Side-discharging the Clippings

Use the side discharge for cutting very tall grass.
If the bag is on the mower, remove it and insert the
mulch plug (refer to Removing the Grass Bag) before
side-discharging the clippings.
Important: The mower has a safety switch that
prevents you from starting the mower unless you
first install the mulch plug securely on the mower
(refer to Mulching the Clippings).

Operating Tips

General Mowing Tips
• Clear the area of sticks, stones, wire, branches, and
other debris that the blade could hit.
• Avoid striking solid objects with the blade. Never
deliberately mow over any object.
• If the mower strikes an object or starts to vibrate,
immediately stop the engine, disconnect the wire
from the spark plug, and examine the mower for
damage.
• For best performance, install a new blade before the
cutting season begins.
• Replace the blade when necessary with a Toro
replacement blade.

Cutting Grass

• Cut only about a third of the grass blade at a time.
Do not cut below the 2 inch (51 mm) setting unless
the grass is sparse or it is late fall when grass growth
begins to slow down. Refer to Adjusting the Cutting
Height.
• When cutting grass over 6 inches (15 cm) tall, mow
at the highest cutting height setting and walk slower;
then mow again at a lower setting for the best lawn
appearance. If the grass is too long, the mower may
plug and cause the engine to stall.
• Mow only dry grass or leaves. Wet grass and leaves
tend to clump on the yard and can cause the mower
to plug or the engine to stall.
