Description of the MB-1 walk-behind tractor

Motoblocks MB-1 are very popular in our country. They began to be produced in the 80s and are constantly being improved. Their traction class is 0.1, with additional and trailed equipment. This figure indicates the pulling power of the vehicle.

Attached equipment allows the cultivator to plow the soil, huddle it, loosen it, dig up roots and rake the grass. Various loads are transported using a trailer. The optimal cultivated area is 6-40 ares.

After purchasing the MB-1 unit, you need to carefully study all the recommendations presented, which are contained in the operation manual.

For the MB-1 cultivator, the characteristics are as follows:

• The main part on which all units are mounted is the cylinder block.

When working with the MB-1 motor cultivator, the operating instructions will help the farmer understand the main aspects of the unit's operation.

There is another walk-behind tractor from a Chinese manufacturer, which is approved by our GOST. This is a MB-2 m walk-behind tractor. The motor power of the walk-behind tractor is 6.5 hp. It copes well with the soil and at the same time spends little gasoline. In user reviews regarding the Chinese model, there are complaints about parts that are not made of metal, but of plastic. With intensive work, there is a minus in one: cutters often break and the starter cord is torn.

Forza walk-behind tractors from the UralBenzoTech manufacturer, which produces improved equipment, as well as spare parts and attachments, are also popular.The basic model is the FZ-01-6.5F cultivator. They have a modern design, they are quite reliable and durable.

All about belts for walk-behind tractors Cascade

Features of belts for motor-blocks Cascade

There are not so many models of Cascade walk-behind tractors on the agricultural market, but it is necessary to accurately select all the missing components for the existing models. Any discrepancy, even the smallest, can lead to very rapid belt wear. That is why the manufacturer strongly recommends purchasing only belts of its own production.

Each manufacturer of agricultural machinery uses belt drives, but they are far from always interchangeable - a belt for a walk-behind tractor from one manufacturer may not fit a walk-behind tractor of another. Even models of motoblocks from the same manufacturer may have differences in belts. That is why it is imperative to look at the marking and catalog number in the operating manual.

Production of belts for the walk-behind tractor Cascade

Modern belts for the Cascade walk-behind tractor (their sizes can be of any size) are made of the following materials:

• polyurethane;
• rubber.

The functionality of this agroelement is due to the cord (this is the name of the main belt part). Cord is made from polyester, steel and Kevlar materials, specialized fabrics, fabric cords.

The size of the belts for the walk-behind tractor Cascade

From practice: the reverse belt on the walk-behind tractor Cascade is used much less often than the front one. Consequently, the front elements wear out faster, although as a rule, belts can last even a year for the groomers. But it happens that the "life span" of a belt component is calculated in days. Some farmers have found a solution to this problem in the fact that they purchase agricultural accessories from foreign motoblocks (with internal teeth), which fit the Cascade in size. The size of the belt marking on the Cascade walk-behind tractor is A-1180 or A-1213 GOST 1284 (for forward gear), A-1400 (for reverse gear). Profile "A" is thirteen millimeters. The marking number will help to make the correct order of the fixture from the catalog.

Replacing the drive belt on the cascade walk-behind tractor

Tensioning belts on walk-behind tractors is a simple and quick job. To make the correct belt replacement on the Cascade walk-behind tractor, use our instructions:

In neutral, turn off the tiller.
Stop the engine.
Remove the protective cover.
Remove old, worn out belts. If they are not torn, but simply worn out, cut them open.
Connect new agricultural accessories. First, remove the pulley from the motor drive. Pull the belt over the geared pulley (the latter remains in place), then install the motor pulley

It is important to double-check that the belts are not twisted and are located in the strictly designated areas.
Reinstall the protective cover.

• the gas tap is closed;
• clogging of the fuel system;
• clogged hole in the tank plug;
• fuel leaks out of the carburetor;
• the ignition system does not work;
• sucking air into the carburetor through the flanges.

With unstable engine operation, the reason is low fuel consumption, with difficult starting and the presence of exhaust gases - on the contrary, high fuel consumption, clogged air filter, excess oil in the crankcase.

If the engine is not operating at the rated power, then the problem is a weakening of the spring or carbon deposits in the combustion chamber.

Carburetor breakdowns are best corrected by a specialist.

In case of minor malfunctions of the walk-behind tractor, the owner can eliminate the cause on his own.

In case of problems with the fuel system, the following actions must be taken:

1. Add fuel.
2. Check for clogging of the hole in the plug. To do this, you need to remove the plug in the tank, clean the hole.
