I have never been to Norway - just MANY pictures of grandparents farm. Some of the pictures look like post #4. Makes my whole body ache to think of all the time it must have taken to clear the fields. Grandparents farm dates back to VERY early days - many, many generations of young adults to help clear the fields. The farm finally purchased some type of tractor around 1965 to help with the farm. Prior to that it was manual labor and oxen or whatever. The original ways worked for so many generations and a tractor can be a tremendous expense on a farm.
I think it is also - some of the new, modern way simply do not adapt to rural farming types.
