Sun rake

This image is of part of a machine that had been put out to pasture at the back of the cow paddock. A number of wheels such as this, attached to upright arms, create a startlingly geometric sight. What they 'really' are are rotating rakes which, when powered by a tractor's drive chain, gather two swathes of cut straw into one prior to it being gathered up for later feeding to the beef (and, eventually, you (if you eat cow)).
