Comparison Daewoo DAST 5040Li vs Daewoo DAST 3000E

— Petrol. An internal combustion engine that uses gasoline as fuel. Such engines are often more powerful than electric ones, and do not depend on being connected to the mains or the length of the power cord. On the other hand, gasoline snow blowers are usually heavier, have a higher noise level, and emit combustion products into the air. In addition, they are more expensive to operate and require the purchase of fuel and lubricants. You should pay attention to such machines if you plan to work on large areas and/or in the absence of electricity.

— Diesel. Internal combustion engines running on diesel fuel. It is easier to achieve high torque in such engines than in gasoline engines; however, this requires sacrificing speed, but this is not critical for snow blowers. In addition, diesel fuel is cheaper than gasoline. On the other hand, the engines themselves are quite expensive and difficult to maintain, and at low temperatures they often have problems starting. Therefore, diesel engines are not very widespread; they are found only in a few models of heavy professional snow blowers.

— Electric(mains). Snow blowers with electric motors are usually powered by a regular 230 V mains. Compared to gasoline ones, such devices are lighter, cheaper to operate, produce less noise and do not pollute the air; in addition, they are more compact and easier to sto...re. On the other hand, the power of electric snow blowers is usually significantly lower, and mobility is limited by the length of the power cord. Such models can be recommended primarily to those who plan to clean relatively small areas in the immediate vicinity of power sources - for example, the yard of a private house or the exit from a garage.

— Electric (battery). Snow blowers with an electric motor, powered by a built-in battery. Such models have very low power and limited operating time, while they are more expensive and weigh more than their mains-powered counterparts. On the other hand, a battery-powered snow blower works without being connected to the mains and does not depend on the length of the wire. So such a unit will be an ideal choice for cleaning a relatively small area near which there are no sockets.

The width of the strip of snow that the snow blower can clear in one pass. The larger the capture width, the fewer passes will be required to process the site, which is especially important on large areas. On the other hand, for processing small spaces, clearing individual paths, etc. significant width is not required (moreover, a “narrow” snow blower will pass more easily in a hard-to-reach place). The larger the capture width, the more powerful the engine, usually, ceteris paribus.

The most compact modern snow blowers have a working width of less than 50 cm, these are mainly electric models of low power, although gasoline units are also found. A width of 50 – 60 cm can be called relatively small, 60 – 70 cm — medium, and in the largest models this figure exceeds 70 cm.

The maximum thickness of the snow layer that the snow blower removes in one pass. If you plan to regularly remove snow as it falls in a small area (for example, in the courtyard of your own private house), a grip height of up to 20 cm will be enough. If the opportunity to remove snow is rare (for example, in a country house where you visit only on weekends), you should pay attention to more powerful models with a height of about 50 cm.

The maximum distance to which the snow blower can throw the collected snow (for models without throwing distance adjustment, the operating range itself). This value is rather arbitrary, since snow can be strongly dispersed in flight. Nevertheless, it characterizes the capabilities of the unit well and allows you to compare it with other models.

Long range is important mainly when working on large areas — it allows you to throw snow across the cultivated area so that it does not have to be collected a second time. As for specific figures, the value up to 10 m is considered relatively small, 11 – 15 m — average, and in the most "long-range" models this figure can be 16 m or more.

The speed of rotation of the working tool of the snow blower.

Other things being equal, a higher speed is good for performance, a lower speed gives more torque and improves efficiency in hard snow and crust. However, in fact, this parameter is more of a reference than practically significant: manufacturers select the speed in such a way as to ensure sufficient efficiency and productivity. In addition, many models are produced with several gears, where the rotation speed can be adjusted.

Snowblower motor power in watts. This designation is used for all electric models; for units with an internal combustion engine (see "Motor type"), the designation in horsepower may also be given (see above).

The higher the motor power, the higher the snowblower's flow rate, the better it copes with high dense snowdrifts and icy crust. However, more powerful engines consume more fuel, weigh more and cost more, and their use is not always justified. Detailed recommendations on choosing the optimal power for a specific situation can be found in special sources.

Nominal voltage of the battery used in the unit with the corresponding engine type (see above). Theoretically, a higher voltage allows you to achieve more power, but in fact there is no direct relationship between these points. In addition, manufacturers choose batteries to deliver the intended power, rotational speed, and other performance. Therefore, in the selection and normal use of the unit, this parameter has a secondary, reference value; it may be needed mainly for some specific tasks, for example, searching for a spare battery or a “non-native” charger, or comparing different batteries by capacity (see below).

The name of the battery that is compatible with the device. It helps to buy a spare or find a suitable one in case of a breakdown of the main one.

Features of the battery that the snow blower of the corresponding design is equipped with (see “Engine type”). This item is relevant only for those models, the equipment of which differs from the classic version of the “unit + battery”, namely:

— Not included. No battery included. This option is not very convenient at first glance — the snow blower cannot be used out of the box, you need to purchase a battery. On the other hand, this battery can be chosen at your own discretion, without relying on the decision of the manufacturer. Also, this configuration option is useful for those who already have a suitable battery “in the household”.

— 2 batteries. The presence of two batteries at once in the scope of delivery of the snow blower. This configuration affects the price, but it also has its advantages. The most obvious of them is the doubled battery life: when the charge is exhausted, you can replace the dead battery with a fresh one and continue driving. Moreover, in this way, you can also reduce the breaks for charging: while one battery is in use, the second can be charged. At the same time, such capabilities are rarely required, and most battery-powered snow blowers allow you to purchase a second battery separately if you wish. Therefore, this configuration option has not received much distribution.
