Motor type

Type of engine installed in the aerator.

Electric (mains). Mains powered electric motors. The main advantages of all electric motors, regardless of the type of power supply, are the low cost of both the units themselves and electricity, ease of maintenance, an absolute minimum of consumables (usually, you have to buy something for such a motor only in case of malfunctions or breakdowns), as well as a low noise level and the complete absence of emissions into the atmosphere. Among the shortcomings, in comparison with gasoline, one can note a relatively low power. However, in this category there are also quite solid models in terms of power, which may have problems except for the most complex work. But the unequivocal disadvantage of network aerators is the need for a nearby outlet and various inconveniences due to the presence of a power wire. However the length of this wire can be quite large, and many units of this type are quite suitable for processing a medium-sized lawn in the yard of a private house, in extreme cases, you can use an extension cord.

Electric (battery). Battery powered electric motor. Such models have all the advantages of electric motors described above; the battery makes the device as autonomous as possible, allowing you to work even if there are no outlets nearby. And the absence of a power cord, which can get underfoot, can also be attributed to dignity. On the...other hand, battery units are noticeably more expensive and weigh more than similar mains-powered models, their power is lower than that of gasoline ones, and the operating time is limited — and after the charge is exhausted, the battery needs to be charged, which takes quite a lot of time. However the latter can be partly offset by the use of replaceable batteries and the ability to buy a spare battery in such a way that one battery is charged while the second one is being used. Anyway, battery models are relatively rare; it is worth paying attention to such aerators if you need an autonomous unit, however, gasoline-powered devices are not suitable for one reason or another.

Petrol. Internal combustion engines (ICE) on gasoline. Such motors provide more power than the electric motors described above, while they are completely autonomous and do not depend on the presence of outlets nearby. On the other hand, internal combustion engines are noticeably more expensive (and gasoline is expensive for them), more difficult to maintain, very noisy and produce exhaust gases. Therefore, such engines are used only in the most performant aerators designed to process large spaces — it is for such units that the combination of high power with battery life is almost mandatory. Note that gasoline models are either verticutters or a combined type (see above); There are no “clean” scarifiers among them, because a rake aerator simply does not require high power.

— Without motor (manual). Aerators that do not have any engine and work at the expense of the user's muscular strength. Usually they are devices in the form of a frame with a working shaft and a handle, with which the operator pushes the structure in front of him. Such units are extremely simple, compact, light and inexpensive, but their functionality is very limited — for example, there is no question of collecting garbage from the treated area.

Working width

The width of the strip processed by the aerator in one pass. The higher this indicator, the faster the device works, the fewer passes will have to be made to process a certain area. On the other hand, a wide grip noticeably affects the dimensions of the entire structure and makes it difficult to work in hard-to-reach places, if not impossible. Therefore, when choosing a model in terms of working width, it is worth considering not only the overall dimensions of the site, but also its configuration and the presence of tight areas — sometimes it is preferable to sacrifice the performance of the aerator for the sake of its manoeuvrability and patency.

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.

Engine size

The volume of the petrol engine installed in the corresponding type of aerator (see "Engine type"). Usually, the larger the engine (with the same type of internal combustion engine, see above) — the higher its power and the more fuel it consumes. In general, this parameter is for reference: manufacturers select it in such a way as to provide the necessary practical characteristics (in particular, the same power).
