Re: pullthis with your tundra!
the opperation of the drag we use is very well thought out.
there is different gears to control the speed the box travels
but also a micro switch is tripped that drops the pan flat on the track which has bars so it acts like a grader.
when the pan is flat and box to the front the drag actually picks the rear off the ground so that all the weight 40,000 is being draged. nearly imposible to drag ever for a 20,000 semi.
