Both at fault.
Tractor/ fastrac ? driver going too fast, should have pulled into that wee lane on the left, was he empty ? think so by the way he stopped pretty abruptly.
Bike rider driving a city boy attitude in a country environment. He saw that land rover miles away, he could easily have stopped in time, if he couldn't, he should have jinxed up thon wee lane.
You have to remember, these fastracs can fairly motor on, not like the days of the wee grey fergie
