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 of the moving parts to
stop, remove the key, and engage 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)
height-of-cut location.
Note: This locks the deck-lift arms in the lowest
position so that when you remove the deck, the stored
energy in the deck spring is released.
4. Remove the belt covers.
5. Lift 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 102).
