DONALD - It's Art that has that byline.
SON tried to clean the driveway once with the Super H & loader without chains and just the 40" wide bucket. There was 4-5 inches of snow with a sheet of ice under it, it rained, then cooled off and changed to snow.
Without chains the Super H would not even attempt to climb the slope in our concrete drive. And the Super H has about 500# of calcium chloride solution per rear tire PLUS about 300# of cast iron weights per tire, something around 1600 pounds of added weight. The tires have good tread, similar to a Firestone 23 degree, but are DAYTON brand, made by Firestone in a size 12.4" x 38" 4-ply. I've never weighed the chains I have for this tractor but they must weigh at least 200# per chain, so add another 400#, so 2000# added weight just to push snow around. And I still slip & spin!
The Farmall M doesn't have fluid, never did, and used to have two pair of weights per rear wheel, about 300#/wheel with hardware. We have chains for it too, but we added THREE 150# weights per rear wheel, 900# total, and without the chains it's pretty helpless. And compared to CC weights, these weights were cheap, about $200 total including hardware! At today's prices that two pair, about 104# of CC weights.
I've never had both FARMALL's across a scale in their current configuration but I'd guess they both weigh within 500# of the same weight, between 7000 and 7500# each. I know the Super H used to weigh 5250# without the loader & chains and only one pair of weights. The M was on a trailer the last time I weighted it, minus the 900# of weights, and I have no idea what the trailer weight was.
It's funny, I add 1000# to 2000# to my snow moving tractors. That's like bolting one or TWO Cub Cadets to them! But My Buddy's ATV will still move more snow that either one of them, or even BOTH of them combines.
