Why is it important to harvest crops in optimal conditions?
Harvesting your crops in optimal conditions can make your harvest more efficient. Crops that are too wet or soil that’s wet results in more fuel consumption, so by waiting until the conditions are just right, you save energy.
How to improve fuel efficiency?
The best way to keep a machine running well is to follow the instructions in the operator’s manual. For engines, fuel, oil and air filters should all be changed routinely according to the operator’s manual; keeping the engine lubricated and running smoothly improves fuel efficiency.
How to save on fuel on a tractor?
A great way to save on fuel is to use the smallest tractor that can do the job. Larger tractors usually waste more energy, so if you’re running a farm that produces a lot of different crops or needs to perform a lot of different field operations, having and using different sized tractors might be a good investment for you. Generally, small equipment shouldn’t be used with a big tractor. Using the most efficient combination of tractor size and equipment for your field operations could save you money in the long run. If you’re looking at buying a new tractor, or wondering which tractor out of the ones you already own would be the most efficient choice for a job, the University of Nebraska houses the Nebraska Tractor Test Laboratory (NTTL), which is the official tractor testing station in the U.S. for OECD (Organization of Economic Cooperation and Development), could be a really useful resource for you. Alternatively, the American Society of Agricultural and Biological Engineers (ASABE) has a spreadsheet that compiles NTTL Results for a more streamlined comparison. The performance data on the tractors tested by the NTTL and the ASABE Spreadsheet for Matching Tractors and Drawn Implements could help you find a combination that will most efficiently fit your farming needs and help you choose equipment that best compliments your machine’s capabilities
Is field operations efficient?
Are your field operations as efficient as possible? Or, could you be saving money by changing some aspects of your operation? In most cases, the answer is “yes”— your operations could be more efficient and you could be saving money .
Is deep tillage better than shallow tillage?
Deep tillage uses more fuel than shallow tillage and often isn’t necessary. There are options to save energy, like minimum, strip, or no-till, to reduce or completely rule out tillage. However, if you decide that tilling (to some degree) is necessary, to make the best use of your fuel and time, secondary tillage should be shallower than primary tillage. Secondary tillage should really only be ½ the depth of the primary till. This reduces compaction, lessens the amount of wet soil and weed seeds brought up to the surface, reduces water loss, and uses less fuel. With shallower tillage in general, water loss is reduced, leading to a longer period of time before irrigation is needed.
