  • Fuel filling (diesel or gasoline AI-92, depending on the engine);
  • Checking the reliability of bolted joints;
  • tire pressure control.

The commissioning itself is described in detail in the manual.


During the break-in process, all moving parts of the engine and the gearbox of the walk-behind tractor are lapped, the performance of all components and mechanisms is checked, the operator has an excellent opportunity to adjust the gearbox by checking all speeds.

Break-in for a gasoline and diesel engine is done in different ways. It is important to study the instructions before starting the tiller.

In both cases, however, for a diesel and gasoline walk-behind tractor, the procedure begins with the engine warming up, idling and gradually increasing power over several hours (about 10). At the end of the running-in period, a complete oil change in the crankcase of the Centaur two-wheel tractor is required.

Mini tractor based on a walk-behind tractor

Very often, equipment owners decide to re-equip the purchased walk-behind tractor, improve it, 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. Small walk-behind tractor owners prefer to use an adapter (a seat on a frame with an extra wheel/wheels). We offer you to watch a video on how to make a mini-tractor from a Centaur walk-behind tractor with your own hands.

Overview of how to operate a mini tractor based on the Centaur walk-behind tractor

Often domestic and semi-professional walk-behind tractors move too quickly across the field, not having time to properly penetrate the soil and finish it with high quality, the operator has to run after the walk-behind tractor, which every now and then breaks from his hands. In such cases, it is advisable to install a creeper for the Centaur walk-behind tractor, which can be ordered from the manufacturer or made by hand. Creepers are chain and gear (gear).

Reviews about the Centaur mb 1070d are mostly positive. It is functional and powerful, suitable for any attachment.

Leonid, Odessa:

I mainly use the mb Centaur 1070 Diesel on the ground when cultivating and planting – digging up potatoes. There are many household chores in bulk: with a trailer, a shovel, a pump. I have no regrets, although I paid a large amount at one time, now you can find cheaper.

Nikolai, Sumi:

I was convinced that it’s better to plow my land with the wheels removed, I put cleats on it so it’s much better. Centaur 1070d has been working on my farm for 4 years, I am satisfied but it is a bit heavy.
