Here is a closer chord progression to my ear.
Half-step down tuning (Eb, Ab, Db, Gb, Bb, Eb)
[Intro]
G D
G D
[Verse 1]
G C
Well I heard he needed some help on the farm
D C
Somebody with a truck and two strong arms
G D
Not scared of dirt and willin' to work
C D
till the sun goes down
G
So I pulled up and said I'm your man
D
I could start right now and we shook hands
G
He said the fence needs fixin',
D
the peaches need pickin'
C D
And the cows need bringin round
[Chorus 1]
G D
I was haulin' hay, I was feedin' the hogs
G D
and that summer sun had me sweatin' like a dog
Am
So I cooled off in the creek
G D
then it was back to work in the dag gum heat
G D
I was cussin' out loud, thinkin' bout quitin'
G D
Lookin' back now I'm sure glad I didn't
Am Cadd9
Cuz just when i thought it couldn't get no hotter
C D
I caught glimpse of the farmer's daughter
[Verse 2]
G C
She was just gettin' home from Panama city
D C
She was all tanned up and my kinda pretty
G
When her eyes met mine
D C
I was thinkin' that I would sure love my job
G C
As the days got shorter our talks got longer
D C
The kisses got sweeter and the feelings got stronger
G D
So we'd hop in the truck and get all tangled up
C
Every chance we got
[Chorus 2]
G
We were down by the river all night long
D
When the sun came up I was sneakin' her home
Am
And draggin' my butt to work
C D
With the smell of her perfume on my shirt
G
I'd be on the tractor she'd be on my mind
D
With that sun beatin' down on this back of mine
Am Cadd9
Just when I thought it couldn't get no hotter
C D
I fell in love with the farmer's daughter
[Bridge]
Am D
We got married last spring
Am D
Woah and there ain't no better life for me
[Chorus/Outro]
G
Im still haulin' hay and feedin' the hogs
D
And that summer suns has me sweatin' like a dog
Am
So I cool off in the creek
C D
And she brings me outta glass of sweet ice tea
G
Im on the tractor and shes on my mind
D
And I cant wait til its quittin' time
Am Cadd9
And just when I think it cant get no hotter
C D
I come home to the farmer's daughter
G D
D G
Yeah the farmer's daughter
