This ad shows clearly the seed boxes where the planter lids would have been placed. They are directly above the blades. Note also that this is a two-person model. One person would sit in the back and handle the horses, the other would sit on the front seat and drop the seeds by lever. The front, round seats are rare, partly because few two-person plows were manufactured after check-row planters became the fashion. This advertisement was provided by Martin Wilkerson, who co-authored the guide book Value Guide of Collectible Planter Lids and Markers.
