Seed in style

02/04/2013 @ 4:43pm

Designed as a single-pass seeding system, the Sunflower 9700 Series air-till drill features the ribbon-seeded planting style. This attribute allows the drill to open the soil, slice out weeds, place seed and fertilizer, and finish by packing the soil to preserve moisture and to optimize seed-to-soil contact.

“The ribbon-seeding style of the 9700 Series was long ago proven to produce yields that consistently outperform conventional row drills,” says Tom Draper, Sunflower seeding and tillage product marketing manager. “By pairing the SF9730 60-foot model (which is our largest) with a Sunflower 9900 Series commodity cart, farmers will have a unit that will cover many acres quickly and really help optimize their productivity and yields.”

With 10-inch row spacing, the drill places seed in a 5-inch-wide ribbon, with only 5 inches between rows. Due to the heavy frame and wide packing wheels, this implement delivers proper seed packing to help farmers achieve uniform emergence of small grain crops.

To help ensure that row units penetrate even the toughest soil conditions, this machine is built heavy and durable, and it weighs more than competitive drills. The frame and wings rest on walking tandems to provide uniform seeding depth and to minimize depth variation across the width of the machine, which can occur when passing over clods or ridges.

The drill is also designed to ensure uniform seedbed packing across the machine's width regardless of field obstacles. To achieve this, packing wheels are mounted on walk beams, with every walk beam separately spring-mounted to the drill frame. The wide packing wheels ensure the best possible firming of the seedbed to conserve soil moisture and to enhance uniform crop emergence.

By leveling the frame of the 9700 Series drill, it's easy to set a uniform seeding depth. The depth-control collars on the packer wheel-frame lift cylinders make it easy to see that each cylinder is at the correct depth. The rephasing lift cylinders ensure the drill returns to the level position after raising and lowering.

To maximize flexibility when placing fertilizer and depending on the choice of seed openers, fertilizer can be placed with the seed, or it can be split between the seed ribbon and below or to the side of the seed.

The drill's 650-pound trip-spring shanks help seed openers stay firmly in place and allow opener assemblies to move over fixed obstacles without disrupting row alignment.

The machine can be equipped to apply anhydrous ammonia. Customers can choose from other options, including:

  • Disk levelers for a smooth field finish regardless of field speed.
  • Tillage coulters to slice through heavy residue.
  • Wireless seed tube blockage sensors.

Available in 40-, 50-, and 60-foot widths, the drill has the ability to handle a range of production systems. The suggested prices are as follows:

  • $114,060 for the 40-foot model
  • $147,010 for the 50-foot model
  • $158,559 for the 60-foot model
