The AL-KO EnergyFlex SF 4036 Cordless Scarifier is the ideal machine for removing thatch and debris from smaller gardens. Its cable-free design makes for flexible working and the battery power offers a clean and quiet alternative to petrol power. All the tools can be operated by a single 36v battery and 36v battery charger (not included). The battery running times for the EnergyFlex 36v range are: 4Ah = 10 minutes and 5Ah = 15 minutes. The Energyflex SF 4036 is fitted with 12 powerful scarifying blades called tines. The robust steel knives remove thatch and debris from the lawn by slicing into the ground. The removed debris is collected into a bag at the rear. The height of the tines can be adjusted via a central lever. The compact 36cm working width make the Energyflex SF 4036 easy to maneuverer.
