Do-it-yourself agros repair

In detail: do-it-yourself agros repair from a real master for the site my.housecope.com.

It is not worth starting a gearbox repair on a walk-behind tractor on your own if the operation of the unit and its device for a new user is a complete secret. Since the gearbox is a rather complex unit, you should not proceed to repairing it yourself immediately after detecting breakdowns. It will be better if professionals are involved in the repair of the checkpoint.

If an oil leak is detected from the gearbox, it means that the oil seals of the bearing units were incorrectly installed or worn out. They can be loose on the lids. Damaged gaskets may appear underneath. If the air valve (breather) is clogged, it is necessary to clean it and bring the oil level to normal. Oil leaks can be eliminated by replacing or properly installing oil seals or gaskets. Tightening the cover bolts will also help to solve the problem.

If the automatic transmission mechanism has ceased to function normally, then the following types of malfunctions may occur:

Violation of the kinematic connection inside the gearbox.
Spontaneous engagement of gears or lack of fixation.
Oil leaks on the shift shaft.
Dysfunction of the semiaxis separation mechanism.
Lack of gear shifting.
Gearbox jamming.

If the kinematic connection inside the gearbox is broken or the sprocket in the block breaks, it is necessary to disassemble the gearbox in order to replace the problem sprocket. Oil leakage on the selector shaft may be caused by excess oil in the gearbox, so check the oil level. If the welding connection of the gear breaks, disassembling the gearbox, change the block shaft. Drain excess oil, check the degree of wear of the working edge of the oil seal on the shift shaft, disassemble the gearbox and replace the part.

The reason for the lack of fixation of gears or their spontaneous shutdown is a violation of the adjustment of the gearshift mechanism. When making repairs, loosen the screws that secure the switching mechanism board.

After that, turn on the first gear and tighten the screws that secure the board. For example, having made a mini-tractor with your own hands, it is imperative to monitor the correct adjustment of the drive by changing the tension of the control cable for disengaging the axle shafts. To fix the breakdown of any element of the drive shaft disengagement inside the gearbox, you should disassemble the gearbox, replacing the broken parts.

If a broken spring or worn shift plate retainers are found, replace the damaged parts by adjusting the shift. If it is absent, the shift cradle or the threaded piece of the shift knob may be cut off. After disassembling the gearbox, it will be necessary to replace the defective parts. If there is no gear shifting, disassemble the gearbox and replace the worn gear shift fork. If the cause of the gearbox jamming is an open circuit, then it should be disassembled and the chain replaced.

If the operation of the gearbox is accompanied by increased noise in the gearbox, then the reason for this may be a lack of oil in the gearbox device or a mismatch in the quality of the lubricant with the required parameters. The choice of oils must be of the appropriate brand, they must have a certain purity. If there is any problem, you will need to change the oil or top up the gearbox.

The occurrence of noise in the transmission units of the walk-behind tractor can be caused by a weak tightening of the fasteners, therefore it is necessary to inspect the fasteners by tightening them properly.

Frequent noise is caused by worn gears and bearings. This can lead to more serious damage to the gearbox of the walk-behind tractor. It is not difficult to avoid their appearance if you do a timely inspection and repair of the walk-behind tractor. It consists in the usual replacement of worn out assemblies and parts.

If there is a heating of the transmission units of the walk-behind tractor, the following main reasons for this malfunction are distinguished:

Lack of transmission oil in the crankcases.
Worn bearings.
Mismatch of the oil condition with the required parameters.

There can be two reasons for correcting deficiencies:

bearings replaced;
adding or replacing oil.

In order for a gearbox or a homemade gearbox to last longer, it is necessary to periodically check the oil level in them, fearing a sharp change in load.

Signs of violations associated with difficulties in switching speeds, spontaneous shutdown, violation of the process of turning on the unit, arise for the following reasons:

Deterioration of parts.
Shaft spline abrasion.
Incorrect clutch adjustment.

Rolling (wear) of the ends of the engaging gears causes two problems, leading to self-deactivation or incomplete engagement of speeds.

If the factory or home-made box works with any violations, it will be necessary to disassemble it, as well as dress the gear teeth by grinding. If the wear is large enough, new parts must be installed. To adjust the axial position of the shafts, additional installation of circlips is required. In certain cases, it is necessary to replace worn bearings and rings.

Adjustment of the gearbox clutch for the walk-behind tractor should be carried out in a timely manner, otherwise it will stop squeezing out and difficulties may arise when shifting gears. Difficulties in controlling the walk-behind tractor often arise among beginners, who, due to inexperience, can lower the clutch lever too early when changing gears.

Like any technique, a walk-behind tractor requires timely maintenance and repair. And it is advisable to entrust their implementation to specialists who have the necessary tools and equipment and know their job well. However, if you are also familiar with the device of internal combustion engines and understand the topic of mechanical engineering, then you can do a lot of what may be required to restore the operability of the machine yourself.

Diesel and gasoline engines have different motor resources. For the former, the normal figure is 4000 m3 / h, but the latter are capable of providing only 1500 m3 / h. Despite this, diesel models of walk-behind tractors are not in high demand. After all, both when buying 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 arise during the operation of agricultural mini-equipment can be conditionally divided into two categories:

Engine malfunctions:

startup problems;
malfunctions.

Malfunctions of other units and mechanisms:

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

In many ways, the success of repairing a suddenly out of order machine depends on the correctness of the diagnostics. With regard to maintenance, it is carried out precisely in order to identify small malfunctions, which subsequently lead to serious ones.

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

If attempts to start the walk-behind tractor were unsuccessful, this means that there are malfunctions in the engine or starting system. In order to determine the source of the breakdown, you first need to check the spark plugs.

If the spark plugs are dry, this means that the fuel mixture is not entering the engine cylinders. There may be several reasons for this:

there is no fuel in the tank;
the fuel supply valve is closed;
the hole in the gas tank plug is clogged;
foreign objects have entered the fuel supply system.

To fix problems with the fuel supply, you must:

Fill the tank of the walk-behind tractor.
Open the fuel cock.
Clean the drain hole located in the fuel filler cap.
Remove the fuel cock, drain the fuel tank and rinse it with clean gasoline. After that, remove the connecting hose on the side of the carburetor and blow it out together with the carburetor nozzles without disassembling the latter using the fuel pump.

If fuel enters the carburetor but does not reach the cylinder, the problem is with the carburetor itself. To eliminate it, this unit must be removed, disassembled and cleaned. Well, after that - assemble and install in place. Therefore, before performing all the necessary manipulations, it does not hurt at all to refresh the memory of the device and the principle of operation of the carburetor.

In the event that, when checking the candles, they turned out to be wet, i.e. fuel is supplied normally, but the engine does not start, the problem may be as follows:

Failure of the ignition system:

there is a characteristic carbon deposit on the spark plug electrodes (it is necessary to clean the candles with emery, after which they should be rinsed with gasoline and dried);
the size of the gap between the electrodes does not correspond to that specified by the manufacturer in the engine operating manual (the gap is adjusted by bending the side electrode to the required dimensions);
insulators for spark plugs or high-voltage wiring are damaged (defective plugs and wiring must be replaced);
the STOP button is shorted to ground (for normal engine start, the short circuit must be removed);
contacts in the angles of the candles are broken (contacts should be put in order);
the gap between the magnetic shoe and the starter does not correspond to the standard value (gap adjustment is required);
defects are found on the stator of the ignition system (the stator must be replaced).

Air leaks through the seals of the carburetor, spark plugs, plug and cylinder heads, as well as the carburetor and engine cylinder connections.

If a leak is detected in the connections, it is necessary to tighten the fastening bolts, tighten the spark plugs and check the integrity of the gaskets between the plug heads and the cylinders.

Incomplete closure of the carburetor choke.

To eliminate this problem, it is necessary to ensure free movement of the damper by checking the quality of the drive. If jams are found, they must be eliminated.

Compression and carburetor malfunctions

It so happens that the launch is carried out, but its process is significantly complicated. At the same time, the engine of the walk-behind tractor is extremely unstable and cannot develop power sufficient for normal operation.

The reason for this may be loss of compression, which can be identified by:

soot on the working surfaces of the valves, as well as the seats of the cylinder blocks;
deformation of the intake valve;
wear of the piston rings.

In order to restore compression, you must:

Check the technical condition of the engine timing mechanism, clean the parts contaminated with carbon deposits, and if there are any defects, replace them.
Check the condition of the piston rings and replace defective components.

If, during engine operation, black smoke comes out of the muffler, and an excess of oil is detected on the spark plug electrodes, or they themselves are covered with carbon deposits, this means that:

an oversaturated fuel mixture is fed to the carburetor;
the sealing of the carburetor fuel valve is broken;
the oil scraper ring of the piston is worn out;
the air filter is clogged.

To fix this problem, you should:

adjust the carburetor;
replace the leaky valve;
replace worn piston rings;
clean or replace a defective air filter.

In the event that, when the engine is running, light smoke comes out of the muffler, and the spark plug electrodes are dry and covered with a white coating, this means that a lean fuel mixture enters the carburetor. This problem is eliminated by adjusting the operation of the carburetor.

Units and components of motors that are installed on agricultural mini-machinery are exposed to significant loads. They can also fail during the operation of the unit, which will very quickly lead to serious failures.

If suspicious noises, jerks and irregularities in the operation of the walk-behind tractor systems are detected, it is very important to immediately turn off the engine, and then let it cool down - only after that it will be possible to fix the problem.

If, during operation, the motor starts to gain momentum on its own, i.e. is "running out", most likely this means that the fastening of the regulator and traction levers is loose. In this case, the user will have to readjust the motor control drive.

Sometimes, when the throttle is fully open, the engine does not accelerate when the throttle is pressed, but on the contrary begins to lose power until it stops completely. This is a clear sign of overheating, so the walk-behind tractor must be turned off and wait until its components have completely cooled down. After that, you should check the oil level in the crankcase, and also check the cleanliness of the ribbed surfaces of the blocks and cylinder heads.

Under increased engine loads, it can jam. There may be several reasons for this:

not enough oil in the crankcase;
a nadir formed on the lower head of the connecting rod;
the connecting rod or oil spray is completely out of order.

If the motor of the walk-behind tractor is jammed, it will have to be disassembled and the condition of the main units and components should be checked: faulty, deformed, melted, etc. subject to replacement.

What to do if the motor block motor works intermittently and does not develop the required power? There may be several reasons for this behavior:

Air does not enter the carburetor, which means that the fuel does not burn well - the filter will have to be cleaned or changed.

Fuel residues and combustion products form a thick deposit on the inner walls of the muffler, which must be removed.

In this case, the assembly will have to be removed, disassembled and properly cleaned all of its components. After that, the carburetor must be assembled and properly adjusted.

Wear of the cylinder-piston group.

Temperature and high loads do their job, and even the most durable metal wears out and deforms over time. Such parts should be replaced immediately, otherwise you can pay for this with irreparable damage in the engine itself.

Damaged ratchet housing or ratchet

The presence of this problem is indicated by the lack of movement of the crankshaft when the engine is started. To replace the clutch housing and ratchet, you will have to completely disassemble the starting block.

Loosen the screws securing the starter housing to the engine housing.

If the starter cord does not return to its original position, the starter motor must be adjusted. To do this, the screws are loosened and the position of the knot is set by hand so as to ensure the normal return of the cord.

A fairly common reason for the lack of a return stroke of the starter cord is the failure of the starter spring - it will have to be replaced.

The service life of any equipment is significantly increased by competent maintenance of its main units and components. The promptness of replacing worn-out spare parts is also of great importance. Therefore, in the event of the slightest malfunctions and malfunctions, they should be eliminated immediately - as a result, this will prevent much more serious and expensive problems.

Sooner or later, any technique fails in the system. The reasons for such troubles can be very different: failure to comply with the operating conditions, wear of old parts, poor-quality assembly of the unit itself, and so on. In any case, whichever of these reasons is, the equipment needs to be repaired. Today we will talk about all kinds of malfunctions with Agro walk-behind tractors. We will try to figure out the repair without contacting service centers for this.Motor faults fall into two categories:

The engine won't start at all.

The engine works, but intermittently.

If the diesel engine on the Agro walk-behind tractor does not start: reasons and solution

Before starting the engine on a walk-behind tractor, you need to conduct a thorough inspection of all equipment. Are all parts and fasteners in place as they are secured.

One of the reasons for such a problem may be stagnation after a cold winter, which leads to the following problems:

contacts are oxidized;
oil and fuel are watered;
nozzles in the carburetor are clogged;
the insulation of the wires may be broken.

Another reason may be outdated oil that needs to be changed urgently.

A huge nuance is the correct fuel for a particular motor model. If it is 2-stroke, then it is necessary to fill in such a mixture in appropriate proportions.

How to determine for an Agro walk-behind tractor that a diesel engine does not start precisely because of malfunctions of components and mechanisms. Everything is very simple, if after the next series of operations the engine fails at startup, then the problem is in the mechanisms:

preparing fuel;

we feed it into the cylinder;

turn on the ignition;

we release all waste gases.

To determine the cause of a breakdown in the nodes, you must first of all carry out a detailed diagnosis. The diagnostics made will be able to identify the true cause of the malfunctions, and this may be:

the fuel supply path may be clogged;

broken carburetor;

the air filter may not let air in;

the hole in the gas tank cap is clogged.

It is also important to pay attention to the candle, if it is dry, it means that the fuel does not enter the combustion chamber. What we do in this case:

Drain the gasoline completely.

We clean and rinse the tank.

We clean the filter.

We blow out the fuel supply hose.

We blow out the jets in the carburetor.

We fill the tank.

We open the tap.

We are cleaning the respiratory canal.

The cause of a breakdown in the ignition can be hidden in the following parts: a candle, a magneto, a cap and a high-voltage wire. How to troubleshoot various issues:

In the absence or weak spark, it is necessary to adjust the intermediate gap and the condition of the electrodes. The adjustment gap should be standard 0.8 mm.

If a low compression ratio is found in the cylinder, then you just need to change the worn parts.

When adjusting the valves, it is imperative that both inlet and outlet valves fit snugly and tightly to the seat.

Cleaning the muffler.

Before finding the true cause of the malfunctions of this part, it is worthwhile to carry out a number of actions:

We turn on the ignition and check the presence of fuel in the tank.

Open the fuel cock.

Check if the carburetor choke is closed.

Now you need to check if the fuel goes directly to the carburetor. To do this, simply disconnect the fuel hose from it and see if the gasoline runs freely. If the gasoline runs off badly in a thin stream or nothing runs at all, the tank air valve cap is clogged. And then it just needs to be cleaned.

Basically, the essence of such a repair is to correct the places where the springs are attached or an elementary replacement of several parts. Problem solution:

If the cord breaks, we replace it.

If there is no hook at one of the ends of the annular spring, then it must be bent or the spring must be replaced altogether.

Read the diagram carefully, and carry out all repair work only relying on it. Image - Do-it-yourself agros repair

Such a breakdown will be indicated by a stop of the rotation of the power take-off shaft of the walk-behind tractor, and the gearbox itself will simply wedge. It is possible that the chain itself has broken, then it just needs to be replaced and the PTO will resume its work.
Also, very often, owners of walk-behind tractors have problems with adjusting attachments. For example, adjusting the plow on a walk-behind tractor involves the following actions:

We fix the hitch with 1 pivot, where the play in the horizontal position should correspond to 5 ° - 6 °.
We adjust the plowing depth. The norm will be somewhere 5 - 7 cm deep into the ground.
Adjusting the angle of attack. We place the tiller with a plow on a flat surface. Unscrew the adjusting screw so that the plow touches the ground. And unscrew the screw back until the back of the canopy rises 2.5 cm from the ground.

These are the main points of plow adjustment that need to be done when installing it.
Of course, this kind of breakdown of the Agro walk-behind tractor, such as turning on the power take-off shaft, adjusting the clutch, can be eliminated with your own hands without much difficulty. Also, in the event of a malfunction of the Agro walk-behind tractor, you should refer to its operating manual, where all problems with such equipment should be described in more detail. If you still understand, for example, you need to disassemble the imported engine of your unit, that you are not sure that you will do it correctly, then it is still better to contact the specialists. Still, in service centers they can make detailed diagnostics and establish where the problem is with an accuracy of 100%. So, in cases of doubt, it is better to turn to professionals.

I propose here to throw off information about analogues / replacement of spare parts, methods / methods of repair, disassembly / assembly, configuration, etc.

transfer to AI-92, factory method, -

when disassembling the clutch, I use 2 studs M6 * 100 mm:

I screw in instead of 2 bolts, counter with a nut from below to prevent rotation, 2 washers on top and screw in a nut;
I unscrew the remaining 2 bolts;
alternately drive the nuts (it is better to use an elongated head with a ratchet) and halve the clutch;
assembly in reverse order.

Does anyone know about a rotary plow at AGRO

Good day! After six months of non-operation of the Agro walk-behind tractor, the clutch stopped working (the clutch lever is pushed out).
Has anyone encountered such a situation? What happened after such a stop and how to fix the problem? Tell,
best regards, Sandy.

Sandy, Wheels are stuck on the move, remove the engine and see the clutch.

Sandy, this is from a little work with a walk-behind tractor or moisture. The discs are stuck to each other. I have never stuck after half a year of inactivity. Now MB works in winter, I use AGRO with dumps for cleaning snow. If the walk-behind tractor works a lot in the spring-autumn season and its clutch engages smoothly enough, and without noise, then it will not stick during the winter. This is the same as with a plow, if it shines like a mirror, then the earth does not stick. If the metal disc is matte, not polished by long smooth operation, then the clutch pad is also rough and such a clutch will stick faster than with a mirror disc where the pad corresponds to it.

And without removing the engine. unable to move the disks under load?

Sandy, I think not, the neighbor's ones were slightly disconnected.

I have been using Agros since 2001, a year later I worked out the method of setting the starting damper on my native carb for work with variable loads (start with a loaded trailer, snow blower on caked or wet snow, etc.), (and even rearranged the CRO-carb thrust on the lever CRO into the hole closest to the axis for the spring from the throttle cable lever, reaming it to 5 mm):
on a warm engine and a tuned carb with an open start damper, we set the maximum speed and, by covering the start damper, we achieve stable operation with smokeless exhaust (usually at an angle of up to 30 degrees)

Sandy wrote:

Sandy, it's easy to shoot there - unhook the wires and the gas cable, unscrew 4 nuts and go.
you can then drill a small hole in the clutch housing from below to drain the condensate

in the first year of Agros's life, the speed rod jammed - it was apparently not hardened, I had to disassemble the gearbox, grind off the rolled beads on the rod and harden it, and immediately did:
neutral on the direction selection rod - groove in the middle of the rear and front. What are the advantages: without removing from the desired gear, the neutral is easily turned on with the direction selection lever, it is easier when starting or rolling a muffled MB.

to facilitate starting the MB engine, I replaced the clutch handle with a brake lever with fixation from a scooter, now fixing it in a compressed state is easier to start

Hello everyone, there is a well-worn agros walk-behind tractor, because of this there are many questions.
1) How many watched the Internet and did not understand the walk-behind tractors are called Agro or Agros? What's the older name? My plate is all rusty and besides, I understand the serial number, you can see the embossed numbers 10 and 01, as I understand it, the release date is October 2001? or not?
2) While disassembling the walk-behind tractor to tint, I came across some kind of self-made electrical circuit, since I am the same pro in electrics, as in nuclear physics, I ask your friends for help. The walk-behind tractor has a flashlight and a toggle switch, and besides, I used a new agros and I know to turn off the engine you need to disconnect the cap on the steering column, this instance, due to its being killed, does not have such a device, there this pin is closed with a bolt, and to turn off the engine you need to connect 2 wires, so as I understand it, this whole self-made electrical structure appeared. I want to get rid of it, return the walk-behind tractor as much as possible to the factory configuration, tell me if it is possible to do something with it, provided that I want to remove the flashlight but leave the jammer. I drew the diagram as best I could and attach the pictures.

wires that muffle the engine and the bolt in place of the factory muffler

electrical board in file, apparently for rain protection

ignition coil and block with board

3) As far as I remember, with a new agros, when the gears are turned on, the shift knob must be inserted into the groove and you know which gear is on, but this one has no grooves, how to understand which gear you have turned on?

Motoblocks are able to significantly facilitate work on a personal plot. This is a compact agricultural machinery with high functionality and versatility. With its help, you can not only loosen the soil, but also carry out basic activities for the care of plants and harvesting.

Like any other technique, walk-behind tractors sometimes fail. Fortunately, they have a relatively simple design, and you can even carry out simple repairs with your own hands. To do this, you need to learn how to determine which part of the walk-behind tractor is out of order, and what needs to be done to restore the operation of the equipment. Our article will help you with this, which not only describes the principle of operation of the walk-behind tractor, but also the main causes of equipment malfunction and how to eliminate them.

Most of the models consist of the same parts, so you can do the repair of the main components yourself.

Figure 1. Standard drawing of a walk-behind tractor

Each walk-behind tractor consists of a base frame, a gasoline or diesel engine, a fuel tank, a rotor for attaching cutters, wheels and a bracket for fixing attachments. The most important component is, of course, the engine, on the successful operation of which the operation of the equipment will depend (Figure 1). In addition, modern models have fuel supply, cooling, ignition and gas distribution systems, and the occurrence of malfunctions in them can also lead to a shutdown of the unit.

The main function of the walk-behind tractor is to loosen the soil using special cutters that are attached to the frame of the device.

Note: Unlike a conventional plow, the cutter does not overturn the soil and prevents soil erosion.

In addition, the technique can be used to loosen row spacings in the process of growing agricultural crops, and special attachments are useful for harvesting. Simple models (cultivators) consist of several wheels and handles that are used to control the machinery. On the handles there are buttons necessary for control. More powerful and modern models are mini tractors without a cab. In this case, control is carried out by buttons and pedals located on the dashboard.

Despite the fact that walk-behind tractors are produced by a wide variety of manufacturers, it is customary to divide all such equipment into types depending on weight and power (Figure 2).

According to this criterion, walk-behind tractors are:

Ultralight - weighing up to 15 kg;
Lightweight (about 40 kg);
Medium - from 45 to 60 kg;
Heavy (over 60 kg).

Figure 2. The main types of machinery and attachments

As a rule, all types of equipment are supplied with an internal combustion engine with a capacity of 1.5 to 10 horsepower. This is necessary in order for even the ultra-light model to successfully cope with loosening the soil in areas with heavy and dense soils.

Since the main part of any technique is the engine, the main number of breakdowns is associated with it (Figure 3). In some cases, poor engine performance may be associated with poor-quality fuel or dirty air filter. There are also cases that the engine does not work properly due to insufficient heating, malfunctions of the ignition system, carburetor or pistons.

Figure 3. Main engine parts

We will try to understand the main types of damage to the walk-behind tractor, which can be eliminated with our own hands. However, if you are not confident in your own abilities or fear that it is impossible to eliminate the malfunction on your own, it is better to contact a specialist.

If the engine does not start when you try to start, there may be a problem with the engine itself or its starting system.

To troubleshoot fuel supply problems, do the following:

Check the spark plugs: if they are dry, there is no fuel entering the engine cylinders. Such a malfunction can occur when blockages form in the gas tank cap, debris gets into the fuel supply system, when the supply valve is closed or the banal lack of gasoline.
Refuel the tank and try to start the engine again.
Check the fuel cock: if closed, it must be repositioned to open.
Clean the fuel tank drain hole.
Drain the gasoline tank, remove the fuel cock and rinse it with clean gasoline.
Remove the connecting hose near the carburetor and blow it out (together with the jets).

If all these manipulations did not help, and the fuel enters the carburetor, but does not enter the cylinder, then the malfunction is in the carburetor and this part must be carefully examined.

A common cause of carburetor malfunction is blockages. In this case, it is enough to disassemble the part, remove the source of pollution and reassemble. The instructions, which are necessarily provided by the manufacturer, will help you with this (Figure 4).
