Changing the oil in the engine of the walk-behind tractor

The working life of the engine of an agricultural unit depends not only on the quality of its components and assembly, but also on how correctly and how often you will change the engine oil. Adhering to the manufacturer’s recommendations, you can extend the life of the unit and save it from typical breakdowns.

To change the lubricant in the walk-behind tractor, it is necessary to preheat the motor of the unit. To change the oil in the engine of the walk-behind tractor, you need to proceed in the following order:

  • First place the unit in a horizontal position. Holes for filling and draining oil are always located on the left side of the walk-behind tractor engine. The oil remaining inside the motor must be drained through the drain hole, which is closed with a conical threaded plug. If the plug is twisted too tightly, then you can unscrew it with a long screwdriver;
  • Place a wide container with a volume of at least 2 liters under the drain hole and slowly unscrew the plug. Having finally removed it, wait 10 minutes until the lubricant is completely drained from the walk-behind tractor engine;
  • After that, tighten the drain plug and start filling with new engine oil. It is best if you choose 10W40 synthetic or mineral oil as a new formulation. Its volume should be equal to the amount of previously drained oil.

The lubricant in the engine of the walk-behind tractor should be changed at least once every 25-30 hours of operation. If you do not use the unit too often, and all the work takes you about the same amount of time, then you can change the oil once a year. At the same time, remember that if you do not have time to work 30 hours per season, then the oil still needs to be changed, since during the idle time of the walk-behind tractor, the properties of the composition noticeably deteriorate.

If you have just purchased a walk-behind tractor, then you need to change the lubricant in its motor after the first 5 hours of operation of the unit. The fact is that after assembling new motoblocks, small debris remaining inside the engine gets into the oil, which leads to engine jamming and minor breakdowns. In order for the motor of the new unit to be completely cleaned, the oil in it will need to be replaced three more times. 2 times after 5 hours of operation, and the third. after 10 hours.

Is it possible to pour automotive engine oil into the walk-behind tractor?

This question is very relevant, especially among novice farmers. Many of them use automotive engine oil, considering that there is absolutely no difference between it and the composition for filling the motor-block motor.

In fact, using car oil is a big mistake. The fact is that such a tool does not have the characteristics that are needed for the proper operation of the walk-behind tractor. The result of this is accelerated wear of the cylinders and the piston group of the motor, which leads to a breakdown of the walk-behind tractor and the need to completely replace its engine.

To prevent this, you should use a specialized motor oil for a walk-behind tractor, the composition of which fully meets the requirements of an agricultural machine. To fill the motor, you can use 2-stroke or 4-stroke oil. it all depends on the type of engine of the walk-behind tractor.

The manufacturer of the lubricant is also of great importance. formulations from popular brands: Shell, Mobile, Castrol and Liqui Moly have proven themselves best in practice. they work equally well in engines manufactured by BriggsStratton, Subaru and other well-known companies. The third important factor is the seasonality of the engine oil. it depends on this characteristic at what temperatures the composition begins to lose its most important properties. In order not to miscalculate, we advise you to choose an oil for an all-season walk-behind tractor. it does not lose its characteristics at temperatures ranging from 25 to 40 ° C.

Oil in the gearbox of the walk-behind tractor. how to check and change?

The gearbox is an important element of the walk-behind tractor, the function of which is to transfer torque from the motor to the wheels of the unit by means of a V-belt transmission. Gearbox parts are susceptible to increased wear and therefore require regular lubrication. Let’s make a reservation right away that not all the means available on the market are suitable for this purpose.

The best option for lubricating the gearbox is gear oil. This type of compound is excellent for lubricating moving parts. The second important question is how much lubricant to add to the gearbox. To find out, you need to perform a number of specific actions:

  • Carefully place the walk-behind tractor so that its wings are parallel to the surface;
  • Take a wire, at least 70 cm long, and bend one of its sides into an arc;
  • Push the wire through the filler hole until it stops, then pull it back.

Next, look at the wire. If its wet side is 30 cm, then there is no need to add oil to the gearbox. If the lubricant level is lower, then you will need to add as much oil as needed to reach the 30 cm mark on the wire. Fill the lubricating fluid into the gearbox in the following order:

  • Install the walk-behind tractor on the stands;
  • Find the drain plug under the walk-behind tractor at the bottom of the gearbox. Place a wide container under it and start slowly unscrewing the lid;
  • Wait 10 minutes, during which all oil will drain from the gearbox;
  • Tighten the drain cap to the end, unscrew the filler plug and put a funnel in it;
  • Fill the gearbox with about 2 liters of gear oil;
  • Check the compound level with a wire. if the oil contains less than 30 cm of wire, then add some more material.

In most cases, it is required to change the lubricant in the gearbox of the walk-behind tractor at least once every 100 hours of operation of the unit. At the same time, the replacement frequency may differ depending on the recommendations of the motoblock manufacturer. If you use your agricultural machine more than 4 hours a day, it means that you need to change the composition 1 time in 50 hours of operation of the walk-behind tractor.

Oil for walk-behind tractor: for engine, gearbox, transmission

Many new owners of motoblocks are interested in issues related to the use of oils for agricultural machines. Let’s look at what formulations are suitable for lubricating certain mechanisms of the walk-behind tractor, and how to use them for stable operation and extending the life of the unit.

Oil for a diesel walk-behind tractor. features of choice

When choosing engine oil for a diesel walk-behind tractor, you should follow the instructions in the operating instructions. However, if the instructions for use have been lost, then you will have to study the formulations available on the market more carefully.

Diesel engine oils are classified into the following categories. To determine the type and conformity of the composition for a specific walk-behind tractor, special markings indicated on the container with grease will help:

  • API CJ-4. formulations with this marking are designed specifically for motoblocks with a capacity of 10 liters or more. from. and more. The composition of these lubricants has a high viscosity, which guarantees the correct operation of all elements of the motor unit;
  • API CI-4. these oils should be used for engines equipped with different types of injection and pressurization. Such oils have good dispersing properties and high thermal oxidation stability;
  • API CH-4. lubricants with this marking fully comply with all modern requirements and quality standards. Among the advantages of these compositions, one should highlight the ability to fill them in diesel engines that run on fuel, the percentage of sulfur in which exceeds 0.5%;
  • API CA. formulations of this type are best suited in cases where diesel fuel contains a small amount of sulfur. Oils with such markings protect the walk-behind tractor engine from the formation of harmful deposits on its walls;
  • API CB. the use of oils of this oil reduces the risk of corrosion of motoblock bearings;
  • API CC. such oils will be the best option for a turbocharged engine that does not have a supercharger. These compounds help motoblocks withstand prolonged loads and work properly in difficult conditions;
  • API CF-2. oils of this group show themselves well when used in motoblocks that are subject to heavy loads.

After buying a suitable engine oil, you can proceed to pouring it into the motor of the walk-behind tractor. The procedure is quite simple:

  • Place the unit in a horizontal position first;
  • Place a wide container under the drain hole in the engine and remove the plug by gently prying it off with a screwdriver;
  • Wait until the old oil is drained from the motor, and screw the plug back into the hole;
  • Fill the engine with at least 2 liters of new lubricant.

Remember that the oil in new walk-behind tractors should be changed three times with an interval of 5 hours of moderate use. After that, replacement is required no more than 1 time in 25 hours of operation of the walk-behind tractor.

Do I need to add oil to gasoline for a walk-behind tractor?

To find out whether it is necessary to dilute the gasoline for the walk-behind tractor, you need to study the instructions for its operation. It indicates what type of engine the unit is equipped with. 2- or 4-stroke.

If the walk-behind tractor is equipped with a 2-stroke engine, then the fuel mixture for it must necessarily consist of gasoline and oil. During the preparation of the mixture, observe the exact proportion indicated by the manufacturer in the instruction manual. At the same time, fuel for a walk-behind tractor with a 4-stroke engine does not need to be mixed with oil, since all 4 strokes of such motors run on pure fuel.

It should be remembered that motoblocks, into which diesel is poured, also do not need to prepare a fuel mixture. The fact is that all diesel engines are 4-stroke engines and run on clean fuel.

Transmission oil for walk-behind tractor

When choosing a gear oil, the first thing you should pay attention to is the recommendations of the motoblock manufacturer. Each of the brands involved in the manufacture of agricultural machinery uses mechanisms that are different in their design. Accordingly, the latter require oils of different composition. In order to avoid mistakes when choosing a gear oil, we advise you to study the table, which contains the recommendations of the most famous manufacturers of motoblocks.

Walk-behind tractor manufacturer Transmission oil
Neva MB-1 Oils of the brand TAP-158, TAD-17I and other compositions corresponding to GOST 23652-79
Neva MB-2 Oils TM-5, TEP-15, as well as compositions corresponding to the classifications SAE90 GI-2 and SAE90 GI-5
Bison The optimum will be the use of transmission oil TAP 15
Centaur Transmission oils TAD-17I, TEP-15, Tap-15V, TSl-14
Honda The 80W90 oil has proven itself best.
Cascade Gear oils complying with GOST 23552-79 or MS-20 aviation oils

In addition to the correctly selected transmission oil, the frequency of its replacement also plays an important role in extending the life of the walk-behind tractor. Here, as in the case of the choice of the composition, you should pay attention to the advice of the motoblock manufacturer. In the table below you can study the oil change intervals for the most popular brands of motoblocks.

Walk-behind tractor brand Manufacturer’s recommendations
Neva MB-1 and MB-2 It is required to change the gear oil at least once every 100 hours of operation with the walk-behind tractor
Bison The first oil change is carried out after 50 hours of operation of the walk-behind tractor in a moderate mode. All subsequent replacements are made every 200 hours of operation of the unit.
Centaur Transmission oil must be changed after every 75 hours of operation of the walk-behind tractor.
Honda The oil should be changed after every 100 hours of operation with the walk-behind tractor.
Cascade It is best to change the transmission oil every 150 hours of walk-behind tractor operation.

The difference in the frequency of replacing the transmission oil for motoblocks of various brands is due not only to the design features of the units, but also to their condition. After all, if the walk-behind tractor has a slight breakdown, then the transmission oil in it will lose its characteristics much faster than in the case of a completely serviceable unit. Be sure to take this into account, and eliminate all existing breakdowns immediately after their detection.

Walk-behind tractor gearbox: device, types, oil and oil seals change

The gearbox is one of the most important units of the walk-behind tractor. Its task is the uninterrupted transmission of torque from the motor to the wheels by means of a V-belt transmission. Among other functions of the gearbox, one should highlight the change in the speed and direction of movement of the agricultural unit.

Changing the oil in the walk-behind tractor. a detailed algorithm for beginners

Before pouring a new lubricant into the gearbox, it is necessary to clean the mechanism from the used composition. The oil change is as follows:

  • Install the walk-behind tractor on a flat, raised surface. It is best if there is an inspection hole in the garage. by installing the unit above it, it will be much easier for you to change the oil in the gearbox of the walk-behind tractor;
  • The mechanism has 2 plugs. One of them is used to drain the spent composition, and the second closes the hole in which you need to fill in a new product;
  • First, unscrew the oil filler cap. After that, place a wide container under the drain plug;
  • Carefully unscrew the drain cap and wait for the used oil to drain out;
  • After that, screw the drain cap all the way using the spanner wrench;
  • Insert a funnel into the filling hole and add new oil;
  • Then screw the cap back on and unscrew it again. there is a 10 cm dipstick at the end of the cap that will help you determine the amount of oil poured. If the oil is at the end of the dipstick, it means that you no longer need to top up the lubricant. details about changing the oil in the gearbox of the walk-behind tractor will be told in the video.

Under normal operating conditions, the oil in the gearbox of the walk-behind tractor should be changed no more than 1 time in 100 hours of operation. If the unit is used around the clock, then this should be done more often. at least once every 50 hours of operation. This will help prevent damage not only to the gearbox, but also to other mechanisms of the agricultural machine.

How much oil to fill in the gearbox of the walk-behind tractor?

Finding the answer to this question is quite simple. To do this, you will need to proceed in the following order:

  • Place the walk-behind tractor on a flat surface so that the wings of the unit are parallel to the surface itself;
  • Take a piece of wire, at least 70 cm long. it will act as an oil dipstick;
  • Bend the wire into an arc;
  • Push the wire inside the tank to the very end, and pull it out.

If the oil is at the level of 30 cm of the wire length, then there is no need to add oil. If the wire remains completely dry, then you will need to pour at least 2 liters of lubricant inside the gearbox.

DIY gearbox for walk-behind tractor

Many owners of walk-behind tractors often wonder how to make a gearbox with their own hands. This is not as difficult as it might seem. To work, you need to prepare a number of tools. You will need:

  • Straight and oblique screwdriver;
  • Hacksaw for cutting metal;
  • Pliers or pliers;
  • Vise.

The procedure for manufacturing a gearbox for a walk-behind tractor is as follows:

  • First of all, you need to make the body of the mechanism. To do this, take several steel plates and weld them together in the form of a box. To save time, you can also take the body from the Ural motorcycle shaft and modify it a little;
  • Gears are also needed to make the gearbox. They can be taken from the old Druzhba chainsaw. The main thing is that each gear has whole teeth, otherwise the homemade mechanism will not work;
  • Cut off the tip in one of the shafts and drill a hole;
  • On the other side of the gearbox, install the second shaft, and attach the cage and bearings to it;
  • At the end, the output shaft will need to be connected to a pulley.

A home-made gearbox for a walk-behind tractor has a simple design, so that the mechanism can be repaired in 20-30 minutes.

Motor block reducer device

Like any other mechanism of a walk-behind tractor, the reducer of an agricultural unit consists of certain elements. Taking into account the type of the gearbox, its design can be equipped with certain parts. Basically, the gearbox device in detail looks like this:

  • Cover and pulley;
  • Bearings;
  • Input shaft bushings;
  • Adjustment and shift lever;
  • Fork and shift axle;
  • Gear wheel in the intermediate shaft;
  • Shaft block;
  • Double-row chain;
  • Sprocket block;
  • Washers and seals;
  • Input shaft;
  • Right and left axle shafts;
  • Double asterisk;
  • Clutch;
  • Bracket and spring;
  • Clutch fork.

How the gearbox of the walk-behind tractor works will be described in more detail by the mechanism diagram below. Despite the rather complex design of the mechanism, its dismantling and reassembly will not raise questions even for a beginner. This requires:

  • Completely remove the gearbox from the walk-behind tractor;
  • Unscrew the screws and remove the protective covers;
  • Carefully remove the bushing on the input shaft, dismantle the lever and the fork, the switching mechanism;
  • Remove the input shaft and gear from it;
  • Remove the shaft bushings and the chain;
  • Dismantle the shaft block and remove the sprockets from it;
  • Remove the intermediate shaft together with the gears;
  • Remove the clutch, left and right axle shafts.

After completing all the above steps, you get the walk-behind tractor gearbox in disassembly. After repair, the mechanism must be assembled in the reverse order.

What are the gearboxes of motoblocks. types and purpose

Modern walk-behind tractors are equipped with gearboxes that are different in design and purpose. The mechanisms used for the operation of agricultural machines are divided into the following types:

  • Angle gear for a walk-behind tractor. a mechanism of this type serves as a connector for the motor and transmission of the unit. Excellent characteristics and low cost of such a unit make it one of the most popular among farmers. The design of the angular gearbox allows you to modify it, increasing, thereby, significantly increasing the performance of the mechanism;
  • Reducing gear for a walk-behind tractor. the task of this type of mechanism is to increase the power of the motor and reduce the number of its revolutions. Such gearboxes are considered one of the most reliable and efficient mechanisms, since they consist of durable steel parts that are practically indestructible, and a regular air cooling system. Motoblocks equipped with such gearboxes can easily cope with any load, and can solve many economic problems;
  • Reverse gear. this reverse rotation mechanism is installed between the bevel gears, which, in turn, are located on the main shaft of the walk-behind tractor. This reversible circuit is quite simple, so it takes no more than 10 minutes to disassemble it. The main advantage of a reversible gearbox is the ability to reverse. Among the shortcomings, one should highlight the low performance of the mechanism and low speed when moving the walk-behind tractor in reverse;
  • Gear reducer for walk-behind tractor. heavy walk-behind tractors are equipped with a mechanism of this type. It is primarily used to transfer the torque generated by the motor to the wheels of an agricultural machine. Among the main advantages of the gear reducer are high reliability and simplicity of design. The only drawback of this mechanism is the complexity of maintenance. Nevertheless, most motoblock manufacturers equip their equipment with a gear reducer. If you plan to make a homemade gearbox, then it is best to make a gear-type mechanism;
  • Worm gearbox for walk-behind tractor. the distinctive features of this mechanism include the presence of a special screw and a gear worm wheel. For the manufacture of each of the elements of such a gearbox, materials with increased strength are used. Gear ratios of worm gearboxes range from 1 to 4. The number of gears directly depends on the number of threaded channels on the screw of the mechanism. Among the main advantages of a worm gearbox, the high efficiency of the mechanism should be highlighted. It is used in the manufacture of equipment that requires a reduced angular velocity and the highest possible torque. The worm gearbox provides smooth running and low noise level during the operation of the walk-behind tractor.

Each of the listed types of mechanisms has its own advantages and disadvantages. This should be remembered when choosing a walk-behind tractor equipped with one or another gearbox.

What kind of oil to fill in the gearbox of the walk-behind tractor?

The answer to this question should be known not only to beginners, but also to experienced farmers. The serviceability and service life of the walk-behind tractor gearbox largely depends on the quality and characteristics of the oil.

Before purchasing a lubricant, check the agricultural machine manufacturer’s recommendations. The second important factor is the cost of the oil. You do not need to buy the cheapest lubricants, since in most cases they are not capable of ensuring the normal operation of the mechanism.

Oils for the walk-behind tractor gearbox are divided into several types. Depending on the labeling, the following lubricants are found on the market:

  • SAE. These formulations are used in environments with frequent and severe temperature fluctuations. Thanks to this, oils with this marking can be used almost all year round. When buying such oil, you need to pay attention to the number that is in front of the letter W. The smaller the number, the lower the temperature at which you can fill in the oil;
  • ASEA. oils with this marking are considered almost universal. over, the higher the number in the marking, the more difficult the conditions in which the composition is applied;
  • API. oils with this mark are the most common. They are successfully used for lubrication of all types of gearboxes, and provide long-term operation of mechanisms in the most severe conditions.

All of the listed types of oils for the walk-behind tractor gearbox have their own characteristics. Be sure to study them, and compare the indicators with the recommendations specified in the manual for the walk-behind tractor.

Walk-behind tractor reducer

The gearbox is one of the most necessary nodal systems in the walk-behind tractor. With its help, the torque is transferred from the motor to the wheels through a V-belt transmission. Also, the gearbox controls the speed change and the movement of equipment.

What are the gearboxes of motoblocks. varieties and purpose

The design of walk-behind tractors is quite diverse. Modern units are equipped with the following types of gearboxes:

  • angular gearbox for a walk-behind tractor. It is the connecting piece between the engine and transmission. Such a mechanism is distinguished by good characteristics and availability, therefore it is actively used by farmers of small and large land. The corner model can be modified, making it much more productive;

  • reduction gear for the walk-behind tractor. With the help of this type, the engine load is increased and its speed decreases. These gearboxes are among the most reliable and multi-tasking ones, as they consist of durable steel parts and a high-quality cooling system. This technique is highly efficient regardless of workload;

  • reverse gear. This type of reverse rotation is the presence of reverse. The mechanism is installed between the bevel gears, namely on the main shaft. But the gearbox cannot boast of high performance, it has a low speed;

  • gear reducer. This mechanism is installed on heavy models of walk-behind tractors. With its help, torque is transmitted to the wheels of equipment. The gearbox is highly reliable and has a simple design. But maintaining such a mechanism is extremely difficult;
  • worm. This is a gearbox with a special screw, there is also a gear worm wheel. All used spare parts are high-strength, the equipment is efficient and durable. A gearbox of this type is very relevant due to the presence of an angular speed of a reduced type and a torque of the highest type. Even a homemade gearbox will allow the machinery to operate with little noise and a smooth ride. Before using it is worth paying attention to the gear ratios.

Each type of gearbox has its own distinctive characteristics. You should pay attention to them during the selection and installation of the mechanism.

Algorithm for changing the oil in the walk-behind tractor

  • The walk-behind tractor is installed horizontally;
  • Two plugs are installed. Through one, the already used composition is drained, the second is used to fill in new oil;
  • The lubricant filling cap is unscrewed. A wide container is installed under the drain hole;
  • The drain cover is unscrewed until all the used oil flows out;
  • The drain cover is screwed up to the stop with a spanner wrench;
  • The funnel is inserted into the filling hole and new oil of the appropriate grade and temperature is added;
  • The lid is screwed on. With a special probe, you can check the amount of the poured product.

For details on the specifics of the replacement procedure, see the introductory video.

If the equipment is operated under normal conditions, the oil in the gearbox changes once every hundred hours of operation of the walk-behind tractor. When working around the clock, replacement is done every fifty hours. In this way, various breakdowns of agricultural machinery can be prevented.

How to replace oil seals on a walk-behind tractor?

If there is an oil leak, the oil seal needs to be replaced. The algorithm for replacing this element is performed according to the following scheme:

  • Cutters are removed from the shaft, dirt and oil residues are completely cleaned;
  • The screws are loosened on the cover that protects the gearbox. The tightly fitting lid is tapped with a hammer;
  • The worn-out oil seal is pulled out and the place under it is carefully wiped;
  • At the edges, the new oil seal is sealed with a sealed agent. The part is installed and the cover is screwed on.

Disassembling and replacing the oil seal takes a minimum of time. Therefore, before using the walk-behind tractor, you need to make sure that the sealant used is completely dry.

The above recommendations and algorithms are suitable for the following brands of equipment: Neva MB-1 and MB-2, Cascade, Farmer, Oka. Therefore, you can independently perform simple steps to change oil and oil seals.
