User manual

The walk-behind tractor and attachments require regular preventive maintenance. Most units have imported power plants, they should be repaired at service centers. On your own, you can only drive the unit at idle, pouring fresh oil into it.

Five hours will be enough to start the engine, warm it up. At the same time, it is not recommended to subject it to heavy loads at the very beginning.

The first few days the walk-behind tractor will need to be loaded only by 50% so that all nodes fit properly. After these procedures, the oil is completely drained, washed with a special composition. After that, a good semi-synthetic oil 10W30 or SAE30 is poured in the amount of 650 ml.

The amount of oil for the "Neva" will need approximately one and a half liters. If the engine starts to stall, smoke appears, then the unit should be sent to the service station, it is better not to disassemble anything on your own.

Carburetor adjustment is done on the Neva unit at the factory.

If the engine has been running for more than one year, then the following actions should be performed.

The screw on the carburetor, which is responsible for the composition of the mixture, is tightened to failure, this will lead to a maximum increase in the fuel content in the combustible mixture.
The engine starts, the mixture is leaner, the screw is turned out, which regulates the amount of mixture. Thus, you can find the optimal mode of operation. All these operations can be done when the motoblock candle is clean, it must be in normal working condition.
The unit should sometimes be “driven” at high speeds, no more than ten minutes, after carrying out such operations, the engine will work better.
If there has been a displacement of the centrifugal regulator, then it will need to be returned to its original position. To do this, unscrew the M8 nut, pull the damper all the way to the left. Then this location should be fixed.

Sometimes the belt comes off the pulley. If you follow the instructions, you will need to adjust the tension mechanism. Often the old belt is simply removed, a new one is put in its place.

The pulley is adjusted in this way:

the engine is attached with bolts;
by adjusting the bolts, you can deflect the engine in the right direction;
looking for the desired location when the belts are tensioned correctly.

Checking the belt tension is very simple: just press with your finger to see how much it deviates. Usually a deviation of the order of one centimeter is sufficient.

The plow can also be adjusted. The setting is done in two phases: the walk-behind tractor is placed on the load hooks, two linings are placed under them. The unit is fixed without deviations. Then the setting of the plow "Neva" is done in such a way that the bar is close to the soil, the stand must be vertical.

To make a universal hitch with two nuts, you can only find the desired angle empirically, you will have to do several test tests. At the end, the debugging of the angle of the dump of the earth, which comes out from under the cutting edge, is done. A simple operation, it is done simultaneously with the adjustment of the rack itself.

You will learn how to replace the belt on the Neva MB 2 walk-behind tractor in the next video.

One of the largest manufacturers of motorcycle equipment for gardeners and gardeners in Russia and the CIS countries is the Red October - Neva company. The company owes its leading position in the market to the Neva walk-behind tractor, the assembly of which the company mastered more than 10 years ago.

During its existence, the Neva acquired a number of modifications and acquired a variety of attachments. Due to this, the walk-behind tractor is able to perform a wide range of work, both in tillage and in animal husbandry, on a small scale. This makes this type of equipment very popular in the conditions of personal subsidiary plots.

The history of the creation of the motoblock "Neva"

Krasny Oktyabr - Neva was founded in 2002 and is a subsidiary of JSC Krasny Oktyabr. This machine-building plant begins its history back in 1891 in St. Petersburg.

At that time, the company worked in a young, developing branch of industry, electrical engineering. Participated in the construction of the first power plant of the same name in the union. In the late 1920s, after a merger with the Zinoviev Motorcycle Plant, the production of automotive parts and L-300 motorcycles began.

Since 1940, "Red October" began to work for the aviation industry, in this direction the company continues its activities to this day. Aircraft and rocket engines, as well as their components, for such famous machines as the Yak series of combat aircraft, K-50 and K-52 helicopters were and are being produced in the workshops of this enterprise.

In parallel with the aviation industry, over the years of its existence, the plant has been developing and producing more than 10 million engines for mopeds and motorbikes. In 1985, he mastered the production of mini agricultural machinery in the person of the hero of our story, the Neva walk-behind tractor.

The walk-behind tractor receives its modern rebirth in 2002, when a specialized subsidiary "Red October - Neva" is created. Now the company is engaged in the development and production of 4-stroke engines, walk-behind tractors, cultivators and attachments.

Technical characteristics of the Neva walk-behind tractor

Motoblocks "Neva" have gained popularity among the population, primarily for their reliability and build quality, the percentage of defects in the enterprise does not exceed 1.5%. The machine has a good margin of safety, thanks to high-quality materials and high-tech processing methods.

The device has 2 speeds forward and 1 back, there is also a reduced row, for this you have to throw the belt onto another pulley. Travel speed from 1.8 to 12 km/h. The heaviest produced model weighs 115 kg, and the weight of the transported cargo can be up to 400 kg.

Motoblock engine "Neva"

To complete its walk-behind tractors, the Krasny Oktyabr-Neva company uses DM-1K engines made in Kaluga and engines of famous world brands Honda, Subaru, Briggs & Stratton of various capacities.

Reducer of the motor-block "Neva"

The Neva gear-chain reducer, sealed, in an oil bath, is characterized by a reliable design. Lightweight and durable body made of aluminium. Such a gearbox develops a force exceeding 180 kgf and is able to provide reliable operation on all types of soil.

A nice addition is the mechanism for disengaging the axle shafts, which allows you to direct the drive to only one wheel, thereby greatly facilitating control.

Transmission motoblock "Neva"

Torque from the engine to the gearbox is transmitted using a V-belt drive with a tension roller. This design is time-tested, not expensive to perform, simple and reliable. If the walk-behind tractor hits an obstacle during operation, the belt will simply begin to slip, thereby protecting the engine and gearbox elements from damage.

Overview of models of motoblocks "Neva"

All modifications of the MB-2 walk-behind tractor differ in essence, only in the installed engine. The rest of the design remains unchanged, only minor improvements are possible.

Main modifications:

MB-2K- the letter K in the name means that this model is equipped with engines of domestic Kaluga production "DM-1K" of various capacities. Semi-professional 6.5 hp and professional with a cast-iron sleeve 7.5 hp.
MB-2B- here the letter after the deuce indicates that the walk-behind tractor is equipped with Briggs & Stratton professional power plants. These engines are also divided into semi-professional and sleeved professional ones with the PRO prefix in the name. Power models 6; 6.5; 7.5 HP
MB-2S- engines of the well-known Japanese company Subaru are aggregated for this modification. These are reliable, professional, overhead camshaft EX-17D 6hp units. and EX-21D 7hp
MB-2N- with a Honda engine with a power of 5.5 and 6.5 hp. These engines use the latest developments of the legendary Honda, have excellent efficiency and high torque. Due to this, despite the low power, they provide durable and reliable operation of the entire unit.
MB-23- a series of heavy walk-behind tractors with powerful from 8 to 10 hp. engines. In the name, the letter after the numbers, like the middle brothers, indicates the engine manufacturer - Subaru, Honda, Briggs & Stratton. The machines are designed for long-term, intensive work on any type of soil, the working depth of which, on these machines, is increased to 32 cm.

Of particular note is the only model MD-23SD with a Subaru diesel engine with a power of 5.5 and 7 hp. Despite the low power, due to the fact that it is a diesel engine, the model is the most high-torque among the MB-23 line.

Attachments for Neva walk-behind tractors

For soil cultivation on the Neva walk-behind tractor, cutters are installed instead of wheels. Their number, depending on the type of soil, can reach eight pieces. The basic set includes 4 cutters, additional cutters are purchased separately.

For plowing with the help of a walk-behind tractor, you will have to purchase a plow and a special hitch-mount. You will also need metal wheels with lugs for better grip on the soil.

For hilling single-row and double-row hillers are used, which can also be divided into unregulated and adjustable. It is necessary to choose a hiller based on the quality and composition of the soil. With hillers, metal wheels of increased diameter with lugs are used, this allows you to increase the agrotechnical clearance.

For the mechanization of planting potatoes using the Neva walk-behind tractor, it is recommended to use potato planters KS-1, KS-1A, KST-. This not only facilitates the planting process itself, but also creates the necessary conditions for further inter-row cultivation and harvesting with the help of attachments. This is facilitated by an even landing and a fixed row spacing. The average productivity of such planters is 0.2-0.25 hectares per hour, the distance between the tubers is maintained at 25-30 cm, and the width between the rows is regulated by the gauge of the unit within 60-70 cm.

There are two types of potato diggers on the walk-behind tractor we are considering:
fan and vibrating (roaring type). The use of both of them is quite justified in small areas and quite cope with their duties.

Fan diggers for deepening and cutting the soil have a solid metal knife at the base, and metal rods fan out from the knife. The layer of earth raised with a knife is sifted through the rods, and the potatoes are delayed and rise to the surface. The productivity of diggers of this type is approximately 0.15 hectares per hour.
Vibrating or screening potato diggers. The main working elements of such a hinged are: a plowshare and a vibrating grate for sifting the soil. The ploughshare raises the soil with potatoes onto the grate, and the grate with a belt drive from the walk-behind tractor sifts the ground leaving clean potatoes on the surface. For the Neva, it is recommended to use models KKM-1, KMU-3, KK-6 and others. The average productivity of such equipment is approximately 0.2 hectares per hour.

Mowers for the Neva walk-behind tractor also come in two types:

Segment, with shearing knives made of hardened durable steel, moving forward in a horizontal plane. They work best on even surfaces, with cereal, evenly standing herbs. For example, the KN-1.1 mower, the cutting width reaches 110 cm, and the productivity is approximately 0.35 ha per hour.
Rotary- have recently become increasingly popular, displacing segmented mowers from the market. The working elements here are knives mounted on a rotating disk. Such mowers are not afraid of small surface irregularities, as well as dense grass and small shrubs. The Kaluga mower "Zarya" and "Neva-KR-05" manufactured by the company "Red October - Neva" are vivid examples of this family.

Especially for the Neva, the SMB-1 auger snow blower is produced at the factory native to the walk-behind tractor. The auger is designed in such a way that the snow moves from the edges to the middle, to the nozzle. The direction of snow ejection is regulated by turning the screen of the snow blower, the skids on the body regulate the cleaning height.

The communal rotary brush is mainly used for garbage collection. Capture 90 cm wide is established at an angle to 90 degrees. Maximum productivity up to 2200 m/2.

Cart trailer - the carrying capacity of such a cart reaches 400 kg. Equipped with a driver's seat, brakes and a reliable hitch.

Among the domestic equipment for gardening, there are representatives who have firmly settled in the minds of landowners as the most versatile and unpretentious models. Among them, the Neva MB 2 K walk-behind tractor stands out - a machine with history and a lot of fans. We offer to study the description of the model, its features and advantages.

Configuration options and design of the walk-behind tractor

Today, the Neva MB 2 walk-behind tractor enters stores in several configuration options:

The MB 2 K model is equipped with a motor with a long service life and modest fuel consumption;
The 2MB 2 B unit is equipped with various imported engines with different power reserves;
The MB 2 S model is equipped with expensive professional engines from Subaru.

For large areas, it is worth choosing more powerful equipment, and for small areas, the budget version of the MB 2 walk-behind tractor is quite suitable. Be that as it may, the manufacturer of the equipment categorically does not equip it with Chinese motors with low-quality candles and other important details.

The design of the Neva MB 2 K walk-behind tractor includes a gear-chain type gearbox placed in an aluminum case. It is perfectly combined with a powerful motor, and allows the owner to operate the unit in one of 4 forward and two reverse speeds. At the same time, starting from a place in second or third gear has practically no effect on the operation of the candles.

Working in first gear, the device produces a thrust of 180 kgf. This guarantees trouble-free use of the model for plowing, hilling and cultivating heavy soil. The standard speed of the unit with a trailer reaches 10 km / h, however, with a slight upgrade, this figure can be increased to 12 km / h.
A feature of the walk-behind tractor is its light weight. It is a little less than 100 kg, which allows two adult men to load it onto a car trailer.

The engine of the unit - we study the "heart" of the machine

A reliable motoblock motor is the key to its smooth operation. That is why this element is worth studying in more detail. Its features include:

Depending on the configuration, the walk-behind tractor can be equipped with different single-cylinder 4-stroke engines;
The engine is attached to the frame with special reinforced bolts;
The transmission of rotation to attachments is carried out by means of a pulley;
Starting work with the unit, the motor must be adjusted using the air damper. In doing so, you must adhere to the instruction manual.

Without completing this simple procedure, the owner of the model is in danger of such troubles as a broken clutch cable. Often, beginners notice that the speed is floating in the engine. The reason for this lies in the need to adjust the gearbox. You can also find instructions for the correct setting in the instructions for the walk-behind tractor.

One of the advantages of the motor of the unit is the absence of the need for frequent purchase and replacement of spare parts - paired with low fuel consumption, this makes the walk-behind tractor one of the best representatives in the price-quality ratio.
