A farmer friend of my dad had a large dryland farm, and decided to hook two tractors together. He removed the front wheels from each, connected the back tractor to the hitch of the front tractor, linked the throttles together and had a double-size tractor, with four high-traction wheels. Hydraulics from the front tractor were used to steer the tractors.
This same fellow built a developing tank for b&w movie film, and did a lot of time lapse photography. This is on a farm in Montana in the 1960s.
He built a jig to help build these for other farmers who wanted them.
Later, Case and other manufacturers populated the dryland farms with something that looked very similar.
What many people do not realize is that rural farm america has had a more thorough impact on daily life by technology than any other segment of life. From the beginning of my grandfather's generation through the end of my father's generation saw a nearly two orders of magnitude improvement in productivity. Every aspect of daily life was affected.
"Busy farming" in our life meant plowing the fields, seeding, harvesting, which involves machinery, or in my grandfather's generation horses. Everybody had a shop, which included torches, electric and acetylene, a wide range of tools. Something breaks, which it often does at the worst possible time, you generally fix it. Changed plugs in all your vehicles, gapped the plug, points, changed the oil, put in a new head gasket. During family get-togethers, my Dad and Uncles would sit around while waiting for dinner figuring out how to make something work better. Innovation is part of farming.
So the headline is wrong, the article is wrong, and the quote it points to is wrong. Some of the comments do offer some correction. And apparently there is a bit of "Blub" phenomenon going on with what does "Busy Farming" mean.
