According to his ideals of continuity and economy of labor, Thomas Jefferson preferred to spread the activity of plowing over the whole year and, whenever possible, he tried to make a single plowing serve a double purpose. In 1794, for instance, his rotation plan called for combining the actions of turning under the vetch with the "flush-plowing" for the potatoes and peas.1

The Pennsylvania barshare plow was the form Jefferson preferred. A "short & light" one he bought for eight dollars from George Logan of Philadelphia was the model for Monticello's plows.2 And, from the early 1790s, the moldboard of choice was Jefferson's own moldboard of least resistance. He declared a barshare plow with his moldboard made at Monticello in 1810 to be "the finest plow which has ever been constructed in America."3

Jefferson's slaves became accomplished plowmen (and women). They began their training early. Jefferson said that thirteen-year-old Robin "works well at the plough already." The Monticello harvest records indicate that the female farm workers did some of the plowing. Jefferson's plan for the 1796 wheat harvest reserved eight laborers to "keep half the ploughs a going": Rachel, Mary, Nanny, Sally, Thamar, Iris, Scilla, and Phyllis.4 Jefferson wrote his overseer in 1818 that, "when slack of work," the female spinners "might go to the plough."5

Among the documented references to plowing found in Jefferson's letters and records are the following.
