2. Changing a Blade:

connect the spark plug and set the parkng
brake.
b. Jack up the front of the mowing deck about
one foot and block it in that position.

side of the spindle to secure the blade bolt.
d. Remove the hex nut using a 1-1/8" wrench
or socket.
e. Remove the blade assembly from the bolt.
f. The pivot blades are attached to the blade
assembly with grade 8 shoulder bolts. To
remove the blades hold the head of the
bolt with a 3/4” wrench or socket and rem-
move the nut with a 9/16” wrench or
socket. Replace the 9/16” locknuts and the
grade 8 shoulder bolts, and apply locktite
262, or equivalent to the threads.
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.
g. Clean any debris from the blades. Keep
blades sharp and free of build up at all
times.
h. Sharpen the pivot blades as part of the
blade assembly, so that the balance of the
assembly can be checked. 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.
i. Replace any blade with severe nicks or
dents that cannot be removed by filing.
j. Check the balance of the blade assembly
after sharpening by placing it on a blade
balancer. Do not use un-balanced blades.
k. If the blade dips on one end, file stock off
of the cutting surface on that end.
l. To replace the blade reverse the above
process and tighten 1-1/8” nut to 100-120
lb ft. and the 9/16” nuts to 35-40 lb ft.
Note:
Blade assemblies that cannot be eas-
ily balanced—REPLACE. Replace 9/16” lock
nuts if the pivot blades are removed from the
assembly
3. Changing the Blade Drive Belts:
a. Set the parking brake. Remove ignition key
and both spark plug caps.
b. Unscrew the wing nuts from the deck cov-
ers and remove both covers.
c. Using a 1/2" socket breaker bar or socket
rachet insert the male end into the 1/2"
opening in the lower idler arm assembly
and pull the idler arm clockwise. While
holding the idler arm back, loosen the
blade drive belt from the pulley and slide
the belt away from the pulley.
