Nice video, for sure. Back then, though, tractors WERE less safe because they had no ROPS, seatbelts, or turn signals. But one crucial piece of advice still holds true- you need to use your head when you're operating any kind of construction or agricultural equipment.
At 5:21 it looks like one helluva storm about to"cut lose".Safe tractor handling is to not be in the field in the first place when the sky looks like that.
The end of the safety video is punctuated by the driver's necktie sailing free in the wind - better hope he never has to get near a rotating part that will grab the tie and wind him up.
