With what and how to lubricate the gearbox of trimmer for grass? How to choose and apply the correct lubricant
Gearbox for brushcutters Buying any machine is sort of a lottery, but a lot also depends on the gardener. In caring hands and Chinese samples are long-lasting and do not let their owners down at the wrong time. And if you forget to timely lubricate the gearbox of brushcutters, not clean the filters, use cheap low-quality gasoline, then the garden equipment from the most famous brands will become a headache.
Lubricating the gearbox of a brushcutter is one of the most important elements in the maintenance of petrol grass trimmers, which must be done directly by the user.
Time and order of gearbox preventive maintenance
I recommend to preventive maintenance of a new petrol grass trimmer immediately after purchase by adding oil to the gearbox. Despite the high cost of garden equipment, some manufacturers save money and put only minimal amounts of lubricant on the run-in period.
How often should you lubricate the gearbox of a brushcutter?
Often preventive inspection of the transmission with the addition of liquid grease is done once a year at the beginning or end of the season. If you don’t use your petrol grass trimmer for professional cutting, it is enough.
If you do a lot of mowing, you should lubricate the gearbox of your brushcutter every 20 to 50 hours. If the operating conditions of garden equipment are hard, for example, mowing a large field at a time, and the mower has no time to cool down, or cheap lubricants are used, then the lubricant should be checked and added every 20 hours of work.
Indirect indications that the gearbox needs to be lubricated are overheating or increased noisiness of the unit.
I also recommend to replace the lubricant completely, with disassembly and washing of the unit, if you buy a second-hand gasoline grass trimmer.

Variety of greases for garden equipment
According to the instructions, you should use a special gear lubricant to lubricate bevel gears. As a rule, manufacturers of garden equipment produce and recommend the chemistry of their brand, as the most adapted to their devices.
At the same time, to reduce the cost of operation of garden equipment and increase the attractiveness of the brand of automotive chemicals, lubricants for garden equipment are usually made multifunctional. It is intended not only for lubricating the gears of gasoline trimmers, but also for treating the hoses, gears and gearboxes of any garden equipment and mechanical devices operating under high loads.
This gear lubricant is sold in easy-to-use and easy-to-store tubes.
Even if the specialized gear lubricant is almost completely exhausted during operation, additives still create an effective lubricating protective film on the surface of the gears.
It should be noted that many brushcutter owners on the expanses of the former CIS countries use the usual Lithium-based Lithol-24 or grease for Cables for the gearbox lubrication. It is convenient to fill the gearbox with a 5cc medical syringe.
The undisputed advantage of using Lithium-based grease and Lithium-based lithium grease in the brushcutter transmission is that it reduces operating costs. But there are nuances, because of which broke a spear on the forums of gardeners Internet space. My thoughts on what can be lubricated with lithium-based grease and what not, read the article “Lithol as a gear lubricant brushcutter“.
How to lubricate the gearbox of brushcutters, gasoline grass trimmer
Side bolt for 17 on the gearbox of a gasoline grass trimmer
For safety reasons, it is essential that you do all maintenance work on your brushcutter with the spark plug plug boot/plug removed in order to avoid accidental starting. Do not turn the grass trimmer upside down to avoid gasoline leakage.
Unscrew the side screw on the brushcutter gearbox. Depending on the manufacturer of the garden tool, there may be a hexagonal bolt instead of the hexagonal bolt, often a wrench size 17. The thread is normal, unscrew it anticlockwise. Do not loose the washer.
If no grease is visible on the inside face of the screw, then 3 to 4 grams should be added. Turn the gears by hand, changing the direction of rotation, so that the grease is distributed to the gears.
Then replace the screw and tighten it firmly.
Choosing the right engine oil
The oil intended for the 2-stroke engine must meet the following requirements.
- The grease should produce a minimum of ash on combustion. Ideally, it should burn all the oil.
- Grease should have good solubility in petrol and a high degree of purity from the various impurities that can cause clogging of the carburettor’s very narrow channels.
- The oil must have high anti-corrosion, anti-wear and lubricating properties.
There are certain standards of oils intended for 2-stroke engines: TC-W3 and 2T. Lubricants meeting TC-W3 are used for water-cooled engines (boat engines, jet skis). 2T oil is used as a gasoline additive for air-cooled two-stroke engines (lawnmowers, mopeds, chainsaws, etc.).д.).
Oils may be green, red or blue. This is done so that their presence in gasoline can be easily detected.
When using low-quality lubricant the entire engine piston group can fail due to fouling under the piston rings. As a result, they will not be able to compress and scoring will occur on the cylinder walls. Also, incorrect lubrication of the crank bearings can lead to overheating and eventually to seizure. Important: it is forbidden to use diesel oil to prepare fuel mixture, because it does not meet any of the above-mentioned parameters.
Gasoline for mixing
The requirements to gasoline for the mixture are very high, because it is the base of the mixture.к. it is the base of the mixture. The first thing you should not do is look for places where you can buy cheaper fuel (gas stations with no name, etc.).д.), as in the end all the seeming savings of several tens may be eaten by a costly engine repair, put out of operation by low-quality fuel.
And when you use cheap gasoline that has a lower octane rating, it puts more pressure on the engine. Its wear and tear is much faster, the resource is reduced, and, not in a one-to-one ratio, but much more
The second thing to remember is that it is important to use only fresh gasoline for the base of the mixture. Many people have fuel stocks in their country houses or garages and leave them there for up to six months. When fuel evaporates, it reacts chemically with the surface of the canister (especially plastic), thus acquiring new, not at all useful for an internal combustion engine. If the gasoline was standing in a canister for a month and a half, it is better to pour it into a fuel tank where, mixed with the total volume of fresher gasoline, it will not cause any damage to the car engine. Two-stroke engines are more sensitive in this regard. That’s why manufacturers recommend to use only top quality fuel.
As for the octane number, there are still debates among experts about what kind of gasoline to fill in the trimmer for grass. Most manufacturers recommend pouring only high-octane 92 gasoline into the fuel system. True, there is one small caveat, quite often the wording “not lower than 92nd” is specified in the instruction, which leaves room for speculation, what kind of gasoline to use.
Certainly, the efficiency (efficiency coefficient) of the 95-th gasoline is somewhat higher than the 92-nd one. The latter, in its turn, is a successor of Soviet 80-grade, which was used by many machines. But having a higher energy efficiency, the 95th engine also has some peculiarities. For example, it is more suitable for modern car models, while the internal combustion engines installed in garden equipment are far from any constructive innovations, their structure remains practically unchanged for decades. For the two-stroke gasoline engine installed in most modern trimmers, it will be quite sufficient to fill up with 92-grade gasoline purchased from a trusted gasoline network.
It is best to look for options without additives labeled “eco”, “ecto”, t.к. You need a clean gasoline base to work properly. The additives in the mixture will provide the oil.
Whether you need 95 gasoline for optimal performance is more of a philosophical question, and there is no specific answer. Suffice it to remember that in the tolerances and recommendations it is found quite rarely, and this already says a lot. over, it is usually filled at your own risk, wishing to improve the performance. If for the sake of experiment you want to change the 92 gasoline to the 95, it is important to remember the consequences in the form of increased wear, unstable operation of the power unit and failure of its individual components. Of course, none of the above may happen, but the probability, in the case of out-of-tolerance, is extremely high.
Suitable oil and gasoline for filling the 2-stroke engine
Two-stroke gasoline engines are designed to run on a fuel mixture. The oil in the lawnmower is not changed separately. it is proportionally mixed with gasoline. Only a properly prepared fuel mixture should be poured into the engine system.
Cheap 2-Stroke Oil Better? Let’s find out! Amsoil vs SuperTech 2-Cycle Oil.
You should not use oil following the principle “the higher its price is, the better it is for the mechanism operation”. Suitable for 2-stroke ICE varieties of oil compositions according to the way they are obtained are divided into such groups:
The lubricating properties of the material, its ability to remain a fluid at a lower temperature without greatly increasing its viscosity, depend on the basis. The grease composition includes about 5-15% of a variety of additives. They are intended to increase the practical effectiveness of the product used. Additives allow:
- to slow down the corrosion process of metal surfaces, connected with the oxidation-reduction reactions;
- to increase the thermal resistance of the parts;
- stabilize the viscosity index of the substance at the same level when temperatures change within a certain range.
Lawn mower manufacturers indicate in the manuals the lubricant brand that is optimal for the operating machine. If it is difficult to obtain, it is possible to change the oil to a similar composition intended for 2-stroke engines. The viscosity level should always correspond to the value recommended by the engine manufacturer.
Gasoline is the main volumetric component of the prepared fuel mixture. Its grade must correspond to the one recommended in the lawnmower user manual. The octane number of gasoline depends on its combustion time: the higher the number, the longer the fuel burns.
If you use a higher brand of gasoline than recommended, the two-stroke combustion engine will fail faster.
Recommendations for storing the ready-to-use fuel mixture for the grass trimmer
After filling up the grass trimmer, many people put off the remaining mixture in the bottle until the next time. Sometimes this next time comes not soon, and stretches to the next year. It is impossible to store the ready-to-use mixture for such a long time because the oil decomposes. After the mixture is ready, it should be used within 1-2 weeks. In addition, you can not also store the tool for a long time with the fuel mixture poured into the tank, as the effect will be similar. To prevent unforeseen circumstances, it is advisable to consider the following recommendations for storing a ready mix of gasoline and oil:
- Use only as much fuel mix as you need. If you don’t know how much fuel to use, then it is better to prepare less
- If the fuel mixture remains in the tank of the grass trimmer (when the tool is hidden until the next season), it must be completely used up or drained
- Stir the mixture thoroughly before pouring it into the tank
- Store the ready mixture in a tightly screwed container, and in a place limited to sunlight
If you follow all the recommendations, the life of the grass trimmer will be at least as long as the instructions. The use of quality consumables paired with adherence to the recommendations for preparing the mixture into the grass trimmer, will result in a long and efficient service of the gasoline tool.
Oil for brushcutters. how to choose and what proportions to use
Many of you have in the household gasoline tools, for example, in a private home can not do without a chainsaw. You know, making firewood for the winter, comes in handy at construction and repair, and in general, it is a very useful tool. If your country house also has a decent-sized plot, then the grass trimmer or lawn mower, which also run on gasoline, is simply necessary to deal with grass.
Of course, you can buy them and electric, but not everyone likes to pull a 30-meter extension cord to mow the area overgrown with grass to the knee. That’s why most people prefer to work with petrol-powered tools. As you know, you need to add to your gasoline a special oil for two-stroke engines. Here we are going to talk about it, because it is a very important aspect, if you will not add oil and add it in wrong proportions, then your engine will “crack” very quickly and your way will be to the service center. To avoid all these problems, it’s best to use the correct oil in the correct proportions.
The most popular for chain saws, brush cutters and trimmers is the well-known STIHL brand. It is sold in two packages. 1 liter and 100 ml. A liter bottle is good for those who do a lot of work, but a small bottle is enough for “just one cut”. The capacity of 1 liter costs 250, and for 10 ml. 60. If you take a large one, it saves a lot of money.
You add oil to petrol in the ratio of 1 to 50, so for example you add 100 ml for 5 liters of petrol. As you see, a small bottle is perfect for getting 5 liters of gasoline mix for your chain saw or weed trimmer. The large bottle has special markings on the side, by which you can tell how much oil you have poured out of the bottle. If you bought a big 1 liter bottle, you can buy a 20ml syringe at the drugstore. Very convenient. 1 syringe of oil for 1 liter of gasoline.
We advise you to use a brand-name oil for your machine: it is the ideal solution, because it has been developed and tested specifically for STIHL power tools. I should note that Stihl has its own brands, such as VIKING (popular models of gasoline trimmers). For them also use Stiele oil and there will be no problems at all.
If you have more petrol mix than you can use, it is best to store the rest in a metal canister or glass container. Never store the mixture in a plastic bottle. Of course, if you use up the leftovers in a couple or three days, you can also pour the rest of the mixture into a plastic canister, but if the mixture will be stored for a long time, then either a canister or a glass container. The thing is that the gasoline mixture corrodes the plastic bottle, microscopic deposits of plastic appear in the mixture and this is very bad for the engine. Keep this in mind if you want your tool to run long and without problems.
The second most popular oil brand is the notorious Hooksvarna. Of course, if you put it this way, more people use STIHL chainsaws, at least all my friends and their friends use them exclusively in their work.
But there are those who cherish Husqvarna tools and I understand them, because I personally do not see much difference between Husqvarna and Stihl, both tools are of very high quality. But I’ve seen satisfied Husqvarna chain saw owners. they say the saws are great. I have not cut any saws myself but I always listen to what people say. So, if you have gasoline Husqvarna tool, then it will be better to use a special brand oil for it. But nothing bad happens if you dilute the gasoline with Stihl. But since the manufacturer recommends using only its products, so we will do it.
On sale you can find a liter capacity. The bottle is black, stylish, with the same markings on the side as Stihl’s (to know how much oil has been poured out of the bottle). Seems to me the quality is exactly the same. It’s 270, a little bit more expensive.
Both oils are of high quality, cost about the same, and are diluted 1:50 each. So feel free to buy any, of course, it is better to take the oil of the brand that you have a tool. then everything will be perfect, just as the manufacturer advises. Good luck with sawing, mowing the grass and let your power tool work for a long time without failures.

Oil for brushcuts. how to choose, in what proportions to dilute
Many of you have in the household petrol power tools, for example, in a private home can not do without a chainsaw. You know, making firewood for the winter, comes in handy at construction and repair, and in general, it is a very useful tool. If the country house also has a decent-sized plot, then the grass trimmer or lawn mower, which also work on gasoline, is simply needed to fight the grass.
Of course, you can also buy electric ones, but not everyone likes to pull a 30-meter extension cord to mow a knee-deep patch of grass. That’s why most people prefer to work with a gasoline tool. As you know you need to add to the gasoline a special oil for two-stroke engines. That’s what we’re going to talk about, because this is a very important aspect, if you don’t add oil and add in wrong proportions, then your engine will “croak” very quickly and your way will be to the service center. To avoid all these troubles, you should add only quality oil in the right proportions.
The most popular for chainsaws, brush cutters and trimmers are products of the famous company STIHL. It is sold in two packages. 1 liter and 100 ml. A liter bottle is good for those who do a lot of work, but a small bottle is enough for “one cut”. A 1 liter container costs 250 and a 10 ml container costs 60. If you take the big one, the savings are obvious.
Add the oil to the petrol at a ratio of 1 to 50, which means you add 100 ml for every 5 liters of petrol. As you can see, the small bottle is great for getting 5 liters of gasoline mixture to fill a chainsaw or grass trimmer. The large bottle has special marks on the side, by which you can determine how much oil you have poured out of the bottle. If you bought a large 1000 ml bottle, go to the drugstore and buy a 20 ml syringe. Very convenient. 1 syringe of oil per 1 liter of gasoline.
We recommend that you use original STIHL oil for your machine, because this is the ideal solution as it has been developed and tested specifically for STIHL power tools. Note that Stihl has its own brands, such as VIKING (popular models of gasoline trimmers). They also use Stihl oil and there will be no problems at all.
If you have put more petrol in the mix than you can use, it is best to keep the remainder in a metal canister or glass container. Never store the mixture in a plastic bottle. Of course, if you use up the leftovers in a couple of days, you can pour the rest of the mixture into a plastic bottle, but if the mixture will be stored for a long time, then either a canister or a glass container. The whole point is that the gasoline mixture corrodes the plastic bottle, there are microscopic deposits of plastic in the mixture and this is very bad for the engine. Keep this in mind if you want your tool to work long and without problems.
The second most popular oil brand is the notorious Hooksvarna. Of course, when you put it this way, more people use STIHL chainsaws, at least all my friends and their friends use them in their work.
But there are those who cherish Husqvarna tools and I understand them, because I personally do not see a big difference between Husqvarna and Stihl, and both tools are of very high quality. But I have seen happy owners of Husqvarna chainsaws. they say the saws are awesome. I have not sawed myself, however, to the opinion of people always listen. So if you have a Husqvarna power tool, it would be better to use a special brand oil. But nothing bad will happen if you dilute the gasoline with Stihl. But since the manufacturer recommends using only his products, we will do so.
On sale you can find a liter capacity. Black stylish bottle, same markings on the side as Stihl has (to know how much oil has been poured out of the bottle). Looks to me like absolutely identical quality. It’s 270, a little more expensive.
Both oils are of high quality, cost about the same, each diluted in the ratio of 1 to 50. So feel free to buy any oil of course it’s better to use the brand you have your tool in. then everything will be perfect, just like the manufacturer advises. Good luck with sawing, mowing, and may your power tool work for a long time without failures.
General recommendations for lawnmower oil selection
Based on the above engine design features, it is best to use a special lawnmower oil for lubrication, and it must be suitable for the temperature conditions in which the unit will be used. SAE 30 specialized lubricants are regarded as optimum. It is used at temperatures above 5 degrees.
If special is not available, you can use automotive grade grease:
These lubricants are also designed mainly for positive ambient temperatures and a maximum value above 35 degrees.
What 2-Stroke oil should you use?
By type of grease. mineral and semi-synthetic are acceptable. Fully synthetic will be too expensive. API performance level. “SF”, “SG”, “SH”, “SJ” and higher. For four-stroke gardening equipment engines the label should say “4T”.
How to mix
If you do not have a special measuring canister with graduations, which are included with each noteworthy trimmer for the grass, or such a container is lost, then use any suitable container. Glass or metal containers are best. You can also use plastic, but you need to choose a bottle with stiff walls.
Container capacity should be a multiple of 1 liter. You can also take a 1.5 liter bottle, but practice shows that it is not very convenient. You also need a syringe, preferably about 20-50 ml. First pour petrol into the container, then add exactly the right quantity of oil (by volume). Do not change the procedure.
If you have a “pre mix” oil the bottle or canister must be covered and turned upside down several times and shaken vigorously. If the oil is “self-mixed” it will dissolve on its own. The sharpening mixture must be used within one day. If you know how much fuel a grass trimmer uses for a certain amount of work (or time), it is not difficult to calculate the amount of mix. Otherwise, dilute new fuel before each filling so that a minimum amount is left over until the end of the work.
