Note:
If the blade stays in a horizontal position, the
blade is balanced and can be used.

3. If the blade is not balanced, file some metal off the end
of the sail area only (
Figure 96 ).
4. Repeat this procedure until the blade is balanced.
Installing the Blades
1. Install the blade onto the spindle shaft ( Figure 99 ).
Important:
The curved part of the blade must be
pointing upward toward the inside of the mower to
ensure proper cutting.
2. Install the spring disk and blade bolt ( Figure 99 ).
Note:
The spring-disk cone must be installed toward
the bolt head ( Figure 99 ).
3. Torque the blade bolt to 115 to 150 N∙m (85 to 110
ft-lb).

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 100 ).
6. Rotate the deck idler clockwise and remove the mower
belt (
Figure 100 ).
