Any tire chain on the rear wheels would be my first choice , studded snow tires are available to. Plows or snowpushers are good for moderate and lighter snow for the 12 to 16" range. Your bucket will deal with heavy snows if the the blade can't at a slower pace of course.
Blowers have a relatively slow travel speed because all the snow must travel through the shute. But you handle it once and its gone 30 to 40 ft away and the volume is greatly reduced.
I disagree about needing a hi flow machine for blowing snow. If you are going to be doing alot yes it is a benifit, because you can put more of your engines hp to the blower and therfore travel faster. My 773 has 16.9 gpm at 3000 psi which = 27 hp to the blower. Your Cat is very near this (slightly higher I think) I would hazard a guess that a 40 hp tractor would have a hard time keeping up, because what the skid lacks in hp it will make up in agility. But if you want to blow snow like a 60 hp tractor you should be looking at a high flow unit.
I push a 10' blade with my 773 for our dry snowfalls, usually less then a foot and have never had to put the bucket on instead.
I had a blower last season but sold it again, I don't have a problem with drifting, we almost never get over 18" and I have lots of room to put the snow. That coupled with the fact my yard is largely pit run gravel with 4 to 10" stones that trip the edge on the plow and would force a blower or bucket equiped machine to travel vary slow, not to mention the projectile potential. The blower was a used Erskine 66" set up for a 12 gpm machine so I run my loader at a lower throttle. It would hurl snow 25 or so feet and in 6" dry snow I could travel 4 to 5 mph. But with a blade I coud run flat out.
If I can get you a figure on any snow equipment let me know.
