Usually farmers like to have dry weather in the fall to get the crops out of the field – just not too dry!
Harvest season two years ago was so wet that crops in some areas went unharvested until the following spring. This year is a totally different story. Combine fires setting fields on fire have been happening all over the corn belt this season because it has been so dry and windy, the worst areas being Iowa, Nebraska and the Dakotas.
“Extreme conditions in South Dakota this fall created a perfect storm of high temperatures, low humidity, dry crops, and high winds producing extreme risk of fires during harvest,” said Daniel Humburg, professor of Ag & Biosystems Engineering Department at South Dakota State University.
There is still plenty of harvesting yet to be done and while most farmers understand the risks of combine fires and how to prevent them, a little reminder never hurts. University of Nebraska farm safety specialist Dave Morgan offers these safety tips:
– Keep your equipment clean and in good repair. When you get done for the day, take time to clean your machine thoroughly with an air compressor, power washer, or even a broom to dislodge any crop residue or chaff from the combine.
– Fix any fuel, hydraulic or oil leaks. When it’s this windy, vegetative matter breaks up into really fine material that readily accumulates on oil and fuel leaks, Morgan said. This creates a source of solid and liquid fuel. From there, it doesn’t take much to start the fire — a dry bearing or a slipping belt can quickly heat up or spark.
– Check fluid levels and carefully refill, being careful not to spill any oil or fuel on the equipment. But don’t overfill fluid reservoirs. With high temperatures in the mid 80s, oil expands and may “burp” out the vent, creating another fuel source for fire.
– Carry at least one, and preferably two, fully charged 10 lb ABC fire extinguishers on all equipment. (Be sure to have your fire extinguishers inspected annually and refilled as necessary).
Let’s be careful out there!
