Dear gardeners!
On the eve of the next summer season, we are all faced with the need to cultivate the soil. Most use mini-agricultural equipment for this, namely a cultivator or walk-behind tractor. Moreover, the Soviet cultivator "Mole" is known to everyone.
As a rule, this unit was massively purchased 10-15 years ago and served faithfully for a long time. Serially, this cultivator was equipped with a 2.6 hp two-stroke engine, modifications were produced with a rear speed and only with a front one.
At the moment, for most gardeners, the Krot cultivator has served its time and requires a thorough repair. As a rule, the quality of modern spare parts leaves much to be desired, and native parts have worn out. After replacing one part, another breaks.
If the gearbox is working, then it is enough to replace the engine on the cultivator. Now in stores there is a large selection of engines from different manufacturers. To work in the country, feel free to choose engines from well-known Chinese manufacturers, such as Champion, Forza, Lifan etc. The main thing is to contact trusted sellers. Before buying, be sure to require a pre-sale check, that is, it must be filled with oil, gasoline and started. Fuel is paid by the buyer.
For the Mole cultivator, a 4 hp engine is enough, you can also put 5.5 hp, 6.5 hp engines.
Important! A flooded engine must not be turned over.
1.Pulley
The pulley must be selected depending on the diameter of the shaft on the new engine. As a rule, it is 18 mm, 19 mm, 20 mm.
2.Oil
The new engine is four-stroke, so you need to buy special oil for 4-stroke garden equipment. Automobile is not allowed. Do not forget that oil is poured separately, gasoline - separately (AI-92). The first oil change is done after 5 hours. Therefore, two bottles of oil are usually purchased (one of which is filled during a pre-sale check).
3. Bolts, washers, nuts.
You will need bolts to mount the motor to the frame, the pulley to the motor.
4. Gas cable- installed on request.
Now let's move on to the installation of the engine on the Krot cultivator.
Depending on the modification of the cultivator, the new engine will either perfectly fit the frame, or two additional holes will need to be drilled.
Step 1
It is necessary to install the pulley on the shaft on the engine, insert the key, adjust the distance from the engine to the pulley with washers, fasten the pulley with a bolt and washer.
Step 2
We try on the engine on the frame. At the same time, we put the belt on the engine pulley, gearbox pulley, tension roller.
In our case, the holes did not match, we had to drill new ones.
Step 3
We install the engine on the frame, fasten everything with bolts.
Step 4
Be sure to make wings for the cultivator, otherwise all the dust during cultivation will get into the engine, the air filter will become dirty very quickly.
Step 5
Let's get to work. In no case do not work at idle! Maximum - a couple of minutes we warm up the engine and get to work. The only thing is that at first we work in a sparing mode: after 10-15 minutes we let it cool. The first oil change is after 5 hours.
Small-scale mechanization is gradually entering the agricultural industry, which greatly simplifies the process of carrying out land works.
Not the last role in this is played by walk-behind tractors of various manufacturers, distinguished by their compactness and relatively high power, depending on the type of engine used. In our country, domestic units are traditionally popular, familiar to many since Soviet times.
In particular, we are talking about the Mole walk-behind tractor, which is the first model, the serial production of which was launched in the USSR.
However, many are not happy with the factory engine that comes with the kit, wanting to replace it with a more powerful one.
This does not at all mean the poor performance of the "native" motor, but some want to install a more powerful unit. Consider this issue from all sides, taking into account the technical features of the complete set of the Mole motoblock, and also find out which engine can be put on it.
Motor cultivator device
As for the factory engine of the Mole walk-behind tractor, its device is a 2-stroke engine with one cylinder and air cooling.
Its volume is about 60 cm3, with a power of 2.6 hp. and 6000 rpm. It is launched using a conventional cable, according to the principle of chainsaw plant.
It needs to be filled with a special mixture consisting of gasoline and engine oil. These characteristics are quite modest, so many want to change it to more powerful models.
Replacement of the factory engine can be done independently, because the construction of Mole, as mentioned above, does not present a certain difficulty in its understanding. Most often, they resort to replacing with 4-stroke versions of engines, because they have higher performance characteristics than 2-stroke ones.
Of course, there are also some modifications, such as the Mole walk-behind tractor with a 4-stroke Honda engine, but its cost will be significantly higher than that of the standard Mole. Therefore, we are considering the “worst” option, when we have a walk-behind tractor with the most standard factory engine, no more than 3 hp.
What kind of electric motor can be put on the Mole cultivator
frame design walk-behind tractor Mole allows you to install other engines on it manufactured in various factories. At the same time, the alteration of the frame will be minimal, consisting in a few simple manipulations.
Lifan
Many note that the Lifan 168FB engine, whose power is 6.5 hp, will be the best choice for installation on a Mole. This is explained by the fact that spare parts for it are quite cheap and affordable, so they can be easily found in any specialized store.
As practice shows, you need to take it with a 20 mm pulley shaft (there is another type of 19 mm engine). It is also important to have an oil bath at the air filter, because such a device is used specifically for areas where there is increased dustiness.
Motor Patriot
Besides, you can install a Patriot electric motor for the mole motoblock, the cost of which is within 6 thousand rubles. The only thing is that you need to take care of the electricity in your area so that the device can work stably.
Sadko
A good option is obtained by installing a SadkoDE-220 engine on this walk-behind tractor, whose power is about 4.2 hp. The shaft diameter is 19 mm, it is started with a cord.
One of the most labor-intensive activities in agriculture is grain harvesting. Combine harvester - excellent quality for decades.
The snow sheet is far from the best surface for cars, so in snowy areas it is necessary to use other modes of transport, such as a snowmobile. all information about the wonderful snowmobile Varyag 550.
The mole cultivator has earned the trust of customers due to its reliability and simplicity of design. However, many farmers are trying in every possible way to improve the unit, improve its technical characteristics and performance.
To do this, you can purchase and install a new engine for the Krot motor cultivator - it will make the unit more powerful, which will positively affect its performance and capabilities.
Mole cultivator device
There are practically no extra parts in the configuration of the domestic unit, however, the design of the cultivator is made in such a way that the owner can use it for a variety of economic purposes. Due to the reliability of the main components, the equipment is able to withstand prolonged loads. The design of the unit consists of the following elements:
- The frame, which is connected from two half-frames, is attached to the gearbox housing with bolts;
- Tubular handle and bracket for the operation of attachments;
- control levers;
- Pneumatic wheels that are mounted on the output shafts of the gearbox;
- 2-stroke single-cylinder engine with an air-cooling system attached to the frame - connected to the reduction shaft through a V-belt drive.
Among all the elements, the engine deserves special attention - its volume is approximately 60 cm3, torque - 6000 rpm, and power - 2.6 liters. With. The engine runs on a mixture of engine oil and gasoline.
It is not difficult to guess that the low power of the standard engine is pushing farmers to replace it. This operation is quite simple, but you will need to choose the right engine for the Mole cultivator. Below we will figure out which motor is suitable for mounting on a domestic unit.
What motors are suitable for installation on the Krot cultivator?
Among the suitable engines for most Mole units, the following models stand out:
Motor Lifan 168 FB
Power 6.5 liters. With. with 2cm pulley shaft. Some configurations have a shaft, 1.9 cm long.
The motor air filter should be equipped with an oil bath, which helps to reduce the load on the motor in dusty areas.
Imported motor Sadko DE-220, 4.2 l. With.
The shaft diameter of this motor is 1.9 cm, and the motor is started with a cord.
Patriot electric motor, 7 hp. With.
It is also quite reliable, however, an uninterruptible power supply should be located near the site.
Each of these motors fit well into the design of the cultivator, and the installation of the device will require a minimum of frame alterations.
Self-replacement of the engine - instructions and nuances
To change a standard motor to an imported one, you need to follow the instructions. The correct algorithm looks like this:
- First, unscrew the factory motor mount, remove the gas and mute wires;
- Remove the engine from the frame;
- Attach a new motor and mark on the frame the places where you need to drill holes;
- Install a new motor, put a belt on it and move it along the frame until the maximum tension of the belt. Make sure that the motor pulley and the gearbox pulley are in the same plane;
- Connect the motor to the frame with bolts.
- Connect transmission channels.
Before work, the finished structure should be "driven" at idle.
During the break-in, you will have to burn at least two gas tanks of fuel, however, such “victims” are necessary for the new engine to work properly.
