The Best Electric Scarifiers
1. Bosch AVR 1100
The Bosch AVR 1100 electric scarifier with bin remains my favorite at the moment. Thanks to its 4 different height settings, you will hardly find a better way to aerate your lawn by getting rid of moss and weeds.
The Bosch 060088A100 electric scarifier is devilishly efficient with its solid stainless steel blades. Quiet and easy to handle, it is equipped with a 50-liter container allowing you to work on gardens with a large surface area.
When it is time to store it, it does not take up much space since its handlebars are fully foldable. In short, if you want to opt for quality, you will not be disappointed by the AVR 1100 model from the famous German brand known for its reliability. The opinions of private and professional gardeners are positive and the device also has a 2-year warranty.
2. AL-KO Combi Care 38E Comfort Electric Aerator/Scarifier
In terms of price / quality ratio, the AL-KO Combi Care 38 E Comfort electric scarifier is an interesting alternative. If the brand is a little less well-known in France, it is a German manufacturer specializing in gardening tools renowned on the other side of the border just like Bosch!
The AL-KO Combi Care 38 E Comfort model also removes moss easily for a garden of up to 800m². It plugs into the mains, weighs 14kg and comes with a 55-liter grass collector.
With its 1300 Watts motor and 5 depth settings, AL-Ko offers a powerful and easy-to-use device. User reviews on the internet, especially on gardening forums, are again very good. Finally, I only blame it for its weight of almost 14kg which can be annoying if there is a steep climb between your garage and your garden.
3. Black & Decker GD300 Lawnraker
For small budgets, the Black + Decker GD300 electric scarifier can be more than sufficient for a garden of less than 300m². Ultra light (7kg) and easy to handle, this defoamer does the job you ask of it without breaking the bank!
Unlike the 2 previous models, you will need a little time during the first pass if your lawn is covered with moss. It is a model designed for individuals to aerate the lawn in the spring and then in the fall.
The Black + Decker GD300 is a reliable device guaranteed for 2 years by the American manufacturer. Note however that the wire is very short and an extension will be necessary in parallel even for a small garden.
How Does An Electric Scarifier Work?
An electric scarifier is a gardening tool designed to remove dead moss and other cut grass debris. It is a 4-wheel device, like a lawn mower , with a series of blades underneath that rotate on the lawn to gently remove thatch (layer of dead grass and other organic matter), moss and weeds .
The cutting action also helps aerate the soil, making it healthier, weed-free and more durable. Failure to scarify your lawn and respect other maintenance work can have devastating consequences.
If dead grass clippings and moss are left on the surface of the lawn (beyond a reasonable amount), it can prevent rainwater from draining deep below the ground where it is most. no longer needed. Excess moisture can also promote the growth of mosses, which makes the problem worse.
Manual, Electric Or Thermal Scarifier?
The choice between a hand-held, electric and thermal scarifier should be made mainly according to the surface of your garden.
For a small garden up to 30 m², a manual rake-shaped scarifier is recommended. It is easy to use and only costs around thirty dollars.
For an area between 30 and 800m², the electric scarifier remains the ideal compromise. This must be connected to the mains and have a sufficiently large tank according to the area to be defoamed.
Finally, for very large gardens beyond 800m², a thermal model will be necessary in order to save time. Cordless thanks to a gasoline engine, it is generally more powerful and reserved for professionals.
How To Choose The Right Electric Scarifier?
If all electric scarifiers look the same at first glance, here are some important criteria allowing to decide between 2 models in order to make the right choice.
First of all, a quality electric scarifier must have a sufficiently powerful motor. Indeed, the device must be able to turn its blades even in difficult areas. I therefore advise you to check that the power is at least 1000 Watts (500 Watts may be sufficient for a small garden).
Number of positions
Depending on the configuration of your land, it is often useful to go through several times with an electric scarifier, starting with the highest position. Thus, the more the model offers different positions, the more the scarification will tend to be effective.
In order not to have to empty the grass collector every 5 minutes, it is important that an electric scarifier has a bin with sufficient liters (unit of volume used). Most mid-range and top-of-the-range models are sold with a capacity of at least 50 liters, ideal for large gardens.
Weight and ergonomics
The weight of an electric scarifier can vary by several kilograms between different models which can impact ease of use. Even if it is only used once or twice a year, a light device is more pleasant to use, especially if you have a large garden. Likewise, check the opinions of users concerning general ergonomics because not all devices are necessarily well designed!
As with any gardening device, the choice of brand remains crucial in order to avoid any unpleasant surprises. German brands stand out in this sector thanks to the robustness of their electric scarifiers offered, not to mention reliability over time.
When And How Often To Use An Electric Scarifier In The Year?
The ideal time to scarify your lawn can vary depending on the area you are in and the weather. Usually the best time is when turf growth is most prolific. This growing season normally takes place in the fall or late spring.
Be careful to choose an ideal time period. If you scarify when there has been heavy rain or extreme conditions like drought, you could be doing more damage than good. This is because the grass will not be able to grow back for a long time after you have scarified it.
As for the frequency, once a year is normally sufficient, once every 6 months if your lawn is in poor condition with a lot of moss. Scarifying your lawn can take a toll on the roots, so you should always use caution.
How To Use The Electric Scarifier In Your Garden?
Before you start scarifying your lawn, you must first remove large weeds by removing them with a trowel or small garden fork. You can also apply an anti-moss product to the main moss spots on your lawn about 10 days before the passage. This will prevent the moss that the scarifier removes from spreading around your garden.
Next, run your lawn mower on a low setting so that the moss and thatch are exposed. In the process, use the scarifier as you would a lawn mower, following the same lines you created when mowing the lawn.
First set the scarifier blades in the up position to avoid damaging your lawn. Then make a few passes on the lawn, at slightly different angles, lowering the blades slightly with each pass.
As you scarify the lawn, the moss and thatch will be removed and the blades will trim the grass to promote thicker growth. Aeration of the lawn will help prevent future moss growth by improving drainage. It will also allow water, nutrients and air to enter the soil to nourish the roots and improve grass growth.
Finally, after you are done scarifying your lawn, there may be bare spots where the moss and thatch has grown. Overseeding involves sowing new grass seeds on your lawn to fill in empty spaces and encourage thicker grass growth. This is a key process after you have scarified and aerated your lawn.
