elements with a thin layer of oil film, the occurrence of scratches, nozzles and burrs on the metal surface of the parts practically does not occur on new units.

But over time, this cannot be avoided, since the development of clearances in the conjugation still occurs. And the better the oil, the longer the service life of the garden equipment will be longer. In addition, the following positive phenomena occur with high.quality lubrication:

  • the best cooling of the engine and its parts, which prevents overheating and thermal blow;
  • The engine operation at large loads and with a large time period of continuous mowing of grass is guaranteed;
  • the preservation of the corrosion of the internal parts of the engine during seasonal downtime of technology is ensured.

Features of the four.stroke engine

Gasoline engines of lawn mowers are divided into two groups: two.stroke and four.stroke. Their difference in the method of oil filling is as follows:

  • A lubricant for two.stroke engines should pre.mix with gasoline in a separate container and in a certain ratio, mix thoroughly, and even after all this is poured into the fuel tank of the machine;
  • Lubrication and gasoline for four.strokes are not pre.mixed. these liquids are poured into separate tanks and work separately, each according to its system.

Thus, a 4-stroke engine has its own pump, filter and pipeline system. Its oil system is a circulation type, that is, unlike a 2-stroke analogue, the lubricant in such a motor does not burn, but is supplied to the necessary details and returned to the tank.

Based on this circumstance, the requirement for clockwork here is also a special. It should maintain its properties for a long period when, as for a lubricating composition of a two.stroke motor, the main criterion of quality, in addition to the main properties, is the ability to burn without a trace, without leaving soot and deposits.

How a gas station is arranged?

The basis of any such device is:

possible, turn, lawn, mower, drain, lubricants

Frame. This is the basis of any lawn mower, because it is to it that the engine and other elements are connected. On some models, the frame is made for one whole with the neckline.

The main elements for the manufacture of the frame are:

The steel frame is very durable and therefore can be used in the most difficult conditions. However, it is very vulnerable to corrosion, which occurs due to exposure to the water frame and various substances that occur during the muffling or decay of grass caused by poor cleaning of the device after operation.

Paint (LKP) protects the frame from the effects of aggressive substances, however, the reliability of such protection depends on the cost of the device, since the most reliable powder dyes are used only for painting expensive models.

The aluminum frame is deprived of these shortcomings, since aluminum is inert to water and weak acids, but its manufacture is much more expensive due to the higher cost of the source material. The paint of such a frame performs only decorative functions.

The plastic frame is very economical and, like aluminum, is not afraid of water and acids, but its mechanical strength is ten times lower than that of its aluminum or steel analogues, so machines with a plastic case can only be used for ordinary lawn haircuts.

Any attempt to mow with their help tall grass or weeds, as well as a knife blow against an unexpected obstacle will lead to a break in plastic, which is why the whole structure will begin to vibrate, and therefore it can fall apart.


The lawn mowers are equipped with four.stroke gasoline engines of various capacities, but the overall design of these engines is the same.

Below is an oil pallet (crankcase), in which there is a supply of oil and where it flows after lubrication of all engine elements.

Above the card there is a cylinder block and a crankshaft with a sliding bearing and a connecting rod, and the shaft passes through the crankcase through high.quality oil seals that prevent oil leaks.

On the side of the block, a combustion chamber is installed, that is, a cylinder and a piston with piston rings, as well as a cooling radiator that removes excess heat from this element. The engine head is installed on the side of the combustion chamber, where the distribution shaft and valves are located.

The crankshaft and the camshaft are interconnected by a chain gear with gears of different sizes, so that the distribution shaft rotates only 1 time in 2 crankshaft revolutions.

The following units are connected to the engine shaft:

  • manual or electric launch;
  • generator;
  • ignition sensors;
  • friction sleeve or adapter that protects the shaft from deformation with a sharp stop of knives.

The engine power depends on three parameters:

The diameter of the cylinder and the piston stroke form the volume of the combustion chamber, so some manufacturers in the documentation of the lawn mowers indicate not the power in the horsepower (l.With.) or kilowatts (kW), and volume in cubic centimeters (cm3).

Reducing the diameter of the cylinder, but increasing the piston, the manufacturer supports the engine volume and thereby increases the power, but the price for such an increase. A sharp increase in the load on valves and rings.

It is difficult to determine the most vulnerable part of the engine, because in the case of overload of the valve and the rings are damaged, and when using poor oil or its premature replacement, the sliding bearing of the crankshaft (sleeve) and the piston contact points are subject to the greatest effect.

The main task of the deck. Not only to prevent the scattering of grass in different directions, but also to create conditions so that the rotating knife twisted the air to raise crumpled grass, facilitating the haircut.

DEKU is made of the same materials as the frame, and on some models both parts form a single whole.

When mowing the grass, the knife rotates at a high speed, so it will not only chop vegetation, but also scatter a crushed green mass around itself, including vegetable juice, as well as stones or ground if the knife meets them.

When mowing, the green mass does not even damage the steel case, however, after mowing, if this part was not thoroughly washed, the decomposition processes begin in green, which are caused by various bacteria.

We have already talked in detail about the activities of these microorganisms (bacteria), as well as about the products that they emit. Organic acids secreted by bacteria very slowly destroy the paint that protects the steel sheet, and when the paint is damaged, the metal is corroded, causing rust.

possible, turn, lawn, mower, drain, lubricants

Most lawnmands are equipped with special reinforcement, through which it is washed with a stream of water, in the absence of such a connection, the mower will have to be turned over and washed with a stream of water from the hose. In fact, in addition to corrosion exposure, the green mass, adhering to the internal walls of the plate, worsens the creation of a whirlwind that lifts grass in the knife area, which leads to a sharp decrease in the quality of the cut.


Frames differ both in the number of wheels and the method of attaching them.

  • Two.wheeled (such frames are used only for black cutters and machines designed to haircut weeds or hay);
  • three.wheeled (such frames are of maximum maneuverability);
  • On four wheels.

By the method of attaching the wheels of the frame are divided into:


The transmission is installed only on self.propelled models, because it transfers rotation energy from the engine to wheels.

  • Mechanics (belt), the belt of which not only transfers energy to the wheel gearbox, but also acts as a coupling, connecting the wheels with the rotating shaft of the motor or disconnecting them.
  • Mechanical (variator). It also has a belt that performs clutch functions, as well as variators of various types that change the speed of rotation of the wheels.
  • Hydraulic: these transmission can be with or without a belt. In addition, all the main manufacturers of the self.propelled equipment that we talked about here are trying to develop their own types of hydrotransmissions, as well as constantly increase their reliability and ease of use.

TILTING your lawnmower to the CORRECT side (and the reason why)

In the manual transmission, the most vulnerable parts are the belt and gearbox, but the belt is considered consumable, so its timely replacement will protect from serious problems.

How to start the device?

How to properly start the engine described in detail in the instructions for the selected model of the lawn mower, so the start of the engine in a full.functional machine does not cause any difficulties.

If compliance with all recommendations did not lead to launch, the engine or any additional equipment is faulty or incorrectly configured, then the lawn mower needs to be maintained or repair.

information about the malfunctions of the lawn mower, as well as about ways to eliminate them, you will find in this article (malfunction of a gasoline lawn mower).

If there are no instructions for using the device, it is necessary to act as described below.

First step. Carefully look at the rake to find all the commands related to the engine, namely:

  • Turning / off button or toggle switch;
  • manual trigger handle;
  • electric launch button;
  • handle of the throttle;
  • Fuel pump button;
  • throttle control lever.

On inexpensive models of lawn mowers, which cost less than twenty.five thousand, almost all of these elements are often present, with the exception of the electric starter button, but there are models without most of these elements or with an electric starter button.

On more expensive models, there is usually only a toggle switch and engine stop, as well as a handle for manual launch, all other elements operate in automatic mode and do not require the intervention of the operator.

Then perform the following sequence of actions (if there are no elements, then they work in automatic mode or you could not find them):

  • Check the oil level and gasoline;
  • Turn on the toggle switch to turn on and off the engine;
  • pump up fuel using the corresponding button;
  • Translate the throttle control lever into the starting regime or to the “Off” position;
  • pull the starter’s cable until significant resistance;
  • Carefully, but with force and quickly pull the starter cord over yourself;
  • If the engine does not start, repeat the last 2 operations 2-3 times;
  • If the engine still does not start, it is necessary to find or diagnose the missing checks in order to detect and eliminate the problem.

The difference between electrical starters is that instead of using the starter’s traction cable, the electric start button is pressed and retained for 1-2 seconds.

Launching the lawn mower

Before you start a gas mowing gasoline, a visual inspection should be carried out for visible damage. The process of starting the unit is conditionally divided into several stages.

Preparation of the fuel mixture, refueling

If the launch of the lawn mower is carried out after the winter, the contents of the tank are checked: in the presence of unused fuel, it should be drained. Then you can start refueling equipment

For refueling two.stroke engines, it is necessary to use the fuel mixture. It can be purchased in the finished form or prepared yourself. There is nothing complicated in the preparation of the mixture, but you need to adhere to the necessary proportions.

When using synthetic oils, a proportion of 1:50 is used. 5 l of gasoline 100 g. oils.

When using mineral oils, the proportion is 1:35. 100 g. Oils at 3.5 l of gasoline.

Four.stroke engine refueling does not require preparation of the fuel mixture. A special crankcase for oil is provided here, gasoline is poured separately

It is important to remember that the oil also requires replacement, depending on the intensity of using the lawn mower. It is mainly necessary to change the oil every 50 motorcycles or at least once a year

Important! Lawn mowers work well when using oil with viscosity index SAE-30. In addition, if the engine is carried out in synthetic oil, in the future it is impossible to replace it with mineral and vice versa and vice versa

As for gasoline, the lawn mowers of Chinese, Japanese and American production work well on the fuel of the A-92 brand, it is better to use gasoline with a large octane number for European models.

When refueling the mower, you need to ensure that the level of gasoline is 2-3 cm below the edge of the fuel tank.

Launch of an unheated engine

Before you start an unheated lawn mower, a transmission, ignition system, and a motor shaft with a starter or starting cord is scrolled.

If the lawn mower does not start, you will have to carry out a number of manipulations:

  • The damper remains closed, the ignition is on;
  • The fuel pump button (suction) is pressed about 5 times;
  • An attempt is made to start a motor.
  • open the damper to prevent suppositories for filing candles;
  • scroll the shaft with the starter;
  • blow the combustion chamber;
  • start the engine.

Sometimes for the first launch of the motor it may take about 15 jerks. this is quite normal for this technique.

When the engine starts, the gas lever is squeezed out once to use idle. Then the lever is set to a position corresponding to low speeds. In this position, the engine should work for about 5 minutes to warm up. If necessary, its work can be stopped by pressing the “Stop” button.

Attention! It is not recommended to work with an unfinished engine. this affects its performance and durability

Launch of a heated engine

The launch of a pre.warmed motor is much simpler and no longer requires such efforts:

Errors at start

The most common errors when starting a gasoline lawn mower are:

Insufficient or complete absence of gasoline. A banal but fairly common reason why the lawn mower does not start. The tank is checked, gasoline is added to the desired volume. Low.quality fuel or incorrectly prepared fuel mixture

In this case, it is very important to study the recommendations and instructions on the issue of the required fuel quality, regarding the using the lawn mowing model. Incorrect position of the air damper. If the damper is closed, and the number of jerks is more than 5, there is a risk that the fuel will flood the candle. Turned off the ignition during launch

The ignition should be turned on immediately after the air damper closes.

The advantage of gasoline lawn mowers

The main competitor of gasoline law mmores are electric lawn mowers. The advantage of gasoline lawn mowers, in relation to electric, is as follows:

  • Do not depend on the availability of an electricity source
  • Have a more powerful engine, which allows you to work on a significant size of the lawn
  • maneuverable, do not have an electric cable that will weave from behind and cling to all obstacles.
  • A gasoline lawn mower can be cut even ordinary, more rigid grass
  • Cheaper services (although they break more often)

Despite this, gasoline lawnmands have several significant disadvantages, namely:

  • Create a noise
  • Suggest additional material costs for combustible materials (fuel and lubricants)
  • Ejecting harmful exhausts into the atmosphere
  • often requires repair and maintenance
  • The design of the engine is built in such a way that when the gasoline lawn mower on the hills is cooler than 25 o, the oil stops entering the lubrication channels of the rubbing parts, as a result of which the lawn mower may break.

Simple instructions for replacing oil in the Briggs Stratton engine or another manufacturer engine.

Before any actions for maintenance of the lawn mower, disconnect the wire leading to the spark plug.

Pump gasoline from the tank with manual pomp. This will not allow gasoline to spill onto the lawn mower and prevent a fire that can start from the spark plug. The damaged candle wire or a candle itself can cause the fire spilled on the base of the fuel mower.

What Happens To An Engine Without Oil?

Find the oil plug under the base of the lawn mower. Most of them are square and fit for a wiper head by 10 mm. It can also be just a traffic jam or bolt.

Blind or hold the lawn mower while you loosen the oil cork with a wrench. Do not forget to substitute a container for drained oil under the base of the mowing.

After the last drop of oil leaks, return the oil plug or bolt to place, but do not tighten or seal yet. With the help of a funnel, pour the drained oil into a bottle or any other container suitable for sending it for processing. Local utilities must carry out such processing.

After the cork is closed and sealed, prepare new oil to pour it through the filling hole to the desired level. In some lawn mowers, the filling hole is located on top, where the oil probe is located, in others it is below on the base near the engine. The described lawn mower does not have an oil probe. it must be poured with oil through the oil cover almost to the neck. Use standard engine oil 10W30 or 5W30.

Check that the oil cover is worn on the pouring hole and then fill the gas tank and set the wire on the candle.

Tools and materials

You may need a set of tools:

  • Oil Container container;
  • clean, dry rags, napkins or towels;
  • end key with the corresponding nest;
  • empty plastic containers (household with lids);
  • engine oil;
  • set of wrenches;
  • trumpet;
  • sling syringe;
  • siphon.

Removing old oil

Extracting old lubrication is one of the most important stages of the process. To make sure you remove a large amount of old oil, you can use three methods.

  • Use a siphon. Insert one end of the tube into the hole for the probe, to measure the oil level until it reaches the bottom of the oil tank. Place the other end of the siphon in a constructively strong container that you will specially use for this and future change of grease. Finally, place wooden blocks or other durable material under the wheel of the mowing on the opposite side of the hole for filling. In the lawn mower under the slope, it is easier to remove almost all the oil.
  • Remove the oil cork. Depending on the type of gasoline braid, you can remove the oil cork to drain the old grease. Contact the user’s leadership to determine the location of your drain plug and make sure that you have an end wrench of a suitable size for work. By installing the wrench on the plug, remove it. When the oil is completely dragging, you can replace the cork.
  • Use such a special device as a syringe for pumping and filling the oil tank. This is very convenient when the hole of the tank is too narrow, and at the same time it is inconvenient or impossible to fill the new oil from the bottle. The syringe can easily pass through the hole to pump out the old waste oil.
  • Tilt method. If you do not have access to a tank with butter, you can drain it by tilting the lawn mower to one side. When tilting the lawn mower, set the lid of the flood neck on the container that you use to collect the waste oil. After the correct location, remove the lid of the flood neck and let the clock completely drain. Using this method, you should know exactly what fuel level is in a lawn mower. It is also important to note where the air filter is located, so as not to pollute it with drain oil.

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 the 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

How to put a knife for a lawn mower in order?

A person can immediately after buying a device to purchase interchangeable blades, or may sharpen the existing knife. In any case, after the part of the part, it must be removed.

First you should turn off the electric device from the power and put it on the side. As for the gasoline unit, then everything is somewhat more complicated.

  • Remove the tank for collecting grass;
  • Gently drain the oil and gasoline in different containers;
  • Turn off the spark plugs;
  • Put the mower sideways.
  • It is necessary to fix the blade with a log or board so as not to cut in the process;
  • Often the blades are attached on two bolts or one, but large, placed in the center. The end or the united key will be an excellent assistant;
  • Unscrew the bolts counterclockwise, since the right thread is standard;
  • If the factory tightening has grown and is held very tightly, you can use a special liquid key WD-40.

There are also such moments when the adapters of the knife need to be replaced, which connect the cutting element with the engine

It is important to understand here that each manufacturer complements the products with certain features, therefore, for example, the specified part from the AL-Co mower cannot be used for MTD

Taking advantage of the tips indicated in the title video, each owner of the “Garden Assistant” can find out the methods that allow you to create an adapter with your own hands using basic details and tools.

Step 3

Remove the pipe of the oil probe or drain plug on old models. Turn the lawn mower to the side to drain the water in new versions. Place the pallet under the lawn mower and remove the drain plug using the end key for old models without a tube to measure oil level. Give me a click for a few minutes. Turn the fork back.

Put on the working gloves and take the lawn mowing blade. Do not take a pointed part. Hold the blade by removing the central screw using the end key. Click the wooden block between the blade and the deck if the bolt is really stuck and turn the bolt to free it. If it still does not budge, apply a liquid wrench or similar penetrating oil around the blade bolt and let it absorb for 10 minutes before loosening.

Step 4

Remove all contaminants from under the deck. Lubricate all cable connections and inspect the wiring for damage. Use the island to repair the bare wires or, if necessary, solder them in place.

Place the new engine on the deck. Do not forget to turn the engine from the holes under the bolts a little and attach the self.propelled drive shaft to the belt or gears before fixing the engine with bolts. Screw the engine to the deck. Install a self.propelled drive lid in place.

Step 3

Loosen the lid on the drain pipe using a divorce key. Remove the lid to let the old glow drain from the engine of the lawn mower into the container on the ground. Or, on some types of braids, turn the valve cover at the end of the drain pipe to allow the click of mowing mowing from the engine.

Give enough time so that as many old engine oil as possible merges from the mowing. Install the lid on the pipe for draining the oil and fix it with a divorce key or turn the drain valve to close the drain pipe.

Remove the probe from the pipe for filling the oil.

Tilt the lawn mower in the direction of the container, until the oil begins to flow out of the upper part of the oilfield tube into the container. Tipping off the lawn mower so that the carburetor is located below, lead to flooding of the carburetor, which can damage the engine.

Keep the lawn mower and let it drain as many old oil as possible. After draining the old oil, lower the mower to the ground.

Fuel replacement in a trimmer with a two.stroke engine

The refueling of the fuel tank of a two.stroke engine (most often the trimmers for grass are equipped with such), and for those who do this for the first time, it is important to understand the procedure for action. We have already said about the significance of compliance with the clear proportions specified in the instructions. Any deviations lead to a reduction in the motor resource. If the oil is not enough, this will lead to lubrication insufficiency and rapid wear of parts. If you add more than it relies, it does not have time to burn, and a plaque forms inside, which also adversely affects the operation of the engine.

The process of replacing the gasoline mixture itself is not complicated.

  • Take a measured container for gasoline and a large syringe without a needle to measure the oil. You can use a special canister for mixing. with separate containers for gasoline and oil with marks for accurate dosage and a convenient nose for refueling.
  • If you have a regular measured container, pour the required amount of oil into it, add half a portion of gasoline to it and mix well. Only then pour the remaining gasoline and mix again. The mixture is ready.
  • Make sure that there is no old fuel in the tank. Pour new, close the lid tightly.

Remember that you can not make a gas.powder mixture with a large margin: with prolonged storage, it loses its properties. It is important to follow the cleanliness of the container in which you mix gasoline and oil.

Oil replacement in a lawn mower with a four.stroke engine

Oil replacement in a lawn mower with a four.stroke engine is performed in a few steps.

  • Get the lawn mower and let the engine work for 10-15 minutes. The oil will warm up during this time and will merge better.
  • Drown out the engine, unscrew the plug plug on the catheter.
  • Turn the lawn mowed to the side from the side of the drain of the oil tank we need.
  • Drain the spent oil into the prepared container, it must be disposed of. Close the lid of the drain hole and place the lawn mower on all 4 wheels on a flat surface.
  • Open the lid of the oil.packed neck. Using the probe, check that the oil is merged (a slight residue is usually still present).
  • Pour fresh oil (if you do not remember the volume, roll first with the instructions), check the level of the pike. Close the lid tightly. The lawn mower is ready for work.

The more attention we pay the technique, the longer it will last. No matter how simple at first glance the device is, there are requirements and recommendations, the observance of which will extend the eyelids of garden assistants, and their operation will not cause inconvenience. So that the garden inventory lives for a long time and does not require the intervention of the masters of the service, it must be correctly used and regularly qualified to serve. Published by
