6. Managing Fuel Costs: Limit Usage – Easier Said than Done Limit Usage – Easier Said than Done Major Fuel Usage in ND is in the Fall. Harvesting and Tillage. Major Fuel Usage in ND is in the Fall. Harvesting and Tillage. Buy Large Storage Tanks and fill when prices are lowest – This costs a lot of Money Buy Large Storage Tanks and fill when prices are lowest – This costs a lot of Money

7. Managing Fuel Costs: Use Futures and Options to lock in Price. Can be Risky. A Future contract is 42,000 gallons. Farmers may need to work together. Use Futures and Options to lock in Price. Can be Risky. A Future contract is 42,000 gallons. Farmers may need to work together. Lowest Fuel Price is usually in Dec. or early January. Lowest Fuel Price is usually in Dec. or early January.

14. Radial and Bias Tires A properly Ballasted Radial will usually be 6% to 10% more Efficient Than a Bias Tire. A properly Ballasted Radial will usually be 6% to 10% more Efficient Than a Bias Tire. Radials can Operate at Tire Pressures Down to 6 psi. Do not Operate Bias Tires Below 14 psi. Radials can Operate at Tire Pressures Down to 6 psi. Do not Operate Bias Tires Below 14 psi. Do Not Exceed the Load Carrying Capacity of a Tire at the Selected Tire Pressure. Follow the Tire Company Load Charts. Do Not Exceed the Load Carrying Capacity of a Tire at the Selected Tire Pressure. Follow the Tire Company Load Charts.

15. Radial and Bias Continued Increase Tire Pressure if Mounted Equipment is Carried on the Tractor. Increase Tire Pressure if Mounted Equipment is Carried on the Tractor. Soil Compaction will Decrease at Lower Tire Pressures. Soil Compaction will Decrease at Lower Tire Pressures. Tires Should Slip Between 8 and 15%. Four wheel drive tractors will usually be at the low end of the slippage range. Tires Should Slip Between 8 and 15%. Four wheel drive tractors will usually be at the low end of the slippage range. Check Tire Pressure Regularly. Check Tire Pressure Regularly.

16. Tracked Tractors Slippage is Usually near 2%. Slippage is Usually near 2%. Power Delivery Efficiency is Equal to Tired Tractors. Power Delivery Efficiency is Equal to Tired Tractors. Turning may be more Difficult for Tracked Tractors. Turning may be more Difficult for Tracked Tractors. Tracks Produce a Narrower Print in the Soil. Tracks Produce a Narrower Print in the Soil. Soil Compaction is about equal for low pressure Radials and Tracks. Soil Compaction is about equal for low pressure Radials and Tracks.

17. Soil Compaction of 4 WD and Tracked Tractor Under Various Loads Ohio State Tired tractor had the highest and the lowest soil compaction. An 8870 JD - 350 hp. Tire pressures were 24 psi and 7 psi. Tired tractor had the highest and the lowest soil compaction. An 8870 JD - 350 hp. Tire pressures were 24 psi and 7 psi. Two Cat Challenger tractors, a 65- 270 hp and a 75- 308 hp caused soil compaction loads between the two tired tractor tests. Two Cat Challenger tractors, a 65- 270 hp and a 75- 308 hp caused soil compaction loads between the two tired tractor tests. Operating radial tires below 10 psi can reduce pressure on the soil. Operating radial tires below 10 psi can reduce pressure on the soil.

18. Iowa State University Studies Corn yields have shown significant increases when tillage passes were done with a tracked tractor. Corn yields have shown significant increases when tillage passes were done with a tracked tractor. The soil pressure under the tracks were about 3 and 6 psi. The soil pressure under the tracks were about 3 and 6 psi. Soil pressures under the tired tractor were near 16 psi. Soil pressures under the tired tractor were near 16 psi.
