Verticutters

 

— this type of aerator uses a set of vertical blades to work (“vertical cutter” — hence the name). The blades cut through the soil to a depth of several centimeters, making it easier for air and nutrients to penetrate into it, and also stimulate grass growth by cutting the roots. Also, in the process of work, debris is removed from the surface of the earth. Verticutters are especially useful for neglected lawns, although they can also be useful for regularly mowed lawns.
