We switched from cans to a bulk tank in the late 50's.
I saw a can with the year 1982 or 84 stamped in it in that video. I was born in 83 but i have one vague memory of a milk can hauler (they all did it by tractor back then, so they could exit the tarpaulin cab from behind and walk over the drawbar to the wagon)
I can still recall the milk hauler that came and got the cans. He would bend over to reach down in the water bank can cooler...
So they put the cans in cold water on the truck, or at the farm ? I remember my father telling they put the cans on a rope in the water pit on sunday when the hauler didnt come.
All day long, I'm just glad we went to the bulk tank before I would have been expected to handle many cans every day.
Watching that Heino Krause video, thought oh my!, there was a guy whose job was "milk can tipper" at the factory... Back then, everybody had a job. Nowadays lots of challenged people end up in the social system because they cant find a job in this knowledge driven economy...
Double 6 herringbone parlour in the mid 60's what a step up.
Here, from the early 70s onwards, there were subsidies on freestalls and milking parlours, instead of the traditional stalls with a one foot deep muck gutter behind the cows. Halfway the 80s we got a milk quotum because farms were producing more than the market could bear.
In my area with lots of small fields separated by fencerows, the scale increase lagged 10 years behind other provinces with large open spaces, and probably too on replacing the milk can with the bulk tank... I havent asked any oldtimers from Friesland so i dont really know..
