Plowing work requires considerable physical effort on the part of man. But there is a technique by which this task is significantly accelerated in its implementation. The article will discuss the Zubr motoblock - a machine that can significantly alleviate the fate of a farmer or gardener.
Short description
First of all, it is worth concentrating on the ratio of price and quality of the unit. The Zubr motor-block by its indicators is ranked as an average price indicator, however, its highest reliability and functionality also allows it to be ranked as a premium class. Thanks to the presence of a removable seat for the driver and the wheel located under it, it is quite possible to attribute the device to the category of mini-tractors.
The Zubr diesel walk-behind tractor is equipped with a differential lock system, which, in turn, provides the car with high maneuverability and maneuverability, which is extremely important for such a powerful vehicle. The operator’s considerable weight also plays into the operator’s hands, as this provides an excellent opportunity to plow even difficult and heavy types of soil without problems.
In its basic configuration, the Zubr walk-behind tractor is equipped with twelve-inch wheels with a high chevron tread. This ensures simplified operation even on loose snow. The track to be machined will have a width appropriate for the attachment. As for the gauge of wheels, this indicator is in the range from 65 to 73 centimeters.
Management Features
The motorized unit is controlled by special handles that the user acts on during the operation of the machine. On these handles are the main control elements. It is worth noting that the use of a driver's seat reduces the maneuverability of the unit, therefore, it requires especially precisely in this case to set the motion vector. And most importantly: to deploy a walk-behind tractor requires considerable physical strength, and therefore only a strong, physically strong person can drive it. Thus, the walk-behind tractor is not intended for women.
Gear box
The Zubr motor-block, the diesel engine for which is the main type of fuel, has two forward speeds and one rear. The creators of the machine provided for the possibility of functioning at reduced speeds, which ultimately ensures the presence of six gears. Each of the gears of the gearshift mechanism is made of stainless steel with a high carbon content. The service life of such gears is very long.
The gearbox mechanism is well closed from the external environment, and its crankcase is filled with oil, the replacement of which, in principle, is not required (an exception may be a leak).
In addition, it is possible to connect a second gearbox under the motor. Thanks to this combination of mechanisms, power is increased, but the speed and progress of work are reduced. Such a tandem of equipment is optimal when it is necessary to process difficult soil or transport a large load.
A few words about the motor
Let's consider what engine the Zub motor-block has. A diesel engine is exactly that version of the power plant that engineers chose when designing the unit. The motor itself is a four-stroke with a horizontal arrangement. Fuel is supplied directly to the combustion chamber by means of a single injector, and this, in turn, increases the power and efficiency of the engine, and reduces fuel consumption.
The ignition system is electronic, and therefore it is able to work stably even at extreme ambient temperatures. Since it is extremely difficult to ignite diesel fuel in winter, the Zubr walk-behind tractor is also equipped with mechanical ignition with a decompressor.
Full protection against overheating of the motor is guaranteed by a water-type cooling system, which is much more efficient than its air counterpart. In parallel with it, heat is also removed by lubrication, the spray of which is carried out by a gear pump.
One cannot but mention vibration. During operation, of course, it is, but does not affect the operation of the unit. All vibration phenomena are damped due to the weight of the motor itself, the frame. At the time of control, the return to the hands is felt, but not critical.
Parameters and accessories
Depending on the needs of users, the machine can be aggregated together with:
- Potato digger.
- Potato grower.
- Shovel blade.
- By the plow.
- Boronoy.
- Flat cutter.
- Okuchnik.
- Wheel extensions.
As for the technical characteristics, the walk-behind tractor has the following main indicators:
- Dimensions - 2170x845x1150 mm.
- Ground clearance - 210 mm.
- Weight - 290 kilograms.
- The mass of the motor is 115 kilograms.
- Power - 11.4 horsepower.
- Engine displacement - 815 cubic cm.
In general, the Zubr walk-behind tractor, the price of which ranges from 54,000 to 71,000 Russian rubles, has received overwhelmingly positive feedback from its users.
