I wasn't staying up to plow every 6 inches or so, I just went to bed. I didn't expect all that snow anyway, it is unusual here to get that much. In another week or two, you will never guess we had snow here. It goes fast.
For that reason i have a plow, great in summer for dirt work. Blower is heavy lot of moving parts, for my 68 more of a headache than i want to deal with
6" is worst case without traction, we got 10" overnight bunch of rain on top, old ice underneath, get stuck just stand on the back hitch rock it in gear, pulls itself out, only have 50 lbs on back no wheel weights, have ice chains. Mine is 12 horse same as yours, plenty of power
Experiment, you'll figure out what you need. Here's a pic, what i meant earlier about building ramps then just push it over the top so you don't run out of room
