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 model range
Motoblocks Neva are represented by different modifications, differing in configuration and technical characteristics. All models are able to work 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. With. But the gearbox 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 ability to separate the torque off of the right and left wheels.
The model is able to process 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 mass of the unit is about 75 kg.
MB-2

The walk-behind tractor weighs about 100 kg. The cutters work the soil to a depth of 20 cm. The working width is 86–170 cm. A unit with 6 horses on light soil will pull up to 8 cutters. On clay soil, the number of cutters is reduced to 6 pieces.
MB-23B10
The Neva MB 23 heavy walk-behind tractor is equipped with a Briggs & Stratton gasoline engine. Engine power is 10 liters. With. The unit is designed for heavy loads, and is able to grind virgin soil with milling cutters. A walk-behind tractor with 10 horses will easily process even clay soil with 8 cutters. The equipment is equipped with a fuel tank of 5 liters. There are 4 forward and two reverse gears. The depth of tillage with cutters is up to 20 cm. The working width is 86–170 cm.

The walk-behind tractor is designed for continuous processing of large areas with difficult soil. The unit weighs about 115 kg. The depth of tillage with cutters is up to 20 cm, and the working width is 86–168 cm.
There is also a version of Neva Pro. This entire range of walk-behind tractors is equipped with a headlight, and the manual start of the motor is replaced by an electric starter. But the reviews of the owners say that it is not worth overpaying for such improvements. The headlight is practically not needed, and the engine starts easily from a manual starter.

Motor cultivators Neva
This lightweight technique can be called the younger brother of walk-behind tractors. Motor cultivators perform the same processing functions, but only 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 power of 5 hp. With.

Engine power from 3,5 to 5 liters. With.
The MK-200-H5,0 model is equipped with a 160-hp Honda GX-5 engine. With.

Alteration 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. With. 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 going to do. An example of a mini-tractor circuit can be seen in the photo.
The manufacture of a mini-tractor begins with a frame. It can be welded whole or broken. The second option is more difficult, but benefits from maneuverability. Weld the frame from the channel. For reinforcement, use a profile, pipes or corners. One-piece construction is a rectangle with a jumper for rigidity. The fracture consists of two half-frames. Between themselves, they are connected by a movable node – a hinge.
All elements of the frame are connected by welding. At complex joints, thick metal scarves are welded. To strengthen the frame, you can additionally use a bolted connection. It is possible to make a solid 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. With the rear engine, the native wheelbase is expanded.
You will need a steering column to steer. It is usually removed from a passenger car. You can find hydraulic control from decommissioned agricultural equipment. It is more convenient to deal with it, especially if the frame on the mini-tractor is broken.
The driver’s seat must be comfortable. It is also removed from the old technology. The seat is fixed to the frame with an adjustable mechanism that allows you to change the height and angle of inclination.
Wheels on a mini-tractor are often put 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 dig into the ground or the unit will be difficult to control.
The brake and clutch pedal is usually connected to the engine block using cables. The gear lever must be removed near the driver’s seat so that it is convenient to reach out with your hands. After the assembly is completed, the mini-tractor is run in. Only after that, the homemade product can be loaded.
