A scarifier, sometimes called a dethatcher, removes the build-up of dead grass and weeds that forms on top of lawns and prevents moisture from reaching the roots. With a powerful Briggs & Stratton® 163cc engine and a wide 40 cm cutting width, this Scarifier helps remove debris so that your lawn gets the nourishment it needs. The large 50 litre grass bag reduces stops for emptying, and the handle folds for compact storage. Most lawns benefit from scarification twice a year.
