Double-disk furrow openers

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 152.4-mm, 190.5-mm, and 254-mm (6-in., 7.5-in., and 10-in.) row spacings. The 152.4-mm (6-in.) spaced drills have nominal residue flow in minimum till conditions. The 190.5-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 6.35-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.
