• Certain types ofg rass and grass conditions
may require that an area be mulched a sec-
ond time to completely
hide the clippings.
When
doing
a second
cut, mow across
(perpendicular)
to the first cut path.
• Change
your cutting
pattern
from week
to week.
Mow north to south one week
then change
to east to west the next
week.
This will help prevent
matting
and
graining
of the lawn.
