There are four general plans, or methods of plowing fields. These are: (1) to plow from one side of a field to the other; (2) to plow around the field; (3) to plow a field in lands; and (4) to start the plowing in the center of the field.
All other aspects being equal, the primary difference in plowing, comfortably, with a single horse is that the animal walks on unplowed ground immediately adjacent to the previous furrow, rather than in the furrow. This will cause the point of draft at the shoulder to be somewhat higher and will dictate hitching longer and/or higher than with the animal walking down 5 to 8 inches lower in the furrow.
