A towing dolly is provided for relocating wheeled loads such as boat trailers, camping trailers and airplanes where towing forces required may be substantial. The towing dolly may have a wheel assembly with a drive gear disposed between proximate treads. The towing dolly may have a narrow wheel width providing easy steering and compact size for storage. The towing dolly may have a motor with a gear sprocket. A linked chain may transfer power from the motor to the drive gear located between the double treads. The dolly may have a steering arm extending perpendicular to drive direction allowing the operator to stand away from path of movement of the load while providing adequate leverage to steer the dolly. The dolly may have an alternate configuration with a power source located on the dolly providing operation independent of plugins or extension cords.
