How to change the oil in a walk-behind tractor

Oil change in the Neva walk-behind tractor

Every farmer knows that for optimal performance of a technical device, appropriate care is required. And also the service life will be influenced by the parts and consumables that the summer resident will acquire as the equipment is used. Today, almost every farm has a single-axle tractor, it helps the employee to carry out various tasks related to the care of the field and the cultivation of crops.

Contrary to popular belief, Chinese technicians have reached a high level of development not due to not high-quality components, but due to low production costs. So, the single-axle tractor Neva has all the characteristics of its European counterparts. The article will tell you why you need to change the oil in the Neva walk-behind tractor, and also acquaint you with the basic principles of this type of maintenance.

Why change the oil in the gearbox? If, during the maintenance process, the owner of the walk-behind tractor wants to save money and uses low-quality oils, or does not change it at all, the walk-behind tractor may have problems. At the same time, he will experience difficulties at work, and may even become unusable.

And you also need to remember about the frequency of replacement. You should know that by choosing even the most expensive oil, but changing it every few years, you expose your unit to heavy loads, and, therefore, destroy its insides. Regular oil change ensures smooth operation of the gearbox and significantly extends its service life.

The gearbox oil can be changed as follows: Place the single-axle tractor vertically on a flat surface; It is advisable to put a medium-sized container on the bottom, up to 5 liters; Now you need to remove the breather and clean it; We bring the above container under the screw and, having unscrewed it, wait until everything comes out; We return the screw to its place, and fill in new oil; After closing the breather, you can start a test run of the equipment.

In addition, it must be said that a single-axle tractor, like any technique, requires running-in. In this case, after 40 hours, it is necessary to change the oil again. In the future, the procedure should be repeated every 140-180 hours of operation, and in case of downtime. every couple of years. Many novice farmers neglect running-in, and spoil their walk-behind tractors already in the first season. It is not worth saving, it is better to buy 2 bottles of oil than to buy a new gearbox or a single-axle tractor later.

Engine Oil As with the gearbox, the engine constantly requires oil to be added and changed. Its brand can be selected by reading the instructions offered to the walk-behind tractor. The manufacturer will indicate the amount and timing of application. If the device was purchased from hands, then you need to find out the brand of the engine itself. For example, a Chinese single-axle tractor has a Honda engine of one power or another. Then, the oil change in the Neva walk-behind tractor will be performed twice a year. But it should also be topped up as needed, namely: before starting work, check the oil level, and top up if necessary. Break-in is carried out within 20 hours of operation, the oil will also need to be changed.

In a new walk-behind tractor, after five hours of operation, the oil in the engine must be changed without fail. After assembling the unit, small debris remains in its engine and, getting into the oil, it is able to jam the motor of the walk-behind tractor after the first hours of operation, and lead to its breakdown. In order for the engine to be completely cleaned of this debris, the oil should be changed several more times, every 5 and then 10 hours of operation of the device.

After running in and cleaning the engine, the oil in the walk-behind tractor is changed at the time indicated in the instructions, and usually this procedure must be carried out after 25-50 hours of operation of the device. If there is no exact data on changing the oil in the instructions, then it is necessary to take into account the operating conditions of the unit and look at the color of the oil. If it has turned black, you need to change it urgently.!

For a better oil change, the engine in the walk-behind tractor must be warmed up. The container should also be prepared in order to drain the used oil into it. a single-axle tractor with a warmed-up engine tilts a little, and a container is placed to it, after which you should unscrew the drain plug from the engine and wait until all the oil is drained into the container. Further, the plug is twisted and new oil is poured into the engine. If the engine does not have a drain plug, then the oil is drained through the filler hole.

Usually, the oil is changed in the crankcase of the engine every twenty-five or thirty hours of operation, especially if the engine is in a medium-power walk-behind tractor and is working “under tightness”. Regular oil changes extend engine life.

The process of changing the oil described in the instructions may not always seem clear to an ordinary user, but in fact there are no particular difficulties in this procedure, although there are some points that it is better not to forget about.

  • First, the single-axle tractor is set in a horizontal position. The filling, measuring and draining holes are always located on the left side of the engine. The used oil is drained off through a drain plug closed with a threaded conical plug. If it is tightly twisted, then you can unscrew it with a long screwdriver.
  • The container for draining must be at least two liters in capacity, and this can be an ordinary canister. The amount of new oil poured into the crankcase is the same as the amount of the drained oil. To date, the best oil recommended by the manufacturers of such units is considered to be oil with a viscosity of 10W40, synthetic or mineral.

If the required 25-30 hours are worked out per season, then the oil is changed at least once a year, even if the volume of these operating hours is not accumulated, because during this time the oil is oxidized and its properties deteriorate. Timely oil change of the walk-behind tractor, especially during seasonal work, ensures good and long-term operation of the walk-behind tractor, and such a replacement does not entail large expenditures, which can result in a breakdown in the engine, with poorly lubricated rubbing parts. It is also recommended, together with an oil change, to put a new plug in the engine every time.

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 must be poured into the motor or gearbox, therefore it is recommended to follow these tips.

For example, for the Neva MB2 motor cultivator, the manufacturer recommends using TEP-15 transmission oil (-5 C to 35 C) 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.

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

In the vast majority of situations, it is enough just to slightly saturate the air filter sponge with machine oil. However, the 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.

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, 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 inappropriate lubricant costs and therefore 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 to replace the lubricant in the gearbox?

  • Before you start filling with new fluid, you need to drain the old.
  • Place the cultivator on a raised platform. This will make it easier for you 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 the oil has drained, after which you can screw the plug back into place. Tighten it to the limit with the spanner.
  • Insert a funnel into the filler neck. Take the 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, do not add any more.

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).

How much grease is required to be poured into the gearbox?

The question of the amount of transmission oil is quite fundamental. Before answering it, you will 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 change the oil in the “Neva” walk-behind tractor?

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 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 recognized 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 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 most extensive temperature spectrum.

Some simple tips.

  • Never use additives or additives for oil.
  • 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.
