Convert the lawn mower
Your lawn mower was shipped ready to be used in
mulching mode.
The mulching mode will recut the grass clippings many
times, which will reduce the clippings in size so that as
they fall onto the lawn they will disperse into the grass and
not be noticed. In addition, the mulched grass will
biodegrade quickly to provide nutrients for the lawn.
Use rear bagging to collect the grass clippings within the
grass catcher.
WARNING! Do not run your lawn mower
!
without rear door closed or approved
