Abstract
A double latch system for maintaining an implement outrigger in a folded position, including a primary latch member which receives a locking pin to secure the outrigger in the raised position, and a pivoting secondary latch having a hooked end which automatically aligns with a latch pin when the locking pin is removed from a storage position for insertion into the primary latch. To lower the outrigger, the locking pin must first be removed from the primary latch, and the secondary latch hook must be pivoted and held away from the latch pin by lifting the secondary latch and inserting the locking pin in the storage position.
