A City and County worker was uninjured after a riding lawnmower he had been operating went up in flames Wednesday at Kapiolani Park.
Large flames and a huge plume of black smoke billowed up from the lawnmower.
Honolulu Fire Department spokesman Scot Seguirant said the fire was reported at 8:22 a.m. and two units responded.
Firefighters arrived in seven minutes and had it extinguished at 8:36 a.m.
Seguirant did not know the circumstances preceding the fire or the cause.
