Iowa State professor did it actually lost YIELD on hydraulic verse airbags. I’m sure he’s 6 feet under somewhere.
That is part of the trial I was referencing. I guess I did not realize some of the data got published. I see it was one year of the trial and dryer year so Darr thought it didn’t matter as much when dry. It was continued for a couple more years I believe and results never changed. Here is a link to the article you have a picture of. Professor Darr is far from 6ft under. The stuff he is doing in the agricultural engineering department at Iowa State is pretty impressive. He was originally from Ohio and taught at Ohio State.
