Subtleties of choice and popular models of diesel engines for a walk-behind tractor

Motoblocks with diesel power units and a water cooling system are reliable and versatile assistants in summer cottages and farms. It is from the diesel installation that the characteristics and features of the operation of the walk-behind tractor depend.

One of the most important parameters of a power unit is its power. It is on it that the maximum size of the territory that can be processed with a walk-behind tractor depends. Therefore, in the process of choosing a device, you need to take into account the size of the suburban area on which the walk-behind tractor will be used. If the area is less than 10 acres, then it is best to choose a 5 horsepower engine. But if it is necessary to process an area of ​​100 or more acres, you will need a more powerful power plant (at least 10 hp).

In addition, when choosing the optimal diesel power unit, you should pay attention to other characteristics.

• Weight and dimensions. The smaller the diesel engine, the easier it will be to work with the walk-behind tractor.
• Fuel consumption level. If you buy a model that can boast of economy, then in the future you can spend less money on the purchase of fuel. This is extremely important in cases where the device has to be used frequently.
• Starter. Different versions of starters can be installed on walk-behind tractors. The most popular are hand and spring models. But electric models are not used, since they need large and heavy batteries to work.
• Price. For most summer residents, it is the price that is the key criterion in the process of choosing a diesel engine for a walk-behind tractor. Of course, there is no point in buying a premium unit in order to use a walk-behind tractor once a year. But on the other hand, buying a model that is too cheap can result in unnecessary expenses of time and money due to the need to constantly carry out repairs and change parts. It should be borne in mind that in many respects the cost of the unit depends on its capacity.

Before purchasing a particular model, it is also recommended to read consumer reviews on specialized forums. This will provide information about the durability of the device, the complexity of its maintenance, the real level of fuel consumption and other issues.

Yanmar is an internationally recognized manufacturer of diesel power units that can be used in walk-behind tractors. The company's products are of high quality, compact dimensions and impressive power. One of the advantages is the minimum level of fuel consumption, which favorably distinguishes the company's models against the background of competitors.

In addition, Yanmar diesel engines are highly adaptable to almost any lubricant., which greatly simplifies their operation. The most in demand today are Yanmar twin-cylinder powertrains, which boast centrifugal speed governors, starter starting, valve control and other innovative systems.

A huge number of diesel engines are presented on the modern market, which are of high quality and reliability. The 186 FBE model deserves special attention, which has a capacity of 9 horsepower.Thanks to this, the single-cylinder motor can cope with the processing of a large area without problems. In addition, this model is distinguished by the presence of a direct fuel injection system. The only drawback of the unit lies in its large mass, which complicates the process of using the walk-behind tractor. The tank capacity is 5.5 liters, which is quite enough for daily use of the unit.

The diesel engine KM 186FA is also very popular today, which is considered the most striking example of advanced developments in the field of diesel mechanisms. This model is extremely convenient to use because the design includes not only a manual, but also an electric starter. This provides additional adjustment options.

Despite the fact that diesel fuel is supplied, it will not work to fill in any oil. According to the manufacturers, the SAE10W30 would be the ideal solution. The use of other varieties can negatively affect the durability of the unit.

This diesel engine has a power of 6.6 kW, is small in size and weight. This has a positive effect on the operation of the model. In addition, the new product boasts a minimal level of fuel consumption and a small amount of noise during operation. The air-cooled, four-stroke, single-cylinder engine is a good choice for any walk-behind tractor.

The Magnum LD 178 F engine is installed on a huge number of motoblocks. It is a four-stroke power plant that is characterized by high quality and reliability. In addition, this model boasts an impressive 3.5-liter fuel tank. This is quite enough even for processing a large area. The starting system of the Magnum LD 178 F is presented as a manual trigger with a return spring. The model also has a decompressor.

A walk-behind tractor, like any other technical device, needs careful use and constant care. Oil plays a huge role in this process, which ensures stable operation of the power plant. However, it is necessary to figure out what kind of oil can be poured into a particular engine, since the durability of the unit depends on this.

Of course, the most correct option will be the one indicated in the instructions for use. It is necessary to carefully read the document and strictly follow it. If this information is not specified, you can use the classification of the American Petroleum Institute.

• API CJ-4 oil will be an excellent solution for devices with high power. We are talking about power units that produce 10-12 horsepower. Such installations are subjected to enormous loads on a regular basis. This type of oil fully complies with the regulations on particulate matter emissions.
• CH-4 can be used exclusively on four-stroke power plants that run on diesel fuel. The main advantage of this oil is its minimal sensitivity to fuel quality.
• CF-2 oil will be an excellent option for motoblocks that differ in two-stroke power units. The product contains special additives that provide reliable protection of the power plant against wear and have a positive effect on durability.

Sometimes situations may arise when the work of the walk-behind tractor is not as smooth as we would like. There are several main reasons for this problem.

• Poor PCV performance, causing oil to flow back into the powertrain. To solve this problem, you need to replace the PCV valve.
• Mechanical malfunction of the diesel engine, which causes too much oil consumption. In this case, it is necessary to check the compression.
• Old valve seals that allow oil to enter the engine.These parts should be checked regularly and replaced if worn.

As is clear from the above, diesel power units are considered the ideal solution for walk-behind tractors. They are characterized by a low level of fuel consumption, which is especially important when the equipment is used regularly. When choosing, be sure to pay attention to the power of the installation, the type of oil to be filled, and other technical parameters.
