Flail Blades

Thatch is the dense layer of clippings, roots and stems
that forms between the soil and the base of the grass.
As thatch builds up, it prevents water, air and fertilizer
from being absorbed into the soil. This causes shallow
root development leading to vulnerability to drought
and frost. Excessive thatch also creates an ideal
environment for insects and lawn diseases. Power-
raking with flail blades removes this thatch layer and
restores your lawn to good health. Flail blades offer
the most aggressive dethatching of all the blades
offered.
