DERRY — A farm tractor rolled down an embankment off Warner Hill Road Monday evening, landing on its roof and trapping the operator, who was suspended in her seatbelt when rescuers found her.

Derry firefighters were dispatched to the scene at about 6:19 p.m. after getting a 911 call for the occupant trapped in the cab of the tractor.

Upon arrival crews found a medium-sized farm tractor had rolled down a steep and soft embankment. The operator was spared serious injury because she was wearing a seatbelt and the tractor had a roll bar.

The operator was partially suspended by the seatbelt, but crews were able to remove her from the tractor. They then hauled her up the embankment using a stokes litter, or rescue basket. The operator was taken to Parkland Medical Center with non-life threatening injuries.

The cause of the accident is under investigation. There was no damage to property and no significant damage to the tractor, according to the fire department. There were also no injuries to rescue personnel.
