A control lever assembly with handle lockout capability including a lever element selectively positionable in a locking position and lockable therein by movement of a handle thereof to a lock position. A first biasing member is disposed on the lever element in an operative position to exert a first biasing force against a detent element, and a second biasing member is disposed in opposition to the first biasing member and is operable to hold the detent element to allow free pivotal movement of the lever element relative to a base.
