Simply by opening or closing seed openers, the Disc Drill SD can be configured for a variety of spacing possibilities for 30-inch rows, such as 6"/9", 6"/24", 9"/21" and 15"/15". This versatility is great for seeding small grains, pulse crops, cover crops, soybeans and canola, as well as applying fertilizer.
Placement of fertilizer in relation to seed is critical to planting success. Concord’s Disc Drill SD opener features an optional mid-row bander to apply liquid, dry or NH3 fertilizer directly in between the seed trenches created by the drill’s two opposing discs. The discs also provide the unique capability to throw soil back over the fertilizer immediately after its application — no other drill on the market is capable of capturing and retaining NH3 with such a high degree of efficiency.
Discs are spaced 6 inches apart, with the optional mid-row banding placing the fertilizer only 3 inches from each row and up to 1.5 inches below the seed. This puts the fertilizer exactly where it should be to feed the seeds, and not the weeds. Competitive drills typically space rows 10 inches apart, putting fertilizer a full 5 inches away from the seed.
Concord uses a patented opposing single-disc design that is remarkably simple to operate and maintain. Each opener has just two bearings that need to be greased once a year. Since it requires no in-season maintenance, you can work nonstop in the field. Even more, Concord’s Disc Drill SD has 75 percent fewer moving parts than competitors, meaning there are fewer things that can go wrong.
The opposing discs push and lift the soil between the rows to be releveled. This leaves a black seedbed for quicker warming and improved seed-to-soil contact over competitive systems.
A rear packer tire helps to properly close the furrow and capture NH3, with seed on each side of the tire. The packer tire is also used to gauge depth, instead of gauge wheels, which can cause sidewall compaction.
