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 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.
