I just installed a Black Boar last night in preparation for the coming storm here.

Regardless of which direction you go, be prepared to remove both the front and the rear skid plates on your CF600. Also, you might want to purchase a few nylon retainers (if you choose to put your skid plates back on in the spring) because you're gonna ruin a couple/three trying to get them out - even with an extractor. Why CFMoto uses these crappy nylon retainers is beyond me... seems like a more simple solution would have been to just use nylon threaded screws and to mold the 2 separate pieces that go up into the wheel well into one single part that attaches to a different spot, but hey, I'm not an engineer.
Because there's a crossmember right where the U-bolts would be best placed for my unit, it had to be moved either forward a few inches or backward a few inches and I had to go to Ace and buy 2 extra U-bolts and nuts to secure the mount to the frame sturdy enough. (I mounted it back a few inches to give a bit more sturdiness to the plow bars, plus it's a little more balanced being further back by a few inches.
The whole job took me about 3 hours completely by myself, but I suspect that with 2 people it could probably only take an hour... I had to keep going inside to thaw out my hands. Best part is now that it's done, detaching literally means pulling 2 pins and storing it away which would mean a total of about 2 minutes.
