Abstract
A seeder implement (125) includes a fork (146) having a first spindle support arm (150) that supports a first spindle (164) and a second spindle support arm (152) that supports a second spindle (168). A first disk (160) is supported on the first spindle (164), wherein the first spindle (164) is oriented in a first orientation and at a first acute angle relative to a lateral line. The first disk (160) is oriented at a second acute angle relative to the ground surface. A second disk (166) is supported on the second spindle (168), wherein the second spindle (168) is oriented in a second orientation and at a third acute angle relative to the lateral line. The second disk (166) is oriented at a fourth acute angle relative to the ground surface. The first disk (160) is longitudinally offset ahead of the second disk (166), and there are no structural components between the first and second disks (160, 166) other than the first and second spindles (164, 168). In one embodiment, a packing wheel (142) is disposed to close and compact furrows opened by the disks (160, 166) and is disposed in the same orientation as one of the disks (160, 166).
