If you've got a tracked loader, you should check out those Bridgestone polartreads they came out with a couple of years ago. We use 'em and they let you stop sooner and dont spin in the snow and ice, something about the rubber edge being sharp and biting into the ice and snow.
Saw them on ebay pretty cheap, but we buy through an online dealer that we've been using for a couple of years out of Ohio, although I think they have warehouses in various states they ship from, names midwest equipment. Anyway, the tracks are awesome and we have already bought them for all of our CTL's (4) that we use for snow removal each year, they just let you get done about 40% faster b/c of the grip they have and that means less time in one parking lot and more time spent on the next, which means big $$ to me.
They cost about $600 more than a regular track, but once you work out the time savings of 40%, the return on investment is well worth it. If I can clear 40% more snow, faster and paying my crews by the hour and maintaining my CTL's by the hour, I make that extra $600 back pretty quick.
Check 'em out online at Bridgestone's site, or go to the dealer I buy from at http://www.tracksandtires.com They really do make work easier. We still use a couple of skid steers for snow removal as well, when we get really busy, but during the winter those two have great big tires on them that give more ground pressure then knobby work tires. The guys at midwest call 'em safteymasters, or lifemasters, or something that ends "master". Anyway, they look like a truck tire and they work great on snow and ice, maybe not as well as the polar treads, but still, its nice to have options if all you have is a skid steer.
I'll post some pics once the snow hits here, we're still mowing lawns though thank goodness, hopefully the snow wont hit us too soon! Anyone else have some recommendations on how to get more traction during the winter? I'm always looking for something to help me out.
