This Panama, OK, animal-powered stationary hay press, built in 1905, may be the only one of its kind in the U.S.
The antique press, housed at the Pasto Agricultural Museum at Rock Springs, PA, still runs. It will be on display at Penn State University's 2013 Ag Progress Days, set for Aug. 13-15.
Manufactured in Kansas City, the press was an early success in compressing hay into dense bales that could be moved by rail.
This press was originally owned by the W. Herb Cowen family and brought to central Pennsylvania, where it was donated to the museum by the family in 1998. Members of the Cowen family still help operate it during demonstrations.
Many thanks to John Baylor, emeritus Penn State University Extension forage specialist, for providing the photos and information for this photo gallery.
