A farm tractor operator failed to fold the side booms and struck an oncoming car.  The deputy said last month 31-year old Pete Treml of Mauston had pulled onto Highway 58 near Steiner Road in the Town of Lindina and did not fold the booms towards the farm machinery.  As he raised them, they scratched to top of an oncoming Toyota car being driven by a LaValle woman, 58-year old Colette Skundberg-Radtke.  No one was injured.
