Shallow plowing in low gear, yes it'll probably handle 2-12's in some soil conditions, especially today if the engine is in good condition and burning gasoline. As always, there's a ton of variables in play, including, but not limited to (desired) speed, depth, tire size (or steel/rubber), soil types, bottom type/share type, and more.
Even today, I'd personally rather have a single-bottom and not work the snot out of the tractor, and have the potential for some added depth or speed (2nd. gear would make the acres fly by :lol:). It is possible cover as much ground or more with less width of plow in the same amount of time.
As far as "period correct" moldboard plows, mounted one bottom one-way (#90, "quick-attach" or not, hand, clutch, or hydraulic power lift) and one bottom two-way (#86 hyd. power lift) plows were available with 12-18" bottoms.
#8 Little Genuis one and two bottom and #2 Little Wonder 2-10"/12"/14" pull-type plows were available when these tractors rolled off the line. The #37 Two-way pull type plow being 1-16" is a possibility, too. There were also specialty plows designed for vinyard or orchard use. The #4 Genius Plow could be had in 2-10's or 12's, and the #24 orchard/vinyard plow was available as 2-12/14's.
The #3 Wonder/Little Wonder/Tractor plow (1-14"/16") and the #4 Wonder/Little Wonder/Tractor plow (2-10"/12"/14") both came out in 1940, and the earliest of these could certainly have been on dealer lots while the very last of the F-14's were there.
Also, anything deeper than about 5 or 6 inches was considered "deep tillage" when these were new. Most bottom styles at the time were meant for slow speeds.
