Porsche tractor with bale loader at Wilcoxholm

John Kerr Wilcoxholm Farm, Linlithgow with his own invention of a bale lifter to self load Allis Chalmers rotabaler bales on to the trailer. As his neice Rae Anderson is driving the tractor throughout the film, we only see it in action at the very end. James (Jimmy) McIntyre is on the trailer setting the bales.
The tractor being used is a Porsche bought from Gillies & Henderson new.
I think he would have been the first man in West Lothian to own a Porsche!
Around 1962.
