The equivalent for us would have been an old Twin City (iron converted to rubber) precursor to M-M excepting it was the flat ground beastie...the M's were the rowcrop versions.
From them the progress went thru the Farmall 400, then 560. That was the last Farmall; it had terrible tranny issues and then was when Deere introduced the 4000 series and Dad bought the first 4010 diesel and never looked back.
Had a parallel line of Allis-Chalmers; grandfather had bought a little WD-45 in mid 50s when he was getting where the M's were a little more than he wanted to handle. Had a whole line of the "quick-tach" proprietary 3-pt system implements with it. In '58 had first really good wheat crop after the dry 50s and Dad updated it to a D-17 as well as getting wheatland Case 930 and the aforementioned 4010. I put a zillion hours on that D17 doing rowcrop with it...my brother hated the row crop because had to pay so much attention to drive straight rows -- we were listing 4, knife-sledding/cultivating 6 and cutting 5 at the time so a bad spacing meant a lot of lost crop. :) I, otoh, hated the boredom of just going 'round 'n 'round in a square on the wheat ground! :)

Eventually, of course, everything got much bigger and the D-17 became the utility tractor. It was pretty ideal for the time with low/wide wheel base and a loader. It's the one besides the old Cat 22 I wish had one of for collection/nostalgia.
Never understood that one, really? Purpose? Need? Be awfully tough on something like 60 circles on 20" rows with 25-30,000 plants/A.
Being all dryland, only corn we ever grew was a small sweet corn patch that might (or might not) make any roasting ears depending on the year and whether it rained at right time or not...
