H.F. Hauff Pruner Cutting Blades, Wyley Stewart

Engineering Technology, Safety and Construction Senior Projects

Apple orchards are a critical component of agriculture in the United States, and keeping the apple trees in the best shape for optimum growth and production is hard work. Neil Hauff, an agriculture industry expert, challenged students at CWU to engineer a power assisted tree pruner. Across the country, apple orchards need pruned every season. The pruning of the trees is strenuous manual labor that requires many man hours. The proposed solution is to create a power assisted tree pruner that would minimize the amount of work needed to trim each tree branch. This project has been separated into three ...

Senior Project Hauff Tree Pruner, Brian Woolery

Engineering Technology, Safety and Construction Senior Projects

Neil Hauff, a business owner and entrepreneur from the Yakima valley challenged a team of engineering students from Central Washington University to design a motorized apple tree pruner. This report will discuss the engineering and construction that went into creating the housing of the tree pruner. The housing component needed to be able to protect the moving parts of the pruner, while withstanding the rotational torque produced by the Makita power drill used to drive the pruner. The biggest constraint in designing the housing was to keep the weight of the housing component under 1.5 lbs, while still keeping ...
