Abstract
Abstract An improved seed planter for a chisel plow includes a boot connected by a pair of leaf spring rods to the vertical shank of the plow. A bracket for connecting the spring rods to the boot and for gauge or press wheel attachments is detachably coupled to the rear of the boot by a quick-releasing pin that engages apertures in tabs affixed to the boot. The tabs mate with slots on the bracket. Thus, the depth of the boot may be regulated independently of the spring rod bias.
