Any technical equipment has a complex design, where absolutely everything is interdependent. If you value your own equipment, dream that it will work as long as possible, then you must not only look after it, but also buy good spare parts, fuel and oils. But if you start using low-quality oil, then in the future you will encounter a number of complications and the technique may need repairs. In this note, we will describe which oils (lubricants) are suitable for a particular unit and methods for replacing oils in a walk-behind tractor.

What type of oil should be poured into the motor cultivator

There are many disputes about what kind of oil should be poured into the engine of a home cultivator (walk-behind tractor). Someone is sure that his views are correct, others deny them, but the only thing that can resolve such discussions is the manual for the unit, created by the manufacturer of the product. Any manufacturer in it prescribes a specific volume of oil to be poured, a method for measuring this volume, including the type of oil that can be used.

What all their positions have in common is that the lubricant should be designed specifically for the engine . Two types of oils can be distinguished - oils for 2-stroke engines and oils for 4-stroke engines. Both the one and the other samples are used for motor cultivators in accordance with which particular motor is mounted in the model. Most of the cultivators are equipped with 4-stroke motors, however, in order to establish the type of motor, you need to familiarize yourself with the manufacturer's markings.

Both types of oils are divided into 2 types according to their structure. This aspect makes it possible to distinguish synthetic and semi-synthetic oils, or, as they are also called, mineral oils. There is a judgment that synthetics are more versatile and can be used regularly, but this is wrong.

The use of oils is distributed according to the seasonality of the operation of the cultivator . So, some modifications can be used in the winter season. Due to the thickening of natural elements that are susceptible to a drop in temperature, semi-synthetic lubricants cannot, along with mineral ones, be used in winter. However, the same oils are safely used in the summer season and thoroughly protect the equipment.

Thus, the lubricant is used not only as a lubricant for the components of the engine, but also serves as a medium that excellently restrains the soot produced during fuel combustion and metal particles that arise during component wear. It is for this reason that the lion's share of oils has a thick, viscous structure. To find out what kind of oil is needed for your particular technique, carefully study the operating manual of the cultivator. The manufacturer specifies what kind of oil you need to fill in the motor or gearbox, so it is recommended that you follow these tips.

For example, for the Neva MB2 motor cultivator, the manufacturer advises to use TEP-15 (-5 C to +35 C) transmission oil GOST 23652-79, TM-5 (-5 C to -25 C) GOST 17479.2-85 according to SAE90 API GI-2 and SAE90 API GI-5, respectively.

Oil change in the motor of the "Neva" walk-behind tractor

First of all, you need to find out if you need to change the lubricant? It is possible that its level is still sufficient for the effective functioning of the cultivator. If you still need to change the oil, place the cultivator on a leveled surface and clean the area around the plug (plug) of the dipstick for pouring lubricant into the motor. This plug is located on the bottom end of the motor.

How to set the oil level after changing? Quite simply: by means of a measuring probe (probe). To establish the oil level, it is necessary to wipe the dipstick dry, and then, without twisting the plugs, insert it into the oil filler neck. The oil imprint on the probe can be used to determine which spirit level it is at. On a note! The amount of lubricant in the motor should not overlap the limit mark in any way. If there is an excess of oil in the container, it will pour out. This will increase the unnecessary costs of lubricants, and hence the operating costs.

Before inspecting the oil level, the engine must cool down. A recently functioning motor or gearbox will provide incorrect parameters for the amount of oil, and the level will be significantly higher than it actually is. When the components have cooled down, you can measure the level accurately.

How much grease does the gearbox need to be filled?

The question of the amount of transmission oil is quite fundamental. Before answering it, you need to set the lubricant level. This is extremely easy to accomplish. Place the cultivator on a level platform with the wings parallel to it . Take a 70-centimeter wire. It will be used instead of the probe. Bend it into an arc, and then insert it all the way into the filler neck. Then remove back. Inspect the wire carefully: if it is 30 cm stained with grease, then the lubricant level is normal. When there is less than 30 cm of lubricant on it, it must be replenished. If the gearbox is completely dry, then 2 liters of lubricant will be needed.

How to replace the lubricant in the gearbox?

The procedure is as follows.

• Before you start filling with new fluid, you need to drain the old one.
• Place the cultivator on a raised platform. This will make it easier to drain the lubricant.
• You will find 2 plugs on the gearbox. One of the plugs is designed for draining, it is located at the bottom of the unit. The other closes the filler neck. The filler plug is turned out first.
• Take any reservoir and place it directly under the oil drain plug.
• Unscrew the oil drain plug carefully. The transmission oil will begin to drain into the container. Wait until absolutely all of the oil has drained, after which you can screw the plug back into place. Tighten it to the limit with the spanner wrench.
• Insert a funnel into the filler neck. Get an appropriate lubricant.
• Fill it up to the required level. Then replace the plug. Now you need to find out the level of lubricant. Tighten the plug with the dipstick all the way. Then unscrew it again and inspect.
• If there is lubricant at the tip of the probe, no more need to be added.

The procedure for changing the transmission lubricant will depend on the modification of the walk-behind tractor . But basically, replacement is done after every 100 hours of unit operation. In some episodes, more frequent replacement may be necessary: after every 50 hours. If the cultivator is new, then the initial replacement of the lubricant after running in the walk-behind tractor must be performed after 25-50 hours.

A systematic change of transmission oil is necessary not only because the manufacturer advises it, but also for a number of other circumstances. During the operation of the cultivator, foreign steel particles are formed in the lubricant . They are formed due to the friction of the components of the cultivator, which are gradually crushed. Ultimately, the oil becomes thicker, which leads to unstable operation of the walk-behind tractor. In some cases, the gearbox may fail. Filled with fresh lubricant prevents such unpleasant events and eliminates repairs. Replacing a lubricant is several times cheaper than purchasing and installing a new gearbox.

If you want your technical equipment to function for a long time and correctly, do not ignore the timely oil change . How to maintain and clean the oil filter of a motor-cultivator Maintenance of the air filters of the motor-block motor must be carried out according to the maintenance intervals indicated by the manufacturer or as needed if the technical equipment is used in conditions of high dustiness. It is advisable to inspect the condition of the air filter every 5–8 hours of the operation of the walk-behind tractor. After 20-30 hours of activity, the air filter needs to be cleaned (if it is damaged, change it).

Do I need to fill and change the oil in the air filter of the cultivator?

In the vast majority of situations, it is enough just to slightly saturate the air filter sponge with machine oil. However, air filters of certain modifications of motoblocks are in an oil bath - in such a situation, lubricant should be added to the level marked on the oil bath.

What lubricant to fill in the air filter of the walk-behind tractor?

For such purposes, it is recommended to use the same lubricant that is located in the motor sump. According to the generally accepted standard, machine oil for 4-stroke engines is used in the engine of the walk-behind tractor, as well as in the air filter.

In accordance with the season and the ambient temperature, it is allowed to fill the engine with seasonal lubricants of the 5W-30, 10W-30, 15W-40 classes or all-weather engine oils with the widest temperature range.

A few simple tips

• Never use additives or oil additives.
• The lubricant level must be checked when the cultivator is in a level position. You need to wait until the oil is completely drained into the pan.
• If you decide to completely change the lubricant, drain it with a warm engine.
• Dispose of the grease in such a way that it does not harm the external environment, in other words, do not pour it onto the ground or throw it in the trash. For this, there are specialized collection points for used motor lubricant.
