Jack up the front of the mowing deck about 
one foot and block it in that position.

c.

Wrap a rag around one end of the blade 
and grasp it to prevent it from turning, or 
secure the blade by placing a block of 
wood between the blade and the deck 
housing.

WARNING:

Never mow with dull blades! Blades that are
bent should be replaced! The cutting blades
are sharp and can cause severe injury. Wrap
the cutting surface of the blade with a rag to
avoid injury.

a. Set the parking brake.
b.

Clean any debris from the blades. Keep 
blades sharp and free of build up at all 
times.

c.

Sharpen blades evenly at the original 30° 
angle to maintain balanced cutting blades. 
Do not sharpen the underside of the 
blades. Use a electric blade sharpener, a 
conventional electric grinder or a hand file 
to sharpen the blades.

d. Replace any blade with severe nicks or 

dents that cannot be removed by filing.

e.

Check the balance of the blade after 
sharpening by placing it on a blade bal-
ancer. Do not use un-balanced blades.

f.

If the blade dips on one end, file stock off 
of the cutting surface on that end.

Note:

 

Blades that cannot be easily bal-

anced—REPLACE.
