Brent what did you decide to do?
Like you I have a long driveway (1 mile gravel) to get to where the country maintains the road (they do a good job and are quick to start post snow storm).
I'm waiting on a Mule to arrive at the dealer (promised this month or next). First thing I will buy for the Mule since it is intended as a taxi from our house to the gate
are four of these:

We do get big snows (2 foot plus) but those are rare. What is common is ice, ice so bad, so thick, so long lasting (only 3 days in the last 3 weeks above freezing here) that
there have been two times in the last 3 weeks where I didn't even risk the 4Runner and it has studded snow tires.
So the dealer is pushing me towards a snow plow. He says the Mule SX is powerful enough but slow. He also said to start early in the snow storm, to knock off 2-4 inches at a time
and not wait until 12 inches have piled up.
From what I've read about those chains the Mule SX shouldn't have a problem at all on ice. I'm still mulling over the snow plowing with the Mule thinking like you've been mulling over
that the SX is a bit small, that the blade size needed to get both tire tracks when angled is too big for the SX.
I know with gravel we can't get the road perfectly clean, but when it does melt (and thank God that snow and ice can evaporate even from a solid form/sublimation point) it does slowly dissapear
even when we have (frequent) long periods below freezing.
Right now, having just taken the plunge into Mule SX world, I'm more worried about the plug fouling I've read about here in cold temps.
Can we not put an oil pan heater on the SX?
On my 4Runner I have heater in the block and an oil pan heater.....for when it doesn't get above 10F for days on end.
