Timely maintenance helps prevent baler fires

Parts of the Midwest are experiencing abnormally dry to moderate drought conditions, while other areas have been receiving adequate rainfall. Regardless of moisture conditions, baler fires are still occurring.

“It seems odd to think about the risk of baler fires right now, as the grass is still green in many areas where hay is still being harvested,” said Tom Clays, North Dakota Forest Service director. “However, the amount of ‘fuel’ or biomass out there in the ditches, meadows and Conservation Reserve Program areas is substantial this year. There’s enough ‘fuel’ out there that can easily catch fire with just one spark and quickly become out of control.”

Timely baler maintenance is key to preventing dangerous baler fires.

Angie Johnson, North Dakota State University-Extension farm and ranch safety specialist, said, “A common cause of baler fires is mechanical issues, primarily problems with roller bearings found within the baler. The roller bearings inside the baler can easily become damaged due to wear and extended use.”

Once the bearings are damaged, they become dangerously hot and can start a fire inside the baler chamber.

As the haying season shifts into more mature and drier grasses, including the baling of small grain straw, those types of fuels can burn quickly and spread over a large area.

“We have to remember that there is a tremendous amount of friction and static that is building up during baling. Add that combination of friction and static electricity or a mechanical failure on the baler with extremely dry hay, and you have the perfect recipe for a fire,” said Johnson.

To prevent baler fires during haying season, Johnson recommends conducting a visual assessment by walking around the baler when both the baler and tractor are shut off. Performing preventative measures, including daily maintenance when in active use, can help producers maintain their equipment for peak performance, reduce repairs and prevent equipment fires.
