Abstract
The seeder apparatus includes a first hopper for dispensing seeds onto a conveyor mechanism to be moved thereby to an entry nip between a rotary brush and the conveyor mechanism for propelling the seed downwardly at the discharge end of the frame on which the hopper is mounted. A shield assembly is mounted to the frame discharge end portion to minimize the effects of wind on the trajectory of seed or other material being propelled to the ground by a brush and conveyor mechanism. In one embodiment, a metering gate extends vertically in its closed position relative to the conveyor mechanism, the metering gate controlling the rate of dispensation of seed being moved to the entry nip. In a second embodiment, the seed hopper is mounted to a top dresser hopper whereby either seed from the seed hopper and/or dressing material from the top dresser hopper may be moved by the conveyor mechanism to the entry nip, with a top dressing metering gate being provided for controlling the rate of dispersion of material from the top dresser hopper to the entry nip.
