• For light leaf coverage, set all the wheels at the same
cutting height setting.
• If there are more than 5 inches (12.7 cm) 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 mower
housing.
• Slow down your mowing speed if the mower does
not cut the leaves 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.
