Double-disk opener Double-disk opener
Double-disk openers create a furrow in which seed is placed. They work best in a prepared seedbed and leave the field relatively smooth, with minimal soil throw.
The double-disk openers are available with 150-, 190-, and 254-mm (6-, 7.5-, and 10-in.) row spacings. The 150-mm (6-in.) spaced drills have nominal residue flow in minimum till conditions. The 190-mm (7.5-in.) spacing is recommended for wet, sticky soil conditions such as the Red River Valley.
Cast-aluminum boots are standard equipment. Openers come with a zigzag pattern, with alternate short and long drawbars, to provide good trash flow in varied field conditions. The alternating of blades with a right/left leading-edge offset improves penetration.
Blades are offset with a 6-mm (1/4-in.) leading edge, and the pinch point is close to where the blades meet the soil for better penetration and residue cutting.
