Do you have anymore pictures of this wing? Never quite seen a set-up like that!
Our wing was originally designed to be used on an older, rigid framed machine. The brace bolted to a bracket on the tandem drive between the tires. Intended use was the moldboard and the wing parallel. I built a bracket the bolts to the moldboard using two cutter edge bolts. The brace telescopes but once I got it figured out I never change it. You can also move the bracket on the moldboard to change the angle of the wing. It's not designed to do extreme winging. Use it with common sense and it works fine. I've never had any problems with it and have never done any damage to the moldboard. But I think that is possible if improperly used. I hate to get weather that requires me to use it. But when that weather comes, I'm glad we have it. Been using it since 1990. My roads are always wide enough for two lane traffic. Other townships in my area will be down to one lane paths thru the bad areas by the end of a hard Winter.
