In May (2015), U.S. patent #9,032,701 was granted to Dean Walker and Walker Manufacturing, covering the design of the GHS blower system developed for the Model MS14.
This unique design simplifies and compacts the drive train by powering the blower and the mower deck with a common drive shaft. The resulting benefits to the MS14 are reduced cost while maintaining strong performance of the GHS blower and compact size of the tractor.
