Abstract: A storage lock assembly for a lawn mower can include a primary pedal, a lock striker, a secondary pedal, and a deck lock that can be manipulated to selectively lock a mower deck into a stowed position and unlock the deck from the stowed position. The primary pedal can move the deck between a plurality of operating positions and the stowed position. The secondary pedal can include an engagement member and be pivotably attached to the primary pedal. The deck lock can be movable between a locked position where the deck lock is engaged with the lock striker, and an unlocked position where the deck lock is disengaged from the lock striker. When the deck lock is in the locked position and the secondary pedal pivots relative to the primary pedal, the engagement member can move the deck lock away from the lock striker and to the unlocked position.
