Do-it-yourself mole motor-cultivator repair

In detail: DIY repair of a motor-cultivator mole from a real master for the site my.housecope.com.

Before proceeding with the self-repair of the Mole motor-cultivator, you need to know whether it is subject to warranty service. If the warranty has not yet expired, contact the appropriate workshop. There the equipment will be repaired and the warranty will be extended for a certain period of time.

You need to know that after the first turn-on of the walk-behind tractor, the full load is not given to the engine. The instructions indicate the run-in period, since all parts must be lapped, otherwise the engine and gearbox will have to be repaired in the near future.

But if your walk-behind tractor is already quite old and does not have warranty service, you can try to make a small repair of the mole motor-cultivator with your own hands. He is not very difficult and even a not very experienced person will cope with this task. "Mole" is a simple device. In order to do everything correctly, first read the instructions and the block diagram, because knowing the device of the machine, you can also make its repair.

When we talk about repairing the Mole walk-behind tractor, it is worth listing the following breakdowns and ways to fix them:

Defective ignition - Mole walk-behind tractor often breaks down. First, check the candle - it is unscrewed and inspected. A dry candle indicates that the fuel mixture does not enter the cylinder. If the spark plug is very “wet”, “bleed” the engine with a recoil starter - this way you can dry the cylinder. If there is a lot of carbon on the candle, clean it with fine sandpaper and gasoline.
Electrode gap usually 0.8mm, adjust if necessary.

Defective ignition is a common reason for the repair of the "Krot" motor-cultivator

No spark... So, the candle is faulty, just put a new one (LINK on candles with Aliexpress). It is also possible that there is no contact in the electrical circuit or the gap between the magnetic circuit and the ignition coil is broken.

The ignition of the Mole walk-behind tractor depends on condition of petrol hoses, isolation of high-voltage wires and their connections. Check everything carefully, flywheel plates SHOULD NOT touch the magnetic cores of the magneto. Make sure there are no touch marks.

The air filter needs to be checked... If it is dirty, there is not enough air entering the carburetor. Even a dirty muffler affects engine power.

Can't find your ignition failure? Contact a specialist, you cannot cope with a serious problem on your own.

We give a small recommendation on the selection of a specialist for the repair of "Mole" - site Profi.ru... Choose your city and look for a master, the likelihood of finding a good specialist is very high.

Most often, the owners of cars of this brand are faced with engine problems, for example, it does not start or its work is unsatisfactory. Among the signs of a breakdown: spontaneous stop, power is not gained, interruptions are heard.

Here's a quick guide on how to spot a breakdown:

Check the ignition;
Make sure there is fuel in the gas tank;
If you are in doubt about the flow of fuel to the carburetor, check the fuel filter;
Clean it if necessary;
Start a cold engine;
The carburetor choke must be closed.

If you cannot find the cause of the malfunction of the Mole motor-caster and fix it yourself, contact a specialist

To prevent malfunctions of the Krot motor-cultivator, you need to know the elementary rules for its storage and operation. They depend on how long the equipment will be inactive.
If you will not use it for a long time, then here are some rules:

It is necessary to start the engine so many times that carburetor left empty.
Machine parts that move and rotate must be neatly greased with quality oil.
Daily maintenance necessarily.
Walk-behind tractor surfaces wiped daily with a ragsoaked in a fuel mixture.
If any parts fail install new parts.

If you want to operate the Krot walk-behind tractor for a long time, without repair, be sure to undergo maintenance. Don't buy cheap, left-handed parts. Only original spare parts will ensure the high-quality operation of your equipment after repair. Regular inspection and maintenance guarantees a long service life.

If you do not yet have a Mole cultivator, but you are thinking about buying it, be sure to watch the most useful video about all the advantages of this machine:

How to replace the engine on the Mole cultivator, 4-stroke engine on the cultivator

It will be about repairing a mole cultivator. They asked me to repair a 94-year-old mole, which did not even work in the running-in hours (20 hours). When you try to start it, it shoots a couple of times and can even work for a couple of seconds. While I'm sinning on the ignition system. Maybe someone knows how to check it (there is a spark, but rather weak) and what problems may arise with the magneto.

In shops (?) And in the markets, the sellers of spare parts for Russian technology have a device for checking the magneto, remove and take it, they will check the sparking. I checked my last modification of the magneto in the Kiev market. I think in other markets the merchants have it (adapted)

Check out the magneto! With long interruptions in operation, the magneto coil becomes unusable.

I was lying for 5 years with a punctured thyristor

, kirdyk rarely comes to the coil, before the conductor dies. I changed the thyristor and it all worked

According to the instructions, it is necessary to pour M8V in a ratio of 1:20, but the old mole in the new instructions for similar models of moles can be used MGD14M 1:40. Is it possible for me to pour gasoline with MHD oil into the mole and in what proportion to pour it.

wrote:

Need to! Fuel oil is excellent and time-tested. M8 - kills motors slowly but surely.

The spark was gone, the magneto was checked in the store, everything is fine! What could be. Can flywheel magnets demagnetize? what is the problem?? Tell me who knows! Thanks!

Spark can be lost due to high voltage wire and / or cap. I advise you to try at the beginning without a cap. If you do not feel sorry for yourself, you can use your hand as a candle (this is more reliable, you will notice even the weakest spark).

Who knows, tell me how to make the gap on the new piston rings.

Lock gap?

similar to a motorcycle, 0.2-0.35 mm

There will also be such a question: the instructions say that the ignition angle should be 19 degrees to TDC. It is easy to translate into mm, but I do not know at what point the spark is formed. How to determine by the position of the magneto rotor at what moment the sparking will occur.

This place in the manual has always touched me

.
Sparking was discussed here like, for memory

: when the coil is opposite a magnet with reverse polarity

I almost forgot

At the factory, when checking for MB-1 blocks, they pose a risk for the moment of sparking

There is a risk. But on the carter it is at the top, and on the magneto at the bottom. And there is no way to set it exactly.

There is a motor-cultivator "Mole" MK-1A-01Ts. Replacement of the carburetor is required. It has a K-41K type carburetor. Question: is it possible to replace it with a K-60 carburetor, and what limits will be required?

Friends.
After wandering through the pages of the forum, I proudly noted that among us there are a lot of owners of this hardworking, unpretentious and very easy-to-use * iron horse *

Such an irreplaceable helper in the garden and vegetable garden. That's just, everything that is connected with its operation is scattered on different topics.

And sometimes, it is quite difficult to find answers to questions of interest to all of us, on how to operate, maintain, add. equipment, tuning

purchase of spare parts and so on.
I propose to create a separate branch dedicated to the * KROT * motor cultivator * of its various modifications, and in it to discuss everything that interests us so much. And the Lord Moderators, to transfer into it everything that is connected with it - from other topics.

Tillers play an important role in rural life. After all, it has become not only much easier to process areas with such units, but also much faster. And using attachments: plow, cultivator, etc. such a unit has completely turned into a mini-tractor. This is precisely what caused their immense popularity in our time.

This technique, like in principle any other, sooner or later fails. There may be several reasons for this:

Incorrect operating conditions.
Wear of parts.

In this article, we will analyze several cases of breakdowns of the Mole walk-behind tractor and the essence of their repair. We will tell you how to make repairs with your own hands, and what spare parts for the walk-behind tractor we need.

Spare parts for the walk-behind tractor can be easily replaced in case of wear. In addition, finding them today is not a problem at all. Today there are a huge number of spare parts for a walk-behind tractor in many online stores. There you can find any part for the engine, as well as for attachments (plow, rotary tiller, etc.).

The main failure of oil seals is that they leak oil. In this case, you need to urgently replace them.In addition, such a part is quite inexpensive. After all, if the oil from the gearbox of the walk-behind tractor flows out completely, then the walk-behind tractor will simply stall and be defective. How to replace oil seals:

We first need to remove the cutters from the power take-off shaft.
We clean the PTO shaft and covers from oil and dirt streams, debris.
Remove the cover. To do this, unscrew all the fastening bolts, tap the cover and only then can we remove it.
We are replacing the oil seal.
Wipe the connector dry.
If necessary, sealant can be applied to the connector.
We attach the cover in place.

The most common cause of manual kick breaks is unbent spring attachment points. Sometimes there are times when you need to replace the starter cord. To find out the real reason for the breakdown of the kickstarter, you need to disassemble part of the walk-behind tractor.

Before proceeding with the repair, you need to acquire its circuit, which you need to rely on when disassembling. So let's get started:

We remove the kickstarter block.
In front of you there will be a drum, in the center of which there is a washer, you need to unscrew it.
Next, we remove other fasteners and carefully check all the details.

What can be the breakdowns of the kickstarter:

reeds do not work;
the cord broke;
the hook in the center of the reel is torn off;
one of the ends of the spring has unbent.

If the cord is torn, it must be replaced with a new one. There are 2 hooks at the ends of the ring spring. If one of them does not have this, you need to warm up the metal and bend it with a crochet. It is also possible that the spring ring can be completely replaced.

How to make and correctly equip the reverse speed on the Mole walk-behind tractor?

Take a pulley from the Volga, for example.
We unscrew the nut, put the elongated nut.
An elongated nut tightens the primary pulley, which is standard.
Then we screw the bolts into this nut, and thus the second pulley from the Volga is pressed.
We use the pressure roller from the timing belt tensioner of some foreign car.
We attach 2 springs and a cable.

That is, in principle, the whole scheme of such a design. It is worth noting that even plow-type attachments will not interfere with the rear speed, and with any canopy, the traction will be excellent, be it a plow or a rotary tiller.

As for the repair or modernization of the ignition on the Mole walk-behind tractor, in this case we suggest contacting specialists, since these malfunctions cannot be called simple. In them, you need not only to be well oriented in the diagrams, but also to know how to connect all the parts in such a way that the ignition is serviceable.

But still, if you understand this area, then you can safely proceed to modernizing the ignition with your own hands. First of all, prepare all the necessary spare parts for the walk-behind tractor, which will be needed for repair. What is needed for such a revision:

We take an ignition coil, it is possible from a car, with a multiple reserve and several times more powerful than the previous spark.
We mount the ignition coil on the steering plate on the Mole walk-behind tractor.
In place of the native coil, we install the second generator.
Install the flywheel with 4 magnets. Moreover, each coil of the generator has its own diode bridge.

All owners of walk-behind tractors should remember that by adhering to all the conditions for servicing walk-behind tractors, you can extend the life of your unit. The same applies to timely continuous diagnostics of equipment and regular oil changes. By doing this work, you can easily ensure a long service life of the Mole walk-behind tractor. And in case of breakdowns, finding spare parts for both the canopy and the Mole walk-behind tractor (plow, cultivator, etc.) will not be a problem.

Motoblock is one of the most important types of agricultural machinery. They are used in almost all types of work related to land cultivation. Each land owner chooses the most suitable model for himself. Consider a walk-behind tractor from the Mole company, which is quite popular in the agricultural sector.

The Krot walk-behind tractor has long occupied a good and solid position in the agricultural machinery market. Many summer residents and landowners use the technique of this particular model. In order for the unit to work for a long time and provide a high-quality result, each device needs decent maintenance: change fuel and lubricant (use only high-quality technical fluids), before starting work, take into account that the Mole walk-behind tractor engine needs a trial run. It is necessary to regularly diagnose the unit for breakdowns, timely replace worn out, outdated or broken parts.

Contactless ignition.
Fuel tank designed for 1.8 liters of hot.
The presence of an air filter that prevents foreign particles from entering the engine mechanisms.
Carburetor model K-60V.
The starter, which is located on the frame, works from a manual start.
The engine is 2.6 liters, giving 6 thousand rpm at maximum power.

Of course, time and stress do their job. Any walk-behind tractor, even the highest quality one, sometimes needs restoration or replacement of component parts. A special part of the unit is the engine, and its repair is brought to the fore in any case. You can carry out repair processes with an engine with your own hands.

To replace the gearbox oil seals yourself, you need to stock up on a fair amount of tools. From the first time, you may not understand which part is the oil seal, but it will immediately become clear when oil begins to flow from it.

One of the most capricious mechanisms is the kickstarter. To repair the kickstarter, you will need to purchase lubricant, arm yourself with a tool, remove the cover on the variator, unscrew the bolts on the starter and get it out. After that, the part is inspected, consumables (oil seals, gaskets) are changed, the product is lubricated and installed back.

It will also be difficult to replace the rings in the engine. Here you need to have the technical skills and experience with the parts of the walk-behind tractor. The following scheme will help in the repair.

Due attention should be paid to the accessories for this unit. It is necessary to select it correctly, since it gives a certain load to the engine. The plow or reversible plow is the most commonly used accessory. All the nuances should be taken into account when working with them.

The neighbor gave the engine away from the cultivator, the mole. Cleaned and disassembled. See the photo of the piston seizure, cylinder in this condition. Is it worth changing only the piston, will the engine work after that, or is it necessary to completely change both the piston and the cylinder, please tell me?

Oksana Change the piston completely, otherwise the new piston with rings will quickly snag.

Vyacheslav aha, and the grandmother asks to die on the treadmill.

Julia 1. Cylinder for boring, already with a piston, which is below)))
2. Buy a piston with oversized rings ...
3. Assemble and rejoice, I think that the bushing on the crankshaft should also be changed ...

Jul 21, 2014 - Do-it-yourself mole-cultivator repair. that after the first turn on of the walk-behind tractor, the full load is not given to the engine.

Do-it-yourself repair of a motor-cultivator mole. stroke engines with low fuel consumption, the repair of such products is performed much less frequently.

In Russia, motor-cultivators of the "Mole" type have been produced for a long time. The first model of the MK-1 "Krot" motor-cultivator was manufactured as a single-purpose machine for soil cultivation. To date, the technical capabilities of motor-cultivators have been significantly expanded and even mini-feed preparation equipment has been developed for them. Externally, motor-cultivators resemble walk-behind tractors and the main structural units for both are the same.

Motor-cultivator MK-1 "Krot":

1 - working body (rotor); 2 - reducer; 3 - knife of the working body; 4 - gas tank; 5 - button "stop" for stopping the engine; 6 - clutch control lever; 7 - carburetor throttle control lever; 8 - engine; 9 - opener; 10 - support; 11 - frame; 12 - transport wheel

The main units of MK-1 (see fig.) Are the engine with an integrated gearbox (described below), transmission, control system, working bodies, opener, wheels.

The transmission provides the transmission of torque from the single-stage engine reducer to the working bodies and consists of a V-belt transmission and a lower two-stage reducer. The V-belt drive also performs the function of a clutch. Working bodies are installed on the output shaft of the gearbox chain drive.

The control system consists of two handles adjustable in length and width. On the left of them is the carburetor throttle control lever, on the right - the clutch control lever. To stop the engine, the control system has a Stop button.

The working bodies are made in the form of rotors, each of which has four specially shaped knives. The milling drum with a diameter of 320 mm is assembled from two or four rotors. In the first case, the width of the processed strip is 330 mm, in the second - 580 mm. If you additionally install two more rotors, which allows the design of the walk-behind tractor, then the width of the processed strip will be 830 mm. The milling drum rotates at 85 rpm and works the soil up to a depth of 20 cm (depending on setting).

The forward movement of the walk-behind tractor is carried out due to the rotation of the working bodies - rotors, which simultaneously perform the technological process.

The coulter is installed behind the working bodies and acts as a regulator of the depth of soil cultivation. The coulter is adjusted in height in steps.

A pair of wheels in the form of disks with a rubber rim has no drive and serves only to move the cultivator, and during operation the wheels are lifted up.

The productivity of MK-1 when milling the soil to a depth of 20 cm is 0.017 ha / h, and when cultivated to a depth of 10-12 cm - 0.05 ha / h, that is, its use in the most labor-intensive processing operations, soil increases labor productivity compared with manual more than 5 times. Additional devices are supplied to the MK-1 motor cultivator: weeders with L-shaped knives with a wedge-shaped blade; discs that protect against damage during rotary tillage; hiller. Using these devices, it is possible to complete the unit, for example, for the combined processing of potato rows: the weeders are installed instead of the working bodies-rotors, and the protective discs are installed on the shafts of the weeders; the hiller is mounted instead of the doser on the back of the frame. During the operation of the unit, weeder knives loosen the soil, prune weeds and at the same time facilitate the movement of the cultivator, and the hiller on the loosened soil spuds two adjacent beds on one side each in one pass. Such a unit processes 0.14 ha / h, which is 18 times more productive than performing similar works manually.

Overall dimensions of MK-1 - 1300 X 800 X 810 mm, weight 50 kg, it can be freely placed in the trunk or on the roof of the car.

In general, for modifications of all motor-cultivators of the "Mole" type, in addition to the working bodies already mentioned for MK-1, a small plow, a mower, a semitrailer with a carrying capacity of 200 kg, and a water pump are produced. A front attachment has been developed, which forms a motor-carriage when the attachment is connected to the power unit of a motor-cultivator. A sprayer, a house sawmill and other accessories are created in the calculation of the use of this power unit.

Modifications MK-2 and MK-3 have wheel diameter 320 mm, ground clearance 90 mm, track 285 or 600 mm, overall dimensions 1960X800X1170 mm. The MK-2 model has one forward gear, providing a speed of up to 7 km / h, weight 50 kg. The MK-3 model has two forward gears providing travel speeds of 4.7 and 7.1 km / h and two reverse gears (2.8 and 4 km / h), weight 60 kg. This model has an optional pulley mounting option and is equipped with rear and front linkages. With the help of a pulley, you can drive various small-sized machines, including those used in home farming. The rear hitch is hung or attached to it tools associated with the use of tractive effort (plow, hiller, semitrailer, etc.). On the front, implements and machines with active working bodies (a mower, a feed crusher, a pump, and others) are hung and driven through a V-belt transmission.

For higher performance, I suggest installing a 4-stroke Chinese-made LIFAN-160F engine on the MK, with a power of 4 l / s. This increases the power of the MK at low speeds. Now there is no need to increase the engine speed in order to process the soil depth of 20 cm (according to the passport). In addition, due to the power, the processing depth increased 1.5 times and amounted to about 30 cm (before the belt slipped). The engine copes with this task easily.

Another not unimportant plus of this replacement is that the engine starts up in a cold or hot state. Turnovers are automatically maintained at a given level. With more power, gasoline consumption remained approximately the same as that of the standard engine, moreover, now there is no need to add oil to gasoline (4-stroke engine).

Installing a new engine does not involve much effort and rework. The engine mounts fit into place. The pulley is taken from the old engine, slightly reaming the inner hole and keyway.

Having pretty much worn out with the old engine, now with the new one, completely different emotions when working with a motor-cultivator!

Buying a cultivator greatly simplifies the process of performing summer cottage work of a various nature. It's not a secret for anyone that such equipment can break down and still breaks down. So that the summer resident does not have to buy a new unit, he must understand how to independently repair the cultivator. Let's discuss this issue later in this article.

All working components of cultivators during their operation are subject to rather heavy loads. For this reason, they need regular inspection and repair. First you need to configure the ignition and fuel pump systems of the unit. Indeed, in the winter period of time, he was idle "without work", which can cause problems with starting the engine. It is also worth checking the transmission. Remember, negligence at this stage of work can lead to serious breakdowns and the need to overhaul the cultivators.

To do it yourself, you need to mature at the root of the issue. That is, to understand the cause of the malfunction, and in which unit of the apparatus it arose.

Conventionally, all breakdowns of equipment of this type can be divided into two groups:

breakdown of the engine of the apparatus;
breakdown of other parts of the equipment.

According to the reviews of experienced summer residents who use Texas or Mole cultivators on their plots, problems of the first group are more common. How to carry out repairs yourself will become clear if you read this article to the end.

To repair the cultivator engine, as in the following photo, you need to determine the root cause of the problem. There may be several: let's discuss each option.

In cases where the engine of the apparatus does not start at all, perform the following sequence of actions:

Turn on the ignition;
Check the gasoline level;
Open the fuel cock;
Check carefully the air damper of the Texas walk-behind tractor carburetor: it should be tightly closed if you start a cold engine;

The motor of the Mole cultivator does not give power due to such problems:

The air filter is clogged: repairing the cultivator with your own hands will be reduced to cleaning it;
The muffler is clogged: it should be disassembled and washed;
The carburetor of the Mole cultivator is dirty: it needs to be dismantled, cleaned and adjusted.

You will need to repair the cultivator gearbox if its operation is accompanied by increased noise. A similar phenomenon is typical in the case of a lack of oil. Add it to the gearbox of the device, or better, replace it altogether.

Also, noise can arise due to the "loosening" of the fasteners of the nodes: inspect and fix them with your own hands.

In addition, summer residents may face the problem of oil leakage from the gearbox. This can occur due to wear or improper installation of the seals of the bearing units, with poorly fixed covers and deformation of their accompanying gaskets. Replacement and subsequent high-quality installation of oil seals, self-replacement of gaskets and fixing of cover fasteners, as well as high-quality cleaning of the breather will help to eliminate such a leak.

Do not forget to timely change those parts of the Texas gearbox that are more susceptible to wear and tear during the operation of equipment of this kind.

Excessive vibration of the device during its operation is typical for those cases when the summer resident has poorly performed the adjustment of the attachments of the attachments. Stop the equipment the minute vibration is noticed and adjust the attachment parts accordingly. If the fasteners are worn out, they will need to be replaced with new ones.

This article described the most common problems that summer residents may face when preparing a cultivator for the new season. You can eliminate them with your own hands without much difficulty, but you need to approach this task responsibly. The video in this article will once again tell you in detail about the features of the repair of cultivators.
