MULCHING MOWING TIPS
For best performance,
keep the mower housing free of built-up
grass and trash. Clean after each use. See CLEANING"
in the
maintenance section of this manual.
Avoid cutting the lawn when it is wet. Wet grass tends to form
clumps and they interfere with the mulching action. The best time
to mow your lawn is in the early afternoon. At this time the grass
is dried and the newly cut area will not be exposed to the direct sun.
For best results, adjust the lawn mower cutting height so that the
lawn mower cuts off only the top one third of the grass blades. Ifthe
lawn is overgrown it will be necessary to increase the cutting height
to reduce the pushing effect and reduce overloading the motor. For
extremely heavy mulching make narrower cuts and mow slowly.
Certain types of grass and grass conditions may require that an
area be mulched a second time to completely hide the clippings.
When doing a second cut, mow across or perpendicular to the first
cut path. DO NOT MOW PERPENDICULAR
TO THE FIRST
PATH IF IT WOULD CAUSE MOWING ACROSS A HILL.
Change your cutting pattern from week to week. Mow north to
south one week and east to west the next week This will help
prevent matting and graining of the lawn.
