Total diesel use for all field operations, including tillage, planting and harvest, is typically four to six gallons per acre.
Fuel savings are in addition to savings on wear and tear on machinery and labor requirements.
When tractors are used, Hanna advised paying attention to several key points to minimize fuel consumption. Tractor engines and transmissions should be well maintained. Make sure inflation pressure in rear and front tires is correct for tractor axle loads. For mechanical front-wheel assist tractors, closely match front tire size with rear tire size as detailed in the operation manual. Although well-maintained diesel engines are efficient, if possible match tractor horsepower to the required load or task.
