When I was learning to use machinery I was always taught that a FEL was one of the most dangerous implements because you do not really think it is dangerous. With a mower, or a chipper or anything else with blades you can see how it could hurt you. However, a new tractor owner might not realise the implications of raising it up high on a slope and tipping the tractor over or raising it too high and rolling things on to yourself. The article does not say how experienced the woman driving was or what sort of tractor was being used. It would be interesting to know. Perhaps a good practice when using a FEL is always to keep it as low to the ground as you can. A good reminder to always work safely.
