No kidding, rubber tracks and spinning in rock, ud have to be brain dead if you put this machine in rock. As for seat time no, put will get the chance to run one this spring, we already hve one sitting on are job, i think it would come in handy working with 10-15 9630's with pans, it can go run the slope in the cut then, put it in high gear and run to the fill knock the fill down and straighten the slopes up in the fill, instead of having a 6 spend 30 mins to track from the fill to the cut, this thing can do it in 2. So say you have to go back and fourth from the fill to the cut 4 times a day, you lost 2 hrs of run time with the 6.
And have you ever worked around the steiger quadtraxs??? If so then you know what them things can go threw, i assume this thing is just as good in the mudd as the quads. But will know more this spring.
