The ignition system is electronic, which includes: magneto, spark plugs, high-voltage wire.
It is necessary to start the engine correctly, according to the algorithm specified in the instructions. If certain actions are not followed, there is a high risk of engine failure. We invite you to watch a short video on how to start the Oka walk-behind tractor:
Gearbox device
The walk-behind gearbox transmits torque from the engine to the wheel drive. Its design is as follows:
We suggest studying the cross-sectional diagram of the Oka walk-behind tractor gearbox:
What type of gearbox can be installed on the Oka walk-behind tractor?
It is best to use a collapsible chain gearbox, which consists of a collapsible housing with bolted connections. Unlike a non-separable gearbox, such a mechanism can be easily repaired and will last for many years. A gear reducer can be installed on more powerful equipment; a worm gearbox is rarely practiced in walk-behind tractors.
The design and principle of operation of the carburetor
Carburetors are gas distribution devices inherent in gasoline engines. The function of the carburetor is as follows:
- regulates the amount of incoming gasoline and air;
- saturates the air with gasoline vapors.
We suggest that you familiarize yourself with the carburetor diagram for the Oka:
The lineup
The Oka walk-behind tractors, produced and sold now, for the most part belong to the glorious MB-1 , which has proven itself well. As with other devices of this kind, it is recommended to change the oil after the first 5 hours of use. Then the intervals increase to 25-30 hours. It is allowed to use mineral oil for carburetor automobile engines. In the latest version, which appeared in 2010, cable control was introduced, providing instant emergency stop of the engine.
Almost all produced models belong to the MB-1D . A striking example is the model “MB-1D2M16” . This walk-behind tractor is equipped with a Chinese-made Lifan 177F engine with a total power of 9.0 hp. With. The unit is designed for 2 forward and 2 reverse speeds. The plowing strip can vary from 72 to 113 cm. If several passes are made, it is possible to reach a depth of 30 cm. A V-belt scheme is chosen to transfer the force generated by the motor to the working parts. The chain gearbox can operate at two speeds. To fill the gearbox, use 1.5 to 2 liters of transmission oils.
The delivery set includes:
- pneumatic wheels;
- 4 loosening cutters;
- opener
The engine that drives the walk-behind tractor itself and auxiliary tools runs on motor gasoline and has a four-stroke cycle. With a cylinder volume of 270 cm3, the capacity of the gasoline tank is 6 liters. Transport speeds forward and backward are 9 km/h, minimum - 3.6 km/h. The wheel layout of the walk-behind tractor is 2x2. Thanks to its ground clearance of 14 cm, it confidently drives around any minimally maintained summer cottage area. In order for the block to turn at the command of the steering rod, a radius of at least 33 cm is required. The track size is adjusted in stages. Due to extensions, it can be increased from 31 to 59 cm. The standard number of cutters is 4; if this is not enough, you can add 2 more.
Maintenance of Oka
Maintenance of a walk-behind tractor includes several stages:
- Daily work before and after use.
- Change of oil.
- Scheduled inspection.
- Preservation for long-term storage.
Let's consider the first point.
Before operating the Oka walk-behind tractor, you must:
- check the oil and fuel levels; only fill in high-quality working fluids;
- check the reliability of bolted connections;
- check tire pressure.
After use you must:
- thoroughly clean and wash the walk-behind tractor;
- dry in the shade;
- lubricate all components and mechanisms;
- put into storage.
No less important is the second point - “Oil change”. The first replacement is made after running in the walk-behind tractor. After every 25 operating hours, the oil level in the gearbox is checked and fluid is added if necessary. The transmission oil is changed every 50 operating hours.
Routine inspections must be carried out after the first 100, 200 and 500 engine hours; it is recommended to completely change the oils, both in the engine crankcase, gearbox, and transmission.
How to check the oil in the gearbox of a walk-behind tractor?
Monitor the amount of oil constantly. Otherwise, careless attitude to technology will lead to fatal consequences. Fresh oil is added every 50 hours. Along with this, excessive loads should be avoided, which ultimately lead to the rapid deterioration of mechanisms and components. Let's move on directly to changing the oil:
- We install the equipment on a flat area. We find a probe 70 cm long.
- The dipstick is bent and pushed into the oil fill hole until it stops, after which we remove the rod.
- We observe the oil level, which should be at least 25 cm. Add 2 liters of oil to the dry gearbox, at least 1.5 liters.
The filling oil must be GOST specific. It makes no sense to use cheap oil, because sooner or later it will cause breakdowns inside the walk-behind tractor gearbox.
Advantages of Oka walk-behind tractors
The Oka walk-behind tractor is a serious piece of equipment for real professionals; it is designed to perform a range of work on the ground, in a summer cottage, and can be used as a mini snow blower in combination with special attachments.
The main advantages of Oka walk-behind tractors that made them so popular among farmers and summer residents:
- economical, low noise engines
- reaches a speed of 10 km/h with a trailer;
- small size (disassembled equipment can be transported even in the trunk of a car);
- the ability to cultivate not only well-groomed soils, but also virgin lands;
- multifunctionality (used for watering, cleaning, transportation, etc.).
The walk-behind tractor is equipped with a four-stroke engine, gearbox, steering wheel, clutch and two wheels. Instead of wheels, four cutters can be installed on the walk-behind tractor for cultivating the soil.
Advantages and disadvantages
The Oka walk-behind tractor, model MB-1D1M10, is simple, but at the same time equipped with a power take-off shaft. This shaft can be used to connect auxiliary equipment of the same brand. The MB-1D2M16 model is designed for work on large plots, in vegetable gardens up to 50 acres. Regardless of the specific version, walk-behind tractors from the Kaluga plant can be considered a good choice for cultivating land on a private farm.
The advantages of the devices are:
- minimum noise level;
- engine reliability;
- rational choice of speed modes for specific modifications;
- relatively small size and weight;
- minimum turning radius;
- low care and maintenance requirements.
Problems may be associated with low wear resistance of drive belts. However, the basic package always includes additional sets of them, so troubleshooting is quite possible. Moreover, the design is very simple, and repairs do not even require contacting service organizations. And the lightness and compactness of walk-behind tractors simplify their movement and storage. Taken together, the positive qualities far outweigh their negative side.
Engine
Depending on the modification, the Oka walk-behind tractor is equipped with engines from different manufacturers (DM-1M, DM-1M1, MITSUBISHI GT600 6.0/4.4, I/C 6.0 HP 6.0/4.4, Honda GX-200 6.5/4.8, Lifan 168 F-2A 6.5/4.8, Vanguard 6.5 HP 6.5/4.8, Lianlong 168F-1A 6.5/4.8, Robin Subaru EX 17 6.0/4.4, Robin Subaru EX21 7.0/5.2, KADVI 168F-2A).
One of the popular modifications is the Oka with the Lifan engine . This engine is economical, and its functionality allows it to be installed in small-sized equipment (motor cultivators, walk-behind tractors). Lifan is manufactured in China and has proven itself to be a durable and reliable engine.
The choice of model is made depending on the area of land the operator intends to cultivate using the walk-behind tractor, as well as on the main tasks (plowing, cultivation, digging up potatoes, etc.) that the device will perform.
Engine malfunctions
Let's figure out why the engine on the Oka walk-behind tractor may be acting up? So, the main reasons that the engine does not work and the walk-behind tractor does not start may be the following:
- insufficient fuel or oil level;
- low-quality gasoline;
- clogged fuel or oil filter;
- problem with spark plugs or seals (oil is leaking; spark plugs need to be replaced);
- the angle of inclination when setting up the walk-behind tractor is exceeded (more than 15 degrees, start the walk-behind tractor on a flat surface);
- the integrity of the electrical wiring is compromised;
- rupture or delamination of transmission belts;
- poor tire pressure in combination with any of the above reasons;
- attempt to start the engine without warming up;
- The storage temperature of the walk-behind tractor is too low, as well as a big minus outside when starting the equipment (store the walk-behind tractor in a warm room; in sub-zero temperatures, pour warm oil into the engine and gearbox).
Purpose and technical characteristics
The Oka walk-behind tractor can be used for a variety of needs. The company that produces these products has been operating since 1966. The accumulated experience has allowed us to create a device capable of:
- plow the land;
- transport soil and household and construction waste;
- move fertilizers, pesticides;
- clear the area of snow and various dirt;
- harvest root crops.
The difference between individual modifications of the Oka is associated mainly with the installed motors. Their maximum effective power can be 6, 6.5, 7 and 8 hp. With. Regardless of the specific modifications, chain gearboxes are used. The dimensions of the MB-1 model are 150x60x105 cm. The operating weight of this walk-behind tractor does not exceed 90 kg, and its ground clearance is 14 cm.
Change of oil
According to the manufacturer's instructions, for the gearbox of Oka walk-behind tractors it is recommended to use transmission oil TAD-17I or TAP-15V, and any oils in accordance with GOST 23652-79. Oils can be mixed in different proportions.
For the engine, use automotive motor oil type M-53/10G1 or M-63/12G1. The oil must comply with API: SF, SG, SH and SAE: 10W-30, 15W-30.
- during the break-in period after 20-25 hours;
- then, after the next 25 hours, the oil is checked and added to the gearbox;
- After 50 hours of operation, the transmission oil is changed;
- During scheduled technical inspections, after 100, 200, 500 or more hours, the oil from all reservoirs must be drained and replaced with new one.
Since the manufacturer currently produces modifications of the Oka walk-behind tractor only with gasoline engines, you should choose AI 92 or 95 gasoline for refueling.

The belts are removed manually by loosening the adjusting bolt. Belts are replaced with similar ones that are suitable in width and length. It is advisable to purchase spare parts, incl. and belts, in stores of branded spare parts for walk-behind tractors. Such stores work directly with manufacturers.
Video review of replacing walk-behind tractor belts:
How do you know whether to tighten the belt?
If you press down on the belt with your hand, it should only flex slightly when pressed. If they sag, the engine will hum, and blue smoke may even appear from overheating. Worn belts recessed into the belt cells need to be replaced. First, remove the nuts holding the belt frame together. Next, use the adjusting bolt to tighten the belts, periodically checking the tension manually.
The same manipulations are carried out after installing new belts in order to regulate them.
Device diagram and operating principle
Now it will be useful to see how it all works. One of the most popular modifications of Oka walk-behind tractors comes with a Lifan engine. It is economical and at the same time highly functional. To transmit force and reduce engine speed, an MB-1 gearbox is installed. This device can effectively operate for over 3500 hours. Early versions of the walk-behind tractor were equipped with gearboxes with needle bearings. Newer versions of gearboxes are already of the ball type. Changing one type of gearbox to another is easier and safer than trying to replace the bearings themselves. Only the oil prescribed by the manufacturer should be poured into gear units. But no less important is what attachment the force will be transmitted to through the gearbox.
The basic package usually includes a milling cutter, but its role is limited to pre-cultivation of the land and preparation of the site for planting various plants. They prefer crow's feet cutters, which are capable of grinding even a strong soil layer to a fine dust. Each of the 3 sections of the soil cultivator has 3 sharp steel knives. The plow is also suitable for plowing the land, but not for preparation, but for planting the plants itself. To connect plows to walk-behind tractors, hitch devices are used. They are either included in the package or purchased additionally.
With the help of the so-called hiller (or otherwise plow) you can:
- hill up already developed plants;
- cut furrows for planting;
- improve soil aeration.
Since milling and plowing even “light” soil requires significant effort, it is recommended to use weighting agents. They are specially designed to complement the wheels. Most often, those models whose weight does not exceed 120 kg have to be weighted.
To perform other functions the following are used:
- harrows;
- lugs;
- potato planters;
- tuber diggers;
- cargo carts (trailers);
- adapters;
- mowers
To ensure that all auxiliary equipment can operate normally, drive belts are used - 1 each for forward and reverse. They interact with the corresponding pulleys. The spare parts included in the belt drive form the clutch. Working together with the gearbox, it acts as a transmission. Belts and other components are designed in such a way that the walk-behind tractor remains stable when changing speed, and that the power changes smoothly.
Lighting
The most popular modifications, unfortunately, are not yet equipped with a headlight, but some equipment owners themselves regulate this nuance.
In the basic models produced by Kadvi, there is no light on the walk-behind tractor.
It is very easy to make lighting on a walk-behind tractor; a basic electric generator is usually used for this. The connection is made as follows:
- a device that generates electricity is connected to a button on the steering wheel;
- lay the necessary wires from the button to the electrical equipment (for example, a headlight);
- the wires are insulated in any way from mechanical damage and water (most often a corrugated pipe is used).
If the generator power is sufficient, the headlight will be bright. If there is insufficient power at low engine speeds, the light will go out. Some craftsmen replace the walk-behind tractor generator with a car or tractor generator.
How to make a light for a walk-behind tractor or mini tractor with your own hands:
In any case, even without using a generator, you can make light on a walk-behind tractor. All you need is a 12-volt battery and an LED lamp. The battery can be taken from an electric bike or scooter.
It is recommended to place it between the gearbox and the engine. According to the diagram above with an electric generator, connect the battery. The wires from the battery are routed to a switch and then to a headlight or other electrical equipment.
Be sure to insulate the wires.
Features of MB-1 belts
- Perform the work of the transmission and clutch mechanism.
- Thanks to the thoughtful arrangement of the belts on the walk-behind tractor, the stability of the mechanism when changing speed is guaranteed.
- Provides smooth power changes.
It is important to note that, in comparison with a chain drive, which is unpretentious in maintenance, a belt drive is cheaper and easier to operate, which compensates for its wear and large size. Therefore, most often farms prefer to have equipment with the latter drive.
Gearbox
Owners of Oka walk-behind tractors, like any other equipment, sometimes encounter operational problems. Including the operation of the gearbox.
Next, we will look at the most common difficulties, their probable causes and ways to solve the problem:
- There is oil leaking on the output shaft: the axle shaft cuff may be worn out (replacing the cuff will help);
- the gearbox is jammed (one of the reasons is a broken chain; it needs to be replaced);
- it is not possible to change gears (you need to disassemble the gearbox and replace broken parts);
- the mechanism for disengaging the axle shafts is broken (adjusting the tension of the axle shaft control cable will help).
The figure below shows a cross-sectional diagram of the walk-behind tractor gearbox
If the normal operation of the oil seals is disrupted, namely when oil leaks, the oil seals should be removed and inspected for cracks and wear. Replace if necessary.
Tips for choosing
The decisive factor when choosing a walk-behind tractor, as always, is its power. The fact is that it depends on it whether the device will be able to plow virgin soil, or whether it is only capable of working on already improved land. Of course, the structure of the soil also plays a role. To solve a wide range of problems, experts recommend models with power take-off shafts. Important: if the main job is milling the earth, you need to choose a lighter machine.
Chain gearboxes are recommended for light and medium walk-behind tractors. Worm drive options are used much less frequently, and only on the lightest machines. When it comes to motors, one of the best products is from . These are first-class products that are much more advanced than Russian products, and are no worse adapted to local conditions. Japanese engines are the highest quality, but they are the most expensive.
Carburetor adjustment
The carburetor valves of the walk-behind tractor require periodic adjustment. Violation of the norm of the distance between the valves causes a change in the periodicity of the gas distribution stages, as a result, the engine does not reach the declared power. If the gap is large, noise appears and the valves themselves become deformed.
As soon as any extraneous noise appears in the engine during operation of the walk-behind tractor, the carburetor should be adjusted. To adjust, you need a screwdriver, a wrench and a blade (after all, the valve clearance norm is from 0.1 mm to 0.15 mm).
The MB-1D walk-behind tractor uses a membrane-type carburetor, model DM 1.08.100. The external view of the DI1.08.100 carburetor is shown in the figure below:
1 — full throttle screw; 2 — idle screw; 3 — air damper lever; 4 — minimum speed screw; 5 - flange; 6 - dosing device; 7 - pipe; 8 - tide: 9 - hairpin; 10 - nut; 11 — inlet fitting; 12 - button.
Features of care
Experts recommend, of course, to use only officially supplied original spare parts. To improve the operation of the device, the gear shift roller can be modified. More precisely, a handle is attached to it, which allows you to work more conveniently. A special bolt is inserted into the steering mechanism. They most often try to modernize the hub assembly by manufacturing differential hubs (so-called unlockers). They can be made from the front hubs of Zhiguli or Moskvich cars. Be sure to cut off and sharpen the “ears”. If the bolts are very rusty, they are cut off with a grinder. But we must remember that the fitting of all elements on the axle should be as tight as possible.

I gleaned very useful information from this video, in the spring I’ll work on adjusting the reverse gear, re-drilling the hole, creating a larger lever, otherwise every time I pull the walk-behind tractor backwards on myself when I need to turn around.
Rustem Stryukov
That's it, I found it. The maximum tire pressure is 2.8 atmospheres. Thank you.
