How to mow grass with blades of grass?

Mowers are equipped with blades that consist of mutually sharpened blades. The number of blades depends on the type of knife:

Two-blade blade has two blades and is designed for household brushcutters. It is used to mow young grass.

Three-blade knife is equipped with three long blades. It is a universal set for lawn and garden maintenance.

The four-blade blade has short blades and a large base. It is used to cut the grass, which is used to feed the livestock.

Varieties of material

Oil. the name is rather arbitrary. It is an oil base with a variety of additives. Without them, its lubricating qualities are not so great.

The base is divided into two types according to its origin:

  • Mineral. obtained by refining oil. Its properties are significantly dependent on the composition of the starting material and are not stable, which is why a large number of different additives are added to the mixture. Despite their action, it is recommended to replace the mineral material as often as possible;
  • synthetic. produced by directed synthesis. The properties of the mixture are predetermined, are characterized by stability. synthetics last longer and need to be replaced less often.

Additives added to the base, give the ready mix various additional properties:

  • antioxidants. prolong the “life” of the mixture itself;
  • Corrosion inhibitors. protect the engine from rusting;
  • anti-wear additives. reduce wear of parts;
  • thorny modifiers and so on.

Different additives are added to synthetic and mineral bases to obtain the same properties, and in different percentages. That is why it is forbidden to mix the blends under any circumstances.

much, needed, gasoline, mower

To prepare fuel mixture, use clean, fresh, unleaded gasoline with octane number no lower than 92. Strictly follow the instructions for mixing gasoline and oil. Use a special container to mix gasoline and oil. Do not mix petrol and oil directly in the fuel tank.


At the beginning of work with the tool there is always the question of how much oil to add to gasoline for a chainsaw or grass trimmer. It is important to remember that for two-stroke engines the ratio is 1:50, i.e. е. 100 ml of oil for every 5 litres of fuel.

What is the ratio between petrol and oil for a lawnmower?

How to dilute petrol with oil for a lawn mower, what kind of petrol do you need??

You have to use only AI 92 gasoline for your lawnmower.

Ratio is 1 liter of petrol and 40 grams of oil for two-stroke engines.

First mix petrol and oil and pour it into the tank.

If you do not mix petrol with oil, but add petrol and oil first, the lawn mower will not work and the piston will burn out.

For the preparation of the fuel mixture for the lawnmower should have at least gasoline AI92, secondly a special synthetic oil for two-stroke engines and thirdly a clean container for mixing. Many people just pour petrol into the tank first, and then the oil, and shake the mower a bit. As a rule, the necessary ratio of gasoline and oil is specified in the data sheet, but if it is lost, you can mix the components in the proportion of 1:40 and you will not make a mistake. So you need about 25 grams of oil for every liter of gasoline. It may be just the volume of a standard cap from a container of oil. By the way extra little increases the smokiness of the mixture during operation, and hence the soot.

Usually, manufacturers write in the instructions that gasoline must have an octane rating of at least 90. As for the proportion of oil and gasoline, again, you need to look at the instructions. For one saw 1 to 30, for others. For example, for a Husqvarna chainsaw, the octane rating is 1 to 40, but for a Husqvarna chainsaw, it is 1 to 50.

Usually, when you buy a lawnmower comes with an instruction manual, which clearly describes the requirements for fuel. But the instructions are not always followed. In order to prolong the life of the lawnmower, you need to add oil to the gasoline. Usually it is done in the ratio of 1 to 40, that is, for 40 liters of gasoline take 1 liter of oil. If you cut the amount of gasoline to 1 liter, you need 25 ml of oil.

Before you fill up your mower, this mix needs to be well mixed in a separate canister, and only then pour it into the gas tank.

1 in 40, I know how, a liter of gasoline40 ml of oil (you have to drink less).The grasshopper worked for 5 years. and even with last year’s fuel not drained.And then, bingo. You need 25ml.Diluted, poured, started, stalled. and it won’t start any more.Changed the carburetor. all in one.Funny. I already bought a new one.I wanted a two-stroke.But the AL-KO is lying dormant.

Dilute in the proportion for one liter of gasoline 50 ml of oil for two-track internal combustion engines. you can’t go wrong.

It’s better to use A.I.93 or A.I.95.

Well, the exact proportion and brand of gasoline should be specified in the passport that came with the product

In chain saws, a 2-stroke engine is usually used. Accordingly you should use the fuel mixture on which the 2-stroke engine runs.

Since the engine has no lubrication system, oil is added to the fuel. If no oil is added to the fuel, the engine fails very quickly because the rubbing parts are running dry and overheating. Pistons, piston rings and cylinder are the first to suffer.

Recently, almost all manufacturers recommend using gasoline with an octane rating of at least 92 with 2-stroke oil in the ratio of 40:1.

If the engine is new or overhauled, some more oil may be added for the running-in period (25:1). In any case, if you don’t know the manufacturer’s recommendations, you’d better have a look at the label of the oil can. If it is a question of changing the proportion, it is better to give more oil. The risk of engine failure will be minimal.

Get the manual for the lawnmower, it’s usually the booklet you bought the mower with. It will definitely say what are the requirements for gasoline. Normally you have to use a 1:40 ratio, although 1:30 is possible. That is 1 part oil and 40 parts gasoline. The oil packages also indicate the ratio. We buy 92 gasoline, mix it with oil in a separate canister, and then fill the mower and chainsaw with this mixture.

My father dilutes gasoline in a one and a half liter plastic bottle for the mower.

Gas found in Oil Lawn tractor Edition

He pours the gasoline into the bottle not to the edge, but as the water was originally poured there. Then pours half a capful of oil in it. There’s 100 grams in this graduated shot glass, so it pours 50 grams of oil into 1.5 liters of 95-grade gasoline.

I dilute the gasoline and oil for the gasoline mower in a three-liter can.

I pour 1 capful of 93 or 95 grams of oil per liter of gasoline (the cap from the oil bottle).

That’s what my dad taught me, and he has been working with engines for over 40 years.

My mower is 7 years old and has never (three times) broken down.

Most often, for two-stroke engines in gasoline mowers use gasoline AI-92, and the ratio of oil to gasoline 1k40. But if you’re not sure, you can try 1k30. And you should see how your mower works and correct it in one way or another.

Oil selection

The first document to consult when choosing an oil brand is the passport of your tool. The manufacturer not only specifies the characteristics of the lubricant there, but also offers specific brands and trade names.

If you can not refer to the manual, it is recommended to use only two choices of lubricants:

  • Semi-synthetic motor oils, which have a medium cost (slightly higher than mineral oils). Produced by distillation of high-molecular oil products, produce a little smoke and have a good performance in protecting the structural components of the engine. Can be used in both domestic and foreign trimmers;
  • Synthetic motor oils, which usually have the highest value in the range. This is the most reliable engine wear protection, compatible with any power pack.

In addition to the basic type of oil, it will be useful to still read its letter marking, in order to choose a compatible type according to the parameters. According to the European API classification, there are the following designations for two-stroke engines:

  • TA. oil for small power units (no more than 50 cc). see.), which makes it possible to recommend this particular type for motorized machinery;
  • TV. grease for larger engines with displacement in the range of 50 to 200 cc. cm. It is allowed to use such for brushcuts;
  • TC. engine oil for serious equipment (motorcycles, snowmobiles, scooters), which involves mixing with gasoline;
  • TD. lubricant for flooding vehicles.

Will a 4-cycle lawnmower run on 2-cycle gas/oil mix?

There is also a classification of the Japanese organization JASO, which in assigning the labeling was guided by the level of smoke emission. It is necessary to decipher these designations as well:

  • FA. on combustion, smoke emissions are negligible and hardly visible to the naked eye. For countries with strict emission requirements;
  • FB. slightly more visible smoke of white color, but more than in FA;
  • FC. transparent smoke, which is not visible at a glance;
  • FD. oils which do not emit smoke and are used for refuelling water-borne vehicles.

You can also see the labels on the canisters “Self MIX” and “Pre MIX. FA. the first option means that after adding to fuel, the mixture does not need to be stirred forcibly. Second option. the gasoline-oil mixture must necessarily be stirred by hand.

Using these three labeling options, it is easy to select the type and brand of grease needed. The only question remains the ranking of manufacturers. Here, the most famous brands that produce only high-quality fuel and lubricants:

  • SHTIL is a popular manufacturer of gasoline equipment and consumable components for them;
  • Shell Helix Ultra. used for both cars and small motor vehicles;
  • Motul is a recognized leader in the production of lubricants;
  • Lukoil. a brand of domestic production, which is not inferior in quality to foreign counterparts.

We recommend that you do not skimp on motor oil, because the smooth operation of the power unit depends on it.

If you have bought a trimmer for grass, and the instructions in the kit are only in English, do not despair. In this article you will find the answer to the burning question. how to properly fuel a brushcutter with gasoline. First we get acquainted with the construction of the engine gasoline trimmer. Engines for gardening machinery are usually two-stroke. This means that the equipment responds faster when the throttle handle is pressed. The design of the two-stroke engine is simpler, and to fill the gasoline must be mixed with oil. Gasoline and oil are filled separately in a four-stroke engine. Grass trimmers with a four-stroke engine are rare, most often it is a professional brushcutter.

How to fill a petrol trimmer with a two-stroke engine?

1) To fill the grass trimmer clean gasoline not lower than AI-92, and high-quality oil. Oil should be special for air-cooled two-stroke engines. Confuse it with oil for water-cooled engines is unacceptable, the use of the latter type of oil can lead to grass trimmer work with insufficient cooling, and to breakdown. Grass trimmer oil must be JASO or API approved.

2) It is necessary to fill the grass trimmer’s tank with a fresh mixture of gasoline and oil. The mixture should not be stored for more than 3 months. Mixing ratio of oil and gasoline: 1 part oil, 40 part gasoline. Do not “by eye” mix the liquids directly in the fuel tank. It is necessary to do it in a special container with measuring divisions. If this rule is not observed, the operation of the engine may become unstable and the engine may fail.

3) Mixing process: a part of oil is poured into a measuring jug, then 20 parts of petrol is added and mixed carefully. Then 20 parts of petrol are added to the mixture and mixed again.

If you add too little oil to the engine, it will result in insufficient lubrication, scoring on pistons and cylinder bore, damage to the piston group. If, on the contrary, a lot of oil is added, the engine can get caked (deposits appear on the internal parts of the engine).

4) Fill the fuel tank. put the lid on the tank and fill the tank up to the required volume. Screw the lid on tightly. The engine is ready to run. When starting, make sure the fuel mix fills the primer bulb.

How to fill a gasoline trimmer with a four stroke engine?

1) The gasoline used is still the same, no lower than Ai-92, clean and fresh (stored for no more than 60 days outside the gas station). choose a special oil, suitable for four-stroke engines, with classification SAE30 and API. It is by no means necessary to mix oil and petrol!

2) Fill the engine crankcase with oil. Usually not more than 90 ml for the first filling. When you run out of gas, there may be oil left over. If there is less than half left, oil should be added to the crankcase.

3) Fill the tank with gasoline, keeping the cap up. Do not overfill the tank, otherwise it will overflow into the intake pipe and cause engine damage or gasoline ignition. Screw on fuel cap. The engine is ready to run!

A few last tips. First, you can buy engine oil from us at Secondly, when charging the engine trimmer with gasoline must comply with safety measures: do not spill gasoline, and if it spills, wipe it off immediately; include gasoline trimmer, only moving away from the container with gasoline or fuel mixture for at least 10 meters. Thirdly, if you intend not to use your trimmer for a long time, the remaining gasoline should be drained or used up to the end.

How much oil per liter of gasoline is needed for a lawn mower or chainsaw

All two-stroke engines run on a fuel mixture of gasoline and oil. Fuel enters the cylinder, burns there, creating a working force on the piston, and the part of the mixture that has not had time to ignite, lubricates the moving parts of the piston group.

When drawing up a fuel mixture for a lawnmower or chainsaw, you need to calculate how much oil you need per liter of gasoline, based not only on the standard proportion, but also on what brand of gasoline and oil is used. In the case of two-stroke motors, this is very important.

For trimmers, a special two-stroke oil is produced, which should be marked “2T” on the package. It is strictly forbidden to use motor oil, especially transmission oil. Two-stroke oil is produced in three types:

See also  What oil to mix with gasoline for grass trimmer

It all depends on what substances make up the base of the oil. Mineral oil is the cheapest and most unreliable. Its use is justified only in household trimmers, which work for 30-60 minutes a day with long breaks. Most brushcutter manufacturers at this level specify that TC-W3 oil is suitable for the engine. This means that you can use mineral, synthetic and semi-synthetic 2T.

For professional-grade brushcutters, it is advisable to buy only the oil brands recommended by the manufacturer. Usually it is semi-synthetic and synthetic with special additives.

Manufacturers mark the oil with letters:

  • ? TA. for two-stroke engines up to 50 cubic centimeters;
  • ? TV. for engines of 50. 200 cc;
  • ? MT. for motorcycle engines, snowmobile engines, etc.д.

If your brushcutter is not specified in the manual, you can use all three. How much oil to add to the fuel of a grass trimmer depends on the brand of the tool and the quality of gasoline. Also there may be letters FA, FB, FC, etc. on the package of oil.д. They show the smoke level. The closer the second letter is to the beginning of alphabet, the more smoke is emitted during combustion. As a rule, high-quality oil has very little. This indicator does not affect the choice of oil.

important than “self mix” and “pre mix” labels. The first word means that the oil dissolves itself, and the container with the second mixture must be shaken several times.

If the manufacturer’s instructions do not specify what gasoline to use, it is necessary to stop at the AI-92. If it is recommended to use AI-95, then do not use other brands of gasoline.

Some users believe that if you add more oil to the fuel mixture than necessary, it will benefit. This is not true. Unburned oil will not be expelled from the engine with the exhaust gases but will settle inside as a carbon deposit. This build-up threatens the integrity of the piston. If you use a mix with too much oil regularly, the weed trimmer will smoke a lot and a drop in power is inevitable.

If there is not enough oil, the grass trimmer will overheat, the piston rings will collapse and the piston will jam. If the oil deficit is insignificant, then the grass trimmer will work for 30. 40% less resource. If the grease is missing more than 20%, the engine will jam after 20 to 30 minutes of intensive work. Every manual to the trimmer provides proportions on how to dilute the fuel mixture. Usually it’s 1:25. 1:40 or 1:50.

00 ml jars

A separate story, these are jars of 100 ml.

Sellers in gasoline stores always confidently state that to prepare a mixture, it is enough to dilute such oil with five liters of gasoline and that’s it, you can go to battle. This is not really true, and we have just checked it, so please be careful and mix correctly.

Relationship between petrol and oil for gasoline and grass trimmer: how much oil to give? How much to dilute with petrol?? How much do you pour per liter of gasoline??

Mowers. Very popular equipment for struggle against heavy vegetation in country houses, in plantations, road and housing and communal services. These devices also have two names. trimmer and lawnmower. These units differ in their engines. The most expensive of them have four-cycle engines, all the others. double-touch. Of course, the latter are the most popular among the population, as they are simpler in design, lighter in weight and considerably cheaper than their four-stroke competitors. But two-stroke models are not user-friendly because the fuel mixture for them needs to be prepared manually, depending on the dosage ratio between petrol and oil.These components are blended automatically in four-stroke counterparts, the gas tank and oil tank should only be filled with the required reagents. Let’s have a look at the correctness of filling two-stroke brushcuts, because it affects how effective and long will be the work of this unit.

Learning the rule of thumb for choosing different brands of lawnmower oil

motor oil is a special composition, consisting of a solvent and additives to reduce friction, create the necessary fluidity and prevent thickening when the temperature drops.

  • Mineral, obtained by distillation of oil;
  • synthetic. by synthesis or processing of natural gas;
  • Semi-synthetic. an improvement of a mineral oil by adding synthetic components.

For safety reasons, the oil is dyed red, blue or green so as not to confuse the products. The range varies in composition, the user should buy the oil marked “for garden equipment” 2T if you need to prepare a mixture for two-stroke engine, 4T for filling in the crankcase.

Synthetic and mineral oils have different bases and must not be mixed. If changing to another oil, the system must be flushed out thoroughly.

The lawnmower oil must be classified as a TC oil for air-cooled engines with a combustion chamber volume of 50-200 cm3. The most important factor in choosing a product is not the price, but its protective properties for the engine of a specific brand. That’s why you buy the recommended oil first and then get an identical one if it is unavailable.

Lawnmower oil quality is determined by the alkali value. Alkali neutralizes oxidation of friction materials, inhibits surface degradation. When oil becomes oxidized it loses its protective properties. A normal oil pH is 8 to 9.

Viscosity is important. That is why there are winter, summer and multigrade oils. Which lawnmower oil to use depends on whether the user will operate the lawnmower at sub-zero temperatures. Summer oils get thick even when they get a little cold. Flash point shows how quickly the oil burns out of the composition. than 225 0 C is optimal.
