Each time we went to land we passed a field with this machine in it. It looked like an abandoned piece of junk from a distance but every time we passed the field I swear it had moved from one side to the other and yet we never saw anyone near it. I decided that rather than a piece of agricultural equipment it was really a ghost machine and once it got dark it moved itself up and down the field in the moonlight. I later decided that it was probably a space probe and moved around to get better communication with the mother ship.
Ian had a much more practical explanation and said it was a thresher cutting strips of hay for animal feed. I like my explanation better!
Ian is quite keen on agricultural equipment and we could not go past a tractor shop without a stop while he had a 30 minute conversation with the owner about the price of tractors and toppers. I used it as an excuse to sit in the van and sleep! I did notice however that he was not the only man looking lustfully at large pieces of equipment!
