2006 snow bear plow, winch will not lift plow, sounds like its turning but is not lifting plow consistantly, Is something loose?

Yes, Check where strap or chain is mounted to winch. It could be loose or have dirt or oil on it something to make it slip.On mine there's a brass piece that raps around the shaft, It got lose and dirty so I cleaned and tightened it. If you pull motor off winch to check gears [don't use gear] when reassembling it's too thick when it's cold. I used white spray lube. Hope it helps!

I have had the same problem more than once, and have had to replace the drum assembly, which is the part that holds your strap or chain and is attached to the winch. The teeth on it tend to wear down because it is a soft metal.
