Many of the underground cable pullers of today feature a digital readout that gives the operator far more insight and control over what is happening underground. They are able to see and view the pulling forces, as well as the distance the cable has been pulled. They are also able to see and use the tension limiter, and take note of the pressure readings. In addition, the underground cable pullers are typically on wheels, and they have a stand so they do not need to be hooked up to a vehicle to be effective. They also have trailer hitches so you can connect them to a vehicle and move them to where you need them.
