Which movie is this scene from?

Unfortunately, I only remember one scene from this film because I was very young when I watched it. So basically there's this teenage boy riding a tractor harvesting crops. He falls off the tractor and gets seriously injured by the harvester. A teenage girl witnesses this and runs home to tell her dad. Upon hearing the news, the dad gets in his truck and drives through a fence to get to the boy. When he returns all he does is look down and shake his head. The girl then starts crying hysterically because she knows he has died. I think the girl and boy were friends or maybe were in a relationship. Does anyone know which movie this is from?
