The purchase of a walk-behind tractor is a rather serious step that you should prepare for in advance. For the long-term operation of the unit, it is necessary to carry out timely preventive work, if necessary, replace parts and, of course, change the oil.

Appointment

When buying a new walk-behind tractor, the kit must contain accompanying documents, in which there are special sections with recommendations for proper care and operation. The names of oils ideally suited to the unit are also indicated there.

First of all, you should understand the basic functions of oil fluids. Liquids do the following:

• system cooling;
• getting the smearing effect;
• cleaning the inside of the engine;
• seal.

During the operation of the walk-behind tractor in an air-cooled engine, the oil liquid begins to burn, respectively, the burnt particles remain on the cylinder. That is why the formation of a smoky exhaust occurs. In addition, resinous deposits are the strongest contaminant for the rest of the walk-behind tractor, due to which the lubrication of the parts becomes more difficult.

It is preferable to fill in oil for a walk-behind tractor together with antioxidant fluids, which are a cleaning agent for the inside of the unit.

For the correct choice of oil, it should be remembered that each individual composition is designed for a specific season and climatic temperature.

In simple words, you cannot use summer oil at temperatures below 5 degrees - this can lead to engine start failure.

• Summer a kind of oily liquid is used exclusively in the warm season. Has a high level of viscosity. There is no letter designation.
• Winter varieties of oils are used during cold weather. They have a low level of viscosity. The letter designation is W, which means "winter" in translation from English. This variety includes oils with the SAE index 0W, 5W, 10W, 15W, 20W, 25W.
• A variety of multigrade oils in the modern world is more popular. Their versatility allows you to fill the engine with fluid at any time of the year. It is these lubricants that have a special index in the general classification: 5W-30, 10W-40.

In addition to seasonality, oils are divided according to their composition. They are:

• mineral;
• synthetic;
• semi-synthetic.

In addition, all oils differ in the performance requirements of a 2-stroke and 4-stroke engine.

In walk-behind tractors, a 4-stroke air-cooled system is usually used, respectively, and the oil must be 4-stroke. In winter, the most preferred option is a gear motor oil such as 0W40.

The price of the issue, of course, is high, but the reaction of the unit lies in its long service life.

Which one is better to choose?

As mentioned earlier, there are several types of oils for motoblocks. It is necessary to use the liquid recommended by the manufacturer of the unit - for this, it is enough to carefully study the labeling of the device and read the instructions.

In addition, each separate type of oil is divided into several types according to its chemical composition. In most cases, manufacturers try to manufacture units with the ability to use the most common types of oils - synthetic, mineral, as well as semi-synthetics such as Mannol Molibden Benzin 10W40 or SAE 10W-30.

It should be noted that this lubricant contains a friction modifier, which creates a strong film on the inner surface of the parts. This significantly reduces the wear rate of the walk-behind tractor.

Another marking that should not be forgotten is the designation of the properties of oil exploitation. It also comes in several varieties. For example, category C is used for 4-stroke diesel engines, and category S is used for gasoline engines.

A certain total can be derived from this data. Considering the type of engine, a high level of demand is directed to multigrade oils marked 5W30 and 5W40 … Of anti-corrosion oils, 10W30, 10W40 are popular.

At temperatures above 45 degrees, oils marked 15W40, 20W40 should be used. For winter colds, it is necessary to use oil liquid 0W30, 0W40.

How to change?

Anyone can change the lubricant in the walk-behind tractor, but if there are any doubts, it is better to contact a highly qualified specialist. The procedure for updating with oil liquid in any models of walk-behind tractors does not differ from each other, whether it is an Enifield Titan MK1000 instance or any other motor from the Nikkey line.

First of all, it should be remembered that the oil changes exclusively on a hot engine, that is, the system must first work for at least 30 minutes. This rule applies not only to four-stroke, but also to two-stroke engines.

Thanks to the above nuance, the warm spent mixture easily flows into the container placed from below. After the used oil is completely gone, you can start the replacement process.

First you need to unscrew the breather plug, drain the remaining used oil and, if necessary, change the additional oil and air filter. Then you need to fill in fresh liquid and return the plug to its place. Pour new oil carefully so that it does not get on other parts of the system, otherwise an unpleasant odor will arise.

In the engine

The primary oil change in the internal combustion engine occurs after 28-32 hours of operation. The next replacement can be done no more than 2 times a year - in summer and winter, even if the unit has been idle for some time. To start the replacement process itself, it is necessary to prepare special attributes - a funnel and a container for draining the spent liquid.

At the bottom of the engine there is a hole with a cap through which old oil can be drained. In the same place, a container for draining is substituted, the locking cap is unscrewed, and the spent liquid is drained. It is necessary to wait a while for the residues to completely drain out of the engine system .… Then the plug is screwed into place and fresh oil can be poured.

Its quantity must be identical to the merged one. If it is not possible to make a measurement, it is better to look at the technical data sheet of the unit, where the required number is indicated in grams. After new oil has been added to the engine, the level must be checked. To do this, it is enough to use a special probe.

It is worth noting that in some engines that are sensitive to oil fluids, for example, Subaru or Honda, the use of oils of a certain class is assumed, that is, SE and higher, but not lower than the SG class.

This instruction is a general guideline for both two-stroke and four-stroke models. More specific information on how to change the oil fluid in the walk-behind tractor is best considered in the instructions for a particular unit.

In the gearbox

The gearbox is the most important part, because it is he who is responsible for converting and transmitting torque from the gearbox. Careful care and high-quality oil used for the device significantly prolongs its life.

To replace the oil composition in the gearbox, it is necessary to perform a number of manipulations

• The tiller must be placed on a hill - best of all on a pit.
• Then the hole for the disposal of used oil is unscrewed. The stopper plug is usually located on the transmission itself.
• After that, a prepared container is substituted for draining the spoiled lubricant.
• After completely draining, the hole must be tightly closed.
• When these manipulations are carried out, clean oil must be poured into the gearbox.
• Then you need to tighten the hole plug.

It is worth noting that in some models of gearboxes, for example, in the Efco line, there are through bolts that determine the amount of oil, which can be guided by when filling fluid. In other models, there is a special dipstick by which you can see the total volume of the filled oil composition.

The initial oil change is carried out after the break-in time has passed .… For example, for the Energoprom MB-800 model, the running-in time is 10-15 hours, for the Plowman ТСР-820 unit - 8 hours. But the line of "Oka" motoblocks was developed taking into account the running in of 30 hours. Subsequently, it is enough to drain and fill in new oil every 100-200 hours of full operation.

How to check the level?

Checking the oil level is carried out using standard technology, to which every person is accustomed. To do this, a special probe is present in the walk-behind tractor device, which goes deep inside the unit. After removing it from the hole, at the tip of the dipstick, you can see a limit strip, the level of which is equal to the level of the oil. If there is not enough liquid, then it must be topped up .… On the other hand, this nuance forces you to check the entire system, since a low level of lubricant indicates that it is leaking somewhere.

In addition to the standard dipstick, some models of walk-behind tractors have special sensors that automatically show the amount of lubricant present. Even in the process of replacing the oil liquid, it can be used to determine how much the size of the lubricant composition or its lack has increased.

Can automotive oil be used?

It is strictly forbidden to use machine oil in walk-behind tractors. Unlike a car engine, a walk-behind tractor has certain principles of lubrication and an appropriate temperature regime for operation. In addition, the motors of motoblocks have certain features. These include the material of construction from which it is made, as well as the degree of forcing. In many cases, these nuances are incompatible with the characteristics of automotive oils.
