Ollie 25 year ago maybe more ,when col and pete massey used to plough with 4255 and 7 and cols 49 ,with 9 on back those two where like clockwork and perfection , and apprentice with 5 doing short headlands and garings ,In this is video the driver isn't hanging around on his headland turns- he turns at heck of a rate of knots but does so with the plough left lowered down, he doesn't actually turn it over until he is heading in reverse far more gently, it's up and over in a flash before he starts turning dead sharp and fast again.
