Replacing The Blade; Cleaning The Mower - Toro 20792 Operator's Manual

Replacing the Blade

Important: You will need a torque wrench to install
the blade properly. If you do not have a torque wrench
or are uncomfortable performing this procedure,
contact an Authorized Service Dealer.
Examine the blade whenever you run out of gasoline. If the
blade is damaged or cracked, replace it immediately. If the
blade edge is dull or nicked, have it sharpened or replace it.
The blade is sharp; contacting the blade can result
in serious personal injury.
Wear gloves when servicing the blade.
1. Disconnect the spark plug wire from the spark plug.
Refer to Preparing for Maintenance.
2. Tip the mower onto its side with the air filter up.
3. Use a block a wood to hold the blade steady (Figure 38).
Figure 38
4. Remove the blade, saving all mounting hardware.
5. Install the new blade and all mounting hardware.
Important: Position the curved ends of the blade
to point toward the mower housing.
6. Use a torque wrench to tighten the blade bolt to
60 ft-lb (82 N⋅m).
Important: A bolt torqued to 60 ft-lb (82 N⋅m)
is very tight. While holding the blade with a block
of wood, put your weight behind the ratchet or
wrench and tighten the bolt securely. This bolt is
very difficult to overtighten.
