Tractor Traction Technology
  • Bias or Radial Tires?

Radials 5–7%

Advantage

Michelin Agricultural Tires

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
tractor traction technology7
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

Tractor Traction Technology
  • Singles, Duals, Triples or Tracks?

Duals and

Tracks show

Similar Efficiency

  • Singles, Duals, Triples?

Triples Reduce

Efficiency

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

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
regular maintenance
Regular Maintenance
  • Periodic Engine Tune-up
  • Scheduled Filter Changes
  • Properly Adjusted Tillage Equipment

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

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