MULCHING MOWING TIPS
IMPORTANT: FOR BEST PERFORMANCE, KEEP MOWER
HOUSING FREE OF BUILT-UP GRASS AND TRASH. CLEAN
AFTER EACH USE.
• The spe cial mulch blades will recut the grass clip pings
many times and reduce them in size so that as they fall
onto the lawn they will disperse into the grass and not
be noticed. Also, the mulched grass will biodegrade
quick ly to provide nutrients for the lawn. Always mulch
with your highest engine (blade) speed as this will pro vide the best recutting action of the blades.
• Avoid cutting your lawn when it is wet. Wet grass tends
to form clumps and interferes with the mulch ing action.
The best time to mow your lawn is the early afternoon.
At this time the grass has dried and the newly cut area
will not be exposed to the direct sun.
• For best results, adjust the mower cutting height so
that the mower cuts off only the top one-third of the
grass blades. For ex tremely heavy mulch ing, re duce
your width of cut and mow slow ly.
• Certain types of grass and grass con di tions may re quire
that an area be mulched a second time to com pletely
hide the clippings. When doing a sec ond cut, mow
across or perpendicular to the fi rst 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.
