Removing the Mower Deck
Lock out the spring-loaded deck arms before servicing
or removing the mower deck.
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. Shut off the engine, wait for all of the 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 99 ).
6. Rotate the deck idler clockwise and remove the
mower belt (
Figure 99 ).
