ABSTRACT OF DISCLOSURE A planting assembly is disclosed which com- prises a tubular support arm for carrying a plowshare and for conveying seeds pneumatically. The front end of the support arm is pivotally mounted about a horizontal pivot pin perpendicular to the direction of displacement of the assembly. A spring acts in a vertical plane to exert a substantially constant force against the plowshare to dri- ve it into the ground. The pivotal mounting of the support arm comprises a spring-loaded open-ended yoke for permitting rocking about a horizontal plane when the horizontal couple exerted against the support arm exceeds a predetermined value. The front end of the tubular support arm is connected to a supply of air entrained seeds and the rear end to a cyclone separator separating the seeds which proceed through a conduit to the furrow cut by the plow- share the main stream of entraining air which is exhausted to the atmosphere.
