Emporia and rural firefighters battled a smoky fire about five miles west of Emporia on Friday.
Originally, the call to 254 Road 180 was for a barn fire. Emporia Fire Battalion Chief Rex Fisher says the fire looked worse when firefighters arrived than it actually was.
It's unclear what started the fire in the lawnmower. There was minor fire damage to a wooden support beam inside the barn, with some fire marks both inside and outside the structure.
No injuries were reported. Mike Myers owns the property.
