The manually powered wheeled-levered shovel/launcher device for the purpose of snow removal, which has a handle, and shovel shaft pivoted to the handle at one end and a snow shovel head at the other end of the shovel shaft. A collapsible foldable wheel assembly acts as a fulcrum is attached to the device for easy handling a snow load. The shovel head is able to tilt downward against a spring-loaded mechanism for the purpose of altering the launch direction from upward direction due to centrifugal force around the wheel resting on the ground to forward direction when a sudden force downward is applied on the handle.
