How to drain the STIHL lawnmower?
Tilt the deck of the mower and place newspaper and an oil pan or jug under the mower. Use a socket wrench to unscrew the plug counterclockwise and drain the old oil.
engine oil Information on engine oil Use only high-quality 2-stroke engine oil that meets TC class requirements (preferably STIHL 2-stroke engine oil. specially formulated for STIHL engines. for longer engine life).
To check the oil in your lawn mower?
Use unleaded 92 octane gasoline. Never use old or contaminated gasoline or an oil-gasoline mix. Do not let any dirt or water get into the fuel tank.
How to change an oil
It is not just important to choose a quality oil that is right for your machine. You also need to know how to pour it into the lawnmower correctly. The rules are uncomplicated, but mandatory to follow:
- turn the machine on and let the engine idle for a quarter of an hour;
- Remove the cap from the tank and put a container of the right size to collect the used fluid;
- Tilt the mower and drain the used material;
- close the cap and put the machine on as flat ground as possible. After that, you can open the hole at the top;
- Pour in the new operating fluid, following the recommendations of the equipment manufacturer regarding the volume, checking the fluid level conveniently with a dipstick;
- When the fluid has reached the correct volume, the plug can be screwed on.
In most cases you should use around 500 ml of fresh oil to replace the used fluid. This value corresponds to most of the machines that are common in Russia. That is why you should study the instructions before changing the used fluid.
Requirements for lawnmower oil
Engines in small agricultural machinery are not the same as in cars, so the lubrication fluid must be different. Filling the mower with the mixture intended for cars or motorcycles is not allowed: it may cause damage. Even if there are no malfunctions, the lawnmower is likely to start working worse: the fluid not intended for this type of equipment will not be able to cope well with its functions. That’s why they recommend using special oils designed for garden equipment.
lawnmowers and mowers. Cooking the fuel mix. Lawn mower engine oil change
When choosing a means to care for the grass in the garden or dacha, the owner is faced with the choice. what to buy. a lawn mower (electric mower) or a wheel mower. The abundance of information on the Internet and sellers’ advices make a perfect mess in the heads of potential buyers, based not only on experience (including negative), but also on prejudices and outright ignorance.
lawnmowers are only for strong men! (Schwarzenegger type).
A lawn mower is a two-stroke gasoline engine with an output of 1 or 2 liters.с., at one end of the tube. At the other end is a cutting element, a disc or a spool of fishing line. The total weight of this device is several kilograms. And the suspension point is made so that even a fragile girl can handle a lawn mower. Grasshopper is very well balanced.
Fueling two-stroke engines and preparing the fuel mixture is a miracle of alchemy, inaccessible to mere mortals
Two-stroke engines do not just require gasoline but a mixture of gasoline and oil (special for two-stroke engines). This is absolutely not a deficit, oil for two-stroke engines is sold in any auto parts store and in any place where these very lawnmowers are sold Ask the seller and he will lead you to the shelf with these oils. It’s an eye opener to choose from.
And making a gasoline-oil mix is no more complicated than dressing a salad with mayonnaise. As a rule, the oil to gasoline ratio in the mixture ( 1:32. 1:35) is indicated on the mower (or chainsaw). That’s the ratio for mineral oils. It’s hard to find oil for two-stroke engines, except for motorcycle engine oils. For small packaged oils for gardening equipment. practically only synthetic oils. They have a 1:50 ratio (it usually says so on the package). You should follow the recommendations from the oil package!
To prepare fuel mixture you take a fuel canister, for example 5 liters of gasoline and add 100 ml of oil to it. That is all the secret. You will have enough for the whole season. Not enough. repeat the procedure You pour that mixture into the gas tank and no more problems.
You should only buy Husqvarna oil for a Husqvarna lawnmower
Husqvarna doesn’t have its own refineries. That’s a whole other business. So she buys the two-stroke oil from refineries in tanks, fills it up in small cans and tags it “Husqvarna” And she pays the uninformed an extra 2-3 for that tag. Another company, like STIHL, buys the same oil from the same plant and puts a “STIHL” sticker on the bottlesAnd they charge 2-3 bucks for their fools too Any two-stroke oil is good for any two-stroke engine!
Wheeled lawnmowers are only for perfectly level lawns.
No, it doesn’t I used to think so too on my completely unplanned lawn. The wheel mower is very good at bending over the terrain. The only obstacle is anthills that can be removed with a shovel. And uneven terrain is handled very well with a ride-on mower. Especially if it has an adjustable cutting height. You set it to maximum and check your lawn. Where the blade touches the ground, you can also work with the shovel.
The lawn mower with wheels mows more than twice as fast as a hand lawn mower. And it’s no more difficult to steer than a stroller. You just walk and guide it. Especially if it’s a self-propelled mower. Even children can manage it.
Wheeled lawn mowers have a 4-stroke and their maintenance is as complicated as a car.
Wheeled lawn mowers tend to have four-stroke engines. The basic difference between the four-stroke engines and the two-stroke engines is the presence of a crankcase in which there is oil for engine lubrication. For this reason, a 4-stroke engine does not need a fuel mixture of oil and gasoline, but only gasoline in the gas tank. This fact is presented by some dishonest salesmen as an advantage. “there is no need to bother with the fuel mixture preparation”. At the same time they “nicely” omit such a detail as the necessity of at least an annual oil change in the oil sump of a wheeled lawnmower. The procedure is not complicated, much easier than changing the oil in a car, but more complicated than preparing the fuel mix. Generally speaking, the oil in the mower’s crankcase needs to be changed about every 50 hours of operation. The lawnmower does not have an oil filter and therefore does not clean the oil. This is the reason for the frequent oil change regime. On the other hand 50 hours of mower work per season is a very long working hours.
The process of changing the oil in a ride-on lawnmower is simple. Before changing the oil it is desirable to give the lawnmower about 10-15 minutes to work, so the oil would warm up and become more fluid.
Any lawnmower has a special screw that covers the drainage hole from the motor housing. It is usually located under the crankcase filler neck and measuring cup. (marked with an arrow in the photo).
The lawnmower is installed with a slope towards the drain hole, placing a wooden block or a brick under the casing on the opposite side. After that unscrew the screw. plug. So that the oil does not spill on the mower’s cowl, a chute is cut out of a plastic bottle to catch the oil in the container below. It is advisable to drain the gasoline from the gas tank before changing the oil.
After that, the screw-cork is unscrewed and allow the oil to drain by tilting the lawnmower. When the oil has drained out, screw it back in. Fill in fresh oil through the measuring jug. Lawn mowers are usually advised to use 10W40 oil, mineral or semi-synthetic.
The inexperienced owner of a garden machine tends to idolize his new machine to the point of fetishism. He wants to fill it with better gas and more expensive oil. This is a very common mistake and can lead to machinery failure very quickly!
The fact is that this garden equipment is made “in flux,” t.е. The materials used in it are the most common, not special. The clearances in the engines are “assembly line”, nobody lapped anything there. This is why you should never use oil that is thinner than recommended by the manufacturer. It just won’t hold in the gaps between the parts.
How to fix a lawn mower blade?
A person can buy replacement blades immediately after purchasing the device, or he can also sharpen the existing blade. In any case, after blunting the part, it must be removed.
To begin, you should disconnect the electrical device from the power supply and place it on its side. As for the gasoline-powered unit, everything is somewhat more complicated here.
- It is necessary to remove the tank to collect the grass;
- Carefully drain the oil and gasoline into different containers;
- Disconnect the spark plugs;
- Place the mower sideways.
The following steps apply directly to replacing the blade.
- It is necessary to fix the blade with a log or board, so as not to cut yourself in the process;
- Often blades are fixed on two bolts or one, but a large one, placed in the center. A socket wrench or a ring spanner will be a great helper;
- Unscrew the bolts counterclockwise, as the right-hand thread is standard;
- If the factory tightening prikipelala and holds very firmly, you can use a special liquid wrench WD-40.
There are also times when the blade adapters, which connect the cutting element with the engine, need to be replaced. Here it is important to understand that each manufacturer supplements products with certain features, so, for example, the specified part from the AL-KO mower cannot be used for the MTD.
Using the tips listed in the video below, every owner of a “garden helper” can learn the methods that allow you to create an adapter with your own hands using basic parts and tools.
Recommendations for oil selection by specific manufacturers
Lawnmower manufacturers necessarily indicate in their instructions the type that is used in their machines and also the frequency of oil changes, usually in moto-hours. Usually the manufacturers indicate their brand lubricants and it is worth using them if you want to keep the warranty on the equipment. But often manufacturers also indicate general characteristics of the lubricants and then it is possible to choose similar lubricants from the more widely available automotive oils.
Some engine oil manufacturers produce a special series for garden equipment. It may be cheaper, but it requires more frequent changes than the regular one.
The best oil for any engine is the one recommended by the manufacturer. Shell Helix Ultra is world-renowned. Shell has spent 40 years developing new technology to produce synthetic oil from natural gas. Pureplus technology makes it possible to obtain an improved base oil composition. On its basis, with addition of necessary additives, the leading producers of equipment get.
It is advisable to buy it in a trusted store.к. Although lawnmowers have lower lubrication requirements than cars, bad oil in the engine can damage it.

Principal differences in combustion systems for the user
Which combustion system is more efficient, 2 or 4-stroke? How to understand the user and buy the best machine? Gasoline trimmers and brushcutters with a 4-stroke motor are not on sale. The two-stroke is much lighter and therefore the grass trimmer weighs little and can be handled by a woman. But there are also two-stroke engines on four-wheelers. Other differences:
- different way to use lubrication;
- Eco-friendliness is higher with a 4-stroke motor, and it’s also less noisy;
- It is easier to repair and maintain a 2-stroke engine;
- The motor life is longer in a 4-stroke, but they are more difficult to maintain because of the oil change in the lawnmower;
- two-stroke engines are lighter and less expensive.
The 2-stroke engine is inferior to the 4-stroke engine in many respects. With a separate petrol and oil supply, it is preferable for light equipment in terms of economy and other indicators. Split-fuel system also cuts fuel consumption by up to 4 times.
The photo shows the engine that was running without oil changes for a long time.
A four-stroke engine has a complicated lubrication system, and it is all the more necessary to use methods to clean the circulating fluid. The oil system has a filter to prevent scale and other debris from clogging the pipes and pump. This part needs to be replaced when dirty.
How to change the oil in a 4-stroke engine
The manufacturer gives a schedule of maintenance of the mechanisms and the order of work in the instruction manual. Lubrication efficiency decreases after 50 hours of operation of the mechanism. That is why an oil change is required. In a household use it is not enough to use the machine for a season and it is necessary to clean the filter, change the oil during the preservation period. Before changing the oil in the lawnmower it is necessary to increase the fluidity of the fluid, start the engine and allow the system to warm up.
You need to unscrew the plug for pouring oil into the tank and use a device to take the fluid under vacuum.
To do this, make a nozzle and siphon off the waste into a prepared container. Only a small part, up to 100 ml will remain in the crankcase and drain from the filter. You need to get rid of this residue by draining the fluid for about 5 minutes through the hole. At the same time change or wash filter in the system. After that pour in new grease and control the level with a dipstick. Usually motor oil is packaged in opaque black plastic so it does not decompose in the light. The required volume is 500-600 ml.
Changing the Oil
Lubricant change should be done in good time, following the maintenance plan in the owner’s manual of the lawnmower. On average, lubrication efficiency decreases after every 50 hours of operation. For the period when the lawnmower will not be working, the oil filter should be cleaned and the oil changed.
- turn on the mower and let the engine idle for 15 minutes;
- in the tank opening, the plug is unscrewed;
- put a container under the mower to catch the used oil;
- tilt the device towards the draining side;
- after draining the waste material the plug is screwed in;
- the mower is placed on a level surface and the opening is opened from above;
- pour in oil to the required level, level is checked with a dipstick;
- close the hole and screw in the plug.
the quantity of liquid poured in is up to 500-600 ml in most machines.
Why do you need engine oil in your lawnmower?
Lubricant is needed for the same reason as it is used in cars and motorcycles: it reduces friction on motor parts and makes them run smoother, i.e. it prevents fast wear and tear. there are other functions besides this one
- remove heat from the engine that is heating;
- protect metal from corrosion and oxidation;
- dissolve soot and deposits, keep them suspended and prevent them from settling.
A good-quality lubricant contains additives to improve its characteristics and protect the engine. Choosing a good oil is a prerequisite if you want your lawnmower to run for a long time.

To get a fuel mixture motor oil is mixed with gasoline in certain proportions. The amounts are listed in the owner’s manual. For example, mineral lubricants are mixed with gasoline at a ratio of 1 to 35, and synthetic. 1 to 50.
- Pour the exact amount of gasoline into the canister;
- add the correct volume of oil using a dispenser;
- Close the tank with the lid;
- stir the compound by shaking the liquid.
Prepared fuel mixture is simply poured inside the gas tank, using a watering can for convenience.
Please see the table below for the proportions of oil to petrol in the composition of fuel. It allows you to quickly determine the volume of mixtures.
The prepared mixture of gasoline and oil can be stored in polypropylene or metal containers for no more than two weeks. Do not keep the composition in polyethylene bottles. The reason is that petrol reacts with the container material, and the resulting products get into the fuel mix. Because of this more soot will be produced during combustion.
It is allowed to fill the fuel mix only when the engine is almost completely cooled down. Do not fill the tank up to the top: leave enough room for the fuel’s thermal expansion.
Observe fire and personal safety rules, while working on preparation and pouring of working composition away from sources of fire.

Changing the oil in a lawn mower with a four-stroke engine
If the engine is not new, lawn mower oil can be changed about once every 25-50 hours of operation. Many people consider car oil known can be oiled again in the crankcase This is an average of 2 to 3 months of operation. Can you pour car oil into a motorcycle oil in a chainsaw or lawnmower. What oil to put in your lawnmower?? Is it possible to fill a single axle tractor with automotive engine oil? You can also determine the condition of the oil without measuring the number of hours worked. Just make sure it doesn’t start to turn black. When this happens, be sure to change the fluid, otherwise the engine may soon simply seize up.
Lawnmower blade resharpening
Operating a lawn mower with blunted knives severely injures the lawn, causing it to become rotten and continue to “hurt” for weeks to come. In addition, mowing grass with insufficiently sharp knives puts more strain on the mower’s engine and drive system parts.
Depending on the configuration of the lawnmower, its blade may be in the form of a simple blade plate or composite blade. In the latter case the upper part of the element serves for mulching the grass. The mower blade can be attached with one or two bolts. To remove the blade, unscrew the fasteners counterclockwise. After removing the blade you can inspect and resharpen it.
The need to sharpen the lawnmower blade is indicated by the presence of “sawing” and chipping on the cutting blade, which deteriorates the quality of cutting the grass. Blades with rounded tip are difficult to repair, because they cause more damage to the grass and get dirty quicker.
It is best to sharpen mower cutting blades using an emery board with 400 to 600 grit. Soak the blade in soapy water before sharpening it. After that, in the course of sharpening, the bar needs to be moistened in the same solution every 10 minutes. To sharpen the knife properly and evenly, the block should be pulled from the center of the area towards its edge.
After sharpening the blade must be corrected. The user will need moisture-resistant sandpaper with grit sizes up to 800 grit. The purpose of straightening is to remove burrs and other defects on the knife surface. To do this, you need to press the sandpaper to the outer plane of the existing descent and make a few smooth movements from the grain. In doing so, the paper should gradually move from the center of the area to the edges.
Repair and maintenance of petrol lawnmowers
Care for lawnmowers with gasoline engines includes a certain number of measures aimed at protecting the nodes of the unit from premature wear and tear.
Mandatory procedures include:
- Use the highest quality gasoline and motor oil. Users must remember that the lawnmower motor needs constant lubrication. Without it, even the toughest engine will quickly overheat and fail;
- Replacement of filters and hoses. the device gasoline mowers include filters and fuel hoses, which gradually become clogged and fail. The best way to clean them is to use gasoline and compressed air from a container. In case of heavy wear and tear, filters and hoses must be replaced;
- timely inspection and replacement of parts of the cutting system. regardless of whether the mower is designed as a rotary or drum mower, its parts must work as smoothly and stably as possible. The user is required to constantly monitor the condition of the cutting system components, sharpen and level the blade edges or change the blade if necessary;
- maintenance of the drive system. most often the unit has a belt drive, which stretches and tears as a result of prolonged use. In this case, the repair of the lawnmower with their own hands is reduced to the replacement of the belt and tensioning rollers;
- Elimination of vibrations and creaks. over time, many lawnmower users are faced with vibration, which appears after 1-2 years after starting to use the machine. The reason for this is the loosening of the bolts. To solve this problem with your own hands is simple enough. for this purpose it is enough to tighten the bolts.
During the operation of the lawnmower it is important to regularly inspect the housing of the machine. If it is made of metal, then sooner or later there will be s of corrosion on its surface. In that case, the operator should immediately remove the rust and cover the problem area with paint.
Making a device for quick change of operating fluids
Cut the silicone hose into equal parts of 1-1.5 meters.Cut off the neck of a bottle. In the cover with a step drill make a hole for the hose. Put it through the hole, everything should sit very tightly, so calculate the diameter of the hole in advance. It will be easier to pull through the silicone hose, if its end is cut aslant.
We put the ends of the tubes through the holes, so that the end of the silicone hose with a capron tube on the other end was lower by 1-2 cm.
To work with this device it is necessary to do the following: We turn on the vacuum cleaner and bring the neck of the plastic bottle with a tube to its inlet pipe. Naturally it sucks in and won’t go anywhere.Close the jar with the lid. And use the other hose to siphon off the desired working fluid.
Under the action of the vacuum it easily gets into the intake can. And thanks to the hard piece of tube on the end, it is very convenient to lower it into the narrow openings. For example, we take a lawn mower in which it is necessary to change the oil. Unscrew the plug with the dipstick, push the solid tube all the way in until it stops. And siphon the used oil into the jar.
The main thing is to watch the level and not to let the oil go to the upper tube, otherwise it will go into the vacuum cleaner.
If you use a larger container to collect, using tubes with a larger diameter, this attachment can also be used to pump oil out of the crankcase or gearbox of the car.
