Device of the motor-block Neva MB2
As well as any other special equipment, the motor-block consists of a number of in common working components. Consider the main parts that make up this equipment:
- the engine (due to this unit, torque is generated, which is transferred to the axle),
- transmission (this component allows you to determine the direction of application of torque, as well as the number of engine revolutions),
- gearbox (this unit allows you to evenly distribute the torque on the leading parallel axis),
- gears (allow you to redirect the torque from the engine to the gearbox and the axle),
- wheelbase (due to the axis, the device is moved along the surface, there are two-wheel and four-wheel models),
- steering mechanism (due to this mechanism, it is possible to control the motor-cultivator or motor-block Neva).
In this case, the main components of the motoblock were considered, but also in its device there are a number of additional mechanisms and parts.
Important. In order for this apparatus to improve the soil properly, it is necessary to constantly monitor the performance of the power units, as well as auxiliary mechanisms, in addition, timely maintenance is carried out (replacement of consumable elements).
Motoblock Neva MB2 engine Subaru
It is not a secret for anyone that not only the Briggs Stratton engine is mounted on this type of special equipment. Also, these units can be equipped with engines of the company Subaru. Consider the main characteristics of these devices:
- higher power
- lower fuel consumption
- higher turnovers
- increased service life of the motor.
All these qualities make it possible to significantly upgrade the motoblock scheme, which also allows you to extend the service life of the machine.
Important. If a motor is being replaced, it is also necessary to subject all other components to appropriate maintenance in order to carry out comprehensively the entire replacement of consumable items.
Technical characteristics of the motor-block Neva MB2
This type of special equipment, as a rule, is distinguished by the following technical characteristics:
- six horsepower and 4.5 kW,
- 3.8 liters fuel tank
- three gears (2 front, one back),
- working volume of 205 cubic centimeters,
- the engine takes 92 and 95 gasoline,
- engine speed (23-42 first gear, 89-160 second).
A trailer for a motor-block brand Neva MB 2 is installed on the device, as well as other attached equipment for processing and cultivating the soil.
Important. For the Neva MB 2 tiller, there are a large number of attachments (cutters, plows), this is due to the widespread model.
Hinged equipment for the motor-block Neva MB2
Depending on the tasks, the following equipment can be hung on these devices:
- grousers (used for plowing),
- milling cutters (used for hilling),
- plow (usually used for loosening).
In addition to the usual fixed plow for motoblock Neva, the plow can be used as a trailed component to simplify the tillage procedure when loosening.
Important. It is also possible to equip the apparatus with a tank of water and a liquid sprayer in order to carry out uniform watering.
This type of auxiliary components, allows to plow the soil. Processing is performed by special shovels, which are connected in one chain. Due to such a device you can quickly plow the soil of a large area. Devices are hung on the device using a standard hitch with a walk-behind tractor.
These mechanical elements are usually used when hilling. Devices are customizable. This type of fixtures can be hung in two rows, which allows two furrows to be cultivated at once. In this case, it saves time and energy costs.
This type of tool is a conventional mounted plow, which is used to loosen the soil. After a piece of land has been traversed, you can immediately plant the plants in the cultivated soil. These devices are hung as trailers. When processing should be ensured that the plow does not go to the side.
Features of operation of the motor-block Neva MB2
When using the brand tiller, one should take into account a number of nuances and points that require attention, namely:
- you should know in advance the working volumes, as well as how much oil is in the engine block,
- to clarify what kind of gasoline to fill in, since the service life of equipment depends on the quality of the filled fuel,
- it is important to take into account periods of maintenance,
- you should know when to carry out a full comprehensive service,
- during operation, it is not recommended to be very zealous and keep the device running for a long time,
- Immediately after the purchase, it is required to conduct a run-in on non-equipped special equipment so that all the parts get used,
- after maintenance, it is also not recommended to immediately load the equipment.
You should also take into account the fact that you should not allow the device to work on fuel residues, as over time, impurities accumulate in the tank, which can damage the engine and reduce its service life.
Important. This type of special equipment is different from other devices, so the maintenance stages are not set by mileage, but depending on the watches, which is why the time of use should be monitored carefully.
How much oil should be poured into the engine
It should be understood that in tillers, the oil is subjected to periodic replacement not only in the engine, but also in the gearbox and transmission. Consider in more detail the amount of this consumable:
- 1.3 liters of engine oil should be poured into the engine,
- the gearbox is filled with oil on a special dipstick,
- in the transmission also the oil is poured in accordance with the probe.
After pouring the lubricant into the motor, it is required to check its level. It should be located between the minimum and maximum.
Important. If there is a lack of lubrication, the engine's life is drastically reduced, with an excess of oil, there may also be a reduction in the working life, since this fluid is not subjected to compression.
What gasoline is suitable for the motorcycle block Neva MB2
To walk treadmill for a long time to work without complaints, it is recommended to use high-quality fuel. Here 92 or 95 petrol is poured. Experts recommend periodically increasing the octane number if AI 92 is used, which allows cleaning the power plant from deposits. The manufacturer recommends pouring gasoline with a high-octane number not more than two times per season, provided that the tiller is used on a regular basis. If this type of technology is used less frequently, then we can limit ourselves to pouring 95 fuel once a season.
Important. It should not be too often to alternate the fuel, and in addition to change the place of its purchase, as the content of impurities in the fuel may differ at different gas stations.
Motoblock Neva: attachments - potato planters
We mentioned the canopy for the motoblock, which helps us to dig up potatoes after its ripening. But you can not only collect potatoes with the help of the motoblock, but also plant it before. For this there is a potato planter.
For the Neva motoblock, take a potato planter KSM-1. A good device for planting tubers at their summer cottage. In addition to the motoblock, the Neva is also suitable for the Cascade, Mustang and ZIRKA motoblocks, but unlike the last two, the potato planter does not need an adapter to connect with the Neva.
Koma KSM-1 to the motoblock Neva fit KSN-1. This single-row device is good in that it is suitable for all types of tillers: light, medium and heavy.
Standard reversible plow for motoblock Neva
If you use your plow to plow the land before planting crops, instead of the standard mounted plow, you can hang a reversible plow on the Neva walker. The superiority of this variety is that the plow has two bodies, due to which there are no gaps in the processing of the soil.
The reversible plow is mounted on the 100 kilogram units, more weight is possible. Of course, if the tiller is a bit smaller, you can always hang the weighting agent. It is good to buy such canopy to the Neva motor-block. When plowing, Zykov's plow covers the soil to a width of 19-23 cm. In addition to the Neva, the reversible plow can easily be connected to the Bison, Salyut and ZIRKA motor-blocks.
How to make a universal rake to a walk-around with your own hands
It seems that there is no simpler design of a motor-block in its construction than a rake. So much the better for those who want to make them on their own and not spend money.
Of course, provided that you have materials for this and a welding machine. For the manufacture of homemade rakes from the motor block, you must take a metal pipe and strong rods in the form of half rings.
For pipes easily fit water pipe (if available). Rake teeth, we must make a height of 700-800 mm. It is necessary to fasten the rods along the entire length of the pipe with a welding machine.
The rake should be coupled with the walker with the adapter. If you wish, you can get what is shown in the photo above. By the way, if you want to make such a rake, you can take the drawbar from the trailer if you do not need it, and slightly rearrange what is behind the seat.
