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 the engine, wait for all moving parts to stop, and
remove the key. 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
6. Rotate the deck idler clockwise and remove the mower
belt (Figure 103).
