Cultivator is a very valuable technique in the personal household. But without a motor she does not represent any benefit. Of great importance is also the exact motor installed, what is its practical properties.
To correctly choose engines for cultivators, you need to clearly understand what the specificity of the cultivating machines themselves. They prepare and process the soil with a rotating cutter.
The properties of the power plant are determined by:
- how deeply you can scratch the earth;
- What is the width of the processed strips;
- Fully loose plot.
Types of motor systems
On motorcultivators can be used:
- Two-stroke gasoline engines;
- Rechargeable power plants;
- Drives with a four-stroke gasoline engine;
- Network electric motors.
Usually an electric motor is used on the easiest devices. Ultralight and lightweight types of cultivator can also work from a two-stroke gasoline engine. Their feature is the execution of the working cycle for 1 crankshaft turnover. DVS with two working clocks is easier, easier to execute and cheaper than four-stroke analogs.
However, they spend more fuel, and reliability turns out to be much worse.
Is it worth using chinese engines?
Judging by the experience of most farmers, such a decision is quite justified.
Products from Asia differ:
- low noise;
- affordable price;
- minor sizes;
- Long operation.
A classic version of Chinese equipment is four-stroke engine with a single cylinder. Cooling the walls is made due to the natural circulation of air.
A typical engine device (not only chinese) contains:
- Starter (launcher), spinning crankshaft to the necessary revolutions;
- Fuel supply unit (from fuel tank to carburetor and air filters);
- ignition (set of parts generating sparks);
- cooling elements;
- Gas mixture distribution system.
It should be noted that there are noticeable differences between specific versions of Chinese engines. They are most often installed on the cultivators of the budget category. Lifan 160f model deserved popularity. In fact, adaptation of the engine model Honda GX.
Although the device is inexpensive, consumes little fuel, it is bad limited power – 4 liters. with., Therefore, it is not enough for all works.
Ignition in this single-cylinder motor produces an electronic system. It is cooled by a distilled impeller air. Run is made only manually. Judging by the reviews, run the engine to work is easy. It is equipped with a lubricating oil indicator, which is extremely useful in everyday service.
A more efficient solution in many cases is the engine 168F. It is also launched exclusively in manual mode. In addition to the oil indicator, the generator light winding is provided. Shared power reaches 5.5 liters. with. Lifan 182F-R is a high-quality diesel engine with a total capacity of 4 liters. with. Increased in comparison with gasoline analogues. Price is due to a more significant resource.
For cultivators and motoblocks equally suitable gasoline engine model Union UT 170f. The four-stroke engine is equipped with a single cylinder, which is cooled by the air jet. Supply does not include the necessary pulley. The total capacity is 7 liters. with.
Other features such:
- The total volume of the operating chamber of the motor 212 cm ³;
- launch only manually;
- Capacity of gasoline tank 3.6 l.
Tecumseh motors instruction manual indicates that they are compatible only with SAE 30 oils. With negative air temperatures, it is necessary to use oil 5W30, 10W. If strong cold occurs, The temperature drops below -18 degrees, you need SAE 0W30 grease. The use of all-season lubricants at a positive air temperature is unacceptable. It leads to overheating, oil starvation and damage to motors.
For the engine Tecumseh is suitable exclusively gasoline brands AI92 and AI95. Ethyl seeds of fuel are not suitable. It is not recommended to use long-stored gasoline.
Experts recommend to leave the upper 2 cm tank free from fuel. This will help to avoid its spill during thermal expansion.
No matter what motors put on cultivators in the factory conditions, it is often necessary to increase turns. Often do it, increasing the stretch of the spring so that it overcomes the force of the device covering the damper.
If the engine structurally allows you to change the turnover, the strength of the workprint stretching is adjusted using the gas cable.
When operating a cultivator with any motor, it should be run by all the rules prescribed by the manufacturer.
It is forbidden to use fuel worse than the recommended fuel brands. Ideally, they should be limited. It is forbidden to use any motors with removed or filled fuel tank caps.
- Fill new fuel until the motor stops;
- consumption of non-certified lubricants;
- Installation of unofficial spare parts;
- making changes to the design without coordination with suppliers and manufacturers;
- smoking during refueling and other works;
- Drain flammable.
