Describing the moments leading up to the collision on Wednesday afternoon, the 58-year-old architect said after their meal, he had gone to see a colleague nearby while his wife and daughter walked to a shop.
“We split up for a short time and then the next thing my name was being called out by a stranger.
“There was my wife on the floor and my daughter just yards away on the floor and there was blood all over.
“There were these amazing people who just came to help. It must have been so hard for them because of the horror of it all.”
Mr Rogerson said the impact of the collision had catapulted Izzy into some metal railings and that one of the spikes had penetrated her eyelid.
Meanwhile, his 57‑year‑old wife, a teacher at Ampleforth College, was trapped under the tractor by her leg.
