A pulling tool is provided with a rotatable drum having a cable wound thereon. A motor is drivingly connected to the rotatable drum and the rotatable drum and motor are disposed within a unique housing structure. The rotatable drum is driven by a planetary gear system that is disposed within the rotatable drum to provide a compact assembly. A belt and pulley system is provided for delivering torque from the motor to the planetary gear system. The rotatable drum is provided with a two-piece stepped construction that allows the planetary gear system to be assembled within the drum and allows for the initial wraps of a cable around the smaller diameter portion of the stepped drum.
