The invention involves a hand held, power-assisted cable-pulling apparatus. The hand held, power-assisted cable-pulling apparatus has a housing, a take-up wheel, a drive transfer coupling, at least one dog pawl, a line, and a ground fixation mechanism. The housing has a hollow handle body within which is a fluid-powered actuator, a fluid control valve, for controlling fluid pressure supply to the actuator, and an operating trigger for the control valve. The wheel has a circumferential line-engaging portion and a concentric ratchet portion. The take-up wheel rotates about a take-up wheel shaft, which extends through the center of the take-up wheel. The take-up wheel shaft is attached with respect to the housing. Further, there is at least one dog pawl pivotally attached with respect to the housing. There is also a line having a cable attachment mechanism. The take-up wheel may be selectively rotated in a clockwise take-up direction.
