Among the presented variety of units, the Neva MB 2 walk-behind tractor is very popular, but there are other equally popular models.
Getting to know the lineup
Motoblocks Neva are presented in different modifications, differing in configuration and technical characteristics. All models are capable of working with additional attachments, which significantly expands their functionality.

MB-1
The complete set of the Neva MB 1 walk-behind tractor differs from the previous model in the transmission. The motor is installed exactly the same, with a capacity of 6 liters. from. But the reducer here is "Multi-Agro", thanks to which the traction force on the walk-behind tractor has increased. The unit boasts improved cornering maneuverability due to the possibility of separate torque off for the right and left wheels.
The model is capable of processing the soil with cutters to a depth of 20 cm. At the same time, the working width has increased and is 86–127 cm. The weight of the unit is about 75 kg.

The equipment is equipped with a 5 liter fuel tank. There are 4 forward and two reverse gears. The depth of tillage with milling cutters is up to 20 cm. The working width is 86–170 cm.
MB-23SD
The owner of the MB-23SD model will be pleased with the pulling power of the 5 horsepower unit. This technique is equipped with a diesel engine of the Japanese brand Robin SUBARU DY series with a capacity of 5.5 liters. with., as well as an oil pump. The tiller is designed for continuous processing of large areas with difficult soil.

There is also a Neva Pro version. This entire range of motoblocks is equipped with a headlight, and the manual start of the motor is replaced by an electric starter. But owner reviews say that it is not worth overpaying for such improvements. The headlight is practically not needed, and the engine is easily started up from the recoil starter.

Motor-cultivators Neva
This light technique can be called the younger brother of motoblocks. Motorized cultivators perform the same processing functions, but only on light soil. The most popular models are MK-80, MK-100 and MK-200. These cultivators use a gasoline engine. The MK-80 model is equipped with a Japanese Subaru EY20 engine with a capacity of 5 liters. from. Model 100 has several modifications:

- MK-100-07 - Robin-Subaru motor;
- MK-100-09 - Honda GX120 motor.
Engine power from 3.5 to 5 liters. from.
The MK-200-N5.0 model is equipped with a 5 hp Honda GX-160 engine. from.

Conversion of the Neva walk-behind tractor into a multifunctional mini-tractor
Many craftsmen have learned how to assemble a mini-tractor from the Neva walk-behind tractor to expand the functionality of the equipment. It should be noted right away that a powerful unit is suitable for these purposes, preferably from 9 liters. from. Before starting work, you need to draw a kinematic diagram of the future homemade product. It will help you have an idea of what you are about to do. An example of a mini-tractor diagram can be seen in the photo.
Making a mini tractor starts with a frame. It can be welded whole or broken. The second option is more difficult, but benefits from agility. The frame is welded from the channel. For reinforcement, use a profile, pipes or corners. The one-piece construction is a rectangle with a web for rigidity. The fracture consists of two half frames. They are connected to each other by a movable unit - a hinge.
All frame elements are connected by welding. Headscarves made of thick metal are welded on complex joints. An additional bolt connection can be used to reinforce the frame. You can make a one-piece structure or a fracture according to the proposed drawings.
A motor is placed on the finished frame. If it is located in front, then leave the native width of the wheelbase of the walk-behind tractor. When the engine is rear-mounted, the native wheelbase is extended.
A steering column is required to operate. It is usually removed from a passenger car. Hydraulic control can be found from decommissioned agricultural machinery. It is more convenient to deal with it, especially if the frame on the mini-tractor is broken.
The driver's seat should be comfortable. He is also removed from the old equipment. The seat is fixed to the frame with an adjusting mechanism that allows you to change the height and angle of inclination.
Wheels on a mini-tractor are often set from a passenger car, but this choice is not always appropriate. Here you need to correctly determine the size. It is optimal when the diameter of the front wheels is 12-14 inches, and the rear wheels are 18 inches. If the wheels are incorrectly selected, the tractor will bury itself in the ground or it will be difficult to control the unit.
The brake and clutch pedal is usually connected to the engine block using cables. The gear lever must be brought out near the driver's seat so that it is convenient to reach it with your hands. After completing the assembly, the mini-tractor is run-in. Only then can the homemade product be loaded.
