WARNING: Cutting blades are sharp.
Always protect hands by wearing heavy
leather work gloves to grasp blades.
Remove the cutting deck from beneath the
tractor, (refer to DECK REMOVAL in the
MAINTENANCE section of your tractor’s
Operator’s Manual for detailed instructions) then
gently flip the deck over to expose its underside.
Place a block of wood between the center deck
housing baffle and the cutting blade to act as a
stabilizer. See Figure 4.
Use a 15/16" wrench to remove the hex flange
nut that secures the blade to the spindle
assembly.
NOTE: The hex flange nut has a right-handed thread
pattern. Do NOT attempt to force the nut in the
incorrect direction. Doing so may damage the nut and
create a safety hazard.
Figure 4
Install the new blades packed with the bagger. Be
sure to install the blade with the side of the blade
marked ‘‘Bottom’’ (or with a part number stamped
in it) facing the ground when the mower is in the
operating position.
Remount the cutting deck.
IMPORTANT:
Use a torque wrench to tighten the blade
spindle hex flange nut to between 70 foot-pounds and
90 foot-pounds.
Attaching The Discharge Chute
Raise the deck to its highest position by placing
the lift lever in the top notch on the right fender.
While raising the chute deflector on the deck,
angle the front corner of the discharge chute over
the stop assembly and then slide the mounting
rod into the stop assembly. See Figure 5.
Then rotate the discharge chute around the deck
so the front edge fits snugly around the cutting
deck opening.
Fasten the discharge chute in position by hooking
the retainer strap over the retainer clip on the top
rear of the deck.
