Comparison Karcher LMO 18-36 Battery Set 1.444-421.0 vs Makita DLM380PM2

The capture width provided by the unit, in other words, the width of the strip of land cultivated in one pass. In fact, this size corresponds to the width of the working nozzle.

The large working width is useful when processing large open spaces, as it allows you to finish the job in a small number of passes. On the other hand, for hard-to-reach places, relatively narrow tools are better suited, able to go where a wider unit will not fit. In addition, the width of the tool directly affects the weight and price.

In general, it makes sense to compare in terms of working width only units of the same type (see above). However, it is worth noting here that trimmers do not differ so much from each other — most models capture from 25 to 45 cm (and a wide processing band is provided by moving the nozzle from side to side). As for the other types, in the most modest models the capture width does not exceed 40 cm, in the heaviest and most powerful it can be 56 – 60 cm or even more(in mini tractors — up to 1.5 m).

The minimum cutting height provided by the lawnmower — that is, the smallest height of grass that can remain after the passage of the machine. It makes sense to pay attention to this indicator mainly in cases where the lawn is planned to be cut as short as possible. In addition, the lower the minimum height (with the same maximum), the wider the height adjustment range of this model.

The maximum cutting height that the lawn mower can achieve is the maximum height of grass that can be left after the machine has passed.

This parameter is relevant mainly for those cases when you want to leave the grass on the lawn relatively long. In addition, lawn mowers with high cutting heights have a wide range of mowing adjustments.

The number of cutting height settings provided by the lawn mower. The more such settings (with the same adjustment range) — the more accurately you can choose the mowing height. Note that in some robots (see "Type") this number reaches 30 or more with a range of 30 to 60 mm; in other words, you can select the height to the nearest millimetre.

Possibility of work of a lawn-mower in the mode of a mulching.

Mulching is the chopping and automatic spreading of mowed grass over the site. This is one of the most convenient and at the same time practical methods of vegetation disposal. So, it does not need to be collected, and the resulting coating (mulch) performs a number of useful functions: it fertilizes the soil, reduces its heating and evaporation of moisture in hot weather, and also keeps the top layer loose.

Note that some lawn mowers allow you to use a nozzle purchased separately for mulching. However, such models are not included in this category: mulching in our catalog is indicated only for models that support this function out of the box.

The volume of the grass clipping bag supplied with the lawn mower. Manufacturers select this volume depending on the power, performance and overall level of the unit, however, similar models may differ in this indicator. In such cases, it is worth considering that a larger bag takes longer to fill and needs to be unloaded less often, but it weighs more and takes up more space (even when empty). Mostly the difference in the volume of the bag is 5 liters and there are lawn mowers for 35, 40, 45, 50, 55, 60, 65, 70 and more liters.

The presence of a soft start system in the lawn mower engine.

The design features of electric motors are such that when power is applied directly, the start occurs very abruptly — both in a mechanical and electrical sense. Firstly, the engine itself spins up in a jerk, in a very short time, which increases the wear of its parts. Secondly, at the moment of start-up, there is a sharp jump in current strength, which creates significant loads on the power grid (or the batteries of the unit). The soft start system eliminates these phenomena: it limits the starting current, allowing the motor to accelerate smoothly and preventing voltage surges.

On the other hand, additional electronic circuits affect the cost, sometimes quite significantly. So there are few models with this feature nowadays, and you should pay attention to them mainly in cases where the mentioned advantages are of fundamental importance — for example, if the device is purchased for a house with weak wiring that does not tolerate voltage surges.

Features of the battery-powered lawn mower (see "Engine type"). Most modern models of this type are initially equipped with one battery, but there are exceptions. They are indicated in this case, the options can be as follows:

- Without battery. This option is intended primarily for tech who do not want to rely on the choice of the manufacturer and would like to choose a lawn mower battery of their own choice. Theoretically, this may be associated with additional troubles, however, in practice, batteries are often sold literally "next to" the tools - on the nearest rack or in the next section of the online store. In addition, many brands make batteries universal - for example, a battery from a drill can be put in an electric trimmer. So such equipment will also come in handy for tech who already have a cordless tool on the farm - the main thing is to clarify compatibility before buying.

— 2 pieces in a set. Includes two replaceable batteries. The most obvious advantage of this configuration is the increased battery life: when the charge is exhausted, it is enough to change the dead battery for a fresh one. However, in addition to this, this option provides other advantages. So, it allows you to reduce interruptions for charging: one of the batteries can be charged at a time when the second is used for work. In addition, even if one battery fails, the s...econd will remain operational; and the probability of simultaneous failure of both batteries is extremely low (and definitely lower than that of a single battery). On the other hand, you will have to pay extra for a second power source - although often its cost is less than if a spare battery was purchased separately.

The name of the battery platform supported by the device. A single battery platform is used to combine various power tools of the same brand (drill, grinder, saw, etc.) into one line. Devices on the same platform use interchangeable batteries and chargers. Thanks to this, for example, there is no need to select a battery for each individual model of a power tool, because one purchased as a spare battery can be used in various power tools, depending on the situation or as needed. Batteries of the same platform basically differ from each other except perhaps in capacity.
