With cordless garden tools colonising garden sheds around the country, AL-KO has added the SF 4036 battery-powered lawn scarifier to its EnergyFlex range.

With its sleek shape and effective results, AL-KO's lithium-ion battery technology means faster, cleaner, cheaper and quieter moss and thatch removal with this quality cordless lawn scarifier. A cord-free alternative to an electric lawn scarifier and hassle-free compared to petrol models.

The AL-KO SF 4036 is powered by an interchangeable and fully rechargeable 40 volt lithium-ion battery which delivers around 10 minutes operating time on a single 90 minute charge of a 4Ah battery. If you want more, a 5Ah battery will give you 15 minutes on a 120 minute charge.

Equipped with 12 scarifying blades, the SF 4036 will easily remove thatch from the grass roots, whilst the optional lawn raking drum can be used for lighter raking of the lawn. The working height can be conveniently changed centrally with a single hand movement.


The EnergyFlex series of varied battery-powered machines for cable free and effortless garden enjoyment

The AL-KO EnergyFlex platform comprises three lawn mowers, a lawn scarifier and an array of different hand tools so you have everything you need for your garden.

Suitable for use with all EnergyFlex tools, a battery and charger are supplied with the lawn mowers.The same battery can be used for operation of the bare tools, and an additional 4Ah or 5Ah battery and charger can also be purchased separately.
