[AJD] How deep to plow?

[Louis R Godena]

Hi folks;

It's been awhile since I last wrote, so sort of touching base.  Anyway, last
weekend was doing some fall plowing of my garden and an adjacent buckwheat
field (about 2 acres) with a 1926 JD model 41 14" plow and my overhauled 48
B.  I seemed to be listing precariously toward the furrow and, when I
measured how deep that furrow wall was, I discovered it was 18+ inches.
That's sort of deep isn't it, or is it just my imagination?  Anyone
routinely plow deeper than that?
