Peculiarities

Motoblocks Neva MB-2 have a number of technological features, thanks to which they have earned popularity among buyers.

Reliable engine. Engines of all modifications of the Neva MB-2 walk-behind tractor are characterized by reliability due to the following features:

• the presence of a ball bearing in the main crankshaft supports ensures smooth operation of the power plant;
• automatic decompressor;
• reliable air filter with double cleaning element;
• low noise and low fuel consumption;
• a special ignition system that allows you to start the engine under any conditions.

Additional set of gears. The number of gears in different walk-behind tractor models can be different: two forward and one reverse (2+1) or 3 forward and 1 reverse. However, they can be increased by rearranging the belt on a double-ribbed pulley. A large set of gears allows you to choose the optimal speed for performing certain types of work.

Rotating shield. Necessary for ease of rearranging the belt. To perform the operation, you simply need to turn the holder, lift the shield and rearrange the belt.

Wheel separation. This function is needed for easy reversal of equipment at the end of a row. To do this, press the left or right lever and easily turn the unit in the desired direction.

The gear shift lever is located on the steering wheel. It is ergonomic and easy to switch.

Adjustable steering wheel in vertical and horizontal planes. You can adjust the steering wheel to suit the operator’s height and turn it to the desired angle, for example when working near a fence or other obstacles.

Cultivation with 4-8 cutters. Neva MB2 walk-behind tractors are capable of processing various types of soil using 4 or 8 cutters. When cultivating light soil, 8 cutters can be installed. As a rule, additional cutters are installed to increase the width of the soil, as well as to ensure the stability of the unit.

The main differences between the classic gearbox and MultiAgro.

The classic has been produced by the plant for more than 30 years:

— 4 forward gears / 2 reverse

— function of unlocking the left wheel of the walk-behind tractor

— Gear shift on the gearbox

- gear-chain

MultiAgro is a patented, unique development

— 6 or 8 forward gears / 2 or 4 reverse gears

— function of unlocking both wheels

— Gear shift on the steering wheel

— gear-chain reducer

Advantages and disadvantages

Like any equipment, the MB-2 walk-behind tractor has its advantages and disadvantages.

Positive sides:

• works the soil well and plants root crops without cutting them;
• low fuel consumption;
• can work at any time of the year and in any weather;
• versatility (aggregates with any additional equipment);
• high degree of reliability;
• maintainability and availability of spare parts;
• excellent build quality.

Negative sides:

• poor balancing . With a weight of about 100 kg, the walk-behind tractor for soil cultivation does not have enough mass in the center or in front of the structure. When working with such a mass, even an experienced user’s hands quickly get tired. On uneven surfaces, equipment regularly falls on its side;
• the small distance between the wheels and their small diameter make the MB-2 model unstable;
• When working on virgin soil, the cutters do not work satisfactorily . The walk-behind tractor either jumps out of the ground or buries itself. It turns out that processing occurs in “waves”;
• inconvenience in replacing cutters . It’s difficult to keep the weight of 100 kg when replacing a dirty hub with heavy cutters.

You can get acquainted with all the advantages and disadvantages of the Neva MB-2 walk-behind tractor by watching the video:

However, according to owner reviews, the advantages outweigh the disadvantages.

Reviews and opinions of owners

Let's take a look at the opinions of farmers who have already purchased this model.

Ilya, Ryazan, Russia:

“I want to share my conclusions about Neva MB2. I bought it for my father, so I’ll say that the walk-behind tractor is very convenient, despite the power, the dimensions are such that you can easily drive it on loose soil - it doesn’t get bogged down, maneuvers well, and is quite light. I worked with MB2-B MultiAGRO (I/C 6.5) on alumina - I did it easily, and my retired father uses it without any problems. A good, nimble walk-behind tractor will go through and turn around where others won’t fit!”

Vladimir, Ufa, Russia:

“I bought myself” MB2-N MA CX200. I’ll immediately describe the advantages: the first is the management. You can hold it with one hand without applying force, the walk-behind tractor does not fall over. I hooked up the trailer and the blade and the snow blower, everything works! The second plus is the start. Starts up very well and smoothly. I liked the fastenings, they seem like a small thing, but nothing is loose or loose. I’m not drawing any conclusions yet, I’m waiting for spring, then I’ll check how it works. Still, I recommend Neva for purchase, it’s a cool piece of equipment.”
