Operating Tips
Using the Fast Throttle Setting
For best mowing and maximum air circulation, operate
the engine at the F position. Air is required to
AST
thoroughly cut grass clippings, so do not set the
height-of-cut so low as to totally surround the mower
deck in uncut grass. Always try to have 1 side of the
mower deck free from uncut grass, which allows air
to be drawn into the mower deck.
Cutting a Lawn for the First Time
Cut grass slightly longer than normal to ensure that
the cutting height of the mower deck 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 cm (6 inches) tall,
you may want to cut the lawn twice to ensure an
acceptable quality of cut.
Cutting a Third of the Grass Blade
It is best to cut only about a third 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.

Alternating the Mowing Direction
Alternate the mowing direction to keep the grass
standing straight. This also helps disperse clippings,
which enhances decomposition and fertilization.
Mowing at Correct Intervals
Grass grows at different rates at different times of
the year. To maintain the same cutting height, 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 2 days later at a
lower height setting.
Using a Slower Cutting Speed
To improve cut quality, use a slower ground speed
in certain conditions.
Avoiding Cutting Too Low
When mowing uneven turf, raise the cutting height
to avoid scalping the turf.
Stopping the Machine
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 or you
can disengage the mower deck while moving forward.
Keeping the Underside of the
Mower Deck Clean
Clean clippings and dirt from the underside of the
mower deck after each use. If grass and dirt build up
inside the mower deck, cutting quality will eventually
become unsatisfactory.
Maintaining the Blade(s)
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
mower blades after each use 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.
