Energy Efficiency: Field Machinery Operation

This guide provides farmers and agricultural professionals with practical strategies to enhance energy efficiency in field machinery operations. It covers key topics such as fuel usage, tractor traction technology, regular maintenance schedules, and energy-saving practices. Specific fuel consumption estimates for various equipment types, along with maintenance recommendations, are detailed. The document also explores the benefits of conservation tillage, proper tire selection, and the role of GPS guidance in reducing overlaps, ultimately leading to reduced fuel costs and increased operational efficiency.

  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
