A walk-behind tractor is a very useful and maneuverable technique designed for all kinds of land work. Processing a site without this device is much more complicated and takes more free time. There are gasoline and diesel walk-behind tractors. Each of them has many advantages and disadvantages. Today we will take a closer look at the diesel options.

What it is?

Before getting acquainted with the device, the pros and cons of the walk-behind tractor, you need to understand what it is.

A walk-behind tractor is a technique related to small-scale mechanization . It greatly simplifies various earthworks. With the help of this device, you can plow the land without any problems, make furrows, and transport heavy cargo.

A good walk-behind tractor is a wonderful "helper" in the household, simplifying many work.

Advantages and disadvantages

Diesel walk-behind tractors are very popular nowadays. This technique is chosen by many people because it has many positive qualities.

This technique is characterized by an increased service life, which indicates its reliability, wear resistance and durability

• Most diesel motoblocks in their power significantly surpass gasoline options, which makes many jobs much easier and faster to cope with.
• In diesel technology, there is a more reliable engine cooling system, represented by a filter in an oil bath. Thanks to this structure, the power plant is able to last much longer. At the same time, it will be possible to use the specified equipment even in dusty areas.
• Diesel walk-behind tractors are more functional and practical than most gasoline models.
• Such a technique can function without problems in conditions of reduced speed. At the same time, it will not be subject to breakdowns or malfunctions.

• A high-quality diesel walk-behind tractor can work continuously for a long time. Breakdown or overheating of equipment in such conditions will not occur.
• Fuel consumption when using a diesel walk-behind tractor can be different, but in most cases it is very economical. So, on average, about 2-4 liters will go away per 100 km.
• Such a technique is distinguished by excellent grip on various surfaces, because in most cases, diesel-powered walk-behind tractors have an impressive weight.
• Such useful equipment is distinguished by its low maintenance requirements. These models lack the carburetor, spark plugs and magneto, which need constant adjustment.

• Despite the fact that during operation, diesel motoblocks emit a large amount of exhaust gases, the latter are safe. Technics with gasoline engines cannot boast of such qualities.
• There are many different models of diesel motoblocks on the modern market. You can choose the best option in accordance with any goals, preferences and budget of the buyer.

But modern machines running on diesel fuel are not flawless. They also have some disadvantages that must be taken into account when choosing a suitable model.

• Equipment in which the engine is started from diesel fuel costs several times more (as well as spare parts for it) than standard gasoline options. For this reason, many consumers refuse to buy diesel equipment.
• Of course, high-quality diesel vehicles are durable and wear-resistant, but this does not mean that it is impossible to break them. In the event of a breakdown of such equipment, you can face another serious problem - its repair. Repairing a diesel walk-behind tractor can cost a pretty penny, and it will be much cheaper to repair the same gasoline version.

• Most modern diesel motoblocks do not have good maneuverability indicators. They often turn out to be clumsy, which complicates the work.
• Basically, this technique makes much more noise than gasoline.
• A diesel walk-behind tractor emits exhaust gases in large volumes.

In winter, starting a diesel engine of a walk-behind tractor can be complicated. To solve this problem, you will have to purchase special antifreeze additives. If the technology does not provide for an electric starter, then it will need to be installed additionally

Varieties

Currently, there are several main types of motoblocks on the agricultural machinery market.

On sale there are:

• light motor cultivators;
• medium;
• heavy.

These models are distinguished from each other by weight, size and engine power level. All of the above parameters are interrelated. In addition, these characteristics have a direct impact on the total cost of the equipment. Of course, the lighter and weaker the technique, the less it will cost. More powerful and heavier models cost more.

Light-type equipment in most cases has a capacity of 6 liters. with., and its weight extremely rarely exceeds the mark of 100 kg. Such specimens do not have a large fuel tank. Due to the low weight, it is not very convenient and efficient to process dense and problematic soils with such models. Lightweight motor cultivators are not designed for a large amount of cultivated land.

As for modern medium-sized motoblocks on a diesel engine, basically their weight reaches 100-120 kg. The standard engine power in these models can be from 6 to 8 hp. with. In accordance with the indicated indicators, they are quite suitable for a large territory. In such conditions, this technique will demonstrate itself only from the good side. Medium type construction is designed to work with different types of soil. Of course, such copies are more expensive than lightweight ones, but in the course of operation they pay for themselves with interest.

Practical and reliable heavy walk-behind tractors are no less popular today. This technique is characterized by great power and the same great weight. On average, these models weigh from 200 to 300 kg. These devices are the most powerful (power ranges from 8-9 to 12-15 hp). They have the highest price, but they cope with their main task with a bang.

Heavy diesel motoblocks allow you to cultivate the land not only efficiently, but also quickly.

Which to choose?

If you decide to purchase a good diesel-powered walk-behind tractor, then you will need to be very careful in order to choose a really high-quality and reliable model.

Pay attention to the motor power of the selected equipment. For a fairly large land plot, it is advisable to buy more powerful specimens designed to process large areas. Medium or heavy options are ideal here. Smaller tillers will be appropriate if you have a small area in your possession.

Diesel walk-behind tractors are equipped with electric and gasoline starters . The latter consume more fuel, and start in the same way as the good old Druzhba chainsaw. As for the electric options, they have a battery that makes the equipment heavier, but they start with one click. Here the choice is yours, it follows from the fact that it is more important for you - the economy or the ease of the plant.

Pay attention to the build quality of the equipment you choose. A high-quality model will be assembled conscientiously - there will be no backlashes, as well as cracks, and unreliable parts. All mechanisms must be credible. If the structure seems flimsy to you, makes squeaks or shuffling sounds, does not start immediately and works with strange noises, then you should refuse to buy it. That is why it is so important to test the equipment before purchasing.

Choose good branded walk-behind tractors . For example, an option called "Foreman" equipped with water cooling will be very economical and durable in use. Also, models of Japanese manufacturers, for example, the well-known company Kipor, are rightfully recognized as highly efficient and durable. Consumers leave good reviews about the easy-to-operate Zarya walk-behind tractors. Diesel vehicles with a reduction gear from the Lifan brand, a multi-speed copy from the Chinese brand Profi, or a powerful "Belarus" with a power take-off shaft are very popular. There are a lot of options, like brands. Buyers have a lot to choose from.

Buy diesel motoblocks only in specialized stores. Together with such a product, you must be given a guarantee. You should not buy such equipment in questionable retail outlets and market pavilions - in such conditions, there is a high risk of getting a low-quality product that will not last long.

Design

Knowing the structure and design of a diesel walk-behind tractor is desirable not only for craftsmen, but also for ordinary owners of such equipment. With this knowledge, it is much easier to find the perfect option in the store, use it correctly and provide the necessary care. There are not so many main nodes in this technique:

• internal combustion engine;
• cooling system;
• clutch;
• gearbox;
• frame;
• shaft with a pair of large wheels;
• the system responsible for the management of equipment.

Features of operation

The walk-behind tractor must be used correctly. The first step is to run it according to all the rules. Check the oil level first. Even if the store assured you that everything is in order with the oil, it is better not to do without checking. Running with a lack of this component can seriously damage the engine.

Now you need to check the fuel pump for defects and breakdowns. To do this, unscrew the high pressure wire from the pump and injector, make the fuel line weaker, and check how the fuel flows to the pump. Fill up with fuel in serviceable equipment. Inspect all the components of the diesel walk-behind tractor. The handlebars and wheels must be connected securely, as are the clutch and throttle cables.

A motoblock on a diesel engine starts up a little more difficult than a gasoline one . First you need to set the ignition correctly. Beforehand, the equipment must be thoroughly warmed up, especially if the weather is cold outside. Use a starter if the vehicle is new. Remove the fuel tap and wait for the diesel to flow. Then screw it up again. Next, hold the decompressor with your finger, pump it several times, and then release and pull until it returns to its original place. Then press the decompressor again and turn the starter. At this stage, the vehicle should start up.

In the walk-behind tractor, you will also need to adjust the valves . With this procedure, suitable clearances are established. Their norms are usually indicated in the technical documentation (based on these documents, you can connect the equipment wiring). These procedures should be performed a couple of times a year.

In order for the battery of such agricultural equipment to last longer, you may need to open its plugs to reveal the acid level. Use the widest possible screwdriver to remove the plugs. Some people make it easier - they use a regular coin to remove the plugs. Using an aerometer, you will also need to check the density of the liquid in the plugs. The required values required will depend on the time of year.

Storing such equipment in a damp room is extremely undesirable, because this can lead to oxidation of contacts, destruction of wiring insulation, and the appearance of water in oil. All this can seriously harm the technique.

What is the difference from gasoline?

There are quite a few differences between diesel and gasoline walk-behind tractors. Let's get acquainted with the main ones in more detail.

• Gasoline engines are spark-triggered by a spark plug. Diesel variants are launched from a glow plug.
• Diesel models are in most cases larger and heavier than gasoline ones.
• Gasoline powered units emit harmful exhaust gases. Waste from diesel models is safer and more environmentally friendly.
• In the cold season, diesel models can be problematic. Gasoline units are not so afraid of low temperatures.
• Gasoline models are cooled by air systems only. Diesel engines can be cooled not only by air, but also by water systems.
• A walk-behind tractor that runs on gasoline is usually more maneuverable. When working with a diesel machine, a person has to make more effort to operate.
• Diesel units are more expensive than those that run on gasoline.
• Gasoline devices are quieter than diesel ones.
