User Guide

The manual is an invariable companion to every Centaur engine block. This document must be studied before starting operational work. The instructions contain the following points:

  • The first start of the power plant.
  • Walk-behind tractor.
  • Servicing a motorized device.

The Centaur MB 2081D walk behind tractor uses flammable liquids such as diesel fuel and oils (transmission, engine). All this requires special skills from the operator, which are needed when refueling, maintenance, as well as working with the device.

Active Tailor Tailor

The working body of any walk-behind tractor is soil cutters, which consist of sharp rotating knives mounted on an axle. Inexperienced or careless handling of the machine while milling can result in serious injury or serious injury to the operator or his family.

First run and run-in

The instructions contain a detailed step-by-step description of the first start of the engine. Following this recommendation will extend the life of the device. Before you start for the first time, do the following:

  • Pour oil into the engine crankcase.
  • Fill the tank with fuel.
  • Tighten the screws and nuts more firmly.
  • Check tire pressure.

Once the engine has started, it needs to be run in, which prepares the two-wheel tractor for heavy loads in the field.

owner reviews

Roman, 33 years old:

“Motoblock MB2081D is hardy, stable, dimensions allow you to work both in raspberries and in a greenhouse in open ground, rushing like a tank – with mill mills, a plow, a trailer. Of course it would be better to add speeds to it, but then the price would have grown a lot. “

Nikolai, 28 years old:

“I have this model for the second year. Last season MB 2081d worked without outcrops. I greatly facilitated all the processes with potatoes – they planted 1.5 hectares per day, collected just as quickly. The perch and spray also went with the participation of a centaur. Not far into the new season I’ll see how I survived the preservation. So far, during a cursory inspection, no rust or peeling paint. “

Sergey, 54 years old:

“I have 1 of the earth. I stuck with the MB 2081D model due to its relatively light weight and excellent features. I tried a car with other problems. The milling is beyond praise, although I had to walk twice in some spots where the ground was more difficult. I managed it myself, now I’m working at the dump – both winter and summer will come in handy. “
