Specifications.docx

This is a specifications document for a 28-foot conservation no-till drill required by the Northwest Sustainable Agroecosystems Research Unit under the Department of Agriculture Agricultural Research Service (Solicitation Number 1232SA26Q0479). The drill is mission-critical equipment intended to replace an aging 2010 15-foot Horsch drill and will be used for small- and large-scale agricultural research, including seeding crops ranging from canola to garbanzo beans, applying liquid fertilizers, and applying variable rate seed and fertilizer applications per wing section.

The equipment must include a 14-foot mainframe with two 7-foot hydraulic wings, capable of operating the mainframe alone while other sections are winged up, and feature three independent seed controllers for variable rate capability per wing/section. The drill must be equipped with 28 side-mount shank openers in paired row configuration with dual PW configuration, plus 28 additional Dutch openers at 12-inch spacing, a 3-inch clean-out auger, 8-foot fill auger, and 100-bushel seed box. Critical compatibility requirements include integration with the Trimble TMX 2050 guidance and variable rate control system for both seed and liquid controls. Additional specifications require active hydraulic down pressure arms with control system, capability to apply deep band and starter fertilizer, ability to switch to double disk openers, and a transport width of 18 feet or less with drawbar hitch compatibility.
