Choose Correct Ballast
Choose ballast to obtain 10 to 15% wheel slip. Use no more ballast than necessary, reduce ballast for light work.
Select Correct Gear
Always drive in the highest possible gear with reduced engine speed. Choose a gear so that engine speed (A) with engine not under load drops 150 to 250 rpm when the tractor is operating and the engine is under load (B).
NOTE:
For light work, reduce engine speed below 2000 rpm. Select a gear so that engine speed drops 200 to 300 rpm when load is applied.
