I am wondering why you think the 47 blower doesn't handle the heavy
wet snow well. I have the same blower on my 2wd 445 and I also own
the blade, yet the blower wins hands down for me. Yes, the blade does
well, I use it mostly for dirt, but that blower has moved tons and tons
of snow very effectively.
Weights, and chains may definately be required, especially in that
wet slushy snow that has fallen this year. The very heavy snow
we had in Ocotber was the worst for anything to move,
and I bet as the weather gets colder, and we get more normal snow,
you will like that blower very much.
You would need more weight and chains for the blade than
the blower. You might want to have them for use with both.
