Today's 'Sakal' (the indispensable Marathi daily for Punekars) has an interesting news titled translated as "cleaning machine for cows" (page 3 of the main paper). The cow's expression of pure enjoyment is what caught my eye.
With some help from Google search (who else!) I located this Daily Mail article dated 22 July 2010 published online here (http://www.dailymail.co.uk/news/article-1296609/The-cow-wash-How-automatic-brushing-machine-improve-milk-production.html).
The article describes how the cow wash designed by DeLaval helped improve milk production while obviously keeping cows happy!
Wow! This is truly spreading benefits of mechanisation to all!
