I have been a hand milking Nubian goats for many years, but with 5 heavy milkers, I hoped to save my hands. I also wanted a way to help anyone who may take over for me. The only thing that is a hindrance with this milk machine is that you have to release the vacuum by pulling free a tube from the pump. It can take me longer than I would like to do that. I will try using a lube like petroleum jelly to make it faster.
