Cutting Leaves:
• After cutting the lawn, ensure that half of the lawn shows through the cut
leaf cover. You may need to make more than one pass over the leaves.
• For light leaf coverage, set all the wheels at the same cutting height setting.
• If there are more than 5 inches (127 mm) of leaves on the lawn, set the
front cutting height 1 or 2 notches higher than the rear cutting height. This
makes it easier to feed the leaves under the lawn mower deck.
• Slow down your mowing speed if the lawn mower does not cut the leave
finely enough.
• If you mow over oak leaves, you can add lime to the grass in the spring to
reduce the acidity of the oak leaves.
