Very good Vertikutierleistung and thoughtful details, only the catcher and the Assembly ...

The Einhell GE-SA 1640 is rather a more expensive of its kind. In my last two years a much cheaper device of a large discounter performed his service, but is also now at the end of its life cycle.

For those in a hurry, the summary in advance:

++ Dethatcher & ventilation performance
+ Powerful engine
+ Quick Release for push bar and other good details
+ Durdachte parking position
+ Quite large grass catcher
+ Well-functioning working depth
+ Good cable strain relief
+ Height adjustable push bar
+ Good handling

- Installation (was rectified, see comments)
- Easily processed grassbox
- Quick release must be adjusted for the park position
- Axle guide very delicate

= Not a cheap device, the power and the details make the difference but. Once you overcome the cumbersome installation, the device does a very good job, better than our discounters device and also provides better handling. Now the scarifier must convince only by the durability. I will report here. Until then, I forgive 4 stars, Einhell could make the grass catcher-quality and installation easier.

For exterior:
The Einhell GE SA 1640 looks like the sports car among scarifiers. Class Typically it is made of plastic, which typical matte red has the Einhell. Black elements provide a nice contrast. The plastic looks quite robust even on closer inspection, only the axle guidance looks a little delicate. Since this but does not rotate, but the wheels are rotatably supported, ranging from small plastic bushes well. The wheels are a good size and the instrument has, due to the cutting width ordinary dimensions. It is interesting that Einhell sets for the closures of the bracket completely on quick release, here you notice the difference from low models. Also the push handle has two height position can be easily folded into a perpendicular parking position or folded into itself. He should find his alcove for storage anywhere. The Grasfankkorb is a scarifiers Although quite large, but consists of a very thin-looking mesh fabric, which is supported by a wire frame. This he does not fit the otherwise robust Anumtung the device. Small drawback is taking a closer look, only the axle guide, whose leadership consists of only two small plastic bushes, where small bulges of the axle to prevent lateral displacement, let's see whether this construction keeps the operation.
In addition to the set of blades Einhell supplies as an accessory with a flow system stability. Nice detail, the Allen needed to change has a permanent place on the push handle.

Assembly:
Not the easiest. It is annoying that the threaded rods to the unit that are to receive the push handle tubes and the quick release, are not countered properly inside and can completely slide into the housing. Thus, the quick release can no longer screw and bolt should slide into the housing, must teilzerlegen you there. One should fix when attaching the threaded rod with pliers so that does not happen (apparently the manufacturer has but touched up here, see below standing comment). After the assembly thanks to the quick release went smoothly. For those who do not like to read instructions: When assembling the push bar (multi-part) do not forget to install the part with relief, otherwise you build the temple apart again;). Even the tires mounted and put together the grassbox. Overall, nearly an hour duration by the threaded rods, one of which in the case disappeared, otherwise the assembly would have been done in a quarter of an hour.

Handling:
The scarifier rolls very easily and works sovereignly through the grass. The four large wheels help here (the cheap devices often have only 2 large and two tiny). The height adjustment is very easy to use and locks securely, no ungewolltest adjusted during operation. The working height of the push bar can adapt well thanks height adjustment to the operator. The grass catcher is quite large due to the large cutting width but very quickly full and must be emptied frequently. Once aerated material can be seen in the lawn, it is full. Otherwise, he collects a reliable clippings.
The quick releases are a great solution as well as the different parking positions make it easier to stow. There is nothing to complain about.

Vertikutierleistung:
Very good. The engine is really powerful. In the second level of depth adjustment worked its way through the grass (including quite dry clay), well worth while the appearance of congestion to hinterlassen.Dafür you have the GE-SA 1640 braking intervention during labor, so that he will not rush. The knife set took ordenltich Moss, weeds and grass from the lawn without leaving holes and even in the curves (here patzte our effective device often). The result was a uniformly thinned turf without abnormalities. Smaller stones in the grass made from neither the device nor the set of knives which, the knife showed virtually no wear after the first use.
Also working with the ventilation application goes smoothly and also here will weed taken out of the lawn. The device does not pull here also, allerings as strong as the knife block, which is understandable.
The cleaning after use went smoothly, but that was our old Verticuteermachines also the case.

Volume:
I felt not so loud we expected because Einhell is the volume with 98 db at what is already a house number. In direct comparison, I felt our lawn mower but as loud and the case seems a lot to swallow at noise. If you tilt it, it is much louder.

Conclusion:
A very good device that at the somewhat fortuitous price also has a power increase to our discount model. Many details like the quick release convince the handling is excellent with large wheels and dimensions and the engine operates view powerfully Duch the lawn. Both knife block as well as fan tray can convince it. The result is an evenly auusgedünnter lawn without holes and tidy green waste in the bin. The collector may sound like big, but it's through the cutting width nevertheless fill up fast and can not quite keep up with the good quality appearance of the device. The assembly was not pleasant, so observe oa hint when the threaded rods should be "too short". "Because of the very good but Vertikutierergebnisses, it is enough for 4 stars.
