Removing and Replacing the Blades
To obtain optimum mowing results, you should keep the mower blades sharp and well balanced. Follow
the instructions below to remove, sharpen, and/or replace the blades.
WHEN PERFORMING ANY ADJUSTMENT OR MAINTENANCE, YOU MUST FIRST SHUT OFF THE ENGINE,
SET THE PARKING BRAKE, WAIT FIVE (5) MINUTES TO ALLOW PARTS TO COOL AND DISCONNECT THE
SPARK PLUG WIRE(S), KEEPING IT AWAY FROM THE SPARK PLUG(S).
SHARP EDGES OF BLADES CAN CUT YOU DURING BLADE MAINTENANCE OR ADJUSTMENT. USE GLOVES
OR A RAG WHEN HANDLING BLADES TO PREVENT INJURIES.
Tools and Supplies Needed:
•
15/16" Wrench or Socket
•
(2) 1/2" Wrench
• Pliers
•
Gloves or a Rag
•
Block of wood to brace the Blade
1. Remove the Deck from the chassis following the
instructions on page 33. Invert the Deck as shown
in
Figure 16 .
2. Place a short piece of 2 x 4 lumber between the side
of the Deck and the Blade to “lock” it in position
(Figure 16). Using a 15/16" Wrench, remove the
Blade attaching Bolts and Washers from the
Spindle. Remove the Blade and repeat this step for
the other two (2) Blades.
3. File or grind the Blades evenly. Take care to retain
the angle of the original cutting edge.
NOTE: You should always check the Blade balance.
Inexpensive blade balancers are available at most
hardware stores.
4. Reinstall the Blades with the Lift (turned up) portion
(Figure 17) facing up. Tighten the Blade attaching
Bolts securely.
NOTE: Be sure to seat the Blade completely over the small
ridge in the Spindle Hub before tightening the Bolt.
5. Reinstall the Deck following the instructions on
