tough/hard/long row to hoe, a

A difficult course to follow; hard work to accomplish. This metaphor comes from nineteenth-century America, when most people lived in rural areas and cultivated at least some land. David Crockett used it in his Tour to the North and Down East (1835): “I never opposed Andrew Jackson for the sake of popularity. I knew it was a hard row to hoe; but I stood up to the rack.”
