There is a tool box in the cab. You locate a plastic newspaper bag that you use as a glove to prevent fingerprints. You open the tool box and there's a hammer in there. You swing into the farmer's head over and over again as the strains to get at you. Finally his head cracks open and not long after the punishing blows still him. It took so much to kill the man! Whew! You sit in the field awhile to catch your breathe and get yourself together. You don't know it, but you just prevented a massive zombie outbreak that would have taken your life.
