is there such an expression as "down to the narrow rows"?

Are you thinking perhaps of the phrase ?down to the short rows??

I?ve hear this phrase, which is used to describe the nearing of the
end of a hard task, all my life. I cannot be certain but I suspect it
is agricultural in origin. If you imagine a garden plot that is not
square, at one end the rows would be shorter than at the other end. If
you were planting, or weeding or harvesting for example, it would be
wise to begin on the side where the rows were longest because in the
beginning you are freshest and full of energy. Getting to the short
rows then would be nearing the end of a very difficult job.

Does this work for you as an answer?

I was hoping that someone else, besides me, had heard or read "narrow
rows" as opposed to "short rows."  I believe that your explanation of
the latter is exactly correct, and I have heard the expression used
that way.  Thanks.

My grandpa, who operated a small family farm, often used the phrase
"down to the short rows" to mean "nearing the completion of a
project."

When farmland is irregularly shaped rather than perfectly rectangular,
this leads to there being long, even rows in the center of the plot,
and shorter rows at the outer edges. Typically the long rows are done
first, and the short ones last.

I have never heard (nor can I find any reference to) "down to the narrow rows."
