Use a 15/16” wrench to remove the hex flange nut that secures
the blades to the blade spindle assemblies. See Figure 4-14.
WARNING:
The hex flange nut has a right-handed
thread pattern. Do not attempt to force the nut in
wrong direction; it may damage the nut and create a
safety hazard.
4.
Place a new blade on each spindle so that side of the blade
with part number faces the ground when the mower is in
the operating position.
5.
Secure with the hex flange nut removed earlier. Use a
torque wrench to tighten the hex flange nut between 70 to
90 foot-pounds.
6.
Move the wood block to either the left or right blade for
stabilization and remove and replace the center blade so
that side of the blade with part number faces the ground
when the mower is in the operating position.
Installing the Deck Baffle
Note:
If the deck is still flipped upside down with the blades
exposed, it may be easiest to flip the deck back over to complete the
following installation of the deck baffle and chute stop bracket.
1.
Remove two of the self-tapping deck screws on the front
right side of your deck.
2.
Install the deck baffle included with the loose parts to the
underside of the mowing deck using two 710-04666 hex
bolts and 912-3027 flange lock nuts from hardware pack
689-00329, as shown in Figure 4-15.
