A shovel assembly having a shovel head and a handle shaft. The handle shaft has a first end and a second end, wherein the first end of the handle shaft propagates along a longitudinal axis. A pivot joint is interposed between the shovel head and the handle shaft. The pivot joint selectively enables the shovel head to rotate about the longitudinal axis. The pivot joint is configurable into three distinct conditions. In a first condition, the pivot joint rigidly couples the shovel head to the handle shaft. In a second condition, the pivot joint enables the shovel head to rotate around the longitudinal axis of the handle shaft in a first direction. Lastly, in a third condition, the pivot joint enables the shovel head to rotate around the longitudinal axis of the handel shaft in a second direction. A manual control is provided on the shovel for selectively configuring the pivot joint between the first condition, the second condition and the third condition.
