 1.  Blades should be sharp and free of nicks and 

dents. If not, sharpen blades as described in 
following steps.

 2.  To remove blade for sharpening, use a 1” wrench 

on the flats of the spindle shaft while removing the 
blade mounting bolt with a 15/16” wrench (Figure 
26).

 3.  Use a file to sharpen blade to fine edge. Remove 

all nicks and dents in blade edge. If blade is 
severely damaged, it should be replaced.

 4.  Balance the blade as shown in Figure 27. Center 

the blade’s hole on a nail lubricated with a drop of 
oil. A balanced blade will remain level.

 5.  Reinstall each blade with the tabs pointing up 

toward deck as shown in Figure 28.  Secure with 
a bolt and flat washer and torque bolts to 70 ft.lbs.
