Working width

The maximum width of the strip of land processed by the machine in one pass.

The large width makes it easier to work in large open areas, allowing them to be dealt with faster. At the same time, it is easier to deal with bottlenecks and hard-to-reach nooks and crannies with a small working width — a large unit may simply not fit where a smaller one will pass without problems. So it is worth choosing according to this indicator, taking into account the features of the planned work. If we talk about specific numbers, then in the smallest models the capture width does not exceed 50 cm, in the largest it can be 1 m or more, a value from 50 to 75 cm can be called average, and from 75 cm to 1 m — above average.

Also note that some models allow you to expand the processing width by installing additional cutters. However, note that the wider the band, the more power is needed for efficient operation. It is believed that for the full use of the two-wheel tractor, it must produce at least 1 hp. for every 20 cm of width; however, for loose soils and shallow depths, smaller values are sufficient.

Number of blades

The number of cutters that the two-wheel tractor is equipped with. Note that for models with active rototillers (see below), this parameter is not indicated: such attachments are removable, and active rototillers with different performance characteristics can be installed on one unit.

Speaking of quantity, a cutter means a separate "asterisk" of several curved knives installed on the working axis of the unit. The number of such “stars” is selected depending on the processing width that the manufacturer wants to provide: one cutter captures a strip on average from 12 to 18 cm, and several of them are needed for a more or less decent working width.

Reducer

The type of gearbox provided in the design of the two-wheel tractor.

The gearbox is a mechanism for transmitting rotation from the motor shaft to the working shaft; the speed of rotation is reduced, and the tractive effort, respectively, increases. In modern units, worm, chain, gear and gear-chain gearboxes can be used; here are their main features:

— Worm. Gearboxes based on a worm gear are mainly used in light two-wheel tractors with passive cutters (motor cultivators). With simplicity and low cost, such a gearbox provides a high gear ratio, which makes it possible to achieve good traction at a relatively low engine power. Other advantages of worm gears include compactness, minimum noise level, smooth running and self-braking ability. On the other hand, such gearboxes do not tolerate high loads, which determined the scope of their application.

— Chain. Gearboxes based on a chain drive — two gears connected by a chain (similar to the mechanism used in bicycles). Such gearboxes are somewhat more expensive than worm gears, but they are more reliable and able to work with higher loads. Another advantage lies in the small width of the body, which is especially important for motor cultivators — the gearbox does not limit the depth of processing, since it can be buried in the soil simultaneously with the cutters.

...— Geared. The most advanced type of modern gearboxes. Such mechanisms are highly reliable and durable, they normally endure long-term work at high loads. The downside of these advantages is the high price. Gear reducers are used mainly on professional equipment, for which "endurance" is critical.

— Gear-chain. A compromise option, which, when installed on a motor cultivator, increases its performance (compared to chain and worm), and when installed on a motor block, slightly reduces the cost of the latter.

Number of gears

The number of gears provided in a self-propelled cultivator / two-wheel tractor, in other words, the number of travel speeds. There are both the simplest two-wheel tractors for 1 gear or 2 gears, as well as more advanced ones with three, four and even 6 gears. Lower gears are not fast, but they allow you to effectively cope with high loads, and are also better suited for starting from a place; higher ones give low tractive effort, but good speed. Thus, the presence of several gears makes it possible to adjust the operating mode of the unit to the specifics of the situation. The number of gears is also relevant for reverse gear, because there are walk- behind tractors and cultivators for 1 gear or more.

Motor model

Model of the engine installed in the two-wheel tractor / cultivator. The main performance data of the engine is usually indicated in the general data for the unit. However, knowing the exact name of the motor, you can find more detailed information on it — starting from specific data like torque or revolutions and ending with reviews and reviews. Also, data on the engine model can be useful when searching for spare parts or consumables.

Fuel tank volume

The volume of the fuel tank of the cultivator / two-wheel tractor; knowing this parameter and fuel consumption (see above), it is possible to determine the maximum operating time of the unit on a single refill. If you plan to use the device in large areas or to work for a long time, it makes sense to look for a model with a large tank — it will not have to be filled often. On the other hand, for short-term work in small areas, a large tank is not required — in this case, it only increases the weight and dimensions of the unit.

Wheels diameter

The diameter of the main wheels of the two-wheel tractor / cultivator. For flat areas, a small diameter is enough, and for difficult terrain, large wheels are better suited — they are much easier to cope with pits, bumps and various obstacles.
