Installing The Blade - Toro LAWN-BOY 20041 Manual

Inspecting and Sharpening the Blade
Installing the Blade
,
Install the blade onto the spindle or blade driver. If
the blade has curved tips (sails), they should be
pointing towards the mower housing (Figure 9). If
the bolt or nut uses a nylon patch or similar lock
feature, it should be replaced every third time it
has been removed. The patch will wear out with
use. If a lock washer is used, inspect it for damage
and replace if warranted.
