Abstract: A frame is provided from which front and rear pairs of opposite side wheels are journalled. A prime mover is mounted on the frame and drivingly connected to at least one pair of the wheels thereof. The frame defines a longitudinal center line and the wheels are disposed in four vertical planes paralleling the center line and spaced equally apart transversely of the frame. The wheels include narrow outer peripheral portions adapted, due to the gross weight of the planter, to form narrow depressed tracks in cultivated ground over which the planter travels and each of the wheels has seed planting structure operatively associated therewith and to discharge seeds into the depressed ground tracks at a metered rate.
