Petrol or Electric
Medium lawn surfaces can be quickly and easily scarified with an electrically operated device. The AL-KO Combine Care 38 E Comfort is ideally suited for this purpose.
The advantage of a petrol scarifier is its flexible and cable-free use, so it is ideal for a larger garden or difficult to access areas. Its powerful engine is also suitable for working harder grass surfaces.
- I The scarification check Pull a small metal cultivator through your lawn: If you see moss or dead grass residues, then it will be time for scarification - If weeds grow on your lawn, it is a clear sign that your lawn requires attention.
- I How a scarifier works Our scarifiers are equipped with a rotating rollers with steel blades, which penetrate the ground briefly with each turn.
- I Height adjustment Adjust the correct height when scarifying, two to three millimeters of penetration depth should not be exceeded. The collecting container is also important for the collection of moss and thatch.
- I Ground texture The so-called "lawn thatch" grows best on loamy soil, shaded lawns or surfaces, which tend to stagnate. These areas should be more frequently raked and scarified.
- I Correct timing for scarifying The best time to scarify is in spring (April) and autumn (September). After the scarification, the lawn should have time to regenerate. It is advised to mow the lawn before scarifying.
- I Petrol or electric scarifier Electric scarifiers are suitable for medium-sized lawns and have a low noise level and are free of emissions. Petrol scarifiers are also flexible on large surfaces.
Scarifying / Lawn Raking
Almost every garden owner dreams of a beautiful, lush green lawn. But why do some gardens seem like a desiccated desert and the lawn of the neighbouring garden appears in the most beautiful green every year?
Maybe it is because the neighbour regularly scarifies and airs their lawn.
Two processes that are indispensable for a radiant lawn. Ventilation is necessary so that the lawn can absorb enough nutrients and get enough air to breathe again.
Simply explained, scarifying is intensive airing where the lawn surface is slightly cut.
As a result, the soil is loosened and the grass roots can regenerate effectively. Gardeners usually scarify their lawns in spring to refresh them after the cold season.
Scarifying should also be done in the Autumn, especially if the previous winter was particularly hard. So the lawn gets the necessary nutrients again to survive the next winter well.
What exactly does scarification mean?
A scarifier has a rotating cartridge with graded steel blades. These penetrate into the turf and thereby remove lawn thatch, moss and weed remains.
This can be compared to a fixed, close-toothed rake, which penetrates a little way into the ground and, on pulling out, lawn thatch is removed.
Scarifying manually using a rake is an option in smaller gardens, but when it comes to working in larger gardens, or lawns with a lot of thatch and moss, using a motorised scarifier is highly recommended.
No matter what type of device is used, it is important to remove any dead plant parts, as they prevent the light and air from the reaching grass and roots.
It should be noted that only dry, freshly cut lawns should be scarified.
When and how often is the lawn to be raked?
The lawn should not be treated too early - only when the risk of ground frost can be excluded. It is also important that the soil is dry.
In order to achieve a good result when scarifying, the grass should first be cut to about 3 to 4 cm in length. This makes it easier for the scarifying roller to get through the turf.
Depending on the weather, it is possible to scarify the lawn in March or April and also in September, as long as enough ground heat is available.
Scarify once or twice a year is enough. Another tip: The collected lawn debris should not be added to the compost afterwards.
Don't forget the lawn raker.
In addition to scarifying the lawn, it should be raked regularly. Some of our devices are supplied with a spring tined raking roller in addition to the scarifying roller.
In contrast to scarifying, raking can be carried out throughout the year, so that the green lawn stays healthier for longer.
The raking process is almost self-explanatory. The turf is slightly scratched with the raking roller, which is equipped with steel spring tines.
The raking process is important because the lawn surface gradually gets covered over resulting in a reduced amount of oxygen reaching the grass.
In addition, the lawn absorbs the water better after raking and it prevents a so-called waterlogging.
The nutrients can therefore reach the grass roots better.
After lawn raking and scarifying.
After either of the treatments, the grass should be heavily watered and fertilised
A fertiliser has its greatest effect after scarifying, as the nutrients can easily be absorbed and processed. A new lawn seed could be applied for a thicker lawn.
Conclusion: no gardener should miss raking and scarifying. Once or twice a year, a lawn needs a some care, so that it appears full of health and grows efficiently.
If you stick to it, you do not have to be jealous of your neighbour’s garden anymore.
The right scarifier for the job.
When buying a scarifier, attention should be paid to the working width as well as the dual functionality (scarifying and raking).
Nowadays, scarification is occasionally done with a hand-held device, e.g. with a rake or a manual hand scarifier.
This work is laborious, labour intensive and barely manageable for a larger lawn.
The motorised machines make it easier to work and reduce the effort required.
High-quality scarifiers also collect the thatch and the dead plant remains in a collector bag, to further reduce the time it takes to scarify the lawn
Like mowers, scarifiers are also available as petrol or electric powered equipment.
While petrol-powered engines usually have more powerful engines and are therefore geared for larger lawns, electric scarifiers are particularly appealing due to their lower weight.
The biggest drawback with the electric scarifier is the power cable, which must be carried along during the entire work process and routed regularly.

The petrol scarifier is hard to start. Can I use start pilot or similar?
We strongly advise against the use of take-off pilot or similar. Chemicals can in the worst case lead to engine damage. We recommend a review and possibly carburettor cleaning by an AL-KO service partner
Why does the engine run rough and / or cut out immediately after starting?
Check fuel tank contents, top up with petrol if necessary. Some suction carburetors always leave a residue of one to two cm of fuel in the tank. Residues in the fuel or a defective air filter can get dirt into the carburettor. The carburetor may need to be removed and cleaned by an AL-KO service partner .
Which type of fuel can be used in the 4-stroke engine?
It can take any petrol with min. 77 oct. Super Unleaded fuel is 95 oct and can be safely used. Each motor is suitable for E10 - Do not store fuel for over 4 weeks as it will start to go bad if untreated.
Which type of oil can be used in the 4-stroke engine?
An SAE 30 motor oil is recommended, a 5W30 or 10W40 can also be used.
What is the red-green "button" by the height adjustment?
This serves as visual check. Here you can see if the roller is mounted correctly (green) not correctly inserted (red).
Why can't the height adjustment control be turned?
The wheel axle must be relieved for adjustment. Lift the front of the machine up and adjust the height adjustment control.
How do I store the petrol scarifier over winter?
Clean the appliance, change the air filter, spark plug and oil. Store in a dry place.
