Technical characteristics

Features of the Walk behavior tractor

• The gearbox has 2 front speeds and 1 reversal, which means that the use of machine output is rationally used depending on the type of work carried out.
• The weakened passive cannons are attached to the gear selection wave with a hitch in the tail of a walking tractor, active devices.
• Thanks to an adjustable floor and an adjustable floor, a fixed area of ​​the floor cultivation is possible: 870/1136/1406 mm.
• Thanks to the dry coupling with several disks couplings, the smoothness of walking behavior is ensured without jerking. The high gear without circuits and belt concentrates on high loads when processing complex soils.
• Motobo block control handles are very ergonomic-comfortable adaptation in different levels, which is when working in a limited space, near obstacles or simply so comfortable that the operator does not move along the newly processed soil.
• Thanks to a special oil air filter, the lifespan of the machine is significantly increased.
• Economic fuel consumption, reduced noise and vibration level.
• A wal k-A S-D -Boden cutter with large crop protection discs (280 mm), large pneumatic bikes, a number of tools and operating instructions are equipped.

There is a version of the MB 2090 B without an electric starter, which is structurally similar to the Mot Centaur MB 2091b, in the line of petrol engine in the centaur.

Possible malfunctions

As with any technique, on a walk tractor sooner or later there may be various shortcomings, malfunctions in work. And then a logical problem of repair arises before the owners: you yourself or on duty? It’s difficult to answer unequivocally, of course, it all depends on the characteristics of the collapse.

In order for this problem to appear as later as possible, rational loads on equipment when working with hinged units and timely prevention are required.

The most important nodes are the engine and transmission and require minimal maintenance during operation. Replacing oil and checking its level, cleaning the filter element of the air filter, regular preventive examinations is enough to avoid frequent malfunctions in the future.

In order to avoid engine overheating, it is necessary to exclude the operation of the walkin g-behaviou r-tractor at idle. For air motors, this is most relevant.

Initially, after purchasing the Centaur MB 2091b, the engine runs correctly according to the operating instructions.

Let’s look at the most common malfunctions and ways to eliminate them.

1. The gearbox is very hot during work. The main causes are friction bearings, lack of transmission oil or its poor quality. It is necessary to replace oil or bearings.
2. Walk behavior tractor does not work smoothly. Check the condition of the profile on wheels, most likely it has been deleted.
3. Vibration while working. Possibly an improper connection of the hitch or not fully fixated.
4. The engine does not start well. Conduct a visual inspection for damage, check for gasoline in the gas tank and supply of fuel throughout the line. Check the ignition system for spark, evaluate the carburetor and try adjusting the fuel mixture.
5. The carburetor does not work. This part is responsible for the preparation and delivery of fuel mixture. Check the quality of fuel, disassemble and rinse the carburetor with a soft cloth dampened in gasoline to remove the resulting soil and slag. Then dry thoroughly using a compressor with air and a dry cloth.
6. oil flows. Possible: wear or improper installation of oil seals on bearings, wear of the liner, cover or input into the air valve is not pulled to the end. Check the details and clean them.
7. Motoblock “leads” during operation. It is necessary to tighten the adjusting screw.
8. skip clutch. Weaken it, if it doesn’t work, the reason may be in the flywheel. This is a device that transmits rotational torque from the starter to the crankshaft. Wear of flywheel crown teeth is possible. Repair and replacement of parts are only done in workshops.

reviews

On the forums, the quality of the assembly of the centaur’s centoblocks and their high performance is noted.

Leonid, Solnechnogorsk:

A suitable model for the middle position. Of course, if there is a lot of land, then it is better to take a heavy engine with water cooling. MB Centaur 2091b likes that it has an electric starter although the petrol engine is believed to start as well but not fail in winter. The assembly is good.

Owner reviews

Ivan, 36 years old:

“The car is very necessary, inexpensive to maintain. In connection with the attachment, I have simplified life considerably – I do the necessary work in a few hours instead of in several days. Another plus is the low price. There were no serious failures during the tw o-year operation.

Igor, 28 years old:

“My Centaur MB 2091b is already in the fourth year. During this time I tested it in different situations. It even needs virgin soil (in 2-3 approaches), comfortable control and stability enabled me to edit the country under a slope (of course via the descent). Of course, the old man fails regularly, but he can be repaired. Still no trace of rust. After a downtime, it works well, but of course not on the first attempt, as the manufacturer promises. ”

Oleg, 32 years old:

“I bought this model last year, the han d-led tractor worked perfectly, all work for planting, growing and harvesting potatoes were carried out with its help. The machine is necessary, powerful – an excellent assistant from the gardener.
