Motoblocks "Neva": features and types

On the territory of Russia and the CIS countries, one of the most popular motoblocks is the Neva brand unit. It has been produced by the Krasny Oktyabr company for over 10 years. Over the years, it has proven its exceptional quality, efficiency and practicality.

The Krasny Oktyabr-Neva plant was opened in 2002 as a subsidiary of the largest Russian holding Krasny Oktyabr, which is known in Russia and abroad as one of the largest machine-building plants. The history of the company begins back in 1891. - it was then that a small enterprise was opened in St. Petersburg, specializing in a relatively young industry at that time - electrical engineering. A little later, the engineers of the plant, together with Soviet scientists, took part in the creation of the first power plant.

At the end of the 20s of the last century, the company merged with the Zinoviev Motorcycle Plant - from that moment a new milestone in the history of the enterprise began, the merger launched the production of motorcycles and auto parts, and in the 40s the plant began to work for the aviation industry (this is the direction that remains one of the main ones today). The production facilities of "Krasny Oktyabr" produce rocket and aircraft motors for such machines: Yak-42 aircraft, K-50 and K-52 helicopters.

In parallel, the company produces over 10 million engines for motorcycles and motors annually, and in 1985, a division specializing in agricultural equipment was created. It received the name "Neva" and became famous thanks to the release of motoblocks.

Motoblocks produced under the Neva trademark quickly gained popularity among gardeners and summer residents due to their practicality, reliability and the highest quality of assembly - according to estimates, the volume of rejects at this enterprise does not exceed 1.5%. This unit is distinguished by a rather high margin of safety due to the use of materials of the highest quality and the introduction of technological methods for their processing.

Motoblocks "Neva" have two speed modes forward and one in the opposite direction. In addition, a reduced row is presented - in this case, the belt should be thrown over to another pulley. The rotation speed varies from 1.8 to 12 km / h, the maximum weight of the manufactured models is 115 kg, while the device has the technical ability to carry loads up to 400 kg. To complete the motoblocks, the manufacturing enterprise uses DM-1K motors manufactured in Kaluga, as well as engines of such world famous brands as Honda and Subaru. The gearbox of the unit is a gear-chain, reliable, sealed, located in an oil bath.

The body is made of aluminum, it is lightweight and durable. Such a gearbox is capable of developing a force of more than 180 kg and can work effectively on any type of soil. A pleasant bonus is the ability to disengage the axle shafts, due to which it is possible to direct the drive to only one of the wheels, thereby greatly facilitating the process of controlling the walk-behind tractor.

Let's stop a little in more detail on the technical features of the Neva walk-behind tractors:

• maximum dimensions (L / W / H) - 1600/660/1300 mm;
• maximum weight - 85 kg;
• minimum pulling force on wheels when transporting cargo weighing up to 20 kg - 140;
• working temperature range - from -25 to +35;
• hodovka - one-sided;
• wheel arrangement - 2x2;
• the clutch is disengaged, the mechanism for engaging it is represented by a tension roller;
• gearbox - six-chain, mechanical;

• tire - pneumatic;
• the track is adjustable in steps, its width in the normal position is 32 cm, with extensions - 57 cm;
• cutter diameter - 3 cm;
• capture width - 1.2 m;
• digging depth - 20 cm;
• steering system - rod;
• used fuel - gasoline AI-92/95;
• type of motor cooling - air, forced;

The company "Neva" produces a wide range of motoblocks, the differences between which, in fact, are reduced only to the type of engine used. Here is an overview of the most popular modifications.

• "MB-2K-7.5" - the engine of the Kaluga enterprise of the DM-1K brand of various power levels is installed on the product: the semi-professional one corresponds to the parameters of 6.5 liters. s, and the professional PRO is equipped with a cast iron sleeve and has a power characteristics of 7.5 liters. with.
• "MB-2B" - This walk-behind tractor is equipped with Briggs & Stratton power engines. As in the previous case, they are divided into semi-professional and professional, the power parameters of the presented models are 6 liters. s, 6.5 liters. s and 7.5 liters. with.
• "MB-2" - This model is equipped with Japanese engines "Subaru" or Yamaha MX250, which differ in the upper camshaft. The modification is in great demand, as one of the most reliable in the world.

• "MB-2N" - has a Honda engine with 5.5 and 6.5 horsepower. These walk-behind tractors are characterized by the highest efficiency and increased torque. These features ensure long-term use and reliability of the entire unit, even in spite of its low power parameters.
• "MB-23" - this model range is represented by heavy motoblocks with rather powerful engines - from 8 to 10 l m. Subaru and Honda motors are most often used here, motoblocks are designed to work in intensive mode on any type of ground. It is noteworthy that the processing depth here is increased to 32 cm. In this line, the model "MD-23 SD" can be distinguished separately, which is a diesel one, therefore it stands out with the maximum draft force among all units of this series.

When choosing a walk-behind tractor, first of all, one should proceed from its power. So, if you work with the unit in the country from time to time, and the intensity of the work is low, then low-power installations with a parameter from 3.5 to 6 liters will do. This applies to plots less than 50 acres. Installations with a capacity over 6, l. s are optimal for intensive use, when there is a need for frequent and thorough tillage. For planting areas from 45 acres to 1 hectare, it is worth taking a closer look at models for 6-7 liters. s, and plots with a larger area require large capacities - from 8 to 15 liters. with.

Separately, it is worth talking about the differences between the Neva walk-behind tractor and other units. Many people compare the "Neva" with such domestic motoblocks of similar functionality as: "Cascade", "Salyut", as well as Patriot Nevada. Let's take a closer look at the description, similarities and differences of the models.

Many users argue that Oka is a cheap analogue of the Neva, the advantages of the Oka are low cost, while the Neva is dominated by such advantages as the power and high quality of American and Japanese motors. Among the disadvantages of "Oka" is often called an increased center of gravity, which leads to a constant overweight on the side, as well as heavy weight, so only a well-developed man can work with "Oka", and women and adolescents are unlikely to cope with such a unit.

It is up to the buyer to decide which walk-behind tractor to choose, however, before making a final decision, one should proceed not only from prices, but also from the practicality of the unit. Try to assess the size of your land plot, as well as the technical capabilities of the walk-behind tractor and your own skills in working with such mechanisms.

"Salut" is also called a cheap analogue of "Neva", however, the low cost entails quite significant drawbacks. As customer reviews show, "Salute" walk-behind tractors do not always start up in frost - in this case, you have to warm them up for quite a long time, thereby significantly increasing fuel consumption. In addition, factory wheels often fly off the rear fasteners in high vibration conditions, and the installation sometimes slips on virgin lands.

Neva has much fewer negative reviews, but users note that the need for Neva is not always justified - the choice of a suitable machine largely depends on the characteristics of the soil, the size of the cultivated land and the strength of the operator.

Ugra is another brainchild of Russian industry. It is a high quality device that works effectively on all types of soil. "Neva" and "Ugra" have approximately the same cost: in the range from 5 to 35 thousand rubles - if we are talking about used models, and new ones will cost at least three times more: from 30 to 50 thousand.

Among the disadvantages of "Ugra" are:

• lack of an additional set of cultivators;
• excessive vibration feedback to the steering wheel;
• small volume of the fuel tank;
• complete lack of smoothness;
• the device jerks off from a standstill.

All these shortcomings, all other things being equal, unequivocally tip the scales in favor of the Neva walk-behind tractors.

"Agat", like "Neva", is equipped with engines of American and Japanese production, and also includes engines made in China. According to farmers, "Agat" loses to "Neva" in terms of such parameters as: wheel height, low speed of movement when transporting goods on an attached trolley, as well as frequent leakage of oil seals.

Motoblock "Neva" is often used in combination with various types of attachments. So, for soil cultivation, not wheels, but cutters are installed on the unit, and their total number depends on the type of soil (on average, the kit includes from 6 to 8 pieces). For plowing the ground, a special hitch is used, and in order to ensure maximum adhesion of the installation to the ground, you should additionally purchase lug wheels.

For effective hilling of plantings, special hillers are used. They can be single and double row, they are also divided into adjustable and non-adjustable. The choice depends only on the characteristics of the cultivated land. Usually, with these devices, metal wheels of an increased size are used, thereby increasing the agrotechnical clearance.

Special planters can be attached to the Neva walk-behind tractor, with the help of which you can sow a plot with seeds of vegetables and grain crops, and also often purchase special nozzles designed for planting potatoes - such devices greatly reduce the time and effort spent on sowing.

A potato digger will help to harvest root crops. Usually, vibration models are attached to the Neva walk-behind tractor, which do a fairly good job of processing a small section of the landing area. The principle of operation of potato diggers is simple: using a knife, the device lifts a layer of earth along with root crops and moves it to a special grate, under the action of vibration, the earth is sifted, and peeled potatoes on the other hand fall to the ground, where the owner of the land plot collects it, without spending significant effort. The capacity of such a digger is approximately 0.15 ha / hour.

For hay harvesting, it is worth purchasing mower attachments, which can be segment or rotary. Segment mowers are made of rather sharp steel, they move in a horizontal plane progressively towards each other, they work best with grasses on level ground. Rotary devices are more versatile. The working tool here are knives mounted on a continuously rotating disc. Such adaptations are not afraid of any irregularities in the soil, they will not be stopped by either grass or small bushes.

In winter, the walk-behind tractor is used to clean the local area from snow - for this, snow blowers or snow plows are attached to them, which allow you to effectively clear fairly large areas in literally a matter of minutes. But for garbage collection, it is worth giving preference to rotary brushes with a working width of 90 cm. If it is necessary to move loads, a trailer-cart is attached to the Neva walk-behind tractors, which moves at a speed of 2.2 km / h and has a carrying capacity of 400 kg. Typically, such a cart is equipped with a seat for the operator, a reliable hitch and a braking system.

Caring for a walk-behind tractor is simple: the most important thing is that it is constantly clean and dry, while it should be located exclusively in a horizontal position supported by an additional wheel or a special stand. When buying a walk-behind tractor, first of all, you need to run it in for 1.5 days. The machine should be operated as sparingly as possible at full throttle, while avoiding excessive loads. In the future, all that is required for the walk-behind tractor is a periodic inspection, which includes a thorough check:

• the amount of oil;
• tightening strength of all threaded connections;
• general condition of the main protective elements;
• tire pressure.

We are accustomed to the fact that agricultural machinery works in the spring-autumn period, however, even in winter there is work for the Neva motor-blocks - cleaning and clearing the territory from snow obstructions. With the help of a snow blower, you can remove all fallen or accumulated snow in a few minutes, instead of wielding a shovel for hours. However, if everything is clear with operation in warm weather, then the winter use of walk-behind tractors has its own characteristics.

As follows from the instruction manual, first of all, the device should be prepared for operation in frosty conditions. - for this, it is necessary to change the oil in a timely manner, as well as the spark plugs - then the viscosity of the composition will be less, which means that starting the engine will become easier. However, even this does not always help to start the engine. To avoid such an unpleasant phenomenon, you need to store the unit in a heated room (for example, in a garage), and if this is not possible, then before starting it you need to cover it with a warm blanket, and on top with a woolen blanket. Be sure that after these simple manipulations, your car will start as easily and simply as in the summer. If necessary, add some ether to the carburetor - this way you can also make it easier to start the engine.

Owner reviews point to the many advantages of Neva walk-behind tractors.

• Imported engines of world famous companies Honda, Kasei and others, which are distinguished by extremely high efficiency and excellent motor life. Such a device allows you to use the walk-behind tractor even in very unfavorable weather conditions.
• A functional and at the same time simple system for switching the speeds of the motor unit. Thanks to this, you can choose your optimal speed for each type of work. Their total number depends on the type and modification of the device (for example, the first gear is used on the most problematic and hard soils, and the third - on an excavated piece of land).
• The motor-block "Neva" is successfully combined with attachments of any type: with a plow, a mower, a snow blower, a cart and a rake. All this allows the installation to be used at any time of the year.

• The motoblock allows you to set any position of the steering wheel, and if a lug is also used in conjunction with the installation, then the steering wheel can be quite effectively controlled so as not to spoil the created furrow.
• The units manufactured by Krasny Oktyabr have a lightweight, but at the same time, robust case, which effectively protects the entire device from gas, dust and mechanical damage. To reduce the vibration load, the housing is often reinforced with rubber pads.
• It is noteworthy that the transportation of such installations is possible on any vehicle, while the manufacturer promises a guarantee for its equipment and long-term service.
• If one of the spare parts of such a walk-behind tractor fails, there will be no problems with the purchase of components - they can be found in any store. Spare parts for imported models often have to be ordered from the catalog and wait quite a long time.

Of the shortcomings, users indicate the following points.

• Lightweight Neva models do not work well enough in the “plow” mode, so they have to additionally attach a weighting agent (in this case, the plowing depth is 25 cm).
• Despite the fact that the model is quite compact, you can often buy a smaller analog.
• The weight of some models reaches 80-90 kg, which significantly limits the circle of persons who can handle such a tool. However, you can purchase the MB-B6.5 RS Compact model.
• Many gardeners believe that the cost of Neva walk-behind tractors is overstated. In this case, it should be borne in mind that the price of products of this brand depends not only on the manufacturer, but also on the pricing policy of the trade enterprise. That is why users in most cases recommend giving preference to buying a product directly from the manufacturer through their official website.
