SECTION 11 DETHATCHER (Optional)
Dethatcher Safety Information
1. Operate your dethatcher only when there is
adequate light.
2. Remove all debris such as wire, bottles, cans,
sticks, and stones from the area to be
dethatched.
3. Always remove the spark plug wire and
disconnect the battery on electric start mowers
before servicing your mower dethatcher.
4. Before each use, check to make sure all
fasteners are tight, tines are functioning properly,
and safety wires are
in place.
5. Reduce speed and cautiously dethatch any area
(rough ground) of the turf that may have hidden
hazards.
6.
Do not leave your mower running while
unattended stop
the engine and remove the
ignition key if
so equipped.
7. Make a visual check of the dethatcher stop
bracket
it must be in the proper location and
tight!
8. Store dethatcher on the floor to prevent any
injuries from occurring.
Dethatcher Operation
When dethatching, an overlap
or cross-hatch pattern
is recommended. While all lawns are different, the ideal
amount of thatch
left on the lawn would be about 3 mm
(1/8') thick. Very dense lawns generally require more
frequent dethatching than do less dense lawns.
Grass should be less than 7.5 cm
(3") tall for proper
tine action. The tines should deflect back and
then
independently 'flip' the thatch up and forward. If the
tines tend to drag, raise them a little and recheck the
'flipping' action. Adjust the tine tray up
or down as
necessary for proper action.
