I have a PC-50 (11,700 lb) with 2' bucket,rubber tracks and a 6'-ish blade. I use it to push banks (4 to 5' high) back on the 750 foot flat section of the drive by driving along the highest / deepest part of the bank using the blade to roll up the snow. I use the swing to clear out from in front of the blade and then push the bank off to the side with the bucket as I pass. It works pretty well and getting stuck is pretty much a non-concern but there are a couple of important points. One is my tracks are on un-frozen or just frozen leaf litter and not ice, I get very good traction allowing me to use all 10,000 lbs of tractive force on the blade - this thing will easily move a snowbank that stops a tractor dead. Two is I don't have a ditch on the side of the drive that I stack snow on. rubber tracks beat steel on on this surface. On hard ice, anything beyond 3 degrees of slope and the machine is a hazard, and you get zero traction - the bucket just pushes the machine around, and it's pointless to try and do anything. on snow it's pretty good. Ice is hard on these things as it will melt and freeze in and around the tracks and track motors when things cool off - I pretty much use it and then it sits until after the next thaw (but I do baby my machines a bit...) For just plowing it's extremely slow and quite messy - I used the rear blade of the tractor to clean up after bank pushback. I now use a rear mount blower and the mini-ex sits all winter.
