Take a look that this site: Winnindoo, the dairy farm of Max and Evelyn Warren in Victoria, Australia. They are using Lely milking robots for pasture-grazing cows. They were the first 100% pasture-based dairy farm to install robotic milking systems. They began with Lely A2s and have now installed four A3s.
The site gives a lot of information about the farm's operations and production experience. But perhaps the most poignant comment on the site from Max and Evelyn is this:
"We made the conscious decision to remain dairy farming well into retirement age as opposed to lounging on a beach somewhere up north. The robotic milking system allows the older farmer to maintain total involvement with a reduced need for the high levels of physical input normally required. We see that automatic milking systems will extend the possible working life of dairy farmers."
