Motoblocks are supplied to the modern domestic market by many well-known companies in the post-Soviet space. Some of these manufacturers make lightweight equipment of this type, designed to handle only small garden plots. Other companies produce professional plowmen. Among the latter is the company Ufa-Mechanika LLC. This manufacturer supplies the market with powerful, high-quality Agro walk-behind tractors. Feedback from farmers about this brand of equipment has been simply excellent.
Agro walk-behind tractor pros and cons
I would like to purchase an Agro motoblock, anyone who has something to share about this block, write.
Excellent equipment I have been using for 2 years and am quite happy with it. Only I don’t have aggro, but MTZ, but there’s practically no difference. I bought a plow, but it would be better not to buy it because I had to completely redo it, this year I plowed about 75 acres per season, made a cart, just a hiller, a digger. All that remains is to make the mower and the cutter. For me, this is the best domestic walk-behind tractor.
To be honest, the fuel consumption confuses me, it says 2 liters per hour and the tank is only 6 liters, but in reality, how are things going with the consumption?
At MTZ I have an imported Honda engine with 9 horses, so I think the consumption is normal. I didn’t find the consumption in the engine book, but based on experience, a liter is enough for 5-7 acres. It depends on the land, and our soil is not sand.
Consumption is 2 liters per hour at maximum load, otherwise less.
Hello! I have an “agro” walk-behind tractor manufactured by UMPO. I can’t say for sure the gas consumption, but at full load the tank is definitely enough for a couple of hours. When clearing snow with an auger in the yard, it takes me about an hour or so. So, the gas station is enough to clean it twice. And The 6 liter tank does not fit. One minus is that the cutter loosens finely - 8 centimeters. If you repeat the pass, you can bring it up to 12. Therefore, first I plow with a tractor (I hire it) and then go through it with a walk-behind tractor. The previous walk-behind tractor of the same production "Ural" could bury itself up to 20 cm. The walk-behind tractor weighs 160 kg. It’s difficult to transport without a hitch - the engine is not on the axis and pulls away. The attached hitch balances. The segmental mower is 110 cm. It mows well (two blades) and there are no dangers of hitting bumps. But you need a person nearby to rake the hay from the drive. They praise the rotary mower - I didn’t try to lie I won't. The trailer is from the old Ural vehicle. It pulls perfectly, and with lugs it can handle arable land. The great thing is that there is a differential with a lock, which makes it much easier to control. I haven’t tried plowing with a plow. I plant potatoes with hillers (from the Ural) and hill them up. True. There’s a bit of a mismatch in height and it’s a bit difficult when turning, but you can manage it. The medium-sized tractor harrow ZBSS-1 does not drag across arable land - it slips. But it easily drags 2 regional harrows (beet harrows). The entire hitch works from the PTO, which is also excellent - there is no hassle with belts. Gripping cutter and auger rotor -80 cm.
You have the right to think about me as you see fit. I have the right not to correspond to your ideas. God forbid from friends who do good, but I myself will not allow my enemies to survive.
Technical characteristics of the Agro walk-behind tractor
As you know, on the agricultural machinery market you can find models from different manufacturers: Chinese, Russian, European. The Agro walk-behind tractor has been produced in Russia for many years, and during this time it has proven itself exclusively on the positive side.
Important Review of semi-professional chainsaw Husqvarna 240
The units perform well not only in working in small areas, but also in processing virgin soil. The power is 8 horsepower, but by upgrading the model and installing another engine, this figure can be significantly increased.
High reliability and durability, ease of operation, endurance - all this is about this device. There is a large selection of different attachments on sale, which will significantly expand the capabilities of the machine.
She weighs 160 kilograms, and that's a plus. After all, the grip on the ground will be very good, especially if you work on heavy soils, such as clayey ones. On the other hand, transportation will be difficult precisely because of the large mass and significant size.
Fuel consumption is 6 liters per hour at maximum loads. On average, equipment will consume about two liters per hour.
The engine has the following characteristics: a four-stroke single-cylinder carburetor engine running on gasoline. It has a forced air cooling system, which allows it to work even in summer without overheating. The low compression level allows you to refuel different types of fuel: from A-76 to AI-95. The manufacturer also worked on the lubrication system. Now the liquid does not scatter in different directions, and after it is filtered, it is supplied by a pump to the elements that rub.
If you read reviews about the Agro walk-behind tractor, you will mostly see positive messages. The unit has the following advantages:
- The equipment is universal in its characteristics, so it is perfect for both vegetable gardens and small farms;
- Very simple controls. You won't have to put any effort into managing it. The motor is so powerful that it moves the equipment itself in the desired direction, and you only have to adjust the path;
- The model is professional, so it copes well with cultivating large areas of land, as well as transporting huge loads;
- Wide bore of attachments. Moreover, the model works great even with homemade tools. Therefore, if you are missing something, you can always do it yourself.
There is also something that causes some difficulties for users. So, the carburetor does not work very well. The car itself is designed for heavy loads, but the carburetor does not agree with this, and you may encounter “floating” speeds.
There are also problems with the fuel tank, which has a flat bottom. It is relatively small in size, but sometimes problems occur with the supply of gasoline to the engine.
Common breakdowns:
- Problems in the gearbox chain;
- Complete waste of lubricant in the ratchet;
- The engine cylinder head gasket wears out;
- The fuel tap becomes clogged;
- Spark plug broken.
If you experience any strange operating problems, immediately turn off the engine and let it cool. After this, open the repair instructions, study it carefully and you can safely begin to search for the problem and how to fix it. In fact, repairing an Agro walk-behind tractor is not as complicated as it might seem at first glance. Even those who have no skills, but have the desire to do everything with their own hands, can handle it.
Motoblock Agro (Agros) - reviews, comments and suggestions
Hello everyone. I would like this topic to be related to the problems, improvements and alterations of MB Agro. Also present on the forum is Alex 02, who works in Bootes, and will be able to give qualified answers to problems that arose during operation or any breakdowns. There was also a conversation about the possibility of sending spare parts for equipment produced by the Ufa plant. Request to Alex 02 in this topic to post catalogs of spare parts for all equipment (which are available). I hope in this topic all the problems of Agrovodov will be completely resolved.

A simple homemade potato digger for the Agros walk-behind tractor
The potato digger's ploughshare is made from a sawmill. On top of the ploughshare there is a wedge with the shape of a hiller, which consists of two halves and is welded to a curved pipe. Two rows of pins are welded to the wedge and plowshare.
The role of the field board is performed by a vertical stand, which gives rigidity to the unit. A rod with a screw end is connected to the bottom of the drawbar, onto which the axle of the wheelset, a hook for coupling and a mechanism that regulates the plowing depth are attached.
Motoblock Agro: video, reviews
Auto mechanic, specializes in agricultural equipment
The manufacturer of walk-behind tractors Agro produces heavy professional-class units. Despite the high fuel consumption and heavy weight, this equipment is durable and multifunctional. The units do not have high maneuverability, but they can be easily converted into a mini-tractor. Another advantage of the car is that it is equipped with large wheels with treads. Motoblocks from the manufacturer Agro are especially popular in Russia because they have high performance and reliability.
Farmers' suggestions for improvement
At the moment, “Agro” is practically the only professional heavy walk-behind tractor produced in Russia. Judging by the reviews from farmers, this technology is quite good. However, in the design of such walk-behind tractors, according to the owners of household plots, there are still certain “jambs”.
For example, some farmers would advise the manufacturer to make gear shifting clearer in these walk-behind tractors. Also, as the owners of land plots note, in order to replace the oil seals, Agro has to disassemble almost the entire engine. In addition, many farmers believe that it would be nice for these models to have stronger steering.
The weight of Agro walk-behind tractors is, of course, heavy. But many plot owners advise the manufacturer to also start producing models for 200 kg. Owners of small farms would, of course, really like such plowmen. For arable land, the Agro plow, judging by the reviews, sometimes, unfortunately, is a little lacking in weight.
Design Features
Agro motor cultivators are designed to perform various agricultural work, such as cultivation, hilling, cleaning the territory, plowing, mowing, and transporting construction materials.
In this video you will learn more about the Agro walk-behind tractor:
The design of the machine is based on a single-axle design with a power take-off shaft. The device is equipped with a durable transmission. The main components of the equipment are a locking differential, a dry clutch and a gear reducer.
Attention! The unit is equipped with a four-speed gearbox, reverse which makes it possible to rotate the equipment 360 degrees.
Another feature of the equipment is the ability to withstand various attachments for the Agro walk-behind tractor, not only branded ones, but also homemade ones. This fact provides the unit with versatility.
How to make a rake for a walk-behind tractor with your own hands
To make a rake for a walk-behind tractor with your own hands, use water pipes. Next, you need to put a special bushing on the cylindrical rod and rotate the unit by tapping the surface. In this case, it is advisable to take a semicircular or round file.
All components are fastened by electric welding instead of bolted twisting. To facilitate transportation, the rake to the walk-behind tractor is made collapsible.
User manual
Before using the Agro walk-behind tractor, you should read the instructions for use. It describes all the nuances of maintenance and operation of equipment.
Fuel and oil
A clear advantage of the unit is its unpretentiousness in choosing fuel. For these purposes, 80, 95 and 92 gasoline are used. The main thing is that the fuel is clean, without any impurities. Otherwise, the system may become clogged. The main nuance of the design is that the fuel tap is located at a height of 1.5 centimeters from the bottom of the tank, and if the gasoline in the tank is less than this mark, it will not flow into the carburetor.
In the description of the instructions for the Agro walk-behind tractor, it is recommended to use M-BZ/12G1 oil in the summer, and M-5Z/10G1 oil in the winter. If you don’t want to worry about changing the oil seasonally, then use a 15W-30 or 10W-30 series fluid. The lubricant should be changed every hundred hours of operation.
Run-in
This process should be given special attention, since the life of the machine depends on it. Before using the walk-behind tractor for the first time, you should fill it with oil and gasoline. Next, let the device run for some time at medium power. It is better to use an empty cart for this.
Minitractor from the Agro walk-behind tractor
The Agro or Agros walk-behind tractor is very popular among farmers. The reason for this is its high-quality assembly, durability, and functionality. Agro and Agros are two names for one model.
This walk-behind tractor is a development of a plant in Ufa - Ufa MPO. “Agros” have been produced in Ufa since 1998, soon after the start of production the model was called “Agro”, but among farmers it is known by both names.
Which model to take as a basis?
The power of "Agro" is 8 hp. or 5.8 kW, has gained great popularity for many reasons, the main one of which is the build quality, Russian production, as well as the high quality of the parts from which the walk-behind tractor and high power are made.
The walk-behind tractor is equipped with a UMZ-341 carburetor engine (4 strokes, 1 cylinder, fueled with gasoline). In terms of characteristics and operating parameters, the engine is similar to the Honda GX240.
Due to its high power and good traction performance, the Agro walk-behind tractor is a popular base for conversion into a mini tractor. Since the manufacturer has only one model in the Agro model range, it is used as the basis for creating a mini tractor. The weight of the walk-behind tractor is 160 kg.
Farmers who have independently converted a walk-behind tractor into a mini tractor also recommend using weights with an average weight of up to 40 kg.
We bring to your attention a video about the Agro walk-behind tractor, converted into a homemade mini tractor:
What is required to create a mini tractor from a walk-behind tractor?
To make a mini tractor with your own hands, you will need not only the Agro walk-behind tractor, but also a certain set of additional components, namely:
- welding machine;
- wheels (you can use wheels from VAZ 2106);
- operator's seat or car seat;
- steering wheel;
- steel profiles, steel sheets;
- fasteners (bolts, nuts, angles);
- grinder with discs “for metal”;
- electric drill;
- hammer and other tools;
- bearings, bushings;
- metal pipes of the required diameter;
- hubs with brakes.

Possible causes of breakdowns
- Wear of parts. To avoid this problem, it is necessary to inspect the unit before each start of work.
- Jerking while performing work. In this case, you need to check the tire pressure and adjust the hitch correctly.
- Strong vibrations. To do this, tighten the bolts.
- Difficulty starting the engine. You can solve the problem as follows: check the condition of the oil and parts, tighten the bolts.
- Problems after winter downtime. In this case, the wires quite often oxidize and debris accumulates in the carburetor. To prevent the situation, you should check all parts before use and only then start work.

It is from such consumers that these walk-behind tractors have earned the best reviews. Most often, Agro models are used by farmers and summer residents for:
- plowing the land;
- harrowing and cultivation;
- cutting beds;
- mowing;
- hilling and harvesting potatoes.
That is, such equipment is intended primarily for performing agricultural work.
Owner reviews
Andrey, 46 years old, Ufa
“I bought the Agro walk-behind tractor not new. I read a lot of reviews about modifications for a mini-tractor, I really liked the proposal. I put it on a frame from the Urals, but I would like to share a note for the owners, do not forget to disable the wheel lock, as happened with me. I drove it all summer, and then the wheels stopped turning, and repairs were much more expensive.”
Kirill, 27 years old, Volkhov
“I purchased an Agros unit, I don’t use it very often, since I have another walk-behind tractor. I use agro more for transporting goods. Among the advantages of the machine, I can highlight good speed in fourth gear and high power when clearing snow. There are also disadvantages - almost every car breaks down the final drive axle shaft. A friend encountered the same problem and changed it himself. I’m doing great so far.”
Vadim, 35 years old, Irkutsk
“I’ve been using my Agros for almost eleven years. I was never disappointed in the purchase. I am very pleased with the engine, it is much better in terms of design than its imported counterparts. However, there is also a minus - the cutter is not intended for agricultural work on heavy soils and at great depths. Otherwise, I didn’t see any shortcomings, so I can confidently recommend this walk-behind tractor to everyone I know.”
Agro walk-behind tractors are durable and high-quality equipment for professionals. They are easy to operate and repair, differ from other units in power and reliability.
Motoblock Agro
Agro is a family of heavy professional-class walk-behind tractors. Despite its slowness and gluttony, the equipment is distinguished by a high margin of safety and has outstanding capabilities. Possible operational problems can only be associated with maneuverability, since the walk-behind tractor is very heavy and can be compared with full-fledged mini-tractors. In addition, the equipment is equipped with large “toothed” wheels. High reliability and performance have allowed the Agro walk-behind tractor to become one of the most popular in the world.
Comments from summer residents
Judging by the reviews of owners of land plots, there are therefore many advantages to walk-behind tractors of this brand. But of course, this technique also has some disadvantages. These farmers primarily include:
- inconvenience in preparing for haymaking;
- fairly rapid failure of the ignition coil;
- no counterweights included.
Also, some farmers consider the disadvantages of these walk-behind tractors to be that they do not start very well in the cold. Strong noise and vibration, of course, can also be attributed to the disadvantages of Agro.
Attachments
The walk-behind tractor of the same name is rarely purchased in the basic configuration. After all, in order to appreciate the huge range of Agro’s capabilities, it is necessary to use it with various auxiliary models. Of these, we note only the most common elements recommended by the manufacturer:
- Mounted unit ANM-4
- Mower (segmental) KN-1
- Mower (regular) – KM 0.5
- grouser
- Hiller
- Snow removal product SM-2B
- Potato digger
- Potato planter
- Cart PTM-500
- Milling cutter (several pieces)
- Brush ShchP-09
- Blade The basic package includes only pneumatic wheels and a universal hitch that allows you to connect attachments from third-party brands.
Characteristics and engine
Agro equipment has the following characteristics: body length - 1800 mm, width and height - 850 and 1100 mm, respectively. Ground clearance is 250 mm, and the minimum turning radius reaches 1200 mm.
The walk-behind tractor has a non-adjustable track - its width is 600 mm. The weight of the entire structure is 160 kg.
Naturally, with such dimensions and weight, the equipment is very difficult to transport. There are many disadvantages, but there are many more advantages. In this case, the main thing is to have a specific idea of where the walk-behind tractor will be used.
The walk-behind tractor is designed for a processing depth of up to 200 mm, and the traction force is 100 kgf.
The maximum weight of transported cargo (with a trailer) is 500 kg. Agro is capable of moving at speeds of up to 15 km/h.
The UMZ-341 1-cylinder petrol carburetor, equipped with air cooling, is responsible for performance. In fact, this engine is a copy of the Japanese Honda GX240. There is support for fuel ranging from A-76 to AI-92. The large tank provides an acceptable range until the next refueling.
With a displacement of 0.3 liters, the power plant develops 8 horsepower and torque is 17 N/m. The engine uses one cylinder with a diameter of 79 mm.
The engine is already initially adapted for use in difficult conditions. In the restyled versions, the developers managed to improve the lubrication system. So, if previously lubrication was carried out by splashing, now the oil is supplied under pressure using a pump. In this way, especially rubbing parts are lubricated. Before entering the rubbing elements, the oil is filtered in a replaceable filter.
Engine UMZ - 341 for the Agro walk-behind tractor - technical specifications, instructions, malfunctions
In 1999, OJSC Ufa Engine-Building Production Association began manufacturing a new generation carburetor engine, UMZ-341, developed by factory specialists.
