A DISCUSSION OF TRACTOR OVERTURNING ACCIDENT ON SLOPES DUE TO STABILITY OR CONTROL LOSS

The causes and prevention of tractor overturning accidents on slopes were reviewed with reference to case studies. The majority of overturning accidents are due either to stability loss, when the tractor overturns directly, or to control loss, when the tractor slips out of control before overturning. A number of overturning accidents are described, and the reasons for stability or control loss are explained using polar diagrams. The principal factors responsible for the accidents are ground factors, including slope, roughness and surface conditions, the way in which the tractor is driven, including heading, speed, acceleration, cornering and braking, the equipment, including the tractor and mounted or trailed machinery, and the load carried, which is particularly dangerous when it changes continuously during work. Means of preventing tractor overturning accidents are proposed.
