Carburetor for agro walk-behind tractor

Prices in Russia

The average cost of a new Agros / Agro walk-behind tractor is between 50-60 thousand rubles. This is how much the basic equipment costs, while the versions with attachments are much more expensive. Attached options increase the price by an average of 10 thousand rubles.

Since the walk-behind tractor has been produced for more than a dozen years, it can be found on the supported market in huge quantities. You should beware of copies in poor condition, of which there are many. Experience shows that a walk-behind tractor in good condition will cost about 30-40 thousand rubles, together with mounted options.

Motoblock Agros successfully competes with the Belarus-09N and Burlak 10 DF models.

Design

The design of the walk-behind tractor is simple, it is not difficult to repair the unit in the field, you can always find the necessary spare parts on the market at a reasonable price. Agro characteristics:

• body length 1182 mm;
• height 855 mm and 1110 mm;
• ground clearance 252 mm;
• turning radius 1210 mm;
• unregulated track width 610 mm;
• the structure weighs 162 kg.

This unit has its drawbacks, but there are much more obvious advantages. The walk-behind tractor is planned for a processing depth of up to 205 mm, while the traction impulse can reach 100 kgf. A walk-behind tractor can transport half a ton of cargo at a speed of 15.2 km / h. The engine is equipped with a UMZ-341 carburetor, which runs on low-octane gasoline. The motor has a "progenitor" - the Honda GX240 engine. The power plant is also capable of operating on 92 gasoline.

The engine has:

• volume 0.3 liters;
• power 8 horsepower;
• torque 17 N / m;
• there is only one cylinder in the engine, its diameter is 79 millimeters.

Fuel is consumed on average two liters per hour, its actual consumption is 395 (289) g / kWh. The oil is supplied under pressure using a pump, passing through a filter, it is well cleaned.

Additional dimensions:

• track 610 mm (changes are possible up to 755 mm);
• turning radius 655 mm;
• the skeleton of the frame does not have, instead of it there is a transmission case;
• parameters of wheels 6x12 inches;
• the pressure in the wheels is 0.09 -14 MPa.

The starter for the walk-behind tractor is the most important element, without it the engine cannot work normally. The part often fails, it is not difficult to change it. Also in the power plant there is a backup starter - an electric starter (on the latest models there are two of them). You can also start the engine manually

It is important to note that the amount of battery capacity affects the duration of the starter

If a strange grinding sound is heard in the gearbox, then this is a signal that it is necessary to add oil to the gearbox. It also happens that the oil is of poor quality. Therefore, it is best to use a lubricant recommended by the operating instructions. If in the process of using the walk-behind tractor there are complaints about the gearbox, then it should be disassembled and the gear teeth straightened. It often happens that the teeth should be changed. In order to correctly adjust the axial arrangement of the shafts, additional locking rings should be installed. Also, bearings often wear out, they should also be replaced.

The unit has a 6.2-liter fuel tank, the engine consumes about three liters per hour of operation. Much depends on the volume of work of the valves and the load on the engine, the consumption can reach four liters. On the market, walk-behind tractors are sold on average from 25 to 30 thousand rubles, there is always a steady demand for such equipment. A non-new unit with a complete set will cost at least 46 thousand rubles. If the technique is "zero", that is, completely new, then the price can go up to 65 thousand rubles.

Agro's analogues with which it successfully competes:

• "Belarus-09H";
• Burlak 10 DF;
• "Belarus 08 MT".

The lineup

Motoblocks "Agro" are created at the specialized enterprise "Ufa Engine-Building Production Association". The history of the plant dates back to the creation of aircraft engines.More than twenty years ago, the management of the enterprise developed a model, which began mass production in 1998. Agrarians welcomed the appearance of a new unit; it began to enjoy massive demand among rural workers.

Unit characteristics:

• excellent build quality;
• low price;
• guarantee;
• service maintenance;
• there is an UMZ-341 engine;
• single-cylinder four-stroke design (8 HP).

How to adjust the carburetor on an agro walk-behind tractor

In order to configure the equipment, you need to understand what is being done in this case. For example, additional adjustment can be done without removing the device; with full adjustment, you will need to remove the technical element. Let's take a closer look at the process of setting options:

1. first of all, it will be necessary to dismantle this device from the corresponding place of equipment;
2. the next step will be a complete rinsing of the structural element in a gasoline solution;
3. then you have to completely clean the neck using a lint-free rag, and in addition, moving the flap to the side;
4. the next step is to completely dry the device, after which the required gap is set using the adjusting mechanisms.
   This is interesting: adjusting the carburetor of the walk-behind tractor.

At the final stage, the device is mounted in place, after which the motor-cultivator is started. Here, it will be necessary, through the same adjusting elements, to bring the position of the damper to the optimal level so that the mixture is supplied smoothly, while the engine has normal rpm and smooth operation.

X45p

In this case, we are talking about a fairly high-quality analogue of the Japanese version of the fuel supply to the engine. This fixture is configured in the same order, but here the need for periodic adjustments should be highlighted, since such versions may fail due to the lower build quality and materials used. These indicators are partially affected, but at the same time, a rather low cost is allocated in comparison with the original Japanese spare part.

Possible causes of breakdowns

1. Wear of parts. To avoid this problem, it is necessary to inspect the unit before each start of work.
2. Jerks during the execution of work. In this case, you need to check the tire pressure and adjust the linkage correctly.
3. Strong vibrations. To do this, tighten the bolts.
4. Difficulty starting the engine. You can solve the problem as follows: check the condition of the oil and parts, tighten the bolts.
5. Malfunctions after winter inactivity. In this case, the wires are often oxidized, and debris accumulates in the carburetor. To prevent the situation, you should check all the details before use and only then start work.

The main characteristics of the Agro walk-behind tractor

The walk-behind tractor has the following characteristics:

• can carry out any agricultural work in small, medium and large areas;
• will be useful for gardeners;
• used for communal functions (cleaning, transportation, cleaning);

• availability of attachments, the ability to adapt to work with attachments from the "Ugra", "Neva", "Kaskad", "Salyut", "Oka" motor-blocks and other Russian motor vehicles;
• engine reliability, good performance reviews, endurance and durability.

Attachments

Complete with trailed and attached equipment for the Agros walk-behind tractor using a hitch, the unit is capable of performing a wide range of agricultural operations, including:

• plowing the site;
• loosening, leveling the soil;
• reclamation;
• chopping and removing weeds;
• hilling of industrial crops;
• harrowing;
• digging up root crops;
• planting seeds of grain and vegetable crops in the ground;
• mowing vegetation and shrubs;
• landscape work;
• snow removal work;
• transportation of goods.

The module is also used in housing and communal services.

Motoblocks can be used with attachments, these are:

• plow NP-1;
• rotary tillers - 20.00.000;
• diggers;
• harrow cultivator;
• potato planters;
• lugs;
• front mowers KN-1, KN-1.5, KN-02;
• 2-row hiller CTB;
• snow blower SMB-2;
• cart trailer PTM-500.

Each mechanism performs its own operation. The potato digger for the Agros walk-behind tractor digs up root crops. The harrow cuts off the top layers of the soil without turning the soil. A trolley with a load of no more than 400 kg is a single-axle, dump trailer with a body tilting back 30 ° and is used for transporting crops, implements, household items.

The design features of Agros are that it has a universal hitch, with which it is allowed to attach additional equipment from other manufacturers and homemade hinged mechanisms.

Front adapter

The front adapter is a special module attached to the walk-behind tractor and consisting of the following parts:

• driver's seat;
• frame for the installation of structural parts;
• wheel axle or axle with 2 wheels;
• a hitch for attaching a walk-behind tractor and adapters for attachments;
• steering wheel.

In terms of functionality, such a machine is similar to a mini-tractor, in which the driver takes a comfortable position and skillfully controls the mechanism. The front adapter is easily assembled with a walk-behind tractor and is aggregated with any attachments.

The manufacturer does not produce a device for the Agro walk-behind tractor, but the universal hitch allows you to install adapters from other manufacturers. Some motorcycle owners make an adapter for a walk-behind tractor with their own hands.

Rotary mower

The rotary mower KM-0.5 is designed for the Agro machine. It consists of 2 self-sharpening knives located on the bottom surface. The height of the knives is 0.5-10 cm. The mower mows grass vegetation and small bushes.

Unstable turnover

The main complaint of the owners about the operation of the device is the instability of the engine speed, as a result of which it begins to sneeze.

The cause of the malfunction may be the establishment of a large gap in the gearbox cover, which should be readjusted to values ​​from 0.2 to 0.5 millimeters. In this case, the power may drop, which is a consequence of contamination of the carburetor, fuel pump hose or air intake filter, as well as crankcase breakage and the formation of carbon deposits in the fuel combustion chamber. You just need to inspect and clean all the components.

General information, purpose and design features

To begin with, it should be noted that "Agros" and "Agro" are absolutely identical walk-behind tractors. Agros is an earlier version, and the design of the model has not changed much over the years of production.

The car is produced at the Ufa Engine-Building Plant, which was founded in 1925. In the 1920s and 1930s, the enterprise was considered the largest aircraft engine manufacturer in the USSR. In peacetime, the plant began to master the production of agricultural machinery. The working staff of the enterprise now consists of more than 200 people. As for the Agros walk-behind tractor itself, its release was mastered in 1998. The project turned out to be so successful that over the past years, about 40 thousand motor-blocks of the same name, as well as various attachment options for them, have been produced and sold.

The release of the walk-behind tractor of the same name was completed in 2008 due to a complete halt in the production of all such equipment at the Ufa plant. The fact is that the company began to receive more orders for the production of aviation equipment, which is more profitable. In this regard, the assembly of "Agros" was discontinued. However, later the walk-behind tractor began to be produced at another plant, which belongs to the Chamber of Commerce and Industry of Ufa-Mechanics LLC.

The Argos model allows you to efficiently and efficiently carry out work on soil cultivation, planting and digging up root crops and other vegetable crops. The rich basic equipment allows you to perform the required amount of work for the first time. Thanks to the ability to connect various attachments, the walk-behind tractor can be turned into a full-fledged mini-tractor capable of working the soil to great depths, pumping water, transporting goods, etc.

Agros has a uniaxial design with a power take-off shaft. The equipment is equipped with a differential with manual locking

This device is responsible for the distribution of the load on both wheels, which is very important when driving in difficult terrain.

It can be noted without any doubt that the Agros walk-behind tractor, together with the mounted options, has more capabilities. That is why, when choosing this technique, many are looking at buying additional options that allow 100% to unleash the potential of the walk-behind tractor.

Care features

Like any technical device, the Agro walk-behind tractor requires maintenance, so you should have a good idea of ​​how best to carry out repairs. Reasons for breakdowns of the Agro unit:

• wear of parts;
• improper operation;
• disregard of safety rules.

The most common faults are:

• spark plugs do not work;
• engine oil is produced;
• gaskets wear out;
• the fuel wire is clogged;
• the chain breaks.

If you look more closely, you can draw the following conclusions. The transmission units are heating up, the reason is the heating of the bearings due to a lack of oil in them, it is also possible that the oil is substandard. To repair this unit, you must first disassemble, change the bearings, as well as the oil itself. Then you should adjust all the nodes and assemble all the elements.The most common breakdown is a disruption in the operation of the transmission; for this, the clutch should be debugged on time and correctly. If the clutch is too tight, then the screw must be unscrewed slightly. If slippage is observed, then the screw is tightened in this case. Sometimes the clutch needs to be disassembled. This is done in the following sequence:

• old oil is drained;
• the transmission is disconnected from the engine;
• the spring is removed from the pressure plate;
• disks are dismantled;
• the lock washer is removed;
• remove the nut that secures the drum;
• after elimination of defects, the assembly is carried out in the reverse order.

During operation, there are sometimes sudden jerks of the unit. This indicates insufficient tire pressure. Another reason is attachments that need to be tidied up and adjusted. Maintenance of the power plant is reduced in 85% of cases to the replacement of parts that have served their life. These include the large spring and the second starter. The electric starter is directly connected to the battery, testing and installation is done according to the instructions.

In order for the walk-behind tractor to work for many years without complaints, an average check of the unit should be done once every three months. The power plant has a belt connection. If the belt is too tight, it can be damaged. If the belt is too loosely tensioned, then "slippage" will be observed, the engine will not give out the required revolutions. A routine inspection of the belt is mandatory.
