Comparison Daewoo DABC 4PRO vs Daewoo DABC 4ST

- Bladed knife. A knife in the form of a pair of blades, rotating around a vertical axis in the manner of a propeller blade. Two blades are the most popular, almost standard option for rotary lawn mowers (see "Cutting System"). Note that in the case of trimmers, the use of a knife allows you to achieve higher productivity and better cope with thick grass than using a line reel. On the other hand, blades do not tolerate contact with stones and other hard objects very well; in case of such troubles, various tricks can be provided (for example, an automatic engine brake).

- Spindle knife. Nozzles used in spindle-type lawn mowers. For more information about such units, see "Cutting system", here we recall that spindle knives are inferior to bladed ones in terms of performance and efficiency in thick grass, however, they provide a "cleaner" cut, which allows you to give the lawn the most accurate appearance. So this option is well suited for regular cutting of relatively sparse, well-groomed vegetation.

- Reel with fishing line. Most often used in trimmers (see "Type"). According to the general principle of operation, it is similar to a bladed knife (see above), however, in this case, the working tool is not blades, but pieces of thick fishing line rotating at high speed. The main advantage of the fishing line over a bladed knife is its almost complete insens...itivity to collisions with stones and other solid objects: such a “blade” will only bend from impact and literally immediately straighten due to centrifugal force. True, such nozzles cope with thick stems somewhat worse, but in practice it all depends on the thickness of the fishing line (see above) and the speed of its rotation.

- Cultivator. Nozzle designed to loosen the soil. Outwardly, it is a set of gears mounted on a horizontal axis with teeth of a specific bent shape. Due to the rotation of these wheels, loosening is carried out. Combisystems are mainly equipped with such nozzles (see "Type"). At the same time, the width of the cultivator is usually small, it is poorly suited for full-fledged garden work, but it can be useful when processing a small flower bed or several beds.

- Saw blade. Attachment for cutting relatively thick, stiff stems (e.g. bushes or small tree branches). Mounted mainly on trimmers (see "Type"). Outwardly, such a nozzle is very similar to the working element of a circular saw: it uses a rotating rim with characteristic teeth along the edges. The rim may have holes - to reduce weight.

- Scissor mower. In this case, it means a special attachment, most often used in mowers (see "Type"). Such a nozzle has the form of a characteristic horizontal "comb" with two rows of teeth moving relative to each other. Its design is described in more detail in the “Cutting system - Scissor” section, here we note that hay trimmers are indispensable when working with dense vegetation and thick stems, they easily cope with thickets that are “too tough” for other attachments.

- Without nozzles. The absence of any nozzles in the regular configuration of the lawn mower. It is assumed that the customer will purchase them separately for specific needs.

The size of the engine installed in the petrol or diesel model (see "Engine type"). Power directly depends on this indicator, however, only engines of the same type can be compared by volume (see "Type of internal combustion engine"). And even in the same type of units of the same power, the volume can be different. In such cases, note that a larger volume means more fuel consumption, but the engine itself may cost less than a smaller one.

Lawnmower engine power expressed in horsepower. The common unit of power these days is the watt, but gasoline and diesel engines (see "Engine Type") are traditionally referred to as hp. Some units are easy to convert to others: 1 hp. approximately equal to 735 watts.

In general, the more powerful the engine, the more performant the mower is and the better it handles with heavy work such as cutting thick grass, bushes, etc. On the other hand, high power has a corresponding effect on fuel consumption, as well as the weight and price of the engine. In addition, it should be taken into account that different types of mowers (see "Type") differ in terms of power requirements. For example, among trimmers there are many models with a capacity of 0.7 – 1.3 hp., for gasoline lawn mowers, the minimum power is already in the range of 1.3 – 2 hp., and for mowers, at least 2.5 hp is required. . So you can only compare units of the same type in terms of power. Detailed recommendations for choosing a mower depending on its type and features of the planned work can be found in special sources.

Lawnmower engine power expressed in watts. This designation is used absolutely for all electric models (see "Engine type"), and it is also often found in gasoline and diesel units along with horsepower (these units are clearly related, 1 hp is about 735 watts).

In general, the more powerful the engine, the more performant the mower and the better it will cope with heavy work such as cutting thick grass, bushes, etc. On the other hand, high power has a corresponding effect on fuel / electricity consumption, as well as the weight and price of the engine. In addition, note that the power requirements depend on the type of mower itself and its engine (see above for both). For example, for most robots, the power does not exceed 500 W — more, taking into account specialization, is not required, besides, otherwise the devices would turn out to be too bulky and heavy. Trimmers and lawn mowers of similar power are only electric, and the power limit for power tools is 2500 – 3000 W when powered from the mains and 1500 – 2000 W for battery models. But in gasoline tools, the minimum power is about 500 – 1000 W for trimmers and 1000 – 1500 W for mowers; the maximum value can exceed 4 kW.
