I've got the Woods 1012 loader w/66" HD bucket on my TC33D. I've picked up a bucket full of sand with only my loaded rear tires (CaCl filled) for ballast and it worked OK. (I would not have wanted to drive on much of a slope, or on rough ground). It's a lot more comfortable to do this heavy stuff with an implement on the back, as well as the loaded tires. With a 7308 loader, I'd bet you'd be fine with either an implement or the tires. You probably wouldn't need both, since the 7308 will not pick up as much as the Woods 1012. Also, a lot of the stuff I pick up is lighter than the sand (rocks, dirt if fairly dry, etc) so I have no problem with just the loaded tires.
