Race and start first

If you prepare for the first start of the power plant, you must ensure the following:

  • The fuel is flooded into the fuel tank until the desired level.
  • The oil in the crankcase is flooded.

If all indicators are normal, you can turn on the engine. The operating instructions describe this process in detail. Next, we begin the walk behind tractor break-in (also called break-in). The burn-in takes five to ten hours, during which the engine is hardened and all parts are lapped.

Running-in begins with idling, after which the loads gradually increase.

After the 3rd hour of running-in, the oil is drained from the crankcase and fresh oil is poured in, then the running-in is continued for another 4-5 hours, bringing the engine speed to maximum.

Technical service

Proper care of the device will ensure that it will function properly for a long time. This includes the following procedures:

  • regular replacement of engine oil (the table is available in the instructions);
  • Care of a walk behind tractor before and after field work;
  • Preservation of the device during long-term storage.

  • filter – if it is clogged, the engine will not start;
  • fuel supply hoses;
  • carburetor;
  • the condition of the spark plugs – a burned or wet candle must be replaced, a smoked one can be cleaned;

The lack of rotational movement of the cutting edge or mandrel may indicate:

  • the clutch cable is loose;
  • the mounting screws are loose and need to be tightened;
  • Straps are stretched or torn.

owner reviews

Vasily, 29 years old:

“Motoblock bought last season. The break-in went without any problems, the engine runs like clockwork. This winter I shoveled snow, at temperatures down t o-5 the car starts without any problems, at lower degrees you have to sweat a little. Engine power is excellent, but I try not to overload the car, I drive around the site 2-3 gifts with cutters, the bottom is fluff.

Stanislav, 33 years old:

“I’ve had a walk behind tractor for the fourth year now, for two years I’ve been using it together with an adapter, it’s much better to do field work – no strain on the legs, everything is like on a tractor. I grow potatoes, there is everything you need attachments. Happy with the purchase.”

Eugene, 41 years old:

“Last year I bought this centaur. Everything worked for the first week, but then suddenly the gearbox started to rumble. I immediately went to the forum, the guys suggested what to do. Oil refilled, screws tightened, the noise stopped. Now I always try to ask what and what to buy, so I bought a vibrating potato harvester, a rotary mower – the guys tell me what to pay attention to, since store consultants are not always competent in this matter.

Sergey, Lipetsk:

Centaurus 2090. Big, power is enough. If you often have to do something, it is better to take gasoline, especially if the problem is with a diesel engine. The adapter has been installed and it is more convenient for me to drive 3 km to the field than to walk. And at least work all day. And there are no comments on quality and work.

Mining or how to use unnecessary stones

Max, Kursk Region:

The Centaur gasoline 2090 first saw with a relative, tried to work, liked it. I got it for myself, already the second season. It works well with a plow, a dump. In the virgin lands I go through the cutter 2 times, I try not to overload. No problem .
