What Grease To Lubricate A Trimmer Reducer

Types of Trimmers

For a long time, they have not used such a tool for mowing grass as an ordinary scythe to trim the lawn. Of course, this instrument remained in the villages, but in order to mow a lawn or lawn covered with grass, grassy roadsides in a country house or cottage, a trimmer is used. This is a type of garden tool that combines a scythe and a lawn mower.

Trimmers are different, but basically they can be shining to three types. These are gasoline, electric and powered by a battery.

The most powerful are lawn mowers with a gasoline engine. They are considered a professional tool, they are used not only for lawns near the house, but also by employees of housing offices and road administrations to bring the lawn-covered areas in order. The engine of this tool with high power, usually there is air cooling. Having a container in the backpack with gasoline and oil for the engine, the worker is not tied to the place and can process large sections at a considerable distance, and with a fairly high speed.

Of course, such a tool also has its drawbacks, for example, a large amount of exhaust gases, a lot of noise, which is heard even when the windows are closed, when they mow grass on the street. If, for example, one of the trimmer elements fails, it will be difficult to make repairs yourself without experience. In addition, he has a large, comparatively weight, it will be difficult for a woman to work with him, and the price is much higher than the rest of the species.

An electric motor tool powered by an electric cable is a less powerful tool. He has an upper engine location and a lower location. Both models have both their pros and cons. Due to the binding to a power source, it is used in personal households, although the device has to be equipped with an extension cord.

Power Cable Trimmer

But they are more convenient in work and have a small weight. In addition, the noise level and vibration level are small, although they cannot mow thick plant stems. Easy to repair and maintain. Reasonable prices.

The third type of trimmers is battery powered. They do an excellent job where it would be impossible for the mower to come up with a cable, convenient to operate, they can be easily moved from place to place, they will not get tangled in the wire and will not cut it. They work quietly, inexpensively.

There are difficulties in their work, it is a battery that constantly needs recharging, the smallest power compared to other types. Therefore, they are bought as an addition to the other two tools, and the choice of models is not so big either.

Trimmers and major differences in models

If you take apart any gas mower, you can make sure that it is made almost the same, with the exception of additional options and design.

The structure of the gas trimmer

If it is an electric tool, it has a slight difference:

Electric trimmer, example configuration. 1. engine running on gasoline; 2. fuel tank; 3. starter handle; 4. rod, can be disassembled, telescopic, solid; 5. the handle, which is controlled during operation, may have a different shape; 6. buttons to control the trimmer; 7. the buttons are connected to the engine via a small cable; 8. gearbox, which needs constant maintenance and the addition of special oil. It transfers rotation from the engine to the shaft on which the spindle is mounted; 9. a cutting tool that is mounted on a spindle, which in turn consists of either a reel with fishing line, which cuts grass, or a special knife; 10. a casing to protect the worker from flying pieces of stems.

As you can see from the photo, its difference is that there are not so many control buttons, there is one. either turn it on or off, the engine can be located either below, near the cutting tool. In this case, it is easier to work with such a tool, but mowing wet grass is not recommended. But in this case, the gearbox, as a part, is absent, since rotation is transmitted directly from the motor directly to the spindle shaft and the cutting unit. Naturally, like all other equipment that do not have a gearbox in design, it has low power.

If the engine is at the top, it is more practical and the engine is more durable.

In addition, such a mower has a much greater power.

If we consider the battery version, it has an engine and a battery in the upper part of the rod.

Lawnmower Care and Maintenance

Maintenance of lawn mowers, both with a gasoline engine and with an electric engine, although it has its own differences, is quite possible on its own. Tracking the sharpness of the blades, sharpening correctly, if they are dull. this is not a particularly difficult task. If there is no equipment for sharpening at home, you can grind them in workshops. In order for them to wear equally on both sides, we periodically turn them over to the other side.

Check the air filter that is mounted on the gas spit at intervals of one week, at least. Wet with oil, if necessary, change if contaminated. We check the candles and the muffler for pollution from soot.

If the engine is electrically powered, alternate the time specified in the passport with the cooling time of the engine. If the equipment has a cutting element for the fishing line, you also need to monitor it, the coil on which it is wound is also periodically cleaned.

Untimely cleaning of the electric motor leads to the fact that moisture accumulates in it, and the loss of its power in the gasoline engine.

It is especially important to pay attention to the maintenance of the gearbox. This part is very important in the operation of the mower, unless the engine is directly connected to the cutting unit.

The first is to ensure that dirt does not accumulate there.

Second, do not forget to apply grease on time, which is intended for the trimmer gearbox. You can ask the seller of the equipment what kind of lubricant is needed for the trimmer gearbox that you are going to buy. They will answer this question as correctly as possible, since the life of the trimmer depends on it, and this is the warranty. Some trimmer manufacturers recommend using their proprietary grease for the trimmer gearbox, for example, such as Husqvarna, Huter, Makita.

Husqvarna trimmer gear lubricant

The fact is that in the process of work the load on the gear increases, since the speed of rotation is constantly changing. At the same time, adhering grass, especially in wet weather or dew, creates its own additional load. When deciding which lubricant is best to use for the gear of your trimmer, you need to decide separately for each model.

If these are Russian or Russian-Chinese manufacturers, a specific brand of lubricant is not indicated here.

Which grease is best to lubricate the trimmer gear

Too many people use Litol for this purpose, its only advantage is its low price, and many do replace the lubricant in the trimmer gearbox with Litol. However, this grease is thicker and more viscous than that of specialized lubricants; it does not have special additives in its composition. Therefore, you need to constantly monitor what level of lubricant in the gearbox, add it every 20 hours. In addition, Litol cannot be used on aluminum parts. Therefore, on what grease will be in the trimmer gearbox, its performance and its service life will depend.

As already mentioned, it is very good if, when buying a mower, you immediately get the grease of the same company as the mower.

Special grease from Oleo-Mac for gearboxes

In addition to the fact that special greases have the density and viscosity necessary for such parts, it must be remembered that children can play on the lawn, adults can rest, and waste from grease that is not suitable for this purpose is superfluous.

How is grease and grease added to the electric trimmer gear

In order to lubricate the gearbox, there are technological holes in it. To do this, unscrew the cap of the tube of grease and squeeze the grease into the hole.

We unscrew the screw and enter the grease into the technological hole

If the grease is in a different container, we draw 5 cubes into a syringe and inject the grease with a syringe.

Lubrication can also be introduced through a tube

If it is a reducer from a gasoline engine, we find a plug, it is usually indicated on the diagram. And a little more than the gearbox from the electric mower. We clean it and the place around it, so that the dirt does not get inside when opened. Then, we put the trimmer on the surface (it must be turned off) sideways and with one hand we squeeze out the grease slowly in the way described above, and with the other we rotate the knife so that the grease is evenly distributed inside. Then close the plug tightly on the gearbox and tube or syringe. You need to lubricate at least after 25 hours of operation, and what kind of grease to lubricate the trimmer gear, you choose. The principle of operation of the gearbox and gasoline and electric is the same.
