IMPORTANT INFORMATION
Clear the lawn of any debris.
Clearly mark rocks and other fixed
objects.
Be especially sure to check for hidden
electrical cables or similar in the surface
of the lawn.
OPERATION
Before you start
• Mow the lawn 1/2" shorter than normal.
• Allow the lawn to dry. Wet conditions can
cause extensive damage to healthy grass.
• To engage the clutch in heavy thatch, bear
down on the handle and raise the front
wheels slightly. Hold the clutch engaged
against the handle and carefully lower the
machine into the turf.
• Do a small test area at a slow walking
pace.
• If the engine speed drops excessively, the
depth setting is too deep. Turn the depth
knob clockwise.
• If the machine pulls forward and bucks
roughly, the depth setting is too deep.
Check for stones or fixed objects in the
lawn. Then turn the depth knob clockwise.
• Lock the depth knob with the depth lock
after adjusting settings.
Finishing
• Remove all extracted thatch from the
grass and compost/dispose of properly.
• Other methods for improving your lawn
may include aeration and fertilization.

FLAIL BLADES OR SPRING TINES:
• Flail Blades or Spring Tines: Set blade
or tine depth so that the blades or tines
just touch on a flat surface such as a
sidewalk or driveway.
• Delta Blades: Set blades to penetrate
the soil to a depth of 1/8" to 1/4" with a
maximum penetration of 1/2". Check your
seed bag for the manufacture’s
recommended depth of application
• Lawns with deep thatch exceeding 2 cm
may be best dethatched in two
treatments (spring and fall) to avoid
major shock to an older lawn.
