7.4  CUTTING BLADE SERVICE 

Check blades after each use for signs of excessive 
wear and damage.  See Figure 7.4 for blade wear limits. 
 

 

 

 
1.  Use the following chart for ordering replacement 

Blades for the 36” & 48” Mowing Decks. 

 

 
7.4.1.  BLADE REMOVAL AND SHARPENING 
1.  Place the mower on a smooth level surface, turn 

engine OFF, remove key, disconnect Spark Plug Wire 
from Spark Plug and secure Wire away from Plug. 

2. Remove 

blades. 

 
 
IMPORTANT: Note the number of blade spacers that 
are under the Blade Mounting Nuts and on the Spindle 
side of the Blade. 
 
 
3.  Clean and inspect each Blade for excessive wear and 

damage. Refer to Section “BLADE WEAR LIMITS”. 

4.  Refer to the STANDARD REPLACEMENT BLADE 

chart above for correct SNAPPER Replacement Blades. 

5.  Should Blades be in acceptable condition, sharpen at 

22 to 28 degrees. DO NOT sharpen beyond original 
cutting edge.  See Figure 7.5. 

6.  Balance each Blade after sharpening by grinding 

metal from the heavy end of the Blade. 

7.  Place the Blade mounting bolt through bevel washer 

and into Blade and place Blade Spacers over Bolt.  
Make certain each Blade is installed with the same 
amount of Spacers. 

 

 
 

 

 
NOTE: When sharpening Blades, leave 1/64” 
untouched. Razor sharp Blades dull quicker and 
damage easier. Commercial balancers are available 
and should be used in accordance with the 
manufacturers instructions. 
 
8.  Install Blade Mounting Bolt with spacers and Blade 

into spindle. 

9.  Install an equal amount of Blade Spacers onto each 

blade mounting bolt. 

10. Install the Blade Mounting Nut on each Blade 

Mounting Bolt.  See Figure 7.6. 

11. Torque each Blade Mounting Bolt and Nut to 60 to 

75 ft. lbs of torque.
