Productive seedbox capacities
Seedboxes have a large capacity for longer intervals between stops for refilling.
|Drill||Total box capacity||L/m (bu/ft)|
|4.6-m (15-ft) model||1480 L (42 bu)||321.7 L/m (2.8 bu/ft)|
|6.1-m (20-ft) model||1409.6 L (40 bu)||231.1 L/m (2.0 bu/ft)|
All boxes are plain grain with a large, single lid for accessing the seedbox.
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.
