It's a wind-up!

A frustrating day at work, could have been ploughing but my tractor was recalled for an update on its turbo. Should have been completed yesterday while it was my non-working day, but didn't reappear until just before clocking off time, by which time the rain had returned.
This (the above) was meant to be for my AYWMC board which is "shadows" but ended up as all I photographed today. The shadow cast by a trailer jockey wheel handle hence the cryptic title ;0)
