Tarpan motor cultivator malfunctions and their elimination. The walk-behind tractor stalls: causes and solutions to the problem

The Tarpan cultivator is a domestic product. The devices are produced by Tulamashzavod, a diversified enterprise that produces military and civil products, including small-scale mechanization equipment and road-building equipment. The technical capabilities of the plant allow it to carry out a full range of metalworking and protective coatings, and numerous subsidiaries make the plant almost completely independent of third-party organizations.

Tarpan motor cultivators are known not only in Russia, but also far beyond its borders - the equipment is supplied to the CIS countries, as well as near and far abroad.

Now we will look at the design features of walk-behind tractors and cultivators made in Tula, and give recommendations for selecting a model based on technical characteristics and the needs of owners of summer cottages and farms.

Advantages and disadvantages of Tarpan brand cultivators

Since Tarpan motor cultivators are assembled at an enterprise belonging to the defense industry, the plant’s products are distinguished by high quality and reliable assembly. The first models began to be assembled in the early 90s, when the production crisis forced the company to look for alternative directions of development. Lack of experience left its mark on the first cultivators - they could not compete with the products of foreign manufacturers. However, after introducing new technologies and concluding contracts with leading manufacturers of engines for agricultural machinery, Tulamashzavod was able to assemble equipment that meets the most stringent technical requirements and standards.

The competitive advantages of modern Tarpan motor cultivators include:

• Reliable, durable motors from leading industry manufacturers;
• High build quality, technical performance;
• Adaptation to domestic operating conditions;
• Low maintenance, high maintainability;
• A wide selection of attachments allows you to expand the range of work performed.

The disadvantages of the devices include a fairly small number of service centers and company representative offices, which creates certain difficulties in the process of servicing and repairing equipment. However, this drawback is compensated by the simplicity of the design - if necessary, following the instructions in the user manual, the owner of the cultivator will be able to independently eliminate most of the malfunctions.

Characteristics

All cultivators offered by the company are equipped with standardized control handles mounted on a fixed steering column. The handles are adjustable in angle of inclination; during transportation, the parts are folded, reducing the dimensions of the equipment. On the handles there are controls connected to the actuators by steel cables passed through the shells. Cable drives are equipped with special adjusting couplings.

The width of the processed strip is 350-1100 mm, depending on the power and modification of the cultivator. Motors can be removed for installation on a four-wheel lawn mower, which is purchased separately. This design expands the scope of application of agricultural equipment and makes it easier to care for lawns in front of country houses.

Model range and modifications

The model range of Tarpan cultivators is represented by electric and gasoline devices, which makes it easy to choose a model based on personal preferences and operating conditions.

Let's look at the motor cultivators that are most popular among domestic buyers.

Service Features and Operating Instructions

The instruction manual is the main document of the cultivator, which contains a description of the design, as well as rules for operation, maintenance, storage and transportation. Compliance with the rules will help the owner increase the service life of the equipment and ensure safe working conditions.

First launch and run-in

After assembly, the new cultivator undergoes a conservation procedure necessary to protect the mechanisms from corrosion. Before the first start, the owner must unscrew the spark plug, wash it with gasoline, and also rotate the crankshaft 10-15 revolutions to remove preservative lubricant.

In most cases, engines are supplied without engine oil. It should be remembered that malfunctions caused by dry operation of the motor are not covered by warranty. The oil must be selected based on the ambient temperature and the recommendations of the engine manufacturer.

During the first 12 hours of operation, the cultivator is run in - the friction pairs of all moving units are run in. During the break-in process, it is not recommended to use the cultivator at full power.

Upon completion of the break-in, it is necessary to replace the engine oil, which contains chips and other by-products of running in the cultivator components.

Changing the oil in the gearbox

According to the requirements of the operating manual, after the first 5 hours of operation it is necessary to change the oil in the gearbox. When selecting a lubricant, you must follow the requirements of the operating manual.

Most gearbox models are designed for oils with API GL-4 or GL-5 approval. Using the wrong lubricant, for example TAD-17 or NIGROL, can quickly damage the gearbox.

Replacing oil seals

During operation, under the influence of external factors, mechanical damage to the gearbox seals may occur, which leads to oil leaks from the mechanism. If the cultivator is still under warranty, we recommend contacting your nearest service center. An alternative option is to replace the seals yourself.

Before performing work, it is necessary to drain the oil from the gearbox. You should also note the spatial position of the shaft relative to the housing to eliminate the possibility of incorrect assembly.

Possible faults

If you do not have experience in repairing or servicing cultivators, we do not recommend troubleshooting them yourself. Unqualified intervention can aggravate the situation.

The starter squeals, the cord comes out

It may squeal if there is a lot of grease on the balls. You need to clean the balls and the places in the ratchet where they are inserted.

The cultivator made several pops, the speed began to “float”

Most likely, the power system cannot cope, or the fuel level in the tank is low, the float axis may be skewed and debris may have gotten under the needle valve, you need to remove everything and check the air filter and jets.
