The RYOBI 36V Brushless Scarifier 4.0Ah Kit is for lawn enthusiasts who want to promote a healthier, fuller looking lawn in their garden. The 36V Brushless Scarifier is designed to effectively remove layers of dead grass (thatch) and moss that can deprive lawn of the essential water and nutrients it needs for growth. Equipped with stainless steel blades, this Scarifier removes layers of debris that would usually prevent rainwater from draining deep into the soil where the grass needs it the most for nutrients. Switch between four different working depths to ensure all the moss and thatch is removed and captured in the attached debris catcher. This Scarifier has a powerful brushless motor compatible with all RYOBI 36V batteries. For easy storage, the Scarifier’s handles fold down to take up less room in the garage or shed. This kit includes a 36V Brushless Scarifier, Scarifier Drum Attachment, Debris Catcher, Safety Key, 36V 4.0Ah battery, and 36V 1.7A Charger.
