I just checked out the new site. NICE. My bobcat plow is a Meyer 7.5 off a truck that has been modified slightly. I cutom built a mounting bracket that ocilates about 15 degrees to allow the plow to follow contours. It works great! I'll be ordering soon.
The wings attach on a rotating keyway. As the moldboard fold forward, the wings stay in the same postion, and the moldboard rotates in the keyway. Not a very difficult concept, but I can see where it would confuse a ford owner. LOL
It is probably the most asked question, I hope this will help.
There is a channel that is bolted to the back of the plow using 6-7/16" bolts(this bracket may also be welded if you prefer), the wing itself has a heavy duty piece of flat stock which we call the "key". The key slides down from the top into the channel that is mounted to the plow, allowing the wing to move free up and down, as the plow tips forward the key slides up in the wing keeping the wing level and allowing the plow to tip forward without interfering with it's normal function. The wings will work on the other brands most with out any modifications. The plows we have listed on our web site are the ones with the most differences between them so we made wings for each brand, the differences are very little as they all use the same brackett with only slight changes to the key location. I hope this has answered your question, the concept is very simple and the product is very user friendly.
The key does not rotate, it only moves up and down in the channel, the curve of the blade and the design of the bracket allow the key to move up while the blade tips forward. The wings with rotating keys seem to after time require the use of a 8 lb mall to remove, with our concept only a pair of hands is ever needed to lift them out.
U caught me BRL. Actually though I have run pro-wings and loved them. Always thought it would be nice to have them perpindicular to the blade. I may actually give this one a chance.
Sorry for being stubborn, guess it is the New England Yankee in me.
