Aaron Scott has won second place in our simple category.

Tagging newborn calves in the company of cranky mothers is now a safer affair at Lilburn Estate in Wooler, Northumberland, thanks to the work of head mechanic Aaron Scott.

Such has been the success of his ATV-towed calf-catching crate that he’s now knocked up three of them.

It incorporates several neat features, including the ability to swing the towbar outwards from its central transport position and brace it offset ready to apprehend a calf.

Once it’s in the cage, the rider yanks a length of rope strung from the back of the bike to release the guillotine front gate.

Staff can then climb in to safely fit the tag, administer antibiotics, and complete any registration paperwork, the paraphernalia for which is stored in an on-board tray.

Should the animal need moving, it can be eased through an internal gate and into a floored section at the back.

The new metal, stub axles and hitch for each crate costs about £500, plus a day and a half of Aaron’s time.
