Abstract
A planter for planting disk-shaped environmental seed cells which are formed of low-density readily-crumbled, compressed pulverulent material. The planter apparatus comprises a planter chassis supported from a tool bar of a tractor and pivotally supported thereon and resiliently urged at each end into contact with the ground. The planter comprises means for separating seed disks in the hopper and transferring seed cells therefrom in a file along a pair of inclined rollers driven in the same direction to dispense the seed disks individually through a chute into a furrow formed by a furrow shoe. The row of seeds is then compacted by a packing wheel which is also resiliently urged into ground-engaging contact from the support bar and serves to drive the separating and conveying rollers on the planter.
