Comparison Einhell GC-SC 2240 P vs HECHT 5654

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.

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.

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.

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.

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).

In accordance with the name, models with this feature move themselves during operation, which relieves the operator of the need to push the unit in front of him and facilitates work. This is especially important for high-performance aerators that have significant weight. On the other hand, self-propelled devices are noticeably more expensive than non-self-propelled ones, consume more fuel / energy and require more powerful engines — after all, part of the power must be directed to ensure movement, while in non-self-propelled structures it can all be used on the working shaft.

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.

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).

Aerator engine power expressed in horsepower (hp). In the case of aerators, this unit is used only for models with gasoline engines (see "Engine type"). Note that some time ago, the designation of power in horsepower was standard for internal combustion engines, but now watts are increasingly used for this; so hp is used more as a tribute to tradition than as an urgent need, and most often these data are duplicated in watts. However, even if there is no such duplication, some units can be easily converted to others: 1 hp. approximately corresponds to 735 watts. For more information about the value of engine power, see the paragraph of the same name below.
