The STIGA SV 415 E electric lawn Scarifier is easy and lightweight to use. It has a 1500W electric motor and two interchangeable operating modes: 44 spring tines for aeration or 20 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 operating depth can be set from -13mm to +4.5mm, and the large 50-litre collector collects the material and moss picked up.
