Motor type

Petrol. Internal combustion engine on gasoline. Such engines have good power, are easy to operate and are not limited by the length of the power cord (like electric ones). Their disadvantages are a significant noise level, exhaust emissions and the need to purchase fuels and lubricants, as a result - a fairly high cost of operation. However, most walk-behind tractors and cultivators have gasoline engines.

Diesel. An internal combustion engine similar in design to a gasoline engine, but with a number of differences in the operating principle and, as a result, in operation. Thus, it is fueled with diesel fuel, which is somewhat cheaper than gasoline. Diesel engines have good torque at low speeds, due to which they are well suited for heavy work (plowing, transporting goods). On the other hand, they are not without drawbacks - high cost of repair and high requirements for fuel purity. As a result, diesel walk-behind tractors and cultivators are less common.

Corded electric. Electric motors powered by an electrical network, most often a regular household 230 V. The advantages of all electric motors over gasoline/diesel ones are, in particular, low cost (including in operation), smaller dimensions and weight, ease of maintenance (almost none required), low noise level and absence of exhaust gases. On the other hand, their power is relatively low — even for...models powered by the network it does not exceed 3 kW. Therefore, electric units are mainly made for small volumes of work, which are more like cultivators than full-fledged walk-behind tractors. It is also worth noting here that when powered by the network, the mobility of the unit is limited by the length of the power cord. On the other hand, models with such power are generally more powerful than battery-powered ones, with similar power — lighter and cheaper, and the operating time is practically unlimited.

— Battery. Electric motors powered by batteries. The main features of electric motors are generally described above, and battery power makes the unit as autonomous as possible, independent of sockets and the length of the power cord. At the same time, models with such power are even less powerful than devices connected to the network - most of them do not even reach 1.5 kW. In addition, the battery affects the weight and cost of the unit, and the operating time is limited; charging the battery takes a lot of time and still requires a power source. So it makes sense to use cultivators of this type only when the volume of work is small and there are no sockets nearby; such situations occur extremely rarely, so this option has not become widespread.

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.

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.

Engine size

The working volume of the gasoline or diesel engine of the cultivator / two-wheel tractor. For an internal combustion engine of the same type (see "Type of internal combustion engine"), power and fuel consumption usually directly depend on the volume. Also, the classification of a two-wheel tractor as a vehicle according to the traffic rules of a particular country may depend on the engine volume; you should pay attention to this if you plan to use the unit as a tractor and drive on roads.

Motor power

Horsepower of two-wheel tractor/cultivator motor. The basic unit of power nowadays is watt, however for petrol and diesel engines (see "Motor type") the more traditional designation in horsepower is often used. 1 hp is approximately equal to 735 watts.

More powerful motor allows achieving higher productivity, width and depth of processing. On the other hand, high power significantly affects the price, weight and dimensions of the unit, as well as the consumption of electricity/fuel. In light of this, the engine characteristics are selected by the manufacturer taking into account what "weight category" the walk-behind tractor belongs to. The most limited modern units have a power of up to 2 hp, in the heaviest and most advanced this figure can exceed 13 hp ; 4 - 7 hp can be called an average indicator, and 2 - 4 hp and 7 - 13 hp are below and above average, respectively.

Detailed recommendations on the optimal power for a given situation can be found in specialized sources.

Motor power

The power of the two-wheel tractor/cultivator engine in watts. This designation is usually used for electric engines, but can also be used for petrol/diesel engines, along with horsepower (for more information, see the "Motor power" section above).

More powerful motor allows achieving higher productivity, width and depth of processing. On the other hand, high power significantly affects the price, weight and dimensions of the unit, as well as the consumption of electricity / fuel. In light of this, the engine power is selected by the manufacturer taking into account what "weight category" the walk-behind tractor belongs to, what characteristics it should show. So, the lightest models have a power of up to 1.5 kW, this is the device that is best suited for a small area of 6 - 8 acres. Walk-behind tractors up to 3 kW can cope with 10 - 15 acres, a power of 3.5 - 5 kW is suitable for a plot of 50 acres to a couple of hectares. Units for 5 - 10 kW are already classified as professional level, they can "tame" spaces of 7 - 10 hectares; and the heaviest and most powerful modern walk-behind tractors have a power of more than 10 kW.

Start type

The method of starting a petrol or diesel engine (see "Motor type") provided in the unit.

— Manual. Starting by human muscle power: the operator pulls a special cable or turns a handle, which causes the shaft to rotate and the engine to receive the initial impulse necessary for operation. Manual starting systems are inexpensive, lightweight and compact, and do not depend on batteries that can run out at the most inopportune moment. On the other hand, the starting process itself may require significant effort, especially in a heavy, powerful engine. Therefore, this option is used mainly in relatively low-power models.

Electric . Starting with starter — small electric motor powered by a battery. Such systems are much more convenient than manual ones — the operator is actually required to press a button or turn a key; they are suitable even for the most powerful motors. On the other hand, a starter with a battery significantly increases the weight, dimensions and cost of the entire unit, and if left idle for a long time, the battery may run down, and the system will become useless (however, a spare manual "starter" may be provided for this case). Therefore, this starting method is used exclusively in heavy equipment, for which the ability to do without manual starting is more important than the described disadvantages.

Fuel consumption

The average amount of fuel consumed by the gasoline or diesel engine (see "Engine type") of the cultivator/two-wheel tractor per hour of operation. This value is rather conditional, because depending on the mode of operation, fuel consumption may vary in one direction or another; however, in general, it provides an estimate of the approximate amount of fuel required for a given operating time.
