  1. Energy Efficiency:Field Machinery Operation John Nowatzki Ag Machine Systems Specialist NDSU Extension Service Vern Hofman Professor Emeritus Agricultural & Biosystems Engineering Department

  2. Introduction • Fuel Use by Field Operation • Tractor Traction Technology • Regular Maintenance Schedule • Conservation Tillage • Energy Saving Practices

  3. Fuel Use by Field Operation Gallons/Acre • Grain Drill .6 • Row Crop Planter .3 • Combine 1.3 – 1.9 • Round Baler .7 • Corn Chopper (pt) 3.3 • Mower/Conditioner .4 Farm Machinery Economic Cost Estimates For 2005 University of Minnesota

  4. Fuel Use by Field Operation • Chisel Plow .6 • Moldboard Plow 1.3 • Field Cultivator .5 • Tandem Disc .4 • Stalk Shredder .7 Farm Machinery Economic Cost Estimates For 2005 University of Minnesota

  5. Tractor Traction Technology • Bias or Radial Tires? Radials 5–7% Advantage Michelin Agricultural Tires

  6. Tractor Traction Technology • Bias or Radial Tires? • Operate Radial Tire Pressures at 6 psi. • Operate Bias Tires at or above 14 psi. • Limit Tire Load to Manufacturer’s Recommendations

  7. Tractor Traction Technology • Bias or Radial Tires? • Increase Tire Pressure when using Mounted Equipment • Tire Slippage: 8-15% • Higher range for 4WD Tractors • Check Tire Pressure Regularly • Note: Less Soil Compaction with Lower Tire Pressure

  8. Tractor Traction Technology • Singles, Duals, Triples or Tracks? Duals and Tracks show Similar Efficiency

  9. Tractor Traction Technology • Singles, Duals, Triples? Triples Reduce Efficiency

  10. Tractor Traction Technology • Tracked Tractors • Less Slippage, Little Difference in Power Delivery • No “power hop” • Maintain Efficiency Over Wider Range of Conditions • Less Steering Control • Higher Costs Wheels Equally Efficient with 5% Wheel Slippage

  11. Tractor Traction Technology • Other Traction Issues • Soil Compaction • Least: Radial Tires with 7 psi inflation • Most: Tires with 24 psi inflation • Tracked Tractors Usually Leave Narrower Field Track than Tires • Yield Effects • Iowa State Study: Tires Reduced Yield

  12. Regular Maintenance • Periodic Engine Tune-up • Scheduled Filter Changes • Properly Adjusted Tillage Equipment

  13. Conservation Tillage • Fuel Savings From No-Till Fuel Cost/Acre1 1. ND Farm and Ranch Business Management Annual Report 2005

  14. Conservation Tillage • Strip Tillage

  15. Conservation Tillage • Strip Tillage Effect on Corn Emergence I Day Sooner Than No-Till

  16. Energy Saving Practices • GPS Guidance 5-10% Less Overlap

  17. Energy Saving Practices • Tillage Costs • Is the Operation Necessary? • Use Right Gear and Throttle Setting. • Proper Ballasting and Tire Inflation

  18. Energy Saving Practices • General Practices • Don’t Let Engine Idle Excessively • Use the Right Fuel • Match Tractor to Implement Size
