Note:

 

There is a certain amount of spring 

tension due to the weight of the deck. When 
removing the lift linkage from the deck the ten-
sion of the springs will go from the deck to the 
lift handle. Not capturing the lift handle while 
removing the lift linkage from the deck will 
cause it to snap back.

d.

from the deck and (2) from the front of the 
mower. Remove the cotter pins on the left 
and right rear side of the cutter deck (2); 
remove the cotterpins on the left and right 
front side of the cutter deck (2); and 
remove the cotter pins on the front of the 
mower (2).

2.

Changing a Blade:

a.

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

b.

To prevent the blade from turning, secure 
the blade by placing by placing a block of 
wood between the blade and the deck 
housing.

c.

Use a 1-1/8" socket wrench on the pulley 
side of the spindle to secure.

process and tighten nut to 100-120 ft. lb.

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. apply 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.

a.

Apply the parking brake. Remove ignition 

key and both spark plug boots.
