Matt, As far as the strength of the support linkage etc, let me just say that I don't think you have anything to worry about.

Here is a video of the same linkage used as a liquid side dress coulter and all part of the same Free Farm system as Joe mentions in the video. Apologies for the hokey graphics in the beginning but its only a 2 minute video.

This system is obviously not for everyone nor every operation. But there is likely a very signifant ROI for some operators in some locations and conditions. 

I don't want to get into specifics of the mountings right now. There will be a lot more information coming out in the future.
