<strong>Defining</strong> <strong>Solution</strong>s – Part #1<br />
• Protect Grain Harvest:<br />
• Grain = High Value Commodity<br />
Farmer Participation<br />
• Protect the Value, Quality, and Marketability of Grain<br />
• Preserve Grain <strong>Harvesting</strong> Practices:<br />
• Harvest Efficiency (Harvest in Timely Manner to Avoid Loss & Degradation)<br />
• Minimize Impact to Machinery, Labor & Fuel Costs<br />
• Retain Versatility of <strong>Harvesting</strong> Equipment (Alternate <strong>Corn</strong> & Soy Harvest)
<strong>Defining</strong> <strong>Solution</strong>s – Part #1<br />
Farmer Participation<br />
• Provide Sustainable Ag Practices:<br />
• Considerations:<br />
• Nutrient Removal<br />
• Preserve Soil Conservation Practices<br />
• Customer Requirement:<br />
• Provide Machine <strong>Solution</strong>s That Allow Selective Harvest of <strong>Cob</strong>s Only<br />
• <strong>Cob</strong>s to be Gathered & Delivered in Form Acceptable for Storage,<br />
Transportation, & Processing
<strong>Defining</strong> <strong>Solution</strong>s – Part #1<br />
Farmer Participation<br />
• Define Practical Logistics <strong>Solution</strong>s:<br />

Full Definition Req’d To Develop Successful Machine <strong>Solution</strong>s
Developing Potential <strong>Solution</strong>s<br />
• Analytical Tools Utilized at Deere:<br />
• Combine Productivity Simulator:<br />
• Determines Combine Performance With Various Attachments<br />
• Logistics Simulator:<br />
• Estimates Field Logistics, Machinery & Manpower Needs, & Harvest Efficiency<br />
• Can Extend to Over – The – Road Logistics Study<br />

Combine Tools To Evaluate Potential <strong>Solution</strong>s
Combine Productivity<br />
Simulator:<br />
• Deere developed programs from Easy 5<br />
simulation software<br />
• Dynamic model has either equations or<br />
dynamic models of each portion of the<br />
combine system that interact (header,<br />
separator, cleaner, unloading system,<br />
propulsion system, engine package, etc.)<br />
• Can vary all field attributes that affect the<br />
combine productivity (yield, soil cone<br />
index, slope)<br />
• Provides Deere with a tool to measure the<br />
efficiency and productivity of the combine<br />
under various machine configuration<br />
changes<br />
• Program can simulate a second stream of<br />
material to handle and discharge (stover)
Logistics Simulator<br />
• Deere developed programs from Extend<br />
simulation software<br />
• Simulation includes combines, grain carts,<br />
trucks<br />
• Can vary all field attributes that affect<br />
logistics<br />
• Yield, field size, cart and bin size,<br />
ground speeds, truck location<br />
• Provides Deere with a tool to measure the<br />
efficiency and robustness of a customer’s<br />
equipment operation to a wide range of<br />
scenarios<br />
• Program can simulate a second stream of<br />
material to handle
Economic Model<br />
• Deere developed model for simulation of<br />
harvest cost per acre<br />
• Includes the costs associated with harvest<br />
• Capital equipment<br />
• Labor, fuel<br />
• Maintenance, crop changeover, downtime<br />
• In field operation, transport field to field<br />
• Trucking<br />
• Farm scenario (yield, field sizes, distances<br />
between fields)<br />
• Provides Deere with a tool to measure the<br />
cost per acre of a customer’s operation<br />
and what variables affect cost the most<br />
• Program can simulate a second stream of<br />
material to handle
