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 thoroughly cut
AST
grass clippings, so do not set the height-of-cut so low as to
totally surround the mower in uncut grass. Always try to have
1 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 that 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 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
Clean
Clean clippings and dirt from the underside of the mower
after each use. If grass and dirt build up inside the mower,
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.
