A return rack can be fixedly coupled to and positioned along a longitudinal length of the concrete nail driver The driver return assembly can include a solenoid driving a plunger in a reciprocating motion in a homeward direction and a driven direction. A return pawl can be coupled to the plunger and pivotable into a pawl raised position relative to the plunger in which the pawl is engageable with the return rack during movement of the plunger in the homeward direction, and pivotable into a pawl lowered position relative to the plunger in which the pawl is not engageable with the return rack during movement of the plunger in the driven direction.
