Hi all,
New to the forum here, and a great site.
My opinion on building a road with tons of boulders. I would have to say an 8 with a semi U. Been on a 6R for a year now and LOTS of BIG stuff coming in. A 3' lifts,but a 26' fill, however I seem to see ALOT of 4' rocks. The dozer keeps up fine so long as the drivers dump where they should. All trail dumps hauling in and between 4000-5500 ton a day. So long and its just short of the edge and I can bury the bones and spread the fines over the top it comes out nice.
We have an elliot attachment on the roller to break up the top surface and it works nicely, with just the 6 by itself, it is too light to crush the top surface. And when red topping if it get's 5 or 6 tenths too high, it can be a real SOB to cut. Thats when the 8 would come in handy. Otherwise the 6 is a great machine.
