Motoblock "Neva" with a Subaru engine is a popular unit in the domestic market. Such a technique can work the land, which is its main purpose. But when installing additional equipment, the device becomes suitable for performing various tasks and in another direction, and a motor from a Japanese manufacturer provides uninterrupted and stable operation.
Design and purpose
Despite the fact that this device is produced in domestic conditions, it uses imported spare parts and components. This affects the cost of the walk-behind tractor, but at the same time it remains affordable for most users. All units and spare parts are of high quality, with long-term operation there are no problems with them.
The engine is on a wheelbase with one axle and has proven itself in a variety of jobs in extreme conditions . With the help of a walk-behind tractor, you can process personal plots and vegetable gardens. And also when using special attachments, the walk-behind tractor can be used for snow removal, harvesting and other work.
The walk-behind tractor is distinguished by great functionality, but belongs to the middle class and has limited performance. At the same time, the technique remains quite economical.
Among the main design features of this walk-behind tractor, the following can be noted
- Transmission . This assembly combines the gearbox and clutch. The technique has 3 speeds, which are switched using a handle on the steering wheel. It can reach speeds of up to 12 km / h and carry up to half a ton of cargo.
- Frame . Consists of two elbows, which are used for mounting and fixing the motor with the gearbox. There is also an attachment for attachments at the rear.
- Motor . It is located on the frame and is the best of all the options offered. The engine life of the unit declared by the manufacturer is 5,000 hours, but with proper operation and timely maintenance, it can last longer. A special feature is the tilting piston, which is located in a cast iron sleeve, and the camshaft is located at the top of the engine and is mounted on bearings. Due to this, it is possible to provide a small mass of the motor with a fairly decent power (9 horsepower). The unit is cooled by air, which is sufficient for operation even in hot conditions. To ensure easy starting of the engine, the ignition switch is being modernized, but the walk-behind tractor is supplied with a mechanical compressor as standard, so that the engine can be started with a starter even at sub-zero temperatures.
- Clutch mechanism . It consists of a belt as well as a tensioner and a spring.
- Wheels pneumatic , can work independently of each other, as they are driven by separate mechanisms.
- There is also a depth gauge which is installed at the rear of the frame. It can be used to adjust the depth of entry of the plow into the ground.
Thanks to all these features, the walk-behind tractor is quite easy to use and maneuverable. There is a special protection on the body that protects the operator from the ingress of earth or moisture from the wheels.
Attachments
The walk-behind tractor is capable of performing similar functions as units with stronger engines. It can be used for various agricultural activities, depending on the type of installed attachments. For this, the frame has all the fixtures and seals.
The following attachments can be installed on the unit:
- hiller;
- plow;
- device for collecting and planting potatoes;
- cutters;
- pump and stuff.
Running in
Before using the unit, it is necessary to run it in, which is an important measure for its reliable operation for a long time. It is carried out in several stages and takes a total of 20 hours. This event must be carried out in order for all units and parts to rub in in a gentle mode of operation of the mechanisms. It is important to remember that the running-in must be carried out at a minimum load on the unit, which should be on average 50% of the maximum allowable load.
In addition, after running-in, the oil and filters must be changed.
Advantages
Due to all the above characteristics and features of the device, it is in demand among the population. But at the same time it has other advantages, among which the following can be noted:
- reliability;
- durability;
- low noise level;
- affordable price;
- ease of use.
It must also be said that the user, if necessary, can reduce the turning radius when one of the wheels is locked. Various operations can be carried out in wet soil with the help of attachments.
Assembly
In practice, it is noted that the walk-behind tractor is sold assembled, but after purchase, the owner may face the issue of adjusting components and assemblies. This makes it possible to prepare the machine for work, using all its characteristics to the maximum, depending on the operating conditions. The main point in carrying out such activities is the adjustment of the engine and the fuel supply system.
The pressure of the gasoline entering the engine through the carburetor is adjusted using the language tool , which is squeezed out or pressed in depending on the amount of fuel entering the carburetor. Lack of fuel can be determined by the way white smoke comes out of the exhaust pipe. Excessive amount of fuel in the combustion chamber is the reason that the engine "sneezes" during operation or does not start at all. Fuel Trim allows you to tune the normal operation of the unit depending on your needs in conjunction with the engine power. For more serious repairs, it may be necessary to assemble and disassemble the carburetor, cleaning the jets and channels inside.
In order for the engine to run smoothly, the valve system must be adjusted on it. To do this, complete with the unit there is an instruction for carrying out work, as well as the correctness and sequence of their implementation.
Before starting operation, it is necessary to clean all the elements, tighten the bolts and assemblies.
Exploitation
If you follow the steps below, the unit will run smoothly and for a long time. Among them, the main ones are:
- when installing attachments, the knives should be directed in the direction of travel;
- if the wheels are slipping, it is necessary to make the device heavier;
- it is recommended to fill only clean fuel;
- in cold conditions, when starting the engine, it is necessary to close the valve for the intake of air into the carburetor;
- periodically it is recommended to clean the fuel, oil and air filters.
Repair
This device, like any other units, may fail during operation, periodically requiring repair. It should be noted that some units cannot be repaired, but must be completely replaced. To make repairs on your own, you need to have some skills, which will quickly eliminate the breakdown. Most often, it is the gearbox that fails. In this case, the following points will appear:
- jerky movement;
- oil leakage.
And other troubles may also arise, for example, there is no spark on the spark plug or the piston rings are coked. All faults must be eliminated as quickly as possible or as soon as possible, depending on their severity. Something can be repaired by yourself.
If you do not have the skills in some complex technical problem, then it is recommended to contact a service station or to private specialists who are engaged in the repair of such machines.
Now there are many service centers that provide their services at an affordable cost
The average fuel consumption for this unit is 1.7 liters per hour of operation, and the tank capacity is 3.6 liters. This is enough to work continuously for 2-3 hours before refueling. The average cost of a walk-behind tractor may vary depending on the place of sale, the availability and type of attachments, as well as other points. On average, you need to count on a price of 10 to 15 thousand rubles.
Knowing all the advantages and disadvantages of this walk-behind tractor, everyone can make the right choice when buying. To protect yourself and purchase a really high-quality car, it is recommended to choose an original production unit with a quality certificate and all the necessary documents.
