CHARLIE - I know PLENTY about moving snow. I just don't have to move the stuff six months out of every year like you do!
I used to clean the whole barnyard with the M & loader when I was about ten yrs old, and our barnyard was as big as a baseball field, including the outfield. Dad was running two pair of IH weights on the M back then (600#), and chains. I'd make piles the size of my shop, 24 ft X 36 ft X 8-10 ft tall. The loader on the M can pile snow a LOT higher than the loader on the Super H.
When you have lots of snow to move, use something BIG. My concrete drive sloping up to the road complicates things for me. Tough to get decent footing even with weight & chains, plus I don't want to bust anything, expecially not my loader & tractor, or the concrete drive, so I go slow.
I will say the 70 & new to me this year 42" frt blade did pretty good on the little snows, 1"-3". But the "Storm of the Century" took about an hour to move, had to air up a flat tire on the SH, back out of the shop thru a 3+ ft deep drift, and all the snow was drifted from a foot to 2+ ft deep in front of the attached garage, and I had to drag it back from the garage and push it across the drive past the shop. When I was dragging the snow it would come away from the drifts in chunks eight-nine feet wide from my 6-2/3rds ft wide blade.
I didn't have any problems a couple years ago when we had over 100 inches of snow. About early Febuary SON & I had a snow moving party, pushed all the snow away from in front of the house so when it melted it didn't over-load the drainage tile around the house and seep into the basement. We were pushing 2-3 foot deep snow plus taller piles 100-150 feet. We had piles 3-4 ft tall in front of the 80 inch blade & 80 inch wide bucket on the M, both tractors with weights & chains.
Yes, turf tires with chains may be better than chains on lugged tires, but is it worth the hassle of swapping different wheels/tires to mount chains on turfs or smooth tread tires? Maybe if you already have them, but the 2, maybe 3-4 times a year they'd do me any better than what I already have I'm not spending the money or time to swap tires. Takes me about an hour to chain up each big tractor, and I can move more snow in 15 minutes after putting the chains on that I could in two hours without chains.
