Extreme Bulldozers and Agriculture BUlldozers Machines
hilarious how he puts down the blade to add more resistance and the dozer still pushes through!
Dozers can pull incredibly hard plus, that one had the right grousers (tracks) for that type of soil.
That thing is not even rolling coal, all go no show. I'd rather watch a 100+ year old CASE steam traction machine blasting embers out of her stack, hauling the sled down the line like it's nothing.
Pay attention 3:17 on, reason he has no trouble and probably why he dropped his blade is the pan (the part on the sled that digs in to slow you down) Isn't even touching the ground, he can't get his rippers low enough. So he probably dropped his blade to try and get that to make it "harder"
