I've just installed Turkey wings on a 9 footer. Waiting for it snow now. They are supposed to be more efficient than a V plow because you are able to use your total blade width. The snow will continue to roll with the blade as well. With pro wings the snow really doesn't roll that great.
Seem's we have a problem. What position do most people use the V plow in for clearing snow? Straight blade. V is used to bust it open, Scoop for cleaning up all those nasty trails left by the straight blade.
Have put several sets of bolt on wings on V plows. West, Boss and Fisher. In the V- position you get alittle extra off the ends and a little more wheel clearance when punching throught the drifts. In the straight blade you have nearly the same effect as a bucket blade.
When you go to the scoop position you have a deeper scoop to carry more snow. However the wings in the straight blade or moved just to the beginning of the scoop position with bolt on wings will hold more snow thatn the blade in the full scoop position.
Down side to install. You have to weld the pin to the face of the blade or cut a hole through the back of most Boss plows to do the wing install.
Upside. easy to remove when you need a smaller blade or for transport.
I went the hard way .. 810 power plow... Touch the button and the wings move in and out and also pivot forward. No need to get out in the cold and less spilt coffee>
