Max. processing depth

The greatest depth to which the aerator nozzle is able to penetrate the ground during operation.

This parameter is relevant primarily for models that support verticutter functions (see "Type") — the very format of operation of such units implies "biting" into the ground. For scarifiers, the processing depth is often not indicated at all, because. they work mostly above the surface.

Max. processing height

The highest processing height provided by the aerator.

This parameter describes the maximum height above the lawn surface that the working head can be raised to. It is of practical importance only for models with scarifier functions (see "Type"): it is this type of aerator that allows you to leave the space between the working nozzle and the soil surface untouched during operation. This can be useful, for example, when removing debris from a previously fertilized lawn. But in the case of verticutters, the maximum height only affects the convenience of transportation: the higher the nozzle can be raised, the higher obstacles the unit can overcome without hitting it with knives.

Number of depth settings

The number of nozzle depth adjustments provided in the design of the aerator. Note that we can talk not only about the depth, but also, in the case of scarifiers, about the height of processing (for more details, see above). Anyway, the more depth (height) settings, the wider the choice of the operator, the more accurately he can choose the optimal value for a particular situation.

Shaft speed

Rotation speed of the aerator shaft in normal operation.

Manufacturers select the shaft speed in such a way that the device is guaranteed to be able to cope with the tasks for which it is designed. So in most cases, this parameter is more of a reference than practically significant. At the same time, for verticutters (see "Type"), it can also have a practical meaning: lower speed, with the same power, provides higher tractive effort and allows you to better cope with dense soils and thick rhizomes. So for such conditions, it is worth choosing a model with lower revolutions, and for a favorable environment, on the contrary, higher (high revolutions have a positive effect on performance).

Working mechanism

The design of the working mechanism provided in the aerator, in other words, the number and types of working elements installed on the shaft. For verticutters (see "Type") such elements are blades, for scarifiers — spring teeth. For combined models, in this case, the design of both working shafts is indicated, for example "14 knives / 20 spring teeth".

Bag volume

The total volume of the garbage collection bag provided with the aerator.

The larger the bag, the more garbage it can hold, the less often it will have to be emptied. On the other hand, the weight and dimensions of a capacious container will also be considerable (this is especially true for rigid varieties, in which the size does not depend on fullness — see "Bag Type"). Yes, and carrying too much garbage “with you” is not always convenient, especially with the small size and weight of the unit itself. Therefore, manufacturers, usually, choose this parameter taking into account the specifics of the use of the aerator. So, in low-power models designed for small areas, the volume of the bag is also small, and in high-performance professional devices it can exceed 50 liters.

Motor power

The power of the aerator motor, expressed in watts. Today, the watt is the common unit of power and is used for both electric and petrol models (see "Engine type"). In general, the more powerful the motor, the higher the performance of the unit, the greater the depth of processing and the working width (see above) can be provided in the aerator; however, the consumption of electricity / fuel also directly depends on the power. Therefore, when choosing an engine for their equipment, manufacturers proceed from a reasonable compromise between these properties, and in general, engine power allows you to evaluate the performance of the unit and its suitability for large volumes of work.

Noise level

The noise level produced by the aerator during operation. It is worth noting that this indicator can be indicated in different ways: some manufacturers give the maximum noise level in the characteristics, others give average values \u200b\u200bduring normal operation, etc. Anyway, this information allows you to assess the noise level of the unit and, if necessary, provide protective measures — for example, get headphones in advance.

When evaluating specific loudness values, note that the decibel used to indicate the noise level is a non-linear value. Therefore, it is easiest to evaluate specific values using comparative tables. Here is a simplified table for the range that most modern aerators fit into:

70 dB — a conversation of several people in raised tones.
75 dB — high power vacuum cleaner.
80 dB — traffic noise on a busy street.
85 dB — motorcycle engine with muffler in close proximity;
90 dB — freight car at a distance of 7 – 10 m;
95 dB — noise in the subway car on the stage;
100 dB — industrial shop.
