The STIGA SV 213 E lawn aerator and Scarifier is powered by a 1300W electric motor and has two interchangeable kits: 36 spring tines for aeration and 16 blades for scarifying. The blades will create grooves, which helps oxygen and water to reach the grass roots so they can grow better. The spring tines work on the surface of the ground, removing a layer of dead grass, mould and organic matter found at the base of the blades of grass. This helps the soil to absorb water better and encourages healthier and stronger grass growth. The ideal times for treating the ground are spring and autumn. The working depth can be set from -6mm and +4mm and the 40-litre collector collects the material and moss picked up.
