YA Fiction Book about a boy who doesn't have a name, works as a fieldhand

[Slate]

Book is about a boy without a name who works as a day laborer in fields. Book is set in older times, his daily wages were in dollars and cents. At some point a girl makes up a name for him, but is later killed by a piece of farm machinery. It is set in America, likely the west. I read it around 2010 or earlier, but the book is likely much older. Any help is appreciated!

This made me think of a book that I've suggested a couple of times. Not sure about the machinery killing his friend part but I'm mentioning it just in case because of the no name detail:
The Least One by Borden Deal

That looks like a good read, but unfortunately is definitely not the book I'm trying to find. Thanks though!

Summary of The Loner from another thread: "The boy" can't remember having a mother or father. He's worked in the fields as long as he can remember, traveling with anyone who will give him shelter in exchange for his earnings. Once, he becomes close enough to a migrant girl that she almost gives him a name, but she's killed when her long yellow hair is caught in a potato-digging machine.
