Installing the Blades

The curved part of the blade
must be pointing upward toward the inside
of the mower to ensure proper cutting.

106 ).
Note:
The spring-disk cone must be installed
toward the bolt head ( Figure 106 ).
3. Torque the blade bolt to 115 to 150 N∙m (85 to

Removing the Mower Deck
Before servicing or removing the mower deck, lock
out the spring-loaded deck arms.
WARNING
Deck-lift-arm assemblies have stored energy.
Removing the deck without releasing the
stored energy can cause serious injury or
death.
Do not attempt to disassemble the deck from
the front frame without locking out the stored
energy.
1. Shut off the engine, wait for all moving parts to
stop, remove the key, and engage the parking
brake.
2. Remove the height-adjustment pin and lower
the deck to the ground.
3. Place the height-adjustment pin in the 7.6 cm (3
inch) cutting-height location.
Note:
This locks the deck-lift arms in the lowest
position when the deck is removed and the
stored energy in the deck spring is released.
4. Remove the belt covers.
5. Lift up the floor pan and insert a ratchet into the
square hole in the deck idler (
Figure 107 ).
6. Rotate the deck idler clockwise and remove the
mower belt (
Figure 107 ).
