Cutting Grass

Grass grows at different rates at different times of the
year. In the summer heat, it is best to cut grass at the
2 in. (51 mm), 2-1/2 in. (64 mm), or 3 in. (76 mm)
cutting height settings. Cut only about a third of the
grass blade at a time. Do not cut below the two-inch
(51 mm) setting unless the grass is sparse or it is late
fall when grass growth begins to slow down.
When cutting grass over six inches (15 cm) tall, first
mow at the highest cutting height setting and walk
slower; then mow again at a lower setting for the best
lawn appearance. If the grass is too long and the leaves
clump on top of the lawn, the lawn mower may plug
and cause the engine to stall.
Alternate the mowing direction. This helps disperse
the clippings over the lawn for even fertilization.
If the finished lawn appearance is unsatisfactory, try one
or more of the following:
Sharpen the blade.
Walk at a slower pace while mowing.
Raise the cutting height on your lawn mower.
Cut the grass more frequently.
Overlap cutting swaths instead of cutting a full swath
with each pass.
Set the cutting height on the front wheels one notch
lower than the rear wheels. For example, set the front
wheels at 1- / in. (44 mm) and the rear wheels at
2-1/2 in. (64 mm).
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 five inches (12.7 cm) of leaves
on the lawn, set the front cutting height one or two
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 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.
