X3 on the digger anchor auger carrier. I have used the mad dog one from Cabela’s too, and I can not recommend it. The velcro straps that they use to hold the auger in place are a major hassle.
You do get some slippage on glare ice, but it’s not near as bad as you do with tires. The only time that I had much of a problem with it is when try to pull two heavy gear sleds behind it. I did figure out that pulling a trailer on glare ice does work quite a bit better. Getting going took a little bit, but once moving it wasn’t much of a problem.
