Comparison Daewoo DAT 4555 vs Hyundai T500

The maximum working depth provided by the unit. In cultivators with non-replaceable cutters, this parameter is determined primarily by the diameter of the cutter, in walk-behind tractors designed for active cutters (see below) - by design features (in such models, even high power does not guarantee a large working depth). The most limited indicator in modern walk-behind tractors is up to 20 cm, and a value from 21 to 25 cm can be called small. However, often even such opportunities are quite enough. Depth from 26 to 30 cm already provides quite extensive opportunities, and the most advanced models are able to “bite into the ground” by more than 30 cm.

Be that as it may, the optimal depth of processing depends on the type and condition of the soil, as well as the crops for which the soil is being prepared; detailed recommendations on this subject can be found in special sources. So it does not always make sense to look for a model with maximum depth - especially since such capabilities require high power. Also note that in many units the depth can be adjusted.

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.

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.

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.

Engine power of the cultivator / walk-behind tractor in horsepower. The basic unit of power these days is the watt, but gasoline and diesel engines (see "Engine type") often use the more traditional horsepower designation. 1 hp is approximately equal to 735 watts.

A more powerful engine allows you to achieve 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 electricity / fuel consumption. In light of this, the characteristics of the engine are selected by the manufacturer, taking into account which “weight category” the walk-behind tractor belongs to. The most limited modern units have a power of up to 2 hp., in the most severe and advanced, this figure can exceed 13 hp. ; 4 - 7 HP can be called an average, and 2 - 4 hp. and 7 - 13 hp respectively below and above average.

Detailed recommendations on the optimal power for a particular situation can be found in special sources.

Motor block / cultivator engine power in watts. This designation is normally used for electric engines, but can also be used for gasoline/diesel engines, along with horsepower (for these, see Engine Power above).

A more powerful engine allows you to achieve 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 electricity / fuel consumption. In light of this, the engine power is selected by the manufacturer, taking into account which “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, just such a device is best suited for a small area of 6 - 8 acres. Motoblocks up to 3 kW are already able to cope with 10 - 15 acres, a power of 3.5 - 5 kW is suitable for a plot from 50 acres to a couple of hectares. Units for 5 - 10 kW already belong to the professional level, they are "too tough" open spaces of 7 - 10 hectares; and the heaviest and most powerful modern walk-behind tractors have a power of more than 10 kW.

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.

The maximum noise level produced by the cultivator / two-wheel tractor during operation. A noise of 70 dB is comparable to a very loud conversation, 80 dB to a busy city street, 100 dB to a production shop. The lower the noise level, the more comfortable the use of the unit for the operator himself and the less inconvenience it causes to others.
