I was out in chest deep snow last year with my Max IV on rubber tracks, no issues at all, just take it slow and no sharp turns. If it does start digging a hole, just roll backwards and forwards a few times to pack down the snow so you can take another run. During one ride on a frozen lake my buddy in a 1000CC Canam took off down a frozen creek, this creek is spring fed and ends in a spruce bog with no exit. My friend did well driving the length of the creek at 50-60km/h, when he reached the end with no exit he let off the gas and the quad fell into the swamp. I rode up beside him in the Max and as soon as I stepped out it was like msafi65 described, I sunk right down to the bottom looking at the top of my track. Without the Max that Canam would still be there lol.
