Maintaining The Blade - Toro 22291 Operator's Manual

Note:
You can skip this step if you are adjusting
a used belt.

Maintaining the Blade

Always mow with a sharp blade. A sharp blade cuts
cleanly and without tearing or shredding the grass
blades.
1. Shut off the engine and wait for all moving parts
to stop.
2. Disconnect the wire from the spark plug.
3. Drain the fuel from the fuel tank.
4. Tip the machine onto its right side (air cleaner
up) as shown in Figure

Inspecting the Blade
Service Interval: Before each use or daily—Inspect
the mower blades for wear or
damage.
Carefully examine the blade for sharpness and wear,
especially where the flat and the curved parts meet
(Figure 24A). Because sand and abrasive material
can wear away the metal that connects the flat and
curved parts of the blade, check the blade before
using the machine. If you notice a slot or wear
24B and Figure 24C), replace the blade; refer to
Removing the Blade (page

Note:
For the best performance, install a new blade
before the mowing season begins. During the year,
file down any small nicks to maintain the cutting edge.
DANGER
A worn or damaged blade can break, and a
piece of the blade could be thrown toward you
or bystanders, resulting in serious personal
injury or death.
• Inspect the blade periodically for wear or
damage.
• Replace a worn or damaged blade.
Inspecting the Accelerator
Service Interval: Before each use or daily—Inspect
the accelerator for wear or damage.
Carefully examine the accelerator for excessive wear
(Figure 25). Because sand and abrasive material can
wear away the metal (especially in the area shown
as item 2 in Figure 25), check the accelerator before
using the machine. If you notice that a tab on the
accelerator has been worn down to a sharp edge or
there is a crack, replace the accelerator.
