Abstract. A John Deere 4400 elevator system was donated to the Clemson University Agricultural Mechanization and Business (AGM) program for educational purposes for capstone students to design and construct a room scale precision agriculture yield monitor demonstration unit. A design limitation required that the unit must be capable of fitting through a standard classroom door. The unit measures 203 centimeters by 71 centimeters (80 inches by 28 inches) and contains all the systematic sensors required to produce a yield map housed within a functioning field combine. The yield monitor is mobile and capable of producing a variable yield map within a classroom or laboratory. Such a platform allows students to focus on the precision agriculture technologies and not on operating the combine in a field. With the incorporation of a geographic information system (GIS), students have the opportunity to experience precision agriculture technologies, zone and data management principles in a laboratory setting. The use of a grain yield demonstration unit can greatly increase the learning opportunities within a laboratory setting, without the barriers associated with demonstrations in the field. The yield monitor demonstration unit will primarily be used in the AGM program laboratories and cooperative extension field day demonstrations by Clemson AGM instructors and extension associates to help educate students and growers about data management and sensor troubleshooting.
