Get Accurate Placement and Higher Yields
Higher yields can be gained when you match the right opener to your conditions to achieve accurate seed and fertilizer placement. Case IH offers two openers -- Stealth® and Nok-onthat deliver successful seeding in your conditions.

Stealth Opener System

  • System offers a choice of low-disturbance knife tips or a selection of spread tips for single-shoot applications
  • Stealth double-shoot side band or paired row attachments deliver one-pass seed and fertilizer placement
  • Replaceable tips let you match the right opener to the job and help you manage wear


Nok-On™ Opener System

  • Quickly switch sweeps, along with either a narrow or wide opener, to add maximum versatility to your seeding system
  • Fine-tune your product spread width with an adjustable spread boot option to match your choice of sweeps and packing


Packing Systems

Wide Range of On-Row Packing Choices
To improve germination, Case IH offers a wide range of on-row packing choices to match your seeding style, opener and soil conditions. You can choose from steel, pneumatic or semi-pneumatic packing wheels--each geared to fit specific conditions.

In-Line Gang Packing System

Wheel Options

  • Steel press wheels: Ideal for sandy and rocky soil conditions. A V-profile concentrates packing pressure onto a smaller area for higher pressure on the seed. Available in 3.5 in or 4.5 in (8 cm or 11.4 cm) widths.
  • Semi-pneumatic rubber press wheels: Ideal for heavy, sticky soils. A flat profile rides over a wider area for less packing pressure and flex to shed buildup. Available in widths of 3 in, 4 in or 5.5 in. (7.6 cm, 10.2 cm or 14 cm).


Shanks & Trips

Protect Your Openers and Achieve Consistent Depth
Match shank and trip styles to your operation so you protect valuable openers, get maximum clearance for tripping over obstacles and effective penetration for consistent depth. Choose from two shank styles and two trip options to create the air drill that's right for your operation.

Shank Designs

  • The rugged C-shank design can be used with a wide range of opener styles
  • Vertical Edge-On shanks are available for the Flex Hoe 700
  • When used with the Stealth®, the Edge-On shank creates ultra-low soil disturbance
  • Both shanks allow a wide array of openers, sweeps and attachments


Trip Options

  • Choose 350-lb. (149-kg) trips for most soil types
  • For rugged conditions and double-shoot applications, select 550-lb. (249-kg) trips
