A telescoping mast assembly having a ball drive actuator drive system. A telescoping mast section is housed within a base mast section mounted to a base plate. The base mast section pivots about a pivot axis between a lowered, horizontal position and an upright, vertical position and includes an upper elongate body disposed an upper side of the pivot axis and a bottom end disposed on an opposite side of the pivot axis. A ball actuator drive includes an electrically powered motor that drives a ball screw reciprocally inward and outward along a linear stroke path. A remote end of the ball screw is attached to the bottom end of the base mast section and, by pushing and pulling the bottom end of the base mast section, pivots and maintains the base mast section to alternative positions between the fully raised and the fully lowered positions. A telescoping mast section is housed within the base mast section and telescopes between an extended position and a retracted position. A secondary ball screw actuator is housed within the base mast section and is coupled to drive the telescoping mast section between its extended and retracted positions.
