  1. Disc Mower Optimization Team Number: 98.09 Members: Michelle Mattera Joseph Salvia Tiffany Stith Bob Ward Customer: Rich Adams, New Holland Advisor: Dr. Valery Roy Mission: To design, assemble, and test a system which will reduce streaking by optimizing blade angle, lifter angle and shroud shape through testing and analysis. Approach: Using TQD, evaluate and modify existing design based on prioritized wants and constraints.

  2. Customers: • New Holland • Rich Adams : Project Engineer • Ken McLean : Design Engineer • Joe Griffiths : Marketing • Chris Peters : Brim Tractor Co. • Ray Coates : Farmer • OSHA

  3. Benefits of Solution • More even cutting of crops • Cost savings to the end user • Competitive advantage • Increased versatility of the mower • More aesthetically pleasing cut

  4. Mission Statement: • To design, assemble and test a system which will reduce the amount of streaking of the New Holland disc mower by optimizing one of the following: • Blade Angle • Lifter Angle / Lifter Shape • Shroud Shape

  5. Maintain drive train Retrofit capability Minimize cost increase Minimize noise User comfort Dimensions Dimensions, Power Percent of cost dB dB, Vibration Wants: Metrics:

  6. Increase durability No clogging Easy to maintain Resistant to corrosion SAE standard hardware Lifetime of part (hrs) Crop flow rate Down time (hrs) Operation hours Fits standard tools Wants: Metrics:

  7. Customer Constraints • Unchanged power requirement • Must fit within the existing equipment • Tractor cutting speed unchanged. • Adjustable cutting height • Must cut wet or dry crops

  8. Benchmarking / Competitors • Sickle Cutters • Kuhn Farm Machinery, Inc.

  9. Concept Generation • Major Factors • Blade Angle • Lifter Angle • Shroud shape • Method • Velocity profiling with hot wire anemometer
