once the snow is packed as a result of driving over it, it turns to ice and the tracks don't grab. Driving your track lift in the snow would be similar to walking in it the first time, pretty good traction until you walk many times on the same path and then it gets slippery. Tires with chains or studs is the way to go if plowing with a skidsteer.The tracks on my lift actually surprisingly awesome in the snow. I think it’s because there’s so much weight on relatively concentrated (normally turf destroying) tracks. Of course it all depends on what kind of snow/ice etc. I never ran a track machine, but have heard the tracks are like skis in the snow. I can see how they would be.
