Do-it-yourself tarpan cultivator repair

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. Worm gearbox and automatic centrifugal clutch are also installed. The weight of the walk-behind tractor is 45 kg. It does not provide reverse gear and power take-off.

Two wheels are installed for rolling the walk-behind tractor. And in order to regulate 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 stroke due to the large gear ratio. When processing heavily planted areas, it is quite 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 toothed wheels 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.

The following 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, due 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 it is necessary to stop the cutter urgently, 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 motor-cultivator, a new design of the steering bar 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.

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: it always starts from a half-turn; 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 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 Motor-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 will break 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. Needed is negligible gasoline: a 1.5-liter tank is enough for an hour of operation. The first time I took off the cutter cover, because it only got in the way, 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, first of all, the 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 at the dacha:

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 several 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. Feeling: the engine runs vibration-free and quiet; the cultivator is a little light, sometimes it jumps; 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 milling 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, it will chop up the roots, after which weeds will multiply.

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 with a set of lugs, thanks to which the required tractive effort is created.

The use of a plow is possible for the initial tillage. To loosen large clods of soil, cultivation is necessary.

Motoblock Tarpan is an agricultural unit that is in great demand among farmers in Russia and the CIS countries. This agricultural technique is produced at Tulamash-Tarpan LLC - one of 20 subsidiaries of the largest production holding Tulamashzavod.

Tulamash-Tarpan LLC has been developing and manufacturing equipment for the agro-industrial industry for a long time.

Motoblocks and motor-cultivators of the Tarpan series are the best Russian motor vehicles that differ from other models in excellent build quality, ease of use, ease of operation, reliability and high technical characteristics.

This review will focus on the series of domestic Tarpan walk-behind tractors, their structure, characteristics, maintenance and proper operation.

Tarpan TMZ-MK-03 is considered the base model, launched in 1997.

Motor-cultivator Tarpan MK-03 is a multifunctional and powerful mechanism for cultivating the soil on personal and land plots. The unit performs the following operations:

• loosening the soil;
• plowing of the site;
• crushing and embedding weeds in the ground;
• cultivation;
• uniform mixing of fertilizers with the ground in the cultivated area.

Landowners often attach additional trailed and attached equipment to the walk-behind tractor, which are sold separately. The functionality of the unit increases, it transforms and begins to perform other agricultural work:

• weeding of row spacings;
• hilling of vegetable crops;
• cutting ridges and furrows;
• mowing grass vegetation;
• filling with soil of cultivated plants during processing;
• clearing the territory from snow;
• transportation of cargo.

For a walk-behind tractor, such trailed and attached equipment as:

• pololniki;
• hillers;
• lawn mowers;
• mower "String";
• snow blower SMB-1M;
• protective disks;
• trailer trailer TPM;
• special wheels with grousers;
• motoblock shovel;
• extension.

These mechanisms are widespread and in demand in agriculture among farmers.

The machine can handle areas up to 0.2 hectares. It is used on soils of medium and heavy types. The manufacturer does not recommend processing soil containing hard materials, as well as hard-to-reach places. This leads to damage to the Tarpan walk-behind tractor.

The device can withstand various climatic conditions and be operated at a temperature of + 5 ... + 40 ° С.

The agromodule has small dimensions - 1300x700x1060 mm, weight - 45 kg, does not require a large storage area. It can be transported in any convenient way:

• by car;
• on a trolley;
• partially disassembled manually.

For this purpose, the 2 main units are separated from each other by releasing the eyebolts.

The walk-behind tractor consists of the following main units:

1. Power unit, which includes:
   • internal combustion engine;
   • docking mechanism;
   • automatic clutch;
   • governing bodies.
   • The executive block, which consists of working mechanisms:
     • reducer;
     • rotary cultivator;
     • deep regulator.

Power units with the following motors can be used in the Tarpan unit:

• with a carburetor 4-stroke engine Briggs & Stratton (USA), model 12/802;
• with Honda engine (Japan), model GCV-160.

The working volume of the Briggs Stratton is 190 cm³, the Honda - 160 cm³.

At the same time, the Briggs internal combustion engine with forced air cooling allows to develop power up to 6 hp, the service life is within 1000 hours. The maximum power of a motor cultivator with a Honda engine is 5.5 hp.

The steering of the unit is simple and convenient. This working body adjusts the position of the handles. When the steering wheel is turned to a horizontal plane, the soil is cultivated. When transporting equipment, the steering wheel on the walk-behind tractor is turned towards the engine.

Using the remote control lever, the engine speed is changed or its operation is stopped.

The centrifugal clutch starts the walk-behind tractor. When the required number of engine revolutions is reached, a large torque is transmitted to the gearbox.

A 1-stage worm gearbox with an oil bath serves to transfer power to the working bodies of the machine.
