Cultivator Tarpan
LLC "Tarpan" - a subsidiary of the production association "Tulamashzavod", designs, produces and sells mini-agricultural machinery for various purposes.
Cultivators "Tarpan" are affordable, well-assembled, equipped with reliable power plants supplied by companies from the USA, Japan and China.
The principle of operation and description of the Tarpan motor-cultivator
The torque from the gas engine through the clutch mechanism and the worm gear is transmitted to the shaft of the working cutters, which rotate, loosen the soil layer and move the unit along the strip.
The product belongs to the middle class of cultivators, it processes any soil density, including heavy ones, on plots up to 20 acres.
Sufficient power of the power plant, the ability to process a working strip up to 1 m wide, a set of additional attachments make the device a productive and multifunctional assistant to the owner of the land plot. 
For convenient transportation, the machine is quickly divided into blocks:
- Energy, which includes:
- engine;
- clutch mechanism;
- docking station;
- steering.
- Executive, consisting of:
- worm gear;
- right and left rotary cultivators (working cutters);
- loosening depth regulator;
- mounting bracket;
- protective casing.
Most models use four-stroke, vertical-crankshaft petrol engines from B&S or Honda. Units with the Chinese Champion engine are offered for a lower cost.
The clutch device is assembled according to the friction scheme, automatic type. The mechanism smoothly engages to transfer torque with increasing engine speed.

The invention relates to the field of mechanical engineering, more specifically to small-sized agricultural machinery, but can be used in other fields of technology, where a connection of rotating shafts is required. The automatic centrifugal clutch of the motor cultivator includes two brake pads fixed through bearings on the motor shaft, contacting with the transmission during shaft rotation and tightened together by springs fixed in holes that are located symmetrically relative to the engine shaft. The novelty is that each brake pad is provided with at least one additional hole with the ability to fix the springs in any of the holes, and the additional holes are located in such a way that one position of the spring is perpendicular to the line connecting the bearing and the outermost contact point of the brake shoe. The technical result is to increase the efficiency of the clutch and the possibility of using it with various types of engines and actuators. 6 ill.
The invention relates to the field of agricultural machinery, in particular small-sized, designed for processing small-contour areas by milling and other work on the automation of manual labor.
Known motor-cultivator "Tarpan-03", which has an automatic centrifugal clutch, including fixed through bearings on the engine shaft brake pads, tightened by springs. The pads are in contact with the transmission when the shaft rotates, transmitting torque from the engine. The springs are fixed in holes located symmetrically to the motor shaft. Tillage cutters are installed on the output shaft (000 "Tarpan", Motor-cultivator "Tarpan", model TMZ - MK - 03, Operation manual, 093 300 000 OM. P.4, 15).
The disadvantages of the known device are the lack of adjustment of the transmitted torque depending on the wear of the pads and the stretching of the springs; the inability to replace engines with different numbers of initial revolutions on a motor-cultivator; the impossibility of connecting attachments or tools to the clutch, for the operation of which a torque of a different magnitude is needed; a small spring resource due to the presence of an additional bending moment.
The task of the proposed technical solution is to adapt the cultivator to different types of engines and different actuators.
The task is achieved by the fact that the automatic centrifugal clutch of the cultivator, which includes brake pads fixed through bearings on the motor shaft, contacting with the transmission during shaft rotation and tightened by springs fixed in holes that are located symmetrically relative to the engine shaft, each brake shoe is equipped with at least at least one additional hole with the ability to fix the springs in any of the holes, and the additional holes are located in such a way that one position of the spring is perpendicular to the line connecting the bearing and the outermost contact point of the brake shoe.
Thus, this will increase the clutch life by adjusting the transmitted torque depending on the wear of the brake pads and the stretching of the springs; apply and replace one with another engines with different numbers of initial revolutions; connect attachments to the engine for performing various agricultural operations by setting the springs of four different clutch actuation points; increase the service life due to the installation of axial loading and the elimination of the additional bending moment of the springs.
The claimed technical solution is illustrated by drawings, where figure 1 shows a motor cultivator complete with cutters; figure 2 shows a motor-cultivator complete with a plow and propellers (arrows show the direction of movement of cutters and propellers); Figures 3, 4, 5 and 6 show a section A-A in the region of the centrifugal clutch - these figures show four options for installing the springs.
A motor-cultivator consists of an engine 1 (Fig. 1, 2), a transmission 2 (Fig. 3-6), on the executive shaft 3 of which there are installed tillage cutters 4 (Fig. 1) or propellers 5 (Fig. 2). Complete with propellers 5, a plow 7 is attached to the body 6 of the transmission 2. The engine 1 and the body 6 of the transmission are interconnected with cap screws 8.
The automatic centrifugal clutch of the cultivator includes brake pads, consisting of friction linings 9 and pads 10. The pads 10 can be rotated on bearings 11 installed through a leash 12 on the motor shaft 13. A gap is made between the transmission 2 and the friction linings 9. The pads 10 are pulled together by springs 14 installed in holes 15 (Fig. 5) or in additional holes 16 located closer to the engine shaft (Fig. 3), or alternately in the main and additional holes (Figs. 4, 6). The choice of spring installation method depends on the torque transmitted by the clutch. The moments tightening the brake pads with springs 14 are different. Figures 3, 5 show different arms of application of forces relative to the bearings 11. In the variants shown in Figs. 4 and 6, the pre-tension of the springs is higher than in the variants in Figs. 3 and 5. The axes of the springs 14 shown in Fig. 4 are perpendicular the line connecting the bearing axles 11 and the contact point 17 farthest from the bearing on the friction lining 9. Instead of transmission 2, another actuator can be connected to the engine 1, for the operation of which a torque of a different magnitude is needed: a lawn mower, a trolley, a feed crusher, a water pump, etc. .d.
The device works as follows. When turned on, the engine 1 rotates the shaft 13 through the leash 12 brake pads. Friction linings 9 do not come into contact with the transmission, since the moment pulling together the pads 10 is higher than the centrifugal force generated by the engine during rotation. If the engine has a high initial number of revolutions, then in order to prevent spontaneous engagement of the transmission, the clutch torque of the pads 10 is increased by setting the springs 14 to the position shown in Fig. 6. If the engine 1 breaks down, it can be replaced by an engine with a different initial speed, while moving the springs 14 to a different position. The operator increases the number of revolutions of the engine 1, while the torque pulling the pads 10 becomes lower than the centrifugal force from the rotation of the engine 1. The pads 10 rotate in the bearings 11 and the friction linings 9 contact the transmission 2, transmitting the torque to the tillage cutters 4 or to the propellers 5 or to another executive body. The greatest moment is transmitted by springs 14 with the smallest clutch moment of the brake pads. The greatest force of the pads 10 is transmitted at the point 17 of contact of the friction lining 9, since this point is farthest from the bearing 11. After the service life is reached, the section in the region of point 17 wears out more, the stroke of the spring 14 increases and the transmitting moment decreases. In this case, the springs 14 are moved to the position shown in Fig. 3, thereby increasing the transmitting moment. If the springs are stretched during operation, the transmitting moment decreases, the springs are rearranged to the position shown in Figs. 4, 6. During the operation of the springs fixed as shown in Fig. 6, their service life increases due to the elimination of additional bending moment (spring located perpendicular to the shoulder). To install another actuator, unscrew and raise the swing bolts 8, remove the transmission 1, install another unit, lower and tighten the swing bolts 8.
Automatic centrifugal clutch of a motor-cultivator, which includes two brake pads fixed through bearings on the motor shaft, contacting with the transmission when the shaft rotates and tightened together by springs fixed in holes that are located symmetrically relative to the engine shaft, characterized in that each brake shoe is equipped with at least one additional hole with the ability to fix the springs in any of the holes, and the additional holes are located in such a way that one position of the spring is perpendicular to the line connecting the bearing and the outermost contact point of the brake shoe.
10366 08.10.2019 7 minutesIs not only a breed of wild horse, which no longer exists on our land. So called domestic cultivatorsthat are used to cultivate land up to five to twenty acres.
They are popular with users due to their reliability and powerful motors from American and European manufacturers.
About the manufacturer
This model was invented by Tula engineers in 1991, as a simple and reliable replacement for the "Rus" walk-behind tractor, which was produced by "Tulamashzavod".
At first "Tarpan" was unprofitable, it was not in great demand, but after it was improved and equipped with a productive motor company "Briggs & Stratton" things went much better. Since 97, the cultivators have been launched into mass production.
Today it is manufactured by the specialized company "Tarpan", which is a subsidiary of "Tulamashzavod", which is located in the historical center - Frolovskaya Sloboda, which is famous for its specialists.
On the land that belongs to a legal entity today, in 79 of the nineteenth century, the Baytsurovsky plant was built, which produced various cast iron and copper products.
Tulamashzavod is a well-known company that specializes in mechanical engineering.
The enterprise includes production facilities that are equipped with new equipment and leading technologies. You can find all the necessary information on the official website tar-pan.ru.
The production includes: procurement shops, electroplating and high temperature processing, production of tools, parts, wood processing.
Along with classical equipment, automatic and semi-automatic devices are used, which allow you to run the program in an interactive mode. This ensures a high technological production flexibility.
To shorten the preparation time is often used end-to-end automatic design of elements and equipment (from external indicators to the creation of control programs for machine tools).

Popular models
The first motor-cultivator from the Tarpan series with a 6.2 hp two-stroke motor. was released from the assembly line in 93. He immediately established himself on the market on the positive side, but due to some shortcomings in the production nature, it was not so popular among farmers.
03
Thanks to the work of engineers, in a few years on the domestic market presented the model "Tarpan-03"... To this day, it does not lose its leading position in the Russian market - up to a thousand of such cultivators are bought every day.
The plant engineers have supplemented the model with various attachments that can be used regardless of the year: for winter you can use a rotary snow blower, while its coverage will be 75 cm.It throws snow up to 5 meters, you can also purchase an ice breaker to clear the path ...
Regardless of the season with Tarpan cultivators, you can carry out all gardening work using a plow, a rotary cutter (included), a hiller, a flat cutter, a rake to chop and level the soil, collect for weeds and other mounted equipment.
The cultivator can be used as a lawn mower, and in the fall you can dig up root crops with it, and prepare the soil for winter.
The service life of the motor is 1000 hours. The centrifugal clutch machine allows you to disassemble the model into several devices, which can be easily transported and stored.
Thanks to the worm gearbox, you can abandon unreliable belt and chain drives that are installed on the walk-behind tractor.

Manual
It is important not to use the unit at full capacity for several days after purchase - it must be remembered that the device must be run-in for the first 24 hours. Therefore, it is better to process the same bed in several stages, and each time increase the depth of processing.
Start
Before launch is check the oil level, serviceability of the engine, is the power unit securely fixed with another unit that performs an additional function.
It is forbidden to start the engine when the control lever is clamped (the position of the engine speed governor is "fast"), because the clutch of the device works automatically when the engine reaches the required speed, which is more than idle speed.
Soil treatment
It is necessary to stand near the steering wheel and hold the handle firmly. Do not press hard on the lever, slightly increase the number of engine revolutions.
When the motor reaches the required speed, the centrifugal clutch will automatically engage and the gearbox shaft will begin to turn.
At this time, the device will begin to move. Deep soil processing with milling cutters determined by the position of the depth regulator, which can change when rearranging it in the bracket along the holes that are in the regulator.
Turn off device
To do this, lower the control lever. It will automatically return to its original idle position as a result of the return spring. Then pull it down until it stops and the motor stops running.
Malfunctions and repairs
"Tarpan" cultivator, operating instructions indicate some of the causes of breakdowns. Motor impossible to run or is difficult. This may be due to a knocked-down setting of the engine speed regulator, or fuel is not supplied to the carburetor.
To eliminate this malfunction, you need:
- Check for fuel in the tank.
- Check spark plug gap.
- If necessary, remove carbon deposits from the spark plug or replace it.
- Check the correct operation of the carburetor.
The motor may also become warm.
It starts to overheat because the cooling system and air filter are clogged.
To keep the engine running at normal temperature, the cooling system and air filter must be cleaned or replaced.
The engine does not run at maximum rpm. This is often due to the fact that air filters clogged and must be replaced. To eliminate this malfunction, you must clean or replace the filter.
Malfunctions often happen due to the fault of the operator due to irrational use of equipment, therefore, before starting work, be sure to read the instructions. If you have not saved the original, you can find it on the Internet, in one of the search engines write: "Tarpan cultivator operating manual."
The Tarpan model range is constantly updated and improved in terms of its technical characteristics.
Conclusion
The main feature of cultivators is quite efficient motor, in comparison with other models of this kind. The only drawback of the lineup: there is no reverse gear.
People who grow crops on the site almost always use.
Motor-cultivator Tarpan can be attributed to the middle class, single-operation, having one speed. It is equipped with a B&S 6 hp engine. Adjustable cutter grip 35/70/100 cm. Also fitted with worm gear and automatic centrifugal clutch. Walk-behind tractor weight 45 kg. It does not provide reverse gear and power take-off.
Is it worth buying a Tarpan motor cultivator
For rolling the walk-behind tractor, two wheels are installed. And in order to adjust the depth of the cutter, a coulter is installed. The walk-behind tractor itself can be easily disassembled into two parts. The casters and handles are removable. This makes it easy to fit into the trunk of a car.
The main feature of Tarpan is a rather powerful engine, in comparison with other cultivators of this class. Unfortunately, the designers did not provide for a reverse gear, which is a big disadvantage. The worm gear of the gearbox was installed in a fairly robust housing.
Unfortunately, it does not have a reverse due to the large gear ratio. When processing heavily planted areas, it is often necessary to pull out the cultivator in reverse. This usually occurs in places where a reversal is not possible.
In this case, the cutter does not turn back, it skips and unfolds what has just been loosened. It is for this reason that gearboxes with gears or with chain drives are installed in modern cultivators. If a worm gear is installed, then only with reverse gear.
Therefore, Tarpan is very convenient for the owners of open gardens, and for those who will prepare the soil for further processing and sowing. In this case, there is no great need for the convenience of controlling the walk-behind tractor in reverse gear.
Clutch and speed of the Tarpan motor-cultivator
The next design features of the cultivator are an automatic centrifugal clutch and a split "leg". This allows it to be disassembled into two parts and folded into the trunk of the car, which is a definite plus. On the other hand, thanks to this feature, the clutch "often flies out" when working with a hiller, plow, digger. If you use an automatic clutch, it has a large response inertia, which is unsafe.
To turn on the speed, to start the cutter, you need to turn the throttle lever. This will increase the RPM, after which the cutter begins to rotate. If an urgent need to stop the cutter, the operator must remove the gas. This will not immediately turn off the cutter, and it will continue to run for a while. In this case, you need to use the "Stop" button.
Also in the structure of the cultivator, a new design of the steering rod is used, which allows it to be turned 360 degrees and to adjust the angle of inclination. This allows the operator to walk close to the cultivator and not on cut furrows or loosened soil.
If you install additional equipment on the Tarpan motor-cultivator, then it will be able to weed, huddle, harrow, loosen, mill, etc.
Motor-cultivator Tarpan reviews
Vladimir, a resident of Belgorod, uses the Tarpan Motor-Cultivator at his summer cottage:
I have been using Tarpan for 9 years. The positive overall experience is primarily due to the engine. Advantages of a motor-cultivator: always starts from a half-barrel; since there is a four-stroke engine, there is no need to oil the oil, just poured gasoline and change it a few times a year; easily fits into the trunk of any passenger car, because it can be disassembled into two halves. Disadvantages of Tarpan: the gas is made very inconveniently - under the thumb of the right hand. He gets tired quickly.
Feedback from Sergey, a resident of Omsk, uses the Tarpan Moto-cultivator on his site:
With its light weight (48 kg) and "monstrous" excess power, it is difficult to take the virgin soil. If you first use a tractor plow that breaks the roots, the lumps will be dealt with quickly and easily. Due to the peculiarity of the design, the reverse is not installed. But with its light weight, it can be deployed manually without any problems. I saw how a cart was dragged with a converted Tarpan. The plow does not pull because it is lightweight. And at the same time, it perfectly cuts the beds with a hiller on cutters. Excellent material from which the cutters were made.
Review of Andrey Ivanovich, a resident of Rostov, uses the Tarpan motor-cultivator in a greenhouse:
I sharpened them once after buying them, and never touched them again. Basically I use a hiller and cutters - I will cut the beds, plow and that's it. Needs negligible gasoline: for an hour of work, a 1.5 liter tank is enough. The first time I took off the cutter cover, because it only interfered, because a lot of grass is wound around the cutters. I also hung a 20 kg weight in front, thanks to which the virgin soil was taken much better. But she dangled in front and rocked the cultivator.
In general, if used for summer cottage work with a minimum of settings and hemorrhoids, this is quite a convenient thing. Also, do not forget that the first task of the cultivator is to loosen the soil, which he does just fine. Therefore, only cutters are included with it. 
Feedback from Roman Viktorovich, a resident of Kharkov, uses the Tarpan Motor-Cultivator in the country:
I have been working with Tarpan since 2004. Very satisfied. If, when working on heavy ground, he begins to jump and tries to run away, then first you need to remove and sharpen the knives. It is advisable to attach a load. Made a load of lead (melted old batteries). The result is a weight of 13 kg, has a compact volume and allows you to work perfectly. Also can be made in the form of multiple plates to adjust the weight. I use the load for digging trenches, virgin lands and primary plowing. Then I shoot and it works great.
Alexey, a resident of Kharkov, uses Tarpan on his personal plot:
Recently acquired by Tarpan. Yesterday I went through the garden with cutters. Feelings: the engine runs vibration-free and quiet; the cultivator is a little light, sometimes bounces; perfectly cultivated the second time when turned the horns, no trace left. Processed seven acres. It took two hours and three liters of gasoline.
Vladimir Ivanovich, a resident of Belgorod, uses a motor-cultivator in the country:
The load on the back and arms is acceptable. In addition to cutters, I did not test attachments. The cutters have to be cleaned because they wind up the roots a lot. But I think that this is a plus, since weeds are removed from the garden. If the cutters are sharp, they will chop the roots, after which weeds will multiply.
Motor-cultivator Tarpan video compilation
Plow for motor-cultivator Tarpan
For its manufacture of the plow for the Tarpan motor-cultivator, high-strength special steel was used to withstand heavy loads. Its purpose is to plow the soil complete with lugs, thanks to which the required tractive effort is created.
The use of a plow is possible for initial tillage. To loosen large clods of soil, cultivation is necessary.
