I can't answer you specifically as my experience with tracks is from an MBT (Main Battle Tank- M1A1 Abrams) but I can tell you a lot depends on the surface under the ice as well as weight of the vehicle. Tracks can offer excellent traction on many surfaces but they are not "unstoppable". The one your looking at seems to have "smooth" track, as in not very aggressive to keep from tearing up the ground too much. On a very hard surface with a crust of ice on top it may be nearly useless. I've had tanks hit ice on pavement and it's not a fun experience. 68 tons of runaway tank that can't stop or steer is a butt clencher.
I'd see if there are any forums which have info directly related to that type/model dozer and see what those folks say. If there are "bolt on" traction adders then it may be great. But only if they work.
I can also say that tracked vehicles are maintenance intensive. Keeping track tension is viral. Inspecting the track for missing or loose nuts/bolts is a constant effort not to be ignored. And any bolt on traction adders will be susceptible to coming off. They aren't free so you have to pay attention to making sure they stay tight.
That doesn't look to be a big dozer so if you have any plans to do any excavation you'll want to do it while the ground isn't frozen. It also appears to have a finish bucket on it. Those are ok for soft and shallow digging but you'll want a toothed blade for real holes or frozen ground.
Just for fun:
