'hae' = have; muckle = many

I hae warked on farms an' frae the start
The muckle horse's won my heart
Wi' big broad back they proudly stands
The uncrowned kings o' a' the lands
An' yet for all their power an' strength,
They're as gentle as a summer's wind
CHORUS
So steady, boys, walk on;
Our work is nearly done;
No more we'll till or plow the fields --
The horse's day is gone,
And this'll be the last trip home,
So steady , boys, walk on.
Now you'll hear men sing the songs of praise
Of Arab stallions in a race
Or hunters that vie with the hounds
To chase the fox and run him down
But none of them compare, I vow
Tae a workin' pair that pulls the plow,
Chorus
So steady boys walk on
our work is nearly done
no more we'll till or plow the fields
our work is nearly done
and this will be our last trip home
so steady boys walk on.

An' o'er the years I've plied my trade
And' a' the fields we've plowed and laid
I never thought I'd fear the time
That a Clydesdale's work would ever end
That progress runs its driven course
And tractors hae replaced the horse
Chorus
As we head back the friends that line the road
To be there one last time
for nane o' them wid want tae miss
The chance to see us pass like this
They'll say they saw in years tae come
The muckle horses' last trip home
