I am not sure if it was a Stan Rogers song called "Field Behind The Plough" but I include the lyrics in case it is. (They are not in the DT)Yours, Aye. Dave.

Watch the field behind the plow turn to straight dark rows
Feel the trickle in your clothes, Blow the dust cake from your nose
Hear the tractors steady roar, Oh you can't stop now,
There's quarter section more or less to go.

And it figures that the rain keeps its own sweet time
You can watch it come for miles, but you guess you got a while
So ease the throttle out a hair, Every rods a gain
And there's victory in every quarter mile

Poor old Kuzyk down the road
The heart-ache, hail and hoppers brought him down
He gave it up and moved to town
And Emmet Pierce the other day
Took a heart attack and died at forty two
You could see it coming on
Cause he worked as hard as you....

In an hour, maybe more, you'll be wet clear through
The air is cooler now, Pull your hat-brim further down
And watch the field behind the plow turn to straight dark rows
Put another seasons promise in the ground

And if the harvest's any good
The money might just cover all the loans
You've mortgaged all you own
Buy the kids a winter coat
Take the wife back East for Christmas if you can
All summer she hangs on
When you're so tied to the land

For the good times come and go, but at least there's rain
So this won't be barren ground when September rolls around
So watch the field behind the plow turn to straight dark rows
Put another seasons promise in the ground

(Boy Stan could write and sing em mates)
