Review of NEVA MB-3 motor blocks. Changes, operating instructions

Motoblock Neva MB-3

NEVA MB-3 is the product of the automobile plant in St. Petersburg “Red October”, which is involved in the production of household equipment. The model considered is actually seen as the successor to the popular NEVA MB-3 engine note. The car has absorbed the best of the predecessor and also received many innovations. In general, the motoblock has become more maneuverable and more economical, as well as functional and convenient in lon g-term operation. At the same time, the service costs remained at a traditional low level, although the use of imported components.

General information, purposes and design features

The MB-3 Walk-Hinge tractor is intended for the processing of land and farm plots and is also in demand among gardeners and supply companies. Allows you to do plowing, cultivation, hilling, mowing and other types of work. The tractor of the walk behavior is equipped with outstanding skills, including outside of road traffic and delayed soil.

Like the predecessor of MB-2, the new MB 3 motor block regularly receives different updates. The developers are gradually improving the design of the tractor of the walk behavior to keep up with the competitors. We draw attention to the fact that there are three modifications to the NEVA MB-3 family today: These are versions of MB-3B-6.0, MB-3S-Spr 6.0 Pro and MB-3.0 Pro. These motoblocks differ mainly from the performance and the support of a certain attachment device. In general, however, it must be admitted that the owner of the most expensive configuration (MB-3C.0 Pro) does not win much compared to the basic model (MB-3B.6.0) because the motblocks have an identical design. This means similar advantages and disadvantages.

We find that all motoblocks are equipped with imported engines from Briggs & Stratton and Subaru. Every motor change is a good choice. It is worthwhile to appreciate the developers that he has denied the use of Chinese power plants such as Lifan, which are significantly inferior in every respect, including reliability.

The list of the main structural elements of the NEVA MB-3 family of the NEVA family includes a gear transmission enclosed in the aluminum housing. We also notice a mechanical box with six speeds in which two four speeds move forward, and the other two are responsible for the reverse gear. It is worth noting that the first gear creates a traction of 180 kgf and does not exceed the speed 2 km/h. In this mode, it is very comfortable to plow and calm the floor and cultivate the soil. The performance of the tractor of the walk is such that it can be distributed over 12 km/h. The traction supply can already be seen in the lower revolutions, so that there should be no problems with the transport of heavy loads. The mass of the device exceeds 100 kg. Nevertheless, the technology has compact dimensions. Thanks to this, the walk tractor can be transported in the trunk of a car. The main thing is that the trunk volume is more than 400 liters.

Useful experience of the owners of the NEVA Motoboblock MB-3

Reviews about the NEVA Motor Block MB-3 on the Internet are mostly positive. Users notice the improved properties of MB-3 compared to the previous model and the high-quality operation of the device. Vitaly:

“In general, the impressions of MB3 are only positive. I had to get used to the start of “Hot”, but got up – he just opened the air damper and then everything was fine. I liked the pens – comfortable because they are set in height. At first I did not like that the engine has only 4 revolutions, there is no such smooth setting as the “gas” by car, but the performance and revolutions liked both when plowing as well as when idling. In about six hours he plowed virgin countries four acres, and he went through the walk twice. On a solved country it is fine, very cheerful, the driver only control and you have to turn the steering wheel. “


“Three years ago I bought a NEVA MB-3S Summer Pro, the EX17 Robin Subaru Motor.

If you compare it to the NEVA MB-2, my MB3 focus is below. The defects: a current on a motor disc. A new belt disk is required to install Active Schonded. There is no rising pen. I used MB3 to MB3 for 7 years. At MB3 there are 3 gears + vice versa, this is more convenient than in MB2. I am quite satisfied with the engine block. “
