A combination shovel and lawn rake and, includes a hollow rake handle with a rake head pivotally mounted on its lower end with a multi-point linkage for movement between a rake position and a raised position. A rake control knob near the handle is effective to move the rake head between a rake position and a raised position. A shovel is pivotally connected to the rake handle for movement between a shovel position and a storage position, where spring clips secure the shovel handle to the rake handle in both positions and a release mechanism aids in the release of the shovel from the clips so as to allow a change in its position.
