H.F. Hauff Pruner Housing & Ergonomics, Erich E. Heilman Jan 2016

H.F. Hauff Pruner Housing & Ergonomics, Erich E. Heilman

All Undergraduate Projects

The technology of electric tree pruners in the current agricultural market has many engineering problems, including; a deficit in power output, excessive overheating, and ergonomics. The 3-man pruner team has coordinated with H.F. Hauff Co. Inc., an agricultural equipment company owned by Neil Hauff, to produce an electric pruner prototype which addresses these problems. The methods used to design the optimal pruner prototype includes traditional engineering stress analysis, force flow analysis, finite element software, and Solidworks modeling software. The construction of the pruner involved manual machining methods and C.N.C. (Computerized Numerical Control) mill technology. During the design process, the team …


Everyday Farm Life In The Moxee Valley 1915-1950: Historical Ethnography, Terri Towner Jan 2016

Everyday Farm Life In The Moxee Valley 1915-1950: Historical Ethnography, Terri Towner

All Master's Theses

This study collected oral histories of those who lived or worked in the Moxee Valley, within the greater Yakima Valley of Washington State from 1915-1950. It documents and records the historical and cultural processes of farm life and its evolution for people living in this foremost hop-growing region of the United States. The larger goal is to characterize the community and social processes for use as primary source documentation to create historically accurate programs at the Gendron Hop Ranch-Living History Farm near Moxee. Nineteen participants were interviewed. Topics addressed in the study include farming in the Valley, the household, roles …
