Motoblocks Centaur. Characteristics, attachments, maintenance, instructions

The diesel walk-behind tractor "Centaur" combines high quality and affordable price. Numerous user reviews prove the veracity of these facts. The equipment belongs to the heavy MB type. She is able to cope with increased loads.

The centaur walk-behind tractor was created to perform work tasks on different types of soil. It is especially popular and in demand among farmers who cultivate large plots of land. This model compares favorably with the previous ones. Previously, cars were equipped with only one clutch disc, which caused the quality and time of work to suffer. MB 1081 D has a clutch with two discs, which allows you to operate the walk-behind tractor longer; it works much more efficiently on dense soil.

One of the positive aspects is the eight-speed gearbox. It makes it possible to use the equipment in different soil conditions and with different types of attachments. The highest MB speed is 21 km/h, and the lowest limit is 2 km/h.

The designers gave the MB a ring-type coupling, which protects it from overloads. Its task is to switch the drive going to the gearbox. Speeds are switched manually. The V-belt type transmission makes the Centaur mechanism more reliable. The steering wheel of the Centaur diesel walk-behind tractor has three positions. It is easily adjustable, regardless of whether attachments are used or not.

A distinctive feature of the “Centaur” 1081D is the plow, designed with the ability to change its position in relation to the machine. With this design, you can easily carry out excavation work, grab soil right next to the wheels, and plow in hard-to-reach places. The electric starter is considered very convenient in Centaur; the employee can start the equipment manually.

Heavy walk-behind tractors are equipped with large diameter wheels with high tread. Thanks to the heavy weight and solid power, ultra-high maneuverability is ensured; the machines successfully cultivate heavy and virgin soils.

Caterpillars on a walk-behind tractor

In winter, wheels can be replaced with tracks. They increase the area of ​​contact between the device and the ground, thereby improving its progress.

Thanks to the transport track adjustments and high ground clearance, hilling of tall plants is possible. For better traction with the soil in lightweight models, it is recommended to use metal wheels with lugs. When working on difficult soils, weights are used.

The Centaur excels at plowing the land with a reversible plow. Plowing occurs as follows: the first rut is made, then one wheel is placed in it, and the plow is lowered into the ground. Thus, the second track buries the first.

Such functional devices as a potato planter and potato digger are widely used in combination with Centaur walk-behind tractors.

The potato planter has the following device: in front there is a plow that breaks a rut, and potato tubers fall into it from the tank along a conveyor belt. Two hillers are buried behind the trench.

potato digger MB 1080-1012

The most popular nowadays is the vibrating potato digger. In front of it there is an active knife, which cuts the layer of earth and feeds it to the screen, where the clods of earth are broken and only fruits remain.

Sometimes, when used in conjunction with additional units, it is necessary to increase the traction force of the Centaur.

In such cases, a creeper is used to reduce the number of revolutions of the drive wheels when working with a hiller, blade, rotary mower, adapter, potato digger, trailer, garlic planter.

The creeper is an additional gearbox that is installed on the body of the walk-behind tractor, which makes it possible to reduce the speed of its movement, while increasing traction, and ensure more efficient execution of heavy options.

In winter, you can convert the walk-behind tractor into a snow blower. A simpler attachment for snow removal is a plow blade.

This is a sheet of metal curved in an arc and located at an angle, with an active knife installed at the bottom for cutting hard layers of snow.

Additional items

Any walk-behind tractor turns into nothing without attachments. Here, manufacturers did their best, equipping their equipment with all kinds of devices for cultivating the land. Please note that the basic package includes a tiller and a plow.

Attachments for "Centaur"

In most cases, this is quite enough to perform arable and sowing work. If you want to expand the functionality of the equipment, you can purchase the necessary attachments.

Manufacturers offer the following devices:

• Harrow.
• Rake.
• Trailed equipment (trolley).
• Hay mower.
• Potato digger.

Please note that on some models you can install a seat, which will turn the walk-behind tractor into a mini-tractor. True, for this you will have to install an additional wheelset. Given these features, farmers have long dubbed the equipment a “workhorse”.

However, it was not without its drawbacks. The build quality of some models leaves much to be desired, so before the first launch, it makes sense to tighten up all the elements.

User manual

Proper maintenance and operation of the walk-behind tractor for its intended purpose helps to extend the service life and improve the performance of the equipment. This does not require special knowledge or high costs, and the most correct recommendations are those offered by the manufacturer.

• Running in the car

This is done to ensure rational grinding in of the main elements of the engine and gearbox, strictly following the maintenance instructions, loading the walk-behind tractor step by step: first at 1/3 power for 3-4 hours, then at 2/3 power.

The first oil change in the engine is performed after the first break-in stage.

This rule should not be neglected, since after assembly the engine will certainly leave debris and foreign objects that, if they get into the oil, cause the engine to jam immediately after starting operation.

• Change of oil

The first oil change in the gearbox should be done after 25 hours of operation, subsequent intervals - after 100-250 hours of operation or 1-2 years in case of storage. Some owners do not follow this recommendation and practically do not change the oil in the gearbox; at best, they monitor its level and simply top it up.

In gasoline engines, only motor oils of classes SE, SF, SG, and AI-92 gasoline should be used. Diesel engines require oil of class CA, SV, SS, CD and high-quality diesel fuel.

Main malfunctions of walk-behind tractors

Any equipment, at the end of its life, fails. Unfortunately, it is impossible to avoid this, but it is quite possible to delay the occurrence of annoying breakdowns and malfunctions and delay impending repairs as much as possible.

A prerequisite for long-term uninterrupted operation is compliance with the operating mode recommended by the manufacturer, in accordance with the operating instructions - without peak loads.

Gasoline and diesel air-cooled walk-behind tractors cannot be operated at idle speed, as this leads to overheating and premature engine failure.

If the engine does not start:

• Check for fuel and spark plug
• Adjust the throttle position;
• Clean the air filter and fuel tank
• Pour the correct mixture into the carburetor.

The motor gets very hot:

• Insufficient oil or low oil level;
• The ventilation or engine is dirty;
• A foreign object has entered the muffler.

If the spark disappears, clean the spark plug cap from dirt and carbon deposits. This malfunction, as a rule, only affects single-cylinder engines.

If the walk-behind tractor vibrates strongly, this is a signal that the cutters are installed incorrectly, are damaged, or the fasteners are loose.

Regular preventative maintenance will help extend the life of Centaur walk-behind tractors, thanks to which you can most likely detect minor flaws, preventing more serious malfunctions in time.

Diesel engines develop higher power at low speeds than gasoline engines, and their parts wear out less. Therefore, the service life of a diesel engine is higher.

And in order to extend its life, according to the instructions, after every 100 hours of operation, the diesel walk-behind tractor needs to work at full load for 2-3 hours.

Don’t forget about high-quality oil for your diesel walk-behind tractor and keep the air filter clean - this will also help delay repairs.

Definitely: the key to a long engine life is timely maintenance and compliance with operating recommendations in the instructions or in our articles.

Equipment

Centaur walk-behind tractors go on sale in the following configuration: instructions for use, the fully assembled walk-behind tractor, an active tiller and a rotary plow. Special devices allow soil cultivation in places where a conventional plow cannot reach. The depth of penetration of the plow into the ground is 190 mm. The cutter was equipped with saber-shaped knives. With them, the worker easily fights weeds and loosens the ground.

When purchasing a MB, you need to understand that it requires regular inspection and repair. Proper handling will help minimize the occurrence of breakdowns and malfunctions. The brake system and spring require adjustment; for this, each speed level is checked separately. The tension of the drive motor and clutch elements may require adjustments.
