Dethatching Information

Thatch is a normal buildup of grass and leaf clippings around the base of grass stems. Excessive thatch
prevents air, water and nutrients from reaching the root system, increasing the probability of lawn disease
from mold spore and insects. When excessive thatch is removed, air, water, nutrients and pesticides are
allowed to keep your lawn healthy, promoting denser, greener grass. In most areas some thatch
approximately 6-13 mm (0.25 - 0.50 in.) is healthy for soil water retention. Never remove all thatch from your
lawn. Contact your local government agriculture agency for best dethatching practice for your lawn type and
area.
Dethatching is recommended in early spring and late summer to allow grass to fill in low density areas of
your lawn. Dethatching should also be performed at regular intervals throughout spring and summer.
Dethatching is not recommended for grasses that have above ground root systems such as St. Augustine,
Floratam, Persley, or Zoysia varieties. The dethatcher tines will damage delicate interconnected root
systems of these grass varieties.

Dethatching Operation

1. Operate dethatcher in straight rows changing direction from row
to row as shown. If thatch is very dense a second dethatching
operation may be required, and should be performed 90° to the
original pattern to assure best results.
2. Hold unit in a comfortable position engage throttle trigger to full
and allow dethatcher tines to "pull forward" over the ground. For
heavy thatch removal gently pull back against dethatching
rotation, to allow the tines to fully penetrate and remove thatch.
Do not remove grass guide attached to the gear housing to achieve
deeper tine engagement. The guide prevents tines from penetrating too deeply into the ground which can
cause the dethatcher to bounce during operation, and cause uneven thatch removal.
