Dinky is Book Four of The Green Machines, the children's picture book series by David Woods about helpful vehicles with big personalities in the village of Little Muddlebury.

Dinky is the smallest of the Green Machines, and he can drive backwards just as fast as forwards. On the day of the Harbour Fair, Mayor McNeil puts him at the front of the convoy as its scout. When a sea mist rolls in and the lane fills with Farmer Geoff's sheep, going backwards turns out to be exactly what is needed. Then, at the prize-giving, somebody shouts that Dinky is not a real Dingo at all.

  • Reading age: 4 to 8
  • 32 pages, square format (146 x 146 mm), illustrated in colour throughout
  • Written by David Woods
  • Friends in this story: Foxy, Mac, Andrea, Sandy, Bertie, Morris, Old Charlie, Quack
  • Ends with a page of true facts about the real vehicle
  • One duck hides in every picture for children to find

Real Dinky is a copy of a Daimler Scout Car, which soldiers nicknamed the Dingo. Real Dingos were built in Britain between 1939 and 1945, and 6,626 were made. A Dingo has five gears forwards and five gears backwards, so it really can drive as fast backwards as forwards.
