A working model was built to aid in explaining the principles of tractor accidents on slopes. The main types of tractor accidents on slopes are stability loss (overturning directly) and control loss (sliding downhill, frequently followed by overturning). A summary of UK accident records over a number of years is presented, and illustrated by means of polar diagrams, which represent graphically the stability and control of tractors on slopes. The construction of the model and demonstrations for which it can be used are described. The demonstrations include the effects on stability and control loss of slope, heading angle, wheel grip, track width, fourwheel drive, speed, braking and trailed and mounted equipment with or without load.
