Section 4: Operation
Match Speed
To Terrain and Conditions
Adjust the speed to grass conditions and
terrain. Use Low and Medium speeds for
normal mowing conditions. You'll get
better results at slower speeds, especially
if the grass is tall or lush. Use High speed
to transport the mower or when grass
conditions are light and appearance is not
as important.
Keep Mower Blade Sharp
A sharp blade cuts the grass cleanly,
resulting in a smooth, evenly cut lawn. A
dull blade tears at the grass and will fray
the tips so that they dry out quickly
resulting in a dull, brown-looking lawn.
See Blade Sharpening and Balancing in
Section 5 of this manual for more infor-
mation.

Mulching Leaves
A light covering of leaves can be effec-
tively mulched into the turf. As the leaves
decompose, they provide valuable organic
matter and minerals to the soil.
To ensure effective mulching, be sure the
leaves are dry. Use a slow travel speed
and don't try to mulch a deep layer of
leaves.
NOTE: Oak leaves are acidic and may
affect the soil pH level when mulched. A
pH soil test should be used if oak leaves
are abundant on your property.
