Do a search,under sidewing plow, and in the Post pictures of my rig post page 3, there is a good description and pics of the plow in action. Look up the profile of the member named sidewing, I think he's the guy from Ontario, who purchased the North American rights to the design, and is/will be manufacturing them in Ontario, he should be able to provide any information you need.
Just ordered a new sidewing plow for my Dodge 2500. One of the contracts I have this winter requires I keep some park roads open, I'll let you know how it works. I'm hoping it will speed up some of my commercial accounts to.
