Stay Safe from Combine Fires this Harvest

By Scout Nelson

North Dakota State University (NDSU) Extension is reminding farmers that daily equipment checks and monitoring weather conditions are essential to prevent combine fires during the busy harvest season. With warm, dry weather across the state, the risk of fire in fields has increased significantly.

Farm and ranch safety specialist Angie Johnson explains that a spark from machinery failure can quickly ignite crops or residue, especially when conditions are hot and dry. Soybean and dry bean harvests are underway, with corn and sunflower harvests soon to follow.

According to the North Dakota Agricultural Weather Network, late September temperatures were 8 to 10 degrees above average, creating a higher fire risk.

“Equipment fires, specifically combine fires, are a serious threat during the harvest season,” says Johnson. “No one wants to lose their combine or the remaining unharvested crop in the field due to fire. The biggest risk, however, is the loss of human life, as combines, crops and other equipment can be replaced – you cannot.”

Farmers are advised to conduct daily inspections of electrical and hydraulic systems, ensuring wires and hoses are secure and free from damage. Cleaning the combine daily is also crucial, as soybean dust and chaff can easily ignite.

Additional safety tips include:

• Use an air compressor or blower to remove crop dust and residue from high-risk areas.
• Check bearings and wiring for heat buildup or wear using an infrared thermometer.
• Carry two fire extinguishers, one inside the cab and one on the exterior.
• Avoid harvesting during extreme fire danger or windy afternoons.
• Keep a water truck nearby and park equipment in low-vegetation areas.
• Inform others of your field location and schedule before harvesting.

Local fire Chief Rich Schock emphasizes early action: “If your combine catches fire, call the fire department immediately. Quick reporting helps save property and lives.”

“Even though it may feel like you are slowing down your harvest progress by stopping the machine to clean off chaff and dust, it could be the difference between finishing your harvest season or watching it go up in smoke,” says Johnson. “Do the best you can each day to keep your equipment cleaned and maintained. This will protect your investment and yourself from serious injury.”
