I don't understand why you guys think that switching the adjustable link to the left side changes anything.
You're angling the whole implement, not just one side. The adjustable unit on the b series should be centered to have the implement level, so there should be an equal amount of tilt to either side, or at least very close.
The implements angle will be the same no matter which side the adjustable rod is on.
Example, from level you adjust up 2" or down 2", lets say that you get a 10 degree angle. Move the adjustable rod to the left side and do the same thing, you get the same exact results. Other than maybe a 1 degree difference when adjusting left and right, there is no good reason to be changing the adjusting rod from side-side.
