<p>This invention consists of a tractor drawn planter which automatically deposits equally spaced sprout bearing plugs of specially prepared nutrient soil, into the ground. It is made of a rectangular framework having two rear wheels upon which it rides and a flexible hitch for attachment to the tractor. A tank equipped with an agitator, a plug size measuring device, and a discharge tube, contains the plug mixture. Inside, the discharge tube is provided with doors which allow the passage of the plug, at predetermined equal intervals. These doors are controlled by a spring loaded solenoid which is in turn controlled by electrical make and break contact points powered by the tractor battery. A floating shoe digs a furrow into which the plugs are dropped, and two spring loaded converging wheels in the rear of the frame cover and tamp down the seeded furrow. Rotation is provided to the agitator, the plug measuring device, and the electrical contact points by a train of chain connected sprockets from a takeoff from the rear wheels of the planter.</p> |
