Operating Tips

Fast Throttle Setting
For best mowing and maximum air circulation, operate
the engine at the fast throttle position. Air is required
to thoroughly cut grass clippings, so do not set the
height-of-cut so low as to totally surround the mower
by uncut grass. Always try to have one side of the
mower free from uncut grass, which allows air to be
drawn into the mower.
Cutting a Lawn for the First Time
Cut grass slightly longer than normal to ensure the
cutting height of the mower does not scalp any uneven
ground. However, the cutting height used in the past
is generally the best one to use. When cutting grass
longer than 15.2 cm (6 inches) tall, you may want to
cut the lawn twice to ensure an acceptable quality of
cut.
Cut 1/3 of the Grass Blade
It is best to cut only about 1/3 of the grass blade.
Cutting more than that is not recommended unless
grass is sparse, or it is late fall when grass grows
more slowly.
Mowing Direction
Alternate mowing direction to keep the grass standing
straight. This also helps disperse clippings which
enhances decomposition and fertilization.
Mow at Correct Intervals
Normally, mow every four days. But remember,
grass grows at different rates at different times. So
to maintain the same cutting height, which is a good
practice, mow more often in early spring. As the
grass growth rate slows in mid summer, mow less
frequently. If you cannot mow for an extended period,
first mow at a high cutting height; then mow again two
days later at a lower height setting.
Cutting Speed
To improve cut quality, use a slower ground speed
in certain conditions.
Avoid Cutting Too Low
If the cutting width of the mower is wider than the
mower you previously used, raise the cutting height to
ensure that uneven turf is not cut too short.
Long Grass
If the grass is ever allowed to grow slightly longer than
normal, or if it contains a high degree of moisture,
raise the cutting height higher than usual and cut the
grass at this setting. Then cut the grass again using
the lower, normal setting.
When Stopping
If you must stop the forward motion of the machine
while mowing, a clump of grass clippings may drop
onto your lawn. To avoid this, move onto a previously
cut area with the blades engaged.
Keep the Underside of the Mower
Clean
Clean clippings and dirt from the underside of the
mower after each use. If grass and dirt buildup inside
the mower, cutting quality will eventually become
unsatisfactory.
Blade Maintenance
Maintain a sharp blade throughout the cutting season
because a sharp blade cuts cleanly without tearing or
shredding the grass blades. Tearing and shredding
turns grass brown at the edges, which slows growth
and increases the chance of disease. Check the
cutter blades daily for sharpness, and for any wear or
damage. File down any nicks and sharpen the blades
as necessary. If a blade is damaged or worn, replace
it immediately with a genuine Toro replacement blade.
