The rule is to always be driving on cleared ground.
Snowblowing storm multiple times, in shallower snow, is a lot more “forgiving”, especially if you’re learning, when you break this rule.
This usually happens when:
Blowing deep snow too fast and snow comes over top of blower into wheel path.
Taking “first pass” and then having to back up (or turn around). Rarely can you back up perfectly in the cleared path that is exact width of blower, then you start knocking snow into cleared path with either rear tire or side of blower....then your scr*wed.
One solution on big storms is to only take first pass into snow 1-2-3-4 lengths of snowblower (depending on likelihood of getting stuck), then back up and widen the short path you just made, then repeat, never “boxing” yourself in a narrow snow alley.
Another solution is instead of backing up a long path, back up one length, go forward “fanning” left and right until you’ve cleared a spot to turn around.
Do you have chains? Ballast weight?
