All-purpose openers feature wide set half-inch parallel links for better depth control and accuracy in seed placement. Down pressures can be easily adjusted from no-till to conventional seeding without tools. 15" diameter x 3 1/2-mm “Heads Up” opener blades eliminate pairing of rows, premature leading blade wear and side loading of bearings. 

9300, 9400, 9500 series drills


The single-arm-mount conventional openers are mounted at an 8" stagger to promote residue flow through the seeding system. The single-point mount bearing is protected by UHMW bearings to prevent wear and reduce service time. The pneumatic down pressure system maintains an even down pressure on all row units.

9600 series drills


The all-welded seed hoppers are constructed of heavy 16-gauge steel with 3/16" thick end plates. The bolt-in hopper bottoms allow multiple row spacing using the same hopper.

9300 series (2.4 bu.), 9421 & 9600 (3.0 bu.) series, 9400 & 9500 series (3.75 bu.)


The infinitely variable meters are very gentle on seeds and provide a continuous flow of material, unlike fluted meters that drop seed in groups. This design has a better singulation effect than dumping small groups of seed (as in fluted meter operations). Rates are easily changed with a lever adjustment system on each hopper system. A small-seeds (legume) seeding hopper can be added to all models.

Seed Meter: All models.
Adjustment Lever: 9435, 9531, 9600 series


Sunflower 9000 Series drills feature an automatically locking walk board. Lift the walk board to the raised position and the lock will engage. The walk board is deep and the ladder folds over rather than under it. Attached to the ladder mount is a folding handle to assist the operator in mounting the walk board.

Walk Boards: All models.
Assist Handle: 9435, 9531, 9600 series


Heavy-duty 3/8 x 7 x 7-inch main frames are coupled to a 3/8 x 3 x 5-inch opener frame to create a sound foundation for all Sunflower grain drills.
