A sucker rod tong assembly for fastening together sucker rods to a rod coupling, where the assembly can include a two-stage mechanical drive mechanism. The first stage can connect an upper sucker rod to a lower sucker rod via a rod coupling. The first stage can be limited in mechanical ability to tighten the connection to a pre-set shoulder torque value. The second stage can then be hydraulically and mechanically sequenced, using a linear gear drive mechanism, to rotate a main tong pinion gear that can further rotate the sucker rod connection through a fixed circumferential displacement to a mechanical stop.
