Operating Tips

Using the Fast Throttle Setting
For best mowing and maximum air circulation, operate
the engine at the F throttle position. Air is required to
AST
thoroughly cut grass clippings, so do not set the height-of-cut
setting so low as to totally surround the mower by 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, 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 1/3 of the grass blade. Do not
cut more than that unless the grass is sparse or it is late fall,
when grass grows more slowly.
Alternating the Mowing Direction
Alternate 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. So to
maintain the same cutting height, mow more often in early
spring. As the grass growth rate slows in midsummer, 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.
Adjusting the Cutting Speed
To improve cut quality, use a slower ground speed in certain
conditions.
Avoiding 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.
Cutting 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.
Stopping the Machine
If you 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.
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
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.
