Adair CO Extension Agent, Agriculture: Farm equip fuel economy tips

Color of smoke and temperature of engine determines diagnoses; bio-diesel can save money, but there are special problems to overcome

With the escalating cost of fuel, producers must look for ways to reduce their usage. One good place to start is eliminating unnecessary trips across the field. No-till production, already popular in Kentucky, may become even more popular as farmers look to economize.


Besides eliminating usage, proper equipment maintenance and operation is critical in getting the best fuel efficiency from farm equipment. Here are some tips that can help farmers get the most from their fuel.

Air and fuel filter maintenance is important to get a correct air-to-fuel ratio for proper combustion. Air filters need to be cleaned or changed regularly to ensure they are not restricting air flow and starving the engine of air. Fuel filters need to be replaced as they age and become clogged and reduce fuel to the engine. Checking these on a regular basis can mean substantial fuel economy.

White smoke from a tractors exhaust when it is cold or black smoke when the engine is warm are symptoms of a problem, and farmers need to consider what the source of the problem might be. A fouled injection system could be the culprit.

Injectors introduce fuel to the combustion chamber and if the fuel is not broken up properly into small particles by this system, the combustion process will not be complete. As with all equipment, check the manufacturers recommendations for service.

Match the tractor to the implement. Make sure the tractor is big enough to pull the implement. An implement that is too large for the tractor can seriously compromise fuel economy. Also, make sure the tractor is properly ballasted weight is evenly distributed between the front and rear.

Tire pressure can impact fuel use

Tire pressure can also impact fuel economy. It is important to keep tire pressure within the manufacturers recommendations, but by using the lowest possible pressure needed to support a load you also receive the best fuel economy. The more the tire spreads out and leaves a footprint on the ground, the better the fuel economy. Tire pressure and ballasting go hand-in-hand.Another way to conserve diesel fuel is gear up/throttle back. If a producer is using a tractor larger than is necessary for the job, it is better to slow the engine down (throttle back) and increase the gear to get the needed ground speed.

Some farmers may also be considering the use of alternative fuels such as biodiesel. It can be a viable option and many manufacturers warranty their equipment if it is used. Be sure to check this before making the switch.A producer may have to change his fuel filter as many as six to 10 times when making the switch from petroleum diesel to biodiesel. Biodiesel will partially dissolve a paraffin layer that is in the tank as the result of petroleum diesel usage.

Another factor to consider when making the switch is that biodiesel will jell as temperatures drop more quickly than petroleum diesel. Farmers need to understand this and take measures to avoid problems during cold weather. Processors are working to resolve this concern.

Finally, try to minimize idling time. While some idling time is necessary to warm up and cool down the engine, dont go to lunch and leave the tractor running.
