Arnold 21 in. and 22 in. Universal Power Rake Blade with 5-Point Star Adaptor for Walk Behind Mowers

The Arnold 6-in-1 blade dethatches, bags, rakes, scalps, mulches and cuts. The reason is thatch can keep water and air from reaching the soil and, if left untreated, can create an environment that harbors pests and diseases. Dethatching removes those layers of dead grass, roots and debris matted between the soil and the growing grass, keeping the grass greener and healthier while minimizing the chance of disease.
