Abstract
An improved grain drill having individually mounted disks with disk boots. Seed tubes are suspended between each disk and boot. The disks are mounted on disk arms. The disk arms are biased by coil springs which urge the disks into the ground surface. The tension applied by the coil spring on the disk can be increased by adjusting the spring disposed on an adjustable spring tension arm integrally attached to the disk arm.
