Design features
The device of the Mole walk-behind tractor is determined by the presence of such interconnected nodes:
- Frame - consists of two connected semi-frames. The structure is bolted to the gearbox.
- Internal combustion engine - attached to the frame and connected to the input shaft of the gearbox by means of a V-belt transmission.
- The attachment bracket is located at the rear of the unit.
- Cutters - put on the output shafts of the gearbox.
- Transport wheels.
- Fuel tank (located at the top of the unit).
- Reducer.
- Controls - located on the handles of the cultivator.
The motor for the Mole walk-behind tractor from the manufacturer has forced cooling and is a two-stroke single-cylinder engine. A non-removable starter is located on it, the start of which is carried out by means of a sharp tension on the cable.
The engine for the Mole walk-behind tractor has a working volume of 60 cm3 and is filled with A-76 gasoline, to which autol (M-8B1) motor oil is added in the proportion specified in the instructions for this model (1: 20-1: 25). The factory complete set includes spark plugs "A-17B", for stable operation and prevention of carbon deposits, it is recommended to replace with a spark plug "A-11".

Some models of the Mole walk-behind tractor are equipped with Chinese four-stroke engines. The cultivator's "native" engine lacks power, which affects the performance of the mechanism. The design of the frame allows you to replace the engine with a more suitable one, which eliminates problems in the future.
The following models are the best options for such substitution:
- LIFAN 168FB with a shaft diameter of 20 mm and a power of 6.5 hp;
- Patriot;
- Honda GC 135;
- Sadko DE-220;
- Forza 160F.
When installing the motor, it is important not to exceed the permitted power. If you take a motor over 6.5 liters
with. the gearbox often begins to break down due to excessive loads.
The size belt for walk-behind tractor The mole is determined depending on the model. There are only three sizes to fit the models of this brand:
- А13 * 900 - devices with an imported four-stroke engine;
- А13 * 700 - suitable for the first modifications with a "native" motor;
- А13 * 750 - fits most models with a pulley diameter of 150 mm.
The value "A13" means the profile of the belt, and the numbers 900, 750, 700 are its length.

Standard cutters for the Mole walk-behind tractor have a diameter of 330 mm. They are mounted on the power take-off shaft. The choice of a cutter model depends on the type of soil to be treated. So, for medium and light soils, 1-2 pairs are used, and for virgin lands it will take three.
Before cultivating the soil, the transport wheels must be lifted and the coulter must be mounted on the trailed shackle. It is he who will regulate the depth of soil cultivation. If the soil to be cultivated is dense and heavy, it is better to use crow's feet cutters, and for soils with a lower hardness, cutters with four or three lobes are suitable.
Motor cultivator device
The Mole motor-cultivator, as well as the Cayman, Patriot, Texas, Foreman, Crossser, Viking, Forza walk-behind tractors, is quite popular in the post-Soviet space, which is explained by the simplicity of its design and rather good performance indicators.
There is absolutely nothing superfluous in the configuration of this walk-behind tractor, but its device is made in such a way that it is able to cope with basic agricultural work - digging beds, cultivating soil, etc.
In addition, the design of the main working units allows it to withstand rather long-term loads, ensuring stable operation for many years.

The very design of the Mole walk-behind tractor consists of the following components:
- The frame structure, consisting of two half frames, is bolted to the gearbox.
- Tubular handles, as well as a special bracket for attaching additional attachments, located at the back of the structure.
- The main controls are located on the handles - adjusting the engine speed, as well as the clutch.
- Tillers can be put on the output shafts of the gearbox, as well as wheels that allow you to use the walk-behind tractor with a plow, or for transporting various loads.
- On the frame structure there is a motor for the Mole walk-behind tractor, which is connected to the input shaft of the gearbox through a V-belt transmission.
- In addition, the design has built-in wheels that allow the unit to move freely. When starting work with a walk-behind tractor, these wheels must be removed from the structure, or raised and fixed in the desired position.
As we can see, the device is quite simple and does not include unnecessary frills. In principle, everything that is needed for high-quality work on the ground - all this is in the design of this unit and in the Sadko, Don, Hooter, Profi, Plowman, Champion walk-behind tractors.
Its volume is about 60 cm3, with a power of 2.6 hp. and 6000 rpm. It is started using a conventional cable, according to the principle of a chainsaw plant.
You need to fill it with a special mixture consisting of gasoline and engine oil. These characteristics are rather modest, so many people want to change it to more powerful models.
Replacing the factory engine can be done independently, because the design of the Mole, as mentioned above, does not present a certain complexity in its understanding. Most often, they resort to replacing them with 4-stroke versions of engines, because they have higher performance than 2-stroke ones.
Of course, there are some modifications, such as a Mole walk-behind tractor with a 4-stroke Honda engine, but its cost will be significantly higher than that of a standard Mole. Therefore, we are considering the "worst" option, when we have a walk-behind tractor with the most standard factory engine, with a capacity of no more than 3 hp.
