University of Iowa Farm Machine Music This incredible machine was built as a collaborative effort between the Robert M. Trammell Music Conservatory and the Sharon Wick School of Engineering at the University of Iowa. Amazingly, 97% of the machines components came from John Deere Industries and Irrigation Equipment of Bancroft Iowa. It took the team a combined 13,029 hours of set-up, alignment, calibration, and tuning before filming this video. It is now on display in the Matthew Gerhard Alumni Hall at the University and is already slated to be donated to the Smithsonian.
