Two workers on a farm were doing maintenance on a forage harvester in preparation for cutting grass. The harvester, with its chopping or grass head attached, was hooked up to a tractor. One of the workers was in the tractor with the engine idling. The driveline connecting the tractor engine to the harvester—known as a power take-off (PTO)—was rotating. The rotating PTO meant that the chains on the harvester and grass head were also turning. The other worker was spraying grease to lubricate these chains when his coveralls got caught in a small rotating shaft, pulling him around it. The worker suffered serious crushing injuries.
