The Albany Democrat-Herald reports that 14-year-old Haylee Smith and 16-year-old Hannah Smith's action allowed their father, Jeff, to wriggle part of the way free and get breathing room.
Smith says he was pulling a stump from his garden on April 1 when the tractor flipped. The steering wheel pinned his chest to the ground.
He says he was losing breath with each scream, but his daughters heard and ran to him.
A neighbor finished the job by using his own tractor and its shovel to lift the Smith's tractor and allow Smith to get his arm out.
Smith was treated for a broken left wrist and other injuries.
