Rachel Numan lives on a dairy farm in the Waikato, with two tiny farmers (her boys, Jack and Oscar), one real farmer (her husband, Chris), and one pretend farm dog (who is a little bit scared of cows). 

She is a trained veterinarian, but these days spends more time trying to find matching socks and drinking lukewarm coffee than she does fixing cows.  

Tractor Dave is her debut book - based on a little 1983 David Brown tractor she and her husband own.  Sure to be a hit with machinery lovers big and small, it is packed full of all the best parts of maize harvesting day on the farm.
