My biggest problem was that the turned turf and soil quite often didn't turn completely over and fell back in the furrow. This had the result that when I ran down the furrow with the next pass the turf didn't have a furrow to fall into properly and it happened all aver again. Here is a video of my first attempt:
In hindsight this was probably because the field had never been ploughed before so I am not too disappointed, what I shall do is to wait a few days for it to dry a bit in the sun then flatten and break it down with the rotavator attachment, I may well plough it again then and I suspect that the second time I won't have the same problem.
The end result
Of course if anyone reading this can tel me why some of it was falling back into the furrow I would love to hear from them..
