This high-performance electric scarifier from Germany-based manufacturers Einhell comes with two quick-change cassettes – the first comprises 20 steel blades that will gently but thoroughly pull-out any growth-inhibiting moss and rhizome accumulation; the second is equipped with 48 claws that will open-up the turf so as to better enable water and air to penetrate the root-system, which in turn will promote vigorous, healthy growth. Built to last, the Einhell RG-SA 1433 Electric Scarifier boasts a high-quality impact- and rust-resistant plastic housing, and benefits from a ball-bearing mounted drive-shaft. Its three-stage depth adjustment means you’ll have no trouble managing different soil- and vegetation types; while its large wheels provide the requisite amount of traction without damaging delicate lawn-surfaces. The Einhell RG-SA 1433 is fitted with a handlebar that’s both adjustable and foldable, so it can be adapted to suit gardeners of any height; and it won’t take up much space in the shed or car-boot (a wall-bracket is also featured). Power comes from a high-torque 1400w series-wound motor. This model’s 33cm working-width and 28-litre debris-catcher make it ideal for lawns around 400m2.
