Fire Safety During Harvest

Wildfires can spark at any time, especially when crops are dry and rainfall is scarce. Fires cause millions of dollars in property damage, including machinery, crops, and time. Although, keeping farmers safe is always the top priority.

Modern combines are powerful machines, which means they can produce excessive amounts of heat. All it takes to start a fire is a high-temperature source to ignite a dry crop.

Prevention steps:

Constantly check the engine temperature gauge
Keep the machine clean, especially around the engine
Frequently check air filters to help the engine run cooler and more efficiently
Check coolant and oil levels daily
Check pressurized oil supply line to the turbocharger for areas that rub and may start an oil leak
The U.S. Drought Monitor has released data that parts of Illinois range from abnormally dry to severe drought
Research from South Dakota State University suggests that if we have dry conditions and start experiencing wind speeds close to 30 mph and above, fires may be inevitable. During these periods producers should consider delaying harvest until evening hours when winds decrease or wait for precipitation. Higher humidity levels may also reduce the potential for field fires to spread.
It is recommended to have two ABC-rated fire extinguishers on hand: a smaller 10-pound unit in the cab and a larger 20-pound extinguisher at ground level on the combine
Ensure all emergency contacts are updated and shared with the harvest crew

Safety tips:

Some newer combines have fire or heat sensors in the engine bay and will trigger an alarm
In case of fire, turn off the engine, get away from the machine, and call 911
Use fire extinguishers if it is safe to do
Fires can double in size in less than a minute, embers can spread easily and start new fires

Create an emergency plan:

Harvest crews should discuss a plan for what to do in case of a fire. Discuss when they should put out the fire—shoveling dirt, using a fire extinguisher, flour, sand. If the fire is spreading quickly, it is too hot, and threatening safety, evacuate the area immediately.

Keep in mind that personal safety is far more important than property loss. Attempting to fight a fire should only happen after calling 911 and determining that it’s safe to do so. Fire prevention is possible; it just requires some regular maintenance and keeping equipment clean.

Learning to See the Soil Differently: Dan Sanderson’s Conservation Journey (Part 1)

By Tara Desmond • October 30, 2025

When northern Illinois farmer Dan Sanderson started farming in the 1980s, cover crops weren’t exactly mainstream. Government set-aside programs required planting something like oats, but what stuck with Dan wasn’t the paperwork. It was the difference he noticed in those acres the next year—healthier plants and stronger soils. Decades later, that observation led him down a lifelong road of conservation and soil health improvement. In this episode of IL Corn TV, Dan joins IL Corn board member Shane Gray to talk about his path toward regenerative farming, what he learned at a 2017 Soil Health Academy that changed everything, and why he now treats soil as a living system, not something to manipulate. Dan’s story is one every farmer can relate to—trial and error, lessons learned the hard way, and realizing that “good soil” is about more than yield. 🎥 Watch Part 1 now and catch Part 2 soon, where Dan dives deeper into how he’s reducing inputs, improving soil function, and still keeping his yields strong.
