Min. cutting height
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.
Mulching
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.
Bag type
A type of bag used in a lawn mower to collect grass clippings.
—
Hard. Bags (containers) made of a hard material, usually plastic. Such a container is more convenient to unload than a soft one, it is more durable and reliable, but it weighs a little more.
—
Soft. The advantages of soft fabric bags are primarily low weight and the ability to fold after hours, which can facilitate storage. In addition, the degree of fullness of such a bag can be controlled by eye without any special indicators. On the other hand, soft bags are very inconvenient to unload.
—
Combined. Bags that combine soft and hard materials in construction; the upper part is usually made solid. This combination makes it easier to unload the bag and at the same time allows it to be rolled up quite compactly for storage.
— Is absent. The absence of a bag is characteristic of some varieties of mowing units — in particular, mowers and trimmers (see "Type"). In classic lawn mowers, it usually means that this model does not involve collecting grass — all cut vegetation remains on the ground. At the same time, most of these models have the function of mulching (see above), however, there are exceptions.
Bag volume
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.
Noise level
The level of noise produced by the device during operation. Usually, a certain average indicator is indicated in the characteristics — in the standard mode of operation; however, the actual values usually do not differ much from the claimed ones.
The lower the noise level, the more convenient the unit to use and the less tired the operator. In the case of lawn mowers, this is especially true, since such equipment is quite noisy — even the quietest models (some robots) give out about 47 – 48 dB, which is comparable to talking at an average volume. Note that the decibel is a non-linear quantity, and it is easiest to evaluate the actual loudness using comparative tables. Here is the simplest table for the values found in modern lawn mowers:
— 60 – 65 dB — talking in raised tones at a distance of about 1 m;
70 dB — loud conversation of several people at the same distance;
75 dB — loud laughter at a distance of 1 m;
80 dB — motorcycle engine, medium power vacuum cleaner.
90 dB — loud screams, freight car at a distance of 7 – 10 m;
100 dB — a subway train or a loud car signal at a distance of 5 – 7 m, an industrial workshop;
110 dB — tractor engine at a distance of about 1 m.
In addition to subjective sensations, there are specific sanitary standards that limit the impact of strong noise. So, according to European standards, noise of 85 dB is allowed to be heard without protective equipment for 8 hours, 91 dB — 2 hours, 97...dB — half an hour, and 103 dB — only 7 minutes. So when choosing a unit, you should take into account the duration of work with it — with high noise, you may need protective headphones.
