1.
Removing the Mower Deck:
a. Apply the parking brake. Remove ignition
key and both spark plug caps.
b. Lower the cutter deck to the lowest setting
and capture the lift pedal by placing the
height of cut clevis pin into the "Lock" hole.
c. Remove tension of the PTO belt by moving
the belt tensioning spring.
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
deck lift pedal. Not capturing the deck lift
pedal while removing the lift linkage from the
deck will cause it to snap back.
d. Detach the mower drive belt.
e. Remove the four hair pins from the right
and left side of the mower. Shift the deck
forward until the Trailing Link is free and
you are able to remove the deck.
f.
Turn front caster wheels outward.
g. To install reverse the process
2.
Changing a Blade:
a. Remove the key from the ignition and dis-
connect the spark plugs.
b. 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.
d. Use a 1-1/8" socket wrench on the pulley
side of the spindle bolt.
e. Remove the hex nut at the blade using a 1-
1/8" wrench.
f.
Remove the blade.
g. To replace the blade reverse the above
process and tighten nut to 100-120 lb ft.
Note:
Add a small amount of multi-purpose
grease to the bolt threads to avoid corrosion
and galvenic action
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.
3.
Sharpening the Blade:
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.
4.
Changing the Blade Drive Belts:
a. Set the parking brake. Remove ignition key
and both spark plug caps.
b. Unscrew the nuts from the deck covers
and remove both covers.
c. Using a 1/2" socket breaker bar or socket
ratchet insert the drive end into the 1/2"
square opening in the lower idler arm
assembly and push the idler arm counter-
clockwise. While holding the idler arm
back, loosen the blade drive belt from the
pulley and slide the belt away from the pul-
ley.
d. Remove tension of the PTO belt by moving
the belt tensioning rod. Loosen the belt
retaining bolt.
e. Pull the tensioner pulley away from the belt
and remove the PTO belt then remove the
blade drive belt.
f.
Reverse the process to install the belt.
Note:
When replacing belts do not over-
tighten. Adjust the idler pulley so that a ten-
pound pull with a spring scale between two
pulleys deflects the belt about 1/2".
