widest tandem disc up to 1950

I think if you check into manufacturers across western US and Canada, you will find many large implements never seen in most of the major manufacturers sales literature. I think even as far back as 1912 you could see 24' disk harrows and 18 bottom plows on the prairies. Most of them pulled at very slow speeds by those monster 2 cylinder tractors from that era, and later crawlers. There is a photo of a 55 bottom Oliver plow at Winipeg being pulled by 3 - 45 hp Mogul IH tractors in 1912. Not too wide a bottom it only plowed 64 feet at a pass. There are many photos of these tractors each pulling 18 bottom plows. I think if you check into the history on the prairies you will find a good many locally manufactured disks in the 20 to 30 foot range, even as far back as 1920.

I might be all wet here, but I don't think they even made tandem disks back then.

Do you mean double ganged disks? A 10 footer was a big disk in those days.

How did they get the hydraulics to work on those horse drawn implements?

I guess I've never ran across one of those.
