Modification MB-1070D
This version is equipped with a continuous-action single-plate clutch, which ensures smooth starting and braking of the device. The gearbox is mechanical, mixed type with a wide range, driven by a cylinder drive. Excellent maneuverability and high cross-country ability are ensured by a differential with forced locking and a large diameter of the running wheels.
The ring-type brake assembly is equipped with internal expansion pads. When using the unit for transport purposes, such a system adds convenience, safety and reliability of operation. Two V-belts provide transmission from the engine to the gearbox. The presence of a rear power take-off shaft makes it possible to interact with an active-type cutter at a cultivation depth of eighty to one hundred and forty millimeters (width - 70 mm). The Centaur walk-behind tractor of the MB-1070D series is equipped with a plow and a cutter.
User manual
This paragraph describes in detail the stages of assembling the walk-behind tractor, shows diagrams with descriptions of components, mechanisms and individual parts, and describes the principle of operation of the walk-behind tractor.
In addition, this section may contain other valuable information:

- how to attach this or that attachment.
You can download the instructions for the Centaur walk-behind tractor in electronic form using the link: Operating instructions for the Centaur 2070D walk-behind tractor
First start
The startup procedure includes two steps:
- preparation;
- launch.
Oil 85W-90 Oil 15W-40 Oil SG
Preparation includes the following steps:
- adding oil (oils for four-stroke engines are used: synthetic, semi-synthetic and universal, depending on the season);
- filling fuel (diesel or gasoline AI-92, depending on the engine);
- checking the reliability of bolted connections;
- tire pressure monitoring.
The startup procedure itself is described in detail in the manual.
Run-in
During the running-in process, all moving parts of the engine and the walk-behind tractor gearbox are ground in, the functionality of all components and mechanisms is checked, and the operator has an excellent opportunity to adjust the gearbox by checking all speeds.
Break-in for gasoline and diesel engines occurs differently; it is important to study the instructions before starting the walk-behind tractor.
However, for a diesel and gasoline walk-behind tractor in both cases, the procedure begins with warming up the engine, idling and gradually increasing power over several hours (about 10). At the end of the running-in period, it is necessary to completely change the oil in the crankcase of the Centaur walk-behind tractor.
Maintenance
The instructions contain a complete list of work that must be carried out in a timely manner to ensure the operation of heavy equipment. We will describe the daily actions that ensure the maintenance of the walk-behind tractor in working condition.
Before starting field work:
- add fuel and oil;
- check tire pressure;
- make sure the mounting bolts are securely tightened.
After field work;
- thoroughly clean and wash the walk-behind tractor;
- dry in the shade;
- Lubricate the mechanisms with appropriate lubricant.
Basic malfunctions and ways to eliminate them
Let's list some possible breakdowns.
The device of the Centaur walk-behind tractor
Gearbox noises:
- poor quality lubricant;
- the oil is running out;
- the bearing is broken or incorrectly installed;
- the gears are broken.
The cutters do not rotate:
- the clutch cable is loose;
- belts burst;
- the rotors are clogged with dirt or stones;
- the bolts came loose.
The engine stalls and does not start:
- fuel is missing or of poor quality;
- the fuel supply system is clogged;
- the filter is clogged or damaged;
- problems with spark plugs (for gasoline walk-behind tractors);
- The injection pump has failed (for diesel cars);
- problems with the carburetor (gasoline models).
Adjusting the main mechanisms
To initially provide the walk-behind tractor with optimal performance characteristics, it is necessary to configure some of its systems and mechanisms. In particular, the adjustment applies to the drive belt, clutch, steering wheel and brake system.
The drive belt must have sufficient tension, otherwise its slack will affect the power, as a result of which the Centaur walk-behind tractor will not be able to transmit sufficient force to the working parts. The four screws under the engine should be varied in tightening to ensure proper tension. The release brackets will help you adjust the clutch. To adjust the brake, you need to tighten the spring of the mechanism by first moving the clamping lever. The steering is adjusted as follows: the pin and cotter pin on the lever are loosened, after which the steering tension is adjusted.
Mini tractor based on a walk-behind tractor
Very often, owners of equipment decide to re-equip, improve the purchased walk-behind tractor, make attachments for it with their own hands, etc. Owners of more productive and heavier models often convert the Centaur walk-behind tractor into a mini tractor. Owners of small walk-behind tractors prefer to use an adapter (a seat on a frame with an additional wheel/s). We invite you to watch a video on how to make a mini tractor from a Centaur walk-behind tractor with your own hands.
Overview of the operation of a mini tractor based on the Centaur walk-behind tractor
Often, household and semi-professional walk-behind tractors move too quickly across the field, not having time to properly penetrate the soil and properly cultivate it; the operator has to run after the walk-behind tractor, which keeps breaking out of his hands. In such cases, it is recommended to install a creeper for the Centaur walk-behind tractor, which can be ordered from the manufacturer or made by yourself. Speed reducers are either chain or gear (gear).

Reviews
The unit as a whole leaves a positive impression on the owners. Speaking in general terms, what comes to the fore is the performance that distinguishes the Centaur walk-behind tractor. Reviews indicate that it successfully copes with large properties of 1 hectare. Of course, even on small plots it will show the same quality result, but its capabilities will probably be many times greater than the demands of small private farms. The owners also note the versatility of the device: hilling a bed, mowing grass, cutting furrows and delivering the dug and collected root crops to them is no problem for the Centaur.
But there are also negative reviews. For example, there are many complaints about the work of the cutter, which shows unsatisfactory results in neglected areas where it is necessary to get rid of excess weeds. In particular, many note that the grass literally wraps around the working element, causing the motor to stop. But on the other hand, this is rather a problem of improper maintenance of the cutter, since in an optimally sharpened state it cuts even some varieties of shrubs quite well.
