PETALUMA (KRON) — A grass fire that threatened a home in Petaluma on Sunday afternoon was caused by a lawnmower.

On Sunday around 4:15 p.m., residents near Rovina and Jacquelyn lanes reported a grass fire in the area, according to Petaluma Fire Department.

Firefighters arrived on scene to find a half-acre fire threatening a nearby home located on Jacquelyn Lane and a radio tower located in the middle of the field, fire officials said.

Firefighters were able to use hose lines to quickly extinguish the fire before it reached any structures.

The fire burned approximately one acre of grass.

No injuries were reported, according to fire officials.

The nearby house on Jacquelyn Lane sustained damage to its fence, outdoor play equipment and shed. Fire officials estimate the loss to be worth approximately $2,000.

Investigators determined the cause of the fire was due to a riding lawnmower that had struck a rock in the dry field. As the air was warm at the time and there was a steady breeze, the weather conditions helped ignite the fire, according to fire officials.

Firefighters advise residents to mow their lawn before 10:00 a.m., when temperatures are not as high, and to never mow their lawn when it’s windy.Bay City News contributed to this report.
