Installing a Lifan engine on a tiller mole

Motor cultivator device

The Mole motor-cultivator, like Tillery Cayman, Patriot, Texas, Foreman, Krosser, Viking, Forza is quite popular in the post-Soviet space, which is explained by the simplicity of its design and rather good performance.

There is absolutely nothing superfluous in the configuration of this tiller, but its device is made in such a way that it is able to cope with the main agricultural work. digging beds, cultivating the soil, etc.

In addition, the design of the main working units allows it to withstand fairly long-term loads, ensuring stable operation for many years.

For more information about the tiller Mole, see

The very design of the Tiller Mole consists of the following components:

  • Frame construction, consisting of two half frames, 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 tiller with a plow, or for transporting various loads.
  • On the frame structure there is a motor for the Tiller Mole, 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 the tiller, 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 tillers Sadko, Don, Huter, Profi, Plowman, Champion.

As for the factory engine of the Tiller Mole, 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 starts with a regular 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.

Of course, there are some modifications, such as the tiller Mole 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 tiller with the most standard factory engine, with a capacity of no more than 3 hp.

Cultivator device Mole

There are practically no unnecessary 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 unit design consists of the following elements:

  • The frame, which is connected from two semi-frames, is attached to the gearbox housing with bolts;
  • Tubular handle and bracket for the operation of attachments;
  • Control levers;
  • Pneumatic wheels, which are mounted on the output shafts of the gearbox;
  • 2-stroke, single-cylinder air-cooled motor, attached to the frame. connected to the gear shaft by means of a V-belt drive.

Among all the elements, the engine deserves special attention. its volume is approximately 60 cm3, the torque is 6000 rpm, and the power is 2.6 liters. from. The engine runs on a mixture of engine oil and gasoline.

It is not difficult to guess that the low power of the standard motor pushes farmers to replace it. It is quite simple to perform this operation, but you will need to choose the right engine for the Mole cultivator. Below we will figure out which motor is suitable for installation on a domestic unit.

Tiller device

Tiller Mole is a frame structure divided into two semi-frames. At the top are the pipe-type handles and an attachment bracket located at the rear. The controls are located on the handles: the clutch and the speed switch. Some models also have a reverse switch.

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

Lifan 125 Semi Automatic Unboxing and Install

The clutch of the minitractor is turned off and is switched with a handle like on a moped. Engaging the clutch provides tension on the belt for torque transmission without slipping.

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

The tiller loosens the soil more thoroughly and mixes the fertilizer in comparison with the plow. Shows good performance on heavy soils and virgin soil.

Tiller Mole moves freely on built-in wheels. Before starting work, they are removed or raised, fixing in the desired position. Do not give full load during the first 15 hours of operation. At this time, the parts are running in. At a “bump” pace of use immediately after purchase, the performance of the motor decreases.

Which engine is suitable for Tiller Mole

The “weak link” of the Mole tiller is the engine, which lacks performance, and it starts badly. The owners of the unit are trying to solve this problem on their own.
