Installing the Blades
1. Install the blade onto the spindle shaft (Figure 101).
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. The spring
disk cone must be installed toward the bolt head
(Figure 101). Torque the blade bolt to 85-110 ft-lb
(115-150 N-m).

Removing the Mower Deck
Before servicing or removing the mower deck, the spring
loaded deck arms must be locked out.
WARNING
Deck lift arm assemblies have stored energy.
Removing the deck with out 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. Stop engine, wait for all moving parts to stop, and
remove key. Engage parking brake.
2. Remove the height adjustment pin and lower the
deck to the ground.
3. Place the height adjustment pin in the 3 inch (7.6 cm)
cutting height location. 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 102).
6. Rotate the deck idler clockwise and remove the
mower belt (Figure 102).
