• 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.
