Blade Removal And Installation - Honda HRM21PVA Owner's Manual

9. MAINTENANCE
BLADE REMOVAL AND INSTALLATION
When the blade needs sharpening or replacement, take the lawn mower to
an authorized Honda lawn mower dealer. Or, if you have a torque wrench, you
can remove and install the blade yourself. Wear heavy gloves to protect your
hands.
Blade sharpening: To reduce the possibility of weakening the blade, or causing
imbalance or poor cutting performance, have the blade sharpened by an
authorized Honda lawn mower dealer.
Blade replacement: Install a genuine Honda replacement blade or its equivalent.
Use the standard HRM21 low-lift blade for mulching. Use the optional high-
lift HRM21 blade for side-discharge mowing or bagging.

the carburetor side down.

block to prevent the blade from turning when removing nuts.
