ABSTRACT:
A cultivator-material dispensing combination includes a soil-working member that rotates about a horizontal axis forwardly, relative to the direction of travel, to displace soil over the top of that member to a screening at the rear thereof. A seed dispensing hopper has conduits that are supported on a hood that overlies the member and extends to the rear thereof. Material is metered from the hopper through outlets at the conduits' lower rear sides. Drive to the hopper is via a one-way transmission that is driven by a rear roller only when the combination moves forwardly. A further roller can be positioned to the rear of the first mentioned roller and a fertilizer hopper feed also driven to dispense material to the worked soil.
