Double-Shoot, Single Pass Implement
A planting unit for depositing fertilizer and seed in a single pass, double shoot manner includes a rotating disc that cuts a furrow in a planting surface and a trailing seed boot, having a cutting edge, that cuts a vertically and horizontally offset trench in the furrow to form a seed bed in the planting surface. The disc has a mounting frame for mounting the disc to a linkage assembly that is, in turn, coupled to a toolbar mount. The seed boot is also attached to the mounting frame. This common attachment provides a relatively short and compact device without sacrificing fertilizer and seed stratification.

21 . A double-shoot, single pass implement for separately depositing fertilizer and seed with horizontal and vertical stratification onto a planting surface, comprising:
a toolbar configured to be coupled to a towing vehicle which is designed to pull the frame along the planting surface with a generally longitudinal line of travel;
a plurality of planting units, each of which is connected to the toolbar by a respective linkage assembly; and
wherein each planting includes:
a disc mount coupled to a corresponding linkage assembly;
a rotatable disc mounted to the disc mount and configured to cut at an angle into the planting surface to form a fertilizer trench;
a fertilizer tube having an outlet generally adjacent the rotatable disc;
a seed boot configured to cut a seed trench offset from the fertilizer trench, the seed boot including a seed tube having a forward cutting edge and an outlet rearward of the fertilizer tube;
a packing wheel trailing the seed boot and configured to pack the fertilizer trench and the seed trench; and
a mounting arm extending generally rearward of the disc mount, wherein the packing wheel and the seed boot are coupled to the mounting arm.
22 . The implement of claim 21 wherein the seed boot further comprises a tab connected to the seed tube generally opposite the forward cutting edge and extending rearward of the seed tube outlet.
23 . The implement of claim 22 wherein the seed tube outlet is offset laterally and vertically from the fertilizer tube outlet.
24 . The implement of claim 23 wherein the tab is configured to limit seed dispensed from the seed tube outlet from being deposited into the fertilizer trench.
25 . The implement of claim 24 wherein the tab has an edge angled to encourage seed deposited by the seed tube outlet toward a tip of the seed trench.
26 . The implement of claim 22 further comprising a packing pressure control associated with the packing wheel and operative to vary the packing force applied by the packing wheel.
