What engine can be installed on an agro walk-behind tractor?

Breakdowns and repairs

The Agro unit differs from other heavy-duty models in its long service life and reliable operation.
The operation of the walk-behind tractor is influenced by operating conditions, proper running-in after purchasing the factory unit, and timely maintenance and care.

If the unit is under warranty, then all repair work must be carried out by the module manufacturer. The owner has no right to open the seals and repair it. If the malfunctions of the walk-behind tractor are minor, then you can adjust its operation yourself.

Possible breakdowns and damage are presented in the repair instructions for the Agros walk-behind tractor and have a general appearance. Among them are the following:

problems with starting and engine malfunctions;
The chassis does not work;
malfunctions in the gearbox (gearbox);
clutch failures;
the lubrication and cooling system is broken.

If the engine does not start, the reasons and solutions are as follows:

There is no fuel in the fuel tank. Fill the tank with fuel.
The hole in the gas tank cap is clogged. Open the tank cap, clean the hole and reinstall.
Fuel is leaking from the carburetor. It is necessary to adjust the carburetor of the walk-behind tractor.
Fuel system clogged. Drain the fuel from the fuel tank, rinse with gasoline and blow out the carburetor jets, inspect the spark plug.
Filter clogged. Replace or clean the filter.

If the engine operates with noise, knocking or jerking, it is necessary to adjust the valves on the Agro walk-behind tractor using special probes.

If the idle speed is unstable, the gap in the gearbox cover may be too large, so it is necessary to adjust the gap to 0.2-0.5 mm.

A decrease in the power of the walk-behind tractor is possible in the following cases:

clogging of the carburetor, gas hose, air filter;
crankcase cuff failure;
carbon deposits in the combustion chamber.

Elimination methods include inspection, cleaning all parts, and blowing off the hose.

If the starter of the Agro walk-behind tractor fails or the fuse blows, the best solution is to replace unsuitable parts.

Malfunctions of the gearbox chain appear as a result of its jamming. The clutch can be damaged if the chain breaks, so it needs to be replaced.

The following failures and breakdowns are possible in the gearbox:

the kinematics inside the gearbox are disrupted;
spontaneous gear changes or their complete absence;
oil leak on the shift shaft.

It is better to repair the box in special workshops. A gearbox is a complex unit, and you can’t do it without knowledge of mechanics.

Ignition system

In the “why there is no spark” problem, the reasons for the breakdown lie in the details, such as:

candle;
magneto;
cap;
high voltage wire.

If there is no spark or sparks weakly, it is necessary to adjust the intermediate gap and check the condition of the electrodes. The gap norm is 0.8 mm.

When there are changes in the gap between the intake and exhaust valves on the engine, they are tightened or relaxed to the permissible value.

A low compression ratio has been detected in the cylinder. All worn parts are removed and replaced.

Cleaning the muffler will also help get rid of the spark problem.

Engine replacement

If the engine for an Agro walk-behind tractor breaks down and needs to be replaced, use an adapter kit. Instead of a native motor, imported ones with a cylindrical shaft with a diameter of 25 mm are suitable:

Weima - with a power of 13 hp. With.;
Subaru EX 27 - 9 l. With.;
Honda 9 - 13 l. With.;
Lifan 9 - 13 l. With.

Replacing the engine is as follows:

remove the motor from the cultivator and dismantle the clutch mechanism;
remove the drive cup under the conical shaft and replace it with one machined under the cylindrical one;
A walk-behind tractor clutch is installed on the imported engine and connected to the transmission.

Spare parts

With constant use of the machine, spare parts may wear out. Most often, parts of the clutch mechanism and bearings need to be replaced. There are no problems with choosing parts for Agro. They can be purchased both from official dealers of the company and in the open market.

Malfunctions and their elimination

Long-term operation of the part directly depends on proper operation and running-in of the new motor, as well as on timely maintenance and proper care. But any equipment is subject to wear and tear. Let's look at the main operational problems:

Unstable startup and malfunctions.
Malfunctions in the chassis.
Problems in the functioning of the gearbox. Oil may leak, change speed on its own, or, conversely, not turn on. It is better to contact knowledgeable specialists and not engage in independent repair of this complex unit in the unit.
The clutch is not working properly.
Violation in the lubrication and cooling system.
The engine does not start. Let's look in more detail at the causes and solutions.
No fuel. Just refuel the unit.
The hole in the neck of the gas tank is clogged. Open the lid, clean it and put it back in place.

To troubleshoot problems, contact a technician for help.

Gasoline is leaking from the carburetor. Adjust the injection system.
The filter is clogged. It should be cleaned or replaced.
The engine is noisy, knocks and operates jerkily. You need to adjust the valves using a feeler gauge.
The starter starts unstably. In this case, it is better to replace the failed parts.
The speaker circuit is faulty. This happens when a part jams. To avoid further damage to the clutch, it is better to replace it in time.

General information, purpose and design features

For starters, it’s about and “Agro” - absolutely identical walk-behind tractors. Agros is an earlier version, and the design of the model has remained almost unchanged over many years of production.

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

The production of the walk-behind tractor of the same name was completed in 2008 due to a complete stop 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 stopped. However, later the walk-behind tractor began to be produced at another plant, which belongs to the Chamber of Commerce and Industry of Ufa-Mechanika LLC.

The Argos model allows you to efficiently and effectively carry out work on cultivating the soil, 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 cultivating the soil to great depths, pumping water, transporting loads, etc.

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

This device is responsible for distributing the load on both wheels, which is very important when driving in difficult to reach areas.

It can be noted without any doubt that the Agros walk-behind tractor, together with mounted options, has wider capabilities. That is why, when choosing this equipment, many people are looking at purchasing additional options that allow them to unlock 100% of the potential of the walk-behind tractor.

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.

The engine of the Agros walk-behind tractor with a volume of 333 cm³ is similar in design features to the Japanese Honda GX240 engine, has a lower compression ratio, and is less demanding on fuel. The car is designed for gasoline from A-76 to AI-92.

The module has a reliable transmission and a 2 by 2 wheel suspension system. The wheels are mounted on final drive shafts and are equipped with pneumatic tires with a pressure of 0.08-0.12 MPa.

The Agros walk-behind tractor has a rod steering, adjustable in height and changing direction in the opposite, left or right direction at an angle of 30° to the main movement.

The manufacturer has also improved the lubrication system. Oil is supplied to the rubbing parts under pressure through a pump after filtration.

Attachments

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

plowing the site;
loosening, leveling the soil;
land 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 bushes;
landscape works;
snow removal;
transportation of goods.

The module is also used in housing and communal services.

Walk-behind tractors can be used with attachments, these are:

plow NP-1;
Rotary rotary cutter - 20.00.000;
diggers;
harrow-cultivator;
potato planters;
lugs;
frontal mowers KN-1, KN-1.5, KN-02;
2-row hiller STV;
snow blower SMB-2;
trolley-trailer PTM-500.

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

The peculiarity of the Agros design is that it has a universal hitch, with which it is possible to attach additional equipment from other manufacturers and home-made attachments.

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 installing structural parts;
wheel axle or axle with 2 wheels;
hitch for attaching a walk-behind tractor and adapters for attachments;
steering wheel.

Such a machine is similar in functionality to a mini tractor, in which the driver occupies a comfortable position and skillfully controls the mechanism. The front adapter is easily assembled with a walk-behind tractor and can be combined with any attachment.

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 owners of motor vehicles make an adapter for a walk-behind tractor with their own hands.

Rotary mower

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

Salyut 100 with 168F engine - description and price

Of the huge number of units with a Lifan engine with a power of 6.5 hp, the Salyut-100 walk-behind tractor

When equipped with a Lifan 168F engine, such a walk-behind tractor costs about 30,000 rubles. It has a relatively small weight (76 kg), which, combined with the average motor power for this class of equipment, makes it unsuitable for plowing without additional weight.

But for cultivation it is quite good due to the included sectional cutters, which allow you to change the working width from 300 to 800 mm depending on the severity of the soil.

A huge advantage of the Salyut-100 walk-behind tractor over a number of classmates is the use of a gear reducer, which is more reliable than a chain reducer. The box, which has two front and one reverse speeds, is additionally equipped with a reduction gear.

The Salyut walk-behind tractor does not have a differential, but the narrow wheel track (360 mm) coupled with its low weight does not make turning it labor-intensive.

Sectional cutters with protective discs;
Tread expander bushings;
Share;
Rear linkage bracket;
Tool set;
Spare belt.

Additionally, it can be equipped with a plow, blade, snow blower, metal wheels with developed lugs and other equipment that is widely compatible with most domestic walk-behind tractors.

Lifan 168F-2 7A

Motor variant equipped with a lighting coil capable of powering consumers up to 90 W. This allows it to be used on a variety of equipment that require lighting devices: motorized towing vehicles, light swamp vehicles, and so on. The shaft landing diameter is 20 mm.

Carburetor gx 390

Before considering how to adjust the carburetor on an Agro walk-behind tractor, you should clarify which option is installed on the walk-behind cultivator, which will allow you to analyze in more detail the process of actions that need to be performed to adjust the device. Let's consider the main points regarding this device, and also version 45 for Agro walk-behind tractors, since they are most often found when arranging a cultivator:

First of all, it should be noted that the 390, unlike the 45, is produced by Honda.
In turn, the carburetor for the Agro 45 model walk-behind tractor is made by a domestic manufacturer.
This device has a corresponding adapter for installation on a motor cultivator of this version.
The device is equipped with two separate devices for adjusting the position of the damper.
This well-known model is very popular, but has a relatively low cost (you can purchase the part for 1.5 thousand rubles in the appropriate store or online).

In this video you will learn more about the GX390 carburetor:

Description

This version is nothing special. Here, standard materials and technologies are used in production. The only thing that can be highlighted is the noticeable quality of the Japanese part in comparison with domestic analogues, or similar carburetors from other manufacturers. The device is equipped with a traditional neck, a special valve, and in addition a fuel tap for pumping in an enriched mixture. Additionally, the necessary elements for adjusting the position of the damper are displayed on the design.

Carburetor gx 390 on agro walk-behind tractor

Auto mechanic, specializes in agricultural equipment

At the moment, when processing soil, humanity uses various special-purpose equipment. There are devices of varying complexity here.

Special attention should be paid to motor cultivators, since this series of equipment is used everywhere from agriculture to personal gardening. This equipment option is not distinguished by a complex device, however, equipment owners need to understand how the carburetor and fuel supply of the Agro walk-behind tractor, as well as other common models of equipment, are adjusted in practice

Unstable speed

The main complaint of owners about the operation of the device is the instability of 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 adjusted to values from 0.2 to 0.5 millimeters. In this case, power may decrease, which is a consequence of contamination of the carburetor, fuel pump hose or air exhaust filter, as well as crankcase failure and carbon deposits in the fuel combustion chamber. You just need to inspect and clean all the components.

Operating and Maintenance Instructions

Before you start using the Agro walk-behind tractor, read the operating instructions. Keep the instructions for the entire period of use of the unit.

Oil and fuel

Recommended by the manufacturer:

engine oil - for air-cooled carburetor engines, according to the season, for example, SAE15W/30;
gearbox oil - SAE80/W90;
fuel - gasoline AI-86, 90;
lubricants - Litol-24, synthetic grease, fatty grease.

First launch and run-in

Before the first start, set the gearbox lever to neutral and the PTO to the disengaged position.

It is allowed to perform light types of transport work (with a light trailer load), as well as work with a walk-behind tractor at partial engine load.

Main causes of breakdowns

The Agro walk-behind tractor may not start for several reasons:

insufficient amount of fuel;
insufficient oil level;
hypothermia of the walk-behind tractor, too low air temperature (in winter);
more serious faults requiring repair.

The most common problems:

oil leakage (can occur due to wear of the cuffs or due to their damage, can be eliminated by replacing the cuffs);
the clutch is not completely disengaged (the clutch lever moves freely, the cable is pulled too far, this can be eliminated by replacing or shortening the cable, as well as adjusting the lever to normal);
there is no full torque (perhaps the pressure spring is weakened or the drive cup is worn out, this can be eliminated by replacement or adjustment).

This is interesting: Technical characteristics and reviews from owners of the Agromash M-20 walk-behind tractor

What do craftsmen most often encounter?

Typically, the following problems occur when working with walk-behind tractors:

The fuel sump valve is clogged. With such a malfunction, the engine starts to start, but stalls literally after a minute. In this case, it will require thorough cleaning of the sump, then rinsing with gasoline and purging.
Transmission components get very hot. The reason for this is mainly a lack of transmission oil in the crankcases or its incorrect condition, wear of the bearings. The latter will need to be replaced, the oil may just need to be topped up, only then the problem will be eliminated.
The ratchet has run out of lubricant. This problem will immediately make itself known with noisy creaking sounds made by the walk-behind tractor engine. The solution is simple - you need to re-lubricate the ratchet with machine oil.
The spark plug is faulty. Since it does not produce a spark, the engine does not start. If upon inspection you find that the contacts are badly worn and there is dry black soot on the insulation, you will most likely have to replace it.
Problems with the gear chain. The output shaft may stop rotating, and the gearbox itself will begin to jam sharply. If the chain breaks, the clutch of the Agro walk-behind tractor may be completely damaged and there will be a need to replace it. The condition of such systems should be monitored especially carefully, as they directly affect the level of efficiency of the unit.

If you are not a professional in this matter, especially serious faults should be entrusted to an experienced specialist. When carrying out repairs, it is better to use exclusively original spare parts for the Agro walk-behind tractor, which must be of high quality. However, for many models of this company, the installation of parts from some other manufacturers is also acceptable. That is, another engine can easily be installed on an Agro walk-behind tractor - for example, Lifan or Greenfield. To do this, you will only need to select a clutch adapter.

Replacing the engine on “Agro” walk-behind tractors

Since the company stopped producing new models back in 2011, but Agro walk-behind tractors still serve faithfully for many business owners, there are ways to rehabilitate the unit even after the engine itself has fallen off. In order to make a replacement by installing an imported one instead of the native one, you need a transition kit. As alternative spare parts, engines with a cylindrical shaft with a diameter of 25 mm, such as the Asian Weima - 13 hp, Subaru EX 27 - 9 hp, Honda 9 - 13 hp, will take root well on many "Agro" walk-behind tractors. s., Lifan 9 - 13 hp. That is, you can select spare parts for the Agro walk-behind tractor without having to source it from the manufacturer, if you know a lot about it. It won’t be too difficult to make a replacement, the main thing is to do everything in a clear sequence:

First of all, you need to remove the engine from the walk-behind tractor and remove the clutch.
Then remove the drive cup (under the conical shaft), replacing it with a machined cup (under the cylindrical shaft).
After this, you can install an Agro clutch on the imported engine, and then connect it to the transmission. At the same time, it is worth taking into account: the adapter with washer item 6 is not suitable for the old-style clutch, so the outer diameter will need to be reduced to Ф29 mm.

Change of oil

The oil should be changed immediately after break-in. Next, you need to replace it before the summer and winter seasons.

The sequence looks like this:

Drain the oil when the engine is not cool. You need to tilt the unit, unscrew the drain plug from the neck cap to fill the lubricant.
Wait until the liquid is completely removed.
Fill in new oil in the same volume and measure the level using a dipstick.

Attention! It is recommended to change the spark plugs along with the lubricant.

Motoblocks from Agro have proven themselves in the segment of inexpensive and high-quality devices, which are very popular and in demand among farmers and owners of summer cottages.

Motoblock device

The Mole walk-behind tractor is a frame structure divided into two half-frames. At the top there are tube-type handles and a bracket for mounting attachments located on the rear side. The controls are located on the handles: clutch and speed switch. Some models also have a reverse switch.

The device is equipped with four cutters, 2 external and internal, as well as a coulter. Additionally, a hiller for beds, a potato digger or plow, a pump for water supply, and a mower are installed.

A two-stage gear-type gearbox with a chain drive and an internal combustion engine, which are connected to each other by a V-belt transmission, are bolted to the supporting frame. Above them is the fuel tank.

The clutch of the minitractor is disengaged and is switched by a handle like on a moped. Engaging the clutch provides belt tension to transmit torque without slipping.

Mills for cultivating soil or wheels for moving loads or sharing with a plow are mounted on the output shafts of the gearbox. The cutters serve as the main working body and consist of a rotor with special knives. They rotate and cut, crush and mix the soil as they gradually move forward. The working depth will depend on the length of the opener used.

The milling cutter loosens the soil and mixes fertilizers more thoroughly than a plow. Shows good performance on heavy soils and virgin soil.

The Mole walk-behind tractor moves freely on built-in wheels. Before starting work, they are removed or raised, fixing them in the desired position. During the first 15 hours of operation, do not give full load. At this time, the parts are being run-in. With a “shock” rate of use immediately after purchase, the performance of the motor decreases.

Advantages

A walk-behind tractor with a Lifan engine has the following advantages:

stability of work;
high quality;
reliability;
low noise and vibration levels;
small overall dimensions;
the use of a cast iron sleeve to increase engine life;
ease of operation and maintenance;
large margin of safety;
long term of service;
affordable price.

All these qualities distinguish Lifan engines from other engines.

Main malfunctions of walk-behind tractors

Diesel and gasoline engines have different motor resources. For the former, the normal figure is 4000 m/h, but the latter are capable of providing only 1500 m/h. Despite this, diesel models of walk-behind tractors are not in high demand. After all, both when purchased and during operation they are much more expensive. Therefore, most likely, you are working with a walk-behind tractor equipped with a gasoline (carburetor) engine.

All breakdowns that may occur during the operation of agricultural mini-equipment can be divided into two categories:

Engine faults:

startup problems;
malfunctions.

Malfunctions of other components and mechanisms:

improper clutch operation;
breakdowns in the gearbox;
problems with the chassis;
control and automation malfunctions;
malfunctions of walk-behind tractor systems (cooling, lubrication, etc.).

In many ways, the success of repairing a suddenly broken machine depends on the correctness of the diagnosis. As for maintenance, it is carried out precisely in order to identify small faults that will later lead to serious ones.

If you do not have the necessary knowledge, premises, tools and materials necessary to service and repair the motor, entrust the work to a specialist!
